Dental fillings

A dental filling is a method of filling a cavity that has formed after a cavity has been removed. In order to restore the tooth, the root of the tooth to be filled is always intact, and only the decayed parts are cleaned. This treatment is effective not only for decayed teeth, but also for broken and deformed teeth.


Bacteria in the mouth, which are produced from food residues, contain acid, which creates cavities on the surface of the teeth over time. If the tooth is not cared for at the appropriate time, the decay will enter the nerves and become very painful. As a result, it is important to maintain good oral hygiene on a regular basis in order to avoid cavities.

Tooth filling is a painless procedure that typically includes a local anesthetic. A mild irritation in the teeth may occur in the first few hours of treatment, but this is common. Patients are commonly able to eat and drink normally after surgery.

Depulpation of a tooth necessitates the use of specialized instruments and protocols, including examination, anesthesia, separation, access cavity, forming, and disinfection of the root canals. The final stage of the pulpectomy is to permanently close the canals to avoid bacterial penetration and to achieve a stable periapedia.

Endodontic obturation aims to produce a three-dimensional and durable filling of the root canal system with one or more biocompatible materials in order to ensure watertightness and periapical healing. Obturation should only be done if the health criteria warrant it and if certain requirements are met:


  • asymptomatic tooth when percussion is applied;
  • periapedia without edema and palpation sensitivity;
  • no oozing in the canal;
  • fistula closing at the intersession;
  • lack of odor;
  • Maintaining the temporary coronal restoration’s water tightness during the intercession.

The obturation will require the combined use of points or cones and cement. The injection of cement alone into the canals is not satisfactory because it is difficult to control and not very dense.


And if the cone seems to be well adapted, insertion of a cementless cone into the canal is not watertight. As a result, some methods for optimizing the mixture of cones and cement have been suggested.

Fillings come in a variety of shapes and sizes.

  • The most popular forms are as follows:
  • Dental composite fillings
  • Filling with amalgam

Filling of amalgam: It is made up of many metals and has a long life cycle. However, due to their dark look, amalgam fillings are no longer aesthetically appealing and are less common than they once were.

Composite dental fillings are more common today because they are more similar to the natural color of the teeth. They have a good cosmetic quality, and until you look carefully, you can’t tell the difference between them and actual teeth.

Aside from composites and amalgams, the following varieties of dental fillings are often used:

  • Fillings made of porcelain
  • Fillings made of gold
  • Filling of glass ionomer

How long can a dental filling last?

Dental fillings, in general, last for several years. However, its lifespan is, of course, determined by sound patterns of use and regular dental treatment. As a result, the period can be more than ten years or less.

Amalgam fillings are the most long-lasting form of dental filling.


Dental fillings:

The use of as little metal as possible is one of the key objectives of dental aesthetics. This is how plastic and porcelain fillings first emerged. Although older amalgam fillings were manually repaired, modern materials have a chemical makeup. This ensures that the fillings adhere to the teeth using a chemical bond, resulting in a stronger and more durable bond.

The tooth and its surroundings are totally indifferent after anaesthesia, so the procedure is painless. After cleaning the decay, the dentist uses a special glue to prepare the tooth’s surface. This substance can help to hold the filling in place in the dental cavity. The filling of the desired color will be applied in layers to the cavity, and the dentist will shape the corners and grooves to match the tooth’s appearance. A special lamp is used for chemical fixation, which emits a blue light that attracts the chemical materials found in modern plumbing and causes the chemical bond to form. The end result is a natural looking dentin hard filling.

A missing or badly decayed tooth needs to be restored there are some methods that can be used that involves the use of amalgam, composite, or onlay materials.


It’s made up of a combination of silver powder and mercury. This paste is added after the tooth has been devitalized.

Amalgams have a long shelf life (20 to 30 years depending on the case).

They allow the filling of significant cavities and the restoration of damaged teeth, as long as the loss of material is not excessive. Furthermore, they have a lead colour although they do not contain any. We used to refer to it as “filling” because of its hue. This form of technique is being phased out due to the mercury it contains.

The composite:

It’s a ceramic and synthetic-resin composite that’s 75% ceramic and 25% synthetic resin.

Its benefits include being aesthetically pleasing because it matches the colour of the teeth and not containing mercury. It is completed in a single sitting. However, a distance between the tooth and the composite may develop over time, causing the composite to fail. This is why we are favouring onlay more and more.

Chipped teeth or thin, minimally invasive cavities may also be repaired with composite.

The onlay:

It’s a custom crown that’s glued to the tooth. Much of the time, we clean the cavities carefully under local anaesthesia. Then we take an impression of the tooth that has been affected. A composite or ceramic crown is then created by the dental technician and glued to the damaged tooth by the dentist.
