What is a Dental Filling?

A dental filling is a restorative procedure done to reconstruct the tooth structure lost due to dental caries or fractures. Dental fillings are advised only when caries or damage is confined to enamel or dentin. When a tooth is infected with dental caries, the infected tissue is removed by preparing a cavity and restored with a suitable dental filling material. Dental fillings are also used to repair fractured teeth. Dental fillings are recommended to restore tooth structures that are lost due to physiological or pathological wear.

Dental Fillings

  • Dental caries- a bacterial infection of dental hard tissue.
  • Fractured teeth- due to trauma
  • Attritions- Attrition is physiological wearing due to chewing or bruxism.
  • Abfractions- are micro-fractures of enamel that occur due to abnormal forces on the tooth.
  • Abrasion- due to abnormal brushing habits, ditch-shaped defect in enamel, and dentin.
  • Diastema closure- gaps between teeth

  • Restore lost tooth structure.
  • Prevent progression of dental caries.
  • Restore aesthetics and confidence.
  • Provide strength to the teeth.
  • Restore normal function and speech.

If the dental filling is not done for a decayed tooth at the correct time, the infection progresses from enamel to dentin. If caries are confined to dentin, pulpal inflammation is reversible. Further delay in treatment causes microbes and their products to reach the pulp and results in irreversible pulpitis. At this stage, the tooth would require expensive and extensive root canal treatment.

  • Like every other dental treatment, the first step is to check the extent and severity of the condition, as dental filling treatment is appropriate only for minor decays and cracks. The X-ray would be done if required.
  • Local anesthesia may be administered to minimize the discomfort during cavity preparation.
  • The decayed portion of the tooth is removed by using dental burs and the appropriate cavity is designed to retain the restoration in the cavity.
  • If needed, a laser can be used to remove the damaged part.
  • In the case of a deep cavity, application of pulp protection agents may be required, after which the area is filled with a dental filling.
  • The type of material used for filling varies according to the clinical scenario and keeping in mind the patient’s requirements.

  • Avoid chewing hard food on the restoration site for the next 8 hours after dental filling.
  • Avoid chewing sticky food and chewing gums.
  • Avoid taking hot and cold food for few days.
  • A patient may experience mild sensitivity for the next few days.
  • Maintain good oral hygiene.

Why Choose Us ?


Usually, 8 hours following dental filling, the patient can chew on the side of restoration.

Composite dental fillings may sometimes allow repair without replacement.

No. Dentin sensitivity following dental fillings subside after a few days. If not, consultation with a dentist is required.

The longevity of dental restoration depends on the type of filling, habits of the patient, and clinician’s skills. Usually, amalgam restorations last for 10-15 years, whereas composite restorations last for five years.
