Which teeth whitening is the safest and most effective: expert opinion

What is the safest and most effective teeth whitening? Modern dentistry has quick transformation methods that can make your smile beautiful, your enamel strong, and your mucous membranes healthy. Almost all patients dream of a snow-white smile, because it adds confidence.

There are many ways to lighten the enamel layer. Each of them differs in the technology of processing hard tissues, efficiency, and speed of achieving results. They all have their advantages and disadvantages. Only a doctor can help you choose the best option.

Causes of darkening of enamel

Eating foods and drinks containing dyes;
Having bad habits such as smoking;
Past illnesses;
Age-related changes in the human body.

If it is possible to compensate for the insufficient whiteness of teeth associated with the individual characteristics of the tooth structure only by using crowns, veneers and onlays, then compensation for darkening caused by external factors does not require such serious intervention. Modern cosmetic dentistry has a fairly large selection of methods and means for whitening tooth enamel.

In the question “ what is the safest and most effective teeth whitening ,” it is worth considering that the possible risks and complications of such procedures cannot be underestimated. Like any intervention, whitening has its indications and contraindications.

Contraindications for teeth whitening

Age under 18 years;
Individual intolerance (allergic reactions) to the components of substances used in the bleaching process;
Pregnancy and breastfeeding;
Completing a course of chemotherapy;
Undergoing treatment with light-sensitive drugs (tretinoin, tetracycline antibiotics, etc.);
Untreated caries and other destruction of dental units;
Wedge-shaped tooth defects;
Exposure of the neck of the dental units;
Artificial crowns;
Areas that have undergone filling or restoration, located in the area of intended bleaching;

Risks of bleaching

Increased sensitivity of tooth enamel;
Changes in the structural state of the enamel;
Possibility of premature wear of teeth;
Changes in enamel strength, increased fragility and brittleness;
Irritation of the mucous membranes located in close proximity to the procedure site.

It is in connection with the above factors that many people are interested in the question of which teeth whitening is the safest and most effective . There are two main whitening options:

Dental;
Homemade.

In both cases there are nuances that must be taken into account.

Difference between teeth whitening and teeth lightening

Before choosing the safest and most effective method of teeth whitening, it is worth understanding the difference between teeth whitening and teeth lightening - what is the difference between them? The main differences between these concepts come down to the following points:

>Teeth whitening involves a chemical reaction to break down plaque. During the procedure, special oxidizing agents are used that penetrate the upper layers of enamel, giving a light shade to the teeth.
The whitening procedure is different in that it is less chemically destructive and does not use many chemicals, however, the result will not be as effective and long-lasting as with teeth whitening.

By lightening, dentists mean gentle mechanical and abrasive methods of removing plaque. They do not use hydrogen peroxide and other compounds, but the result will not be as effective and durable. Based on this, we can conclude that teeth whitening has a number of bad consequences: uneven color, increased tooth sensitivity, and in rare cases, burns to the tissue of the lips or gums. However, today there are many safe and effective ways to whiten teeth , both in dentistry and at home.

Example No. 1

Before her wedding, a young girl tried to whiten her teeth using conventional methods, but she was not happy with the result.

We selected the appropriate shade using computer modeling

and performed composite whitening in 3 hours.

A new snow-white smile will forever remain in your wedding photos.

Methods of teeth whitening in dentistry

In this case, all procedures are carried out by a specialist in a clinical setting, using professional tools, equipment and techniques.

Mechanical whitening method

The whitening process uses specialized tools and attachments that effectively remove plaque and tartar deposits. At the moment, the most common methods of mechanical cleaning are recognized: ultrasonic cleaning and Air Flow sandblasting. It is difficult to call such procedures whitening, since they first of all remove deposits from the surface of the teeth and restore their natural color, eliminating nicotine plaque and the remains of coloring food fragments. This type of treatment involves exposing the tooth to a powerful, focused water-air jet containing abrasive particles. As a result of processing, the enamel is lightened by 6-7 tones and acquires a polished surface.

This type of teeth whitening is quite effective , as you can see a fairly quick effect and a low price.

Laser whitening

The essence of the procedure lies in the interaction of hydrogen peroxide and a laser beam, which serves as a kind of amplifier of the effect of the substance. In addition to the above, the laser makes the procedure the safest due to its ability to accelerate the process of peroxide penetration into the tooth enamel.

Stages of the procedure:

Examination and assessment of the condition of the oral cavity for the presence (absence) of contraindications.
Removing plaque and tartar deposits;
Applying a gel containing high concentration hydrogen peroxide.
Laser treatment at the rate of 30 seconds of exposure to each dental unit.
Cleaning the oral cavity.
Mineralization of enamel using fluoride-containing preparations.

Why is laser teeth whitening effective?

Short time of impact. Unlike light whitening, which can last from 1 to 2 hours, the laser whitening procedure takes on average 30-40 minutes.
High quality whitening, allowing you to achieve quick results with lightening by 8-10 tones on the Vita scale, and long-lasting results, varying from 3 months to a year or more.
Relative harmlessness. The speed of exposure of the composition and the laser beam allows you to reduce the harmful effects on the enamel.
Laser exposure has a disinfecting effect, which is the prevention of many diseases, including caries.
Several laser treatments can not only whiten teeth, but also give them smoothness, due to which further staining of the enamel is significantly reduced.
Mineralization, carried out at the end of the procedure, does not increase the sensitivity of the enamel, on the contrary, it strengthens and revitalizes it.
Painless procedure.

Disadvantages of laser teeth whitening

Relative negative aspects include the fairly high cost of the procedure.
Smoking may minimize the results.
An incorrectly performed procedure can lead to burns of the mucous membranes, damage to the enamel and increased sensitivity. the safest and most effective teeth whitening service, you can contact our clinic

Contraindications for laser whitening

Deep and extensive damage to the enamel (caries, cracks, erosion, etc.);
Availability of corrective and restorative systems (braces, veneers, dentures);
Inflammation of the gums;
Exposure of the root part of the teeth.

Photobleaching

The method is based on the combined effect of a specialized brightening composition containing hydrogen peroxide and urea and a light emitter that acts as an activator.

The following light sources can be used:

LED lamps, cold glow. This type of lamp is recognized as one of the safest;
Halogen lamps provide cold light, minimizing tissue injury;
Ultraviolet lamps. Such lamps are now not often used, as they give an excessively heating effect.

The type of lamp is selected depending on the individual characteristics and type of structure of the teeth. One session of such whitening can last from 30 minutes to 1-2 hours, depending on the complexity, and lighten the enamel by 7-10 tones. The maximum effect is achieved after 3 sessions.

Photobleaching technologies

Zoom technology. An important nuance of this technology is the addition of calcium phosphate to the lightening composition, which has a strengthening effect on the enamel. In this case, transillumination is carried out with an ultraviolet lamp. The maximum efficiency of this technology is lightening by 12 tones. UV lamps have a pronounced warming effect, but the high efficiency of teeth whitening of this type makes this technique quite popular;
Amazing White technology. The targeted effect of the LED lamp breaks down peroxide molecules into oxygen, which brightens dentin and water;
Beyond Polus technique. Involves a combination of halogen and LED lighting. Such interaction makes the procedure more gentle and safe. The procedure includes three cycles, 10 minutes each. The results obtained can last up to 12 months;
Luma Cool technology. LED lamps with cold light are used. The session consists of three cycles, lasting 8 minutes. Exposure to LEDs is one of the safest and most gentle. The achieved result can last for several years.

Indications for photobleaching:

Uniform darkening of the enamel without spots or pronounced stripes.

Contraindications to the procedure

Pregnancy and breastfeeding;
Age less than 18 years;
The presence of thinned enamel with increased sensitivity;
Carious lesions of dental tissues.

Benefits of photobleaching

Rapid achievement of results that last for a period of 1 to 3 years;
Photo whitening is extremely one of the safest methods of teeth whitening .

Negative sides

Increased sensitivity of the enamel during the first time after the procedure;
Does not have a brightening effect on foreign inclusions and systems (fillings, veneers, dentures);
Quite a high price.

Photobleaching process

Examination of the patient’s oral cavity and assessment of the patient’s condition in order to identify possible contraindications;
Removing plaque and tartar deposits;
Isolate the gums with a sterile film or protective gel and a lamp to prevent burns and irritation that may result from contact with the bleaching agent;
The eyes of the patient and the doctor are protected with special glasses;
Application of whitening gel. The gel is distributed in an even layer on the teeth of both jaws;
The gel is irradiated by a lamp. The average session duration is about 30 minutes. The exposure time may decrease or increase depending on the desired result and the original shade;
At the end of the procedure, the remaining gel is removed from the oral cavity;
The number of repeated treatments is 3-4 sessions, depending on the desired result. The assessment is made using the Vita scale;
The patient receives advice on care, allowing the results to be maintained for as long as possible.

On average, the result of such treatment can last from 1 to 3 years.

Chemical bleaching

The method is based on the impact on darkened enamel with various gel-like agents, which include carbamide or hydrogen peroxide, the percentage of which can vary from 10 to 45%. The methods of photobleaching and laser cleaning described above can essentially be considered varieties of chemical techniques, since all three methods use gels containing peroxide.

The main distinguishing feature of these methods is the mandatory presence of a laser or light lamp, which makes it possible to achieve the desired results when using peroxide in much smaller proportions. While the chemical method does not involve the use of auxiliary equipment, whitening occurs solely due to the composition applied to the surface of the teeth.

The chemical bleaching method is considered more gentle compared to laser or photo bleaching due to the absence of heating devices. However, the result of such bleaching is much less pronounced and amounts to approximately 5-6 tones. The procedure takes 60 minutes, and the achieved effect lasts from 1 to 1.5 years.

Indications for chemical teeth whitening

Darkening of the enamel as a result of consuming foods (drinks) containing aggressive dyes;
Tobacco smoking;
Darkening of the enamel as a result of long-term use of certain medications;
Age-related changes in enamel;
Damage to the enamel and its darkening as a result of injury.

Contraindications

The presence of high enamel sensitivity;
Serious damage to the enamel layer (cracks, chips);
Presence of untreated diseases of teeth and gums;
Individual intolerance to the components of the lightening gel.

Stages of the procedure

Examination of the patient’s oral cavity to determine the possibility of whitening;
Isolation of gums using protective pads to prevent gel from entering, which can cause a burn;
The teeth are isolated from the oral cavity to avoid saliva;
Application of gel. The composition is applied using a special brush, evenly and layer by layer;
After the required exposure is completed, the remaining gel is carefully removed.

Positive properties of the chemical lightening bleaching method

Quick result, the beginning of which is noticeable after 15 minutes, and the final result is visible after 30-60 minutes;
Relative safety, due to the absence of additional traumatic devices;
Painless procedure.

Flaws

The development of excessive reactivity on the part of the enamel is possible;
Selectivity of the method;
Risk of irritation or burn of the gums in case of contact with the bleaching composition.

Endobleaching (intracanal method)

Intra-canal bleaching, compared to the above, is a more coordinated measure and is used in cases where the darkening of the enamel is associated not with external, but with internal factors. The most common reason for endo-whitening is darkening of the tooth crown from the inside.

This can happen as a result of depulpation, the use of coloring filling materials, dental disease (pulp necrosis, pulpitis, pulp hemorrhage, hypercalcification) and serious injury to the crown of the tooth. The essence of the method is to inject a dye into the crown and then seal the entrance hole.

Indications for intra-canal bleaching

Age-related darkening;
Darkening associated with bad habits;
Incorrect treatment carried out earlier and causing darkening of the tooth from the inside;
Darkening associated with total injury to the internal tissues of the tooth.

Contraindications

Pregnancy and breastfeeding;
Age up to 18 years;
Periodontitis;
High level of enamel sensitivity;
Diabetes;
Thyroid diseases;
Advanced carious lesions;
Individual intolerance to the components of the composition;
Inflammatory diseases of the oral cavity.

Advantages of the method

Possibility of restoring the aesthetic appeal of teeth without prosthetics or installing veneers;
Minimum possibility of complications;
Relative painlessness;
High performance, allowing you to achieve whitening by 10-12 tones;
Relatively low cost;
Long lasting results.

Disadvantages of endobleaching

Using a drill;
The appearance of fragility with frequent use of the method;
Replacement of old filling material is required;
The procedure may require several visits to the doctor.

It should be borne in mind that this method requires more thorough preparation than those previously described. One of the first stages of preparation is an x-ray examination, which allows you to clearly assess the problem and condition of the teeth. After the examination, a thorough visual examination and complete sanitation of the patient’s oral cavity are performed.

Stages of endobleaching

Treatment of the oral cavity with an antiseptic;
Selection of a suitable shade of enamel;
Isolation of the tooth to be whitened;
Removing old filling material;
Thorough sanitation of the cavity;
Isolation of canal mouths using a special lining;
Introduction of a brightening agent into the prepared cavity;
Sealing with installation of a temporary filling.

A repeat procedure is scheduled after 7 days. A total of 2 to 4 visits may be required. When the desired result is achieved, the doctor installs a permanent filling.

Due to the fact that the intracanal bleaching method involves deep intervention, the recommendations that should be followed are more serious.

So, in the first 7-10 days after the procedure it is not recommended:

Give serious mechanical loads to the tooth being whitened;
Eat foods that are sharply contrasting in temperature;
Use viscous, enveloping foods and chewing gum;
Chew actively on the side where bleaching was performed.

Nuances you need to know before the procedure

It is often written on the Internet that restorative whitening is a non-invasive procedure during which the original structure and condition of the tooth are not disturbed, and the composite or onlays are simply glued to the patient’s enamel on top. But this statement is nothing more than a publicity stunt.

Imagine what the restoration will look like if you simply glue an artificial material on top of your teeth, which also has some thickness? Let's list the consequences:

the tooth made will protrude forward and stand out from the rest, it will increase in volume,
without preparing hard tissues, it will not be possible to hide existing defects, stains, irregular shape and curvature of the crown,
the area at the border of the material with the mucous membrane, if you do not make a smooth transition or ledge, will generally look unnatural, will become constantly injured and inflamed, since food debris and bacterial plaque will constantly clog into the resulting gap.

Before installing microprostheses, the specialist grinds the teeth.
Before carrying out restorative bleaching, the doctor carries out, albeit minor, grinding of hard tissues from the vestibular (anterior), cervical and lateral sides. This procedure is also necessary to level the relief and surface of the tooth and ensure a tight fit of the materials, as well as their high-quality and durable fixation. Only patients who choose original lumineers1 can avoid preparation - in this case, the doctor only slightly grinds the enamel and treats it with glue before installing the onlays.

The most effective teeth whitening at home

Teeth whitening at home is a fairly common type of hygiene care. The modern market offers a fairly rich assortment of whitening products that differ in effectiveness and price ranges, so it is definitely impossible to answer the question: “ what is the most effective teeth whitening at home ”? It is worth considering that all home remedies, both improvised and manufactured in industrial conditions, will not allow you to achieve the same dramatic results that can be obtained with professional whitening in a clinic. In addition, with careless and extremely intensive use of such products, there is a high probability of causing serious damage to tooth enamel and nearby tissues. This is due to the abrasives contained in pastes and other bleaching agents and the presence of irritating components, such as hydrogen peroxide. With frequent use, abrasive particles can thin the enamel and leave microdamages, which become a favorable environment for the accumulation of bacteria and staining particles. Hydrogen peroxide, if used incorrectly, can seriously injure mucous membranes, leaving burns and irritation.

Toothpastes with a whitening effect, gels, trays and pencils have gained the most popularity as some of the most effective ways to whiten teeth at home Currently, in pharmacies you can find various whitening pastes, which contain substances that gently and effectively remove plaque. You should use them no more than 1-2 times a week, since the abrasive particles contained in the paste spoil the enamel, and subsequently it can be easily stained by coffee, tea and other products.

Whitening dental strips

Whitening strips are one of the most affordable products that can be purchased at any pharmacy. At their core, these are narrow strips of polyethylene, with a layer of brightening composition applied to the inside, in which the main active component will be hydrogen peroxide with a content of up to 10%. The strips are sold in sets, which contain separate stickers for the upper and lower dentition.

There is nothing complicated in using the product: just attach the strips to the outside of the teeth and leave for half an hour. During this time, the brightening substance will begin to act, triggering chemical reactions in the enamel coating that will gradually destroy the colored pigments. Strips are used for teeth whitening in a course, the average duration of which can be up to 14 days. It is advisable to use the stickers twice a day - in the morning and in the evening, so the positive effect will come much faster.

If you believe the reviews of the strips from people who have tried them from personal experience, then there is no particularly pronounced whitening effect from their use, but there is a high probability of encountering negative side effects, among which buyers of the product mention burns and inflammation of the gums, increased sensitivity of teeth to to various external stimuli.

Which teeth whitening is the safest and most effective: summary

When choosing which teeth whitening is the safest and most effective , you need to understand that it is almost impossible to achieve high results without the risk of damaging the enamel or the tooth as a whole at home. That is why it is more advisable to entrust this procedure to professional doctors.

If we talk about the safest and most effective teeth whitening in dentistry, then it is hardly possible to answer this question unambiguously, since any method has its pros and cons. The choice of whitening method is selected individually and is based on many aspects and nuances.

The essence of the method

The peculiarity of restorative whitening is that the method allows you to give your teeth not only the desired shade, but also correct minor flaws (chips, cracks, stains, gaps between teeth). Please note that restoration methods do not affect the original color of the patient’s enamel and do not contribute to the destruction of unsightly pigment, as classical methods do, namely, they hide the defect. In this case, the patient has the opportunity to choose the color and degree of whiteness of the enamel, that is, he receives a predictable result, which is usually difficult to achieve with traditional lightening methods.

It is impossible to whiten chips and cracks in enamel using the usual method.

The purpose of restorative whitening is to improve the appearance and even correct the shape of row elements located in the smile area. The procedure is not carried out in the chewing area, since the materials used for it are not designed to withstand heavy loads.

The essence of the procedure for restorative teeth whitening comes down to the fact that the doctor applies artificial material to the frontal (front) surface of hard tissues or glues thin but very durable overlays that exactly imitate the color and shine of natural enamel. If the patient wishes, the specialist will always be able to remove, refresh or adjust the restorations, or select a new color.
