Temporary & Permanent Fillings

Sussex Emergency dentist can offer immediate assessment and fitting of temporary and permanent fillings

Dental fillings are used to restore the function and integrity of a tooth that has been damaged by decay or fracture. Depending on the situation and the material used, fillings can be temporary or permanent. Here’s a detailed comparison of both types:

A temporary filling, also known as a provisional or interim filling, is used to protect a tooth temporarily while waiting for a more permanent restoration. Temporary fillings are designed to last a few weeks to a few months. They are not as durable as permanent fillings and should be replaced with a permanent restoration as soon as possible to ensure long-term protection of the tooth.

A permanent filling is a restorative dental procedure used to repair teeth affected by decay, cracks, or fractures. Unlike temporary fillings, permanent fillings are designed to last for many years and provide long-term protection and functionality to the damaged tooth.

Procedure for Placing a Temporary Filling:

  1. Anaesthetic
    • Local anaesthetic may be used to numb the area if the procedure involves deep decay or is expected to be uncomfortable.
  2. Tooth Preparation
    • The dentist cleans out the decay or debris from the tooth.
  3. Filling Placement
    • The temporary filling material is placed into the cavity and shaped to fit the tooth.
  4. Setting
    • Depending on the material, the filling may be left to set on its own or might need light curing.
  5. Adjustment
    • The dentist ensures the filling is smooth and comfortable, making any necessary adjustments.

It’s crucial to follow up with your dentist to replace the temporary filling with a permanent one. Temporary fillings are not meant for long-term use and can lead to complications like further decay or infection if left in place too long.

Procedure for Placing a Permanent Filling

  1. Anaesthetic
    • Local anaesthetic is administered to numb the area around the affected tooth.
  2. Decay Removal
    • The dentist removes the decayed or damaged portion of the tooth using a dental drill or laser.
  3. Tooth Preparation
    • The cavity is cleaned and shaped to ensure the filling will fit properly.
  4. Filling Placement:
    • Amalgam: Mixed and packed into the cavity.
    • Composite Resin: Applied in layers, with each layer being hardened using a special light.
    • Ceramic/Gold: Typically require impressions of the tooth to be made for custom fitting and may involve a temporary filling while the permanent one is fabricated.
  5. Shaping and Polishing
    • The filling is shaped to fit the natural contours of the tooth and polished to smooth any rough edges.

Permanent fillings are essential for restoring the function and integrity of a tooth, preventing further decay, and maintaining overall oral health. Regular dental visits and good oral hygiene practices can help ensure the longevity of permanent fillings.
