In dentistry, the word “filling” actually refers to the material used to fill cavities resulting from the removal of dental tissue affected by cavities. For various reasons, it can happen that the filling “falls” by itself.

The loss of a filling, whether total or partial, is sometimes unpleasant, but it may also be overlooked. However, there are some signs that may attract our attention:

• A slight pain or sensitivity may be felt in the tooth;
• There may be some discoloration of the tooth or even filling;
• The tongue may feel a crack in the filling or even its absence;
• A filling can become slightly mobile and no longer appear to be soldered to the tooth.

The causes of a fallen filling are very varied. The most frequently observed are:

• A very severe shock in the head area;
• A shock with a hard substance on a particular tooth (by crunching a fork or food that is too hard);
• Tooth grinding (bruxism);
• Clenching (clenching);
• A tooth decay;
• Poor occlusion of the teeth (poor distribution of forces between the teeth);
• Inadequate repair of a tooth (defective filling or wrong choice of material);
• Consumption of drinks or foods that are too hot or too cold, which can break the bonds of the filling.

While waiting for your dentist appointment:

• Rinse the mouth with warm water to avoid subjecting the exposed dentin to excessive temperature changes;
• Avoid eating hard foods. Choose foods that are easy to eat, such as yogurt or compotes;
• Take the precaution of eating on the side that is not affected by the loss of the filling;
• Avoid hot or cold drinks;
• Place a chewing gum where the old filling was. This will block the passage of air and reduce pain.

Even in the absence of pain, a dental appointment is necessary to avoid further infections.

Different solutions are possible:

• If the tooth is well preserved, a new filling will be made;
• If a cavity has already formed or if part of the tooth is fractured, a dental crown (CEREC or laboratory) may be considered;
• If the pulp is affected, a root canal treatment will be performed, followed by a crown.

Over time, a filling can weaken and gaps can be created between the filling and the tooth, leaving the possibility for bacteria to infiltrate. This can lead to the formation of a cavity under the filling. If left untreated, this cavity will continue to progress inward and may reach the pulp or form an abscess.

As indicated above, a filling, especially a recent filling, so not necessarily completely hardened, must be preserved by a few precautions:

• Avoid eating or drinking hot substances;
• Eat soft foods such as yogurt or compotes;
• Do not chew on the side where the new amalgam is placed;
• Check that you do not feel any bumps and that you are satisfied with the occlusion. If not, go back to your dentist who will adjust your amalgam;
• Maintain good oral hygiene practices at all times, including brushing, flossing and, if necessary, interdental brushes, 2 to 3 times a day. Also make an appointment once or twice a year with your dentist for cleaning (prophylaxis) and a complete dental examination.
