Dental Fillings: Types and What to Expect

A dental filling repairs a tooth damaged by decay, restoring its shape and function and stopping further deterioration. Here are the common types and what to expect at your visit.

Types of filling

Type Looks Good to know
Composite (tooth-coloured) Matches the tooth Bonds to the tooth; popular for visible teeth
Amalgam (silver) Metallic Hard-wearing; used on back teeth
Ceramic Tooth-coloured Stain-resistant and durable
Gold Gold Long-lasting; less common today

Your dentist will suggest a material based on the size and position of the cavity, your bite, and your preference.

Why fillings matter

A cavity is a small hole that only gets bigger if left alone, causing pain, infection, or tooth loss. A filling seals the cavity, restores the tooth's strength so you can chew comfortably, and stops bacteria reaching deeper into the tooth.

What to expect at your visit

  1. Numbing — the area is numbed with local anaesthetic if needed.
  2. Removing decay — the dentist clears the decayed part of the tooth and cleans the cavity.
  3. Filling — the material is placed, shaped, and (for composite) set with a curing light.
  4. Finishing — the filling is trimmed and polished, and your bite is checked. The visit usually takes under an hour.

Mild sensitivity for a day or two afterwards is normal. Cavities are among the most common health conditions worldwide, which is why regular check-ups matter — they catch decay while a simple filling is still all that's needed.

If a tooth is sensitive or you've spotted a hole or dark spot, book a fillings appointment and we'll restore it before it grows.
