What to make a tooth crown from so that it lasts as long as possible

A crown fell out: what to do before seeing a doctor

So, the crown came off. You can’t immediately grab any technical glue you have at hand and try to glue it back. Some people make a big mistake using superglue. Its composition is very toxic and burns through living tissue. The dentist will not be able to reinstall a crown fixed in this way.

If a crown comes off, follow these recommendations.

• Wash the fallen crown with water, wrap it in a napkin and place it in a bottle or box so that it does not break before your visit to the dentist.
• Brush your teeth gently. Be careful not to damage the stump. Use rinse aid.
• Hold off on eating and drinking drinks (except water).
• Make an appointment with an orthopedic dentist as soon as possible.
• If pain occurs, take a pain reliever.

How to glue a fallen crown at home?

If it is not possible to visit the dentist in the near future, the fallen denture can be temporarily glued back. Pharmacies sell dental cement, which is used to secure a fallen-off denture.

• Mix the glue ingredients according to the instructions.
• Apply cement to the washed and dried crown.
• Put it on carefully. If the denture does not fit easily into place, do not try to force it in to avoid chipping the tooth.
• Press the crown onto the tooth with your fingers for 1 minute (without being too hard).
• Then close your teeth for 2 minutes.
• Remove remaining cement with a toothpick or dental floss.

This way you will protect the tooth stump from bacteria and damage while eating before going to the dental clinic. Avoid solid foods, brush your teeth twice a day, and use mouthwash. However, dental cement should only be used as a last resort. Don't delay your visit to the dentist.

What determines the service life?

On average, a crown can last 5-7 years, and a dental bridge - 7-11. No one can give accurate forecasts; this is influenced by many factors.

The main ones:

1. Materials used for manufacturing. The most durable structures are made of metal, but they have one drawback - an unattractive appearance. Metal-ceramic crowns are a kind of compromise between aesthetics and durability. There are other raw materials, each of which has its own advantages and disadvantages. However, when restoring anterior teeth, ceramics are the best option.
2. Specialist qualification. Precision manufacturing and correct installation play an important role. Only then does saliva and food not get under the prosthesis, the gums do not become inflamed, and the product itself fits without gaps or voids.
3. Fixation method. Crowns based on zirconium dioxide and metal-ceramics are attached to a special material – “cement”. Over time, it deteriorates, causing a leak. Structures based on lithium disilicate are fixed using a special technique, which ensures a strong connection and extends service life.
4. Care and daily hygiene. It is necessary to brush your teeth 2 times a day. For a more thorough cleaning, it is better to floss and rinse your mouth after every meal. It is recommended to have your teeth professionally cleaned by your dentist periodically.
5. Condition of the tooth. Often patients come when it has already been destroyed to the level of the gum or below. This does not allow the structure to be completely sealed, which means it will not last long.

As we see, durability depends on many factors, but the experience and qualifications of a specialist and the correctly selected method of restoring lost units play a big role.

Is it possible to put the old crown back?

Sometimes the doctor can replace the fallen crown in its original place. However, treatment tactics depend on the integrity of the prosthesis itself, the type of stump (pin, inlay, implant) and the degree of tooth destruction.

What to do if a temporary crown falls out

Temporary crowns are installed to protect the stump during the production of a permanent prosthesis. They are attached to temporary cement, which is gradually washed away under the influence of saliva. If a temporary plastic or ceramic crown falls out, contact your dentist to have it reinstalled. If this is not done and minimal damage appears on the stump, the permanent crown will not fit tightly and will quickly fall off.

The crown fell out, the tooth is intact

If the patient immediately consults a doctor and there is no caries on the tooth, the cost of installing a fallen crown will be minimal. The doctor will clean the stump and prosthesis from residual cement, and put the old crown in place. Small chips on the prosthesis are polished. If the damage is significant, a new crown is made.

What to do if a dental crown keeps falling out

If the crown falls off more than once, perhaps its size/shape does not match the stump or the installed pin is movable. Contact your dentist at the First Family Clinic of St. Petersburg. An experienced doctor will determine the cause of the prosthesis falling out and make the appropriate correction: in the first case, he will make a new crown, in the second, he will strengthen the support or install an inlay.

The crown fell out along with the tooth

If the tooth breaks off along with the prosthesis, but the roots are not damaged (an x-ray is prescribed for this), it is necessary to create an artificial stump using pins or an inlay, and install a new crown. The second option is desirable, since the tab is more stable than the pin. However, with curved root canals, its installation is impossible.

The crown fell out with the pin

This happens if the pin was installed too short or the patient exceeded the load on the teeth. Bacteria immediately penetrate the root canal. It is necessary to visit the dentist urgently, otherwise a cyst may form. If the pin falls out along with the crown, support for the new prosthesis is created using an inlay, provided that the roots are intact. It is stronger, and therefore will hold the crown better. If the pin is broken (a part remains in the canal) or the roots are damaged, they will have to be removed. The dentition is restored using an implant, bridge or removable denture.

The stump tab with the crown fell out

If the treatment is timely and the roots are not damaged, the doctor will make a new tab. If the roots are cracked or fractured, the tooth is removed and another type of prosthetics is recommended.

Implant installed, crown fell out

Medical tactics depend on the nature of the damage.

• The crown has become loose due to loose threads on the abutment - contact your dentist immediately. The doctor will tighten the screw, otherwise the metal structure may break.
• The crown has fallen off the abutment due to poor-quality cement - to prevent damage to the metal structure of the implant, immediately seek dental help. The doctor will perform the treatment and securely glue the crown into place. If the crown is damaged, a new one is made.
• The crown is cracked - a new one will have to be made. If the abutment is damaged (extremely rare), the screw must be replaced.
• The crown fell out along with the artificial root - this happens if a low-quality system was used, the prosthesis was incorrectly selected, or the installation technique was violated (for example, the implant is too tilted). In this case, the dentist waits for healing and implants a new prosthesis. Osteoplasty is sometimes required. If there is serious damage to the bone tissue, a bridge or removable denture is installed.

Important! Dental implants vary in the size and shape of the abutment and the type of connection. In some models, the screw and root part are monolithic. The patient must know exactly the brand of the implanted prosthesis.

Titanium implants rarely cause allergies. The engraftment process is complicated in patients who smoke, have diabetes, osteoporosis and other diseases. To avoid loss of the titanium root, before implantation, the dentist carefully examines the patient’s medical history and evaluates the possibility of installing an implant.

To ensure that the crown lasts as long as possible, contact dental centers with a good reputation. Read reviews from patients who had crowns installed at the First Family Clinic of St. Petersburg. Our specialists install high-quality dentures of various types and help in cases of loss of crowns.

Indications for use

The main reasons for the absence, for the elimination of which the dentist will suggest installing a crown on the tooth, include:

• destruction by 50% (both as a consequence of advanced caries and mechanical impact);
• the aesthetic side associated with the occurrence of chips, cracks, deterioration of color compared to the rest of the “brothers” in the series;
• damage to the coronal part (in other words, destruction of the installed prosthesis);
• critical abrasion - bruxism is a pathological disorder in which intervention will serve as protection for tissues.

Important! Bruxism is an involuntary grinding of teeth that occurs in people during nighttime sleep. First, the doctor will recommend undergoing a full diagnosis and treating the cause of the deviation, taking a course using a night guard, before direct placement.

Manufacturing

Crowns for temporary use are made using two methods: direct and indirect. In the first case, all manipulations are carried out within the walls of a dental clinic, and in the second - in a dental laboratory, where experienced professionals work. You can also purchase ready-made crowns, which can simply be fixed in the mouth using a fixing compound.

Composite dentures are usually installed at the front of the smile; this material allows for maximum attractiveness. The direct manufacturing method involves preliminary taking an impression from the patient’s jaw. To do this, the tooth is prepared and an adhesive-filled impression is attached to it. After taking an impression, the patient receives a finished plastic structure, securely fixed in the mouth. All that remains is to carry out the polishing and the patient can go home; the whole procedure does not take more than 2 hours.

Indirect method: first, the tooth is prepared and impressions are made. These impressions are sent to a laboratory where a temporary prosthesis is produced within a few days. In this case, the person will need to visit the dental clinic at least twice; at the last visit, the prosthesis will be installed.

Is it possible to put a crown on a tooth with a living nerve?

It is possible to remove the nerve under the crown, but it will require considerable effort on the part of the dentist. It will be necessary to remove dental crowns in order to heal teeth that have begun to hurt, and this is associated with the risk of losing the orthopedic structure. A crown may not always need to be reinstalled after removal. That is why they try to remove the pulp with the nerve even from a healthy tooth, and only then install crowns or bridges. Cavities under the crown can also develop if the tooth is not treated properly. Based on this, dentists try to immediately place the prepared tooth under a crown or cover its surface with a temporary structure in order to limit the contact of the enamel-less surface with food.

When a dental crown is placed on a pin or on an inlay, they try to protect the surface of the tooth with a temporary filling while the main structure is being manufactured. Making dental crowns sometimes takes several weeks if the clinic is small and the dental technician is constantly busy with work.

Metal ceramics or zirconium?

Many patients wonder: what is better – zirconium crowns or metal-ceramics? Roughly speaking, both structures are metal-ceramic, but zirconium is a so-called “white” metal that does not shine through ceramics, as happens with ordinary metal. Therefore, today ceramic crowns on a zirconium frame are close in aesthetic qualities to all-ceramic crowns, but at the same time they have the same strength as metal-ceramics. However, the prices for such prostheses are higher than for metal-ceramic structures.

Which teeth are crowns placed on during prosthetics?

Today, the question “which teeth are crowned on” refers less to their location on the upper or lower jaw, but to the condition of the teeth themselves. If you need to remove the defect of only one tooth, on which a crown is installed for this purpose, then its condition can be initially any. But before it comes to making a crown, the tooth requires basic treatment. If a patient develops processes such as periodontitis, then first the doctor must go through all the canals and seal them using gutta-percha pins and filling material. The quality of root filling should be checked using an x-ray. If a cyst is found near the roots, then this is not always a reason to remove the tooth, but it requires longer treatment, the prescription of antibiotics and other drugs that help restore damaged soft tissue.

If the visible part of the tooth is completely destroyed, then the crown can be installed on the root using a dental inlay. If it comes down to tooth extraction, and the person agrees to implantation, then in this case, too, a crown is used, which “crowns” the implant, imitating the visible part of the tooth. But where to put the crowns, on the upper and lower teeth, it doesn’t matter. Even if it is necessary to properly heal wisdom teeth that a person chews normally, dental crowns can be installed.
