How long does a typical tooth filling procedure last?

A straightforward filling may take around 20–60 minutes, but appointment times vary. The time depends on:

• Cavity size. A small cavity is quicker to repair than a large one.
• Location. Back teeth are harder to reach than front teeth.
• Number of teeth. Filling several teeth takes longer.
• Complexity. Deep decay or an X-ray first can add time.

Sometimes. A small, simple filling may be finished in about half an hour, but this cannot be promised before the dentist has examined the tooth. Your dentist gives you an idea of the time once they have seen the cavity.

The tooth is usually numbed with a local anaesthetic first. Most people then feel pressure or vibration rather than sharp pain, although everyone experiences treatment differently. Tell the dentist straight away if anything feels uncomfortable.

• Examination. The dentist checks the tooth and confirms a filling is right for it.
• Removing decay. Decayed or damaged material is gently cleaned away.
• Preparation. The tooth is shaped and kept dry.
• Placing the filling. The material is added and, for white fillings, hardened with a curing light.
• Bite check. The filling is shaped and polished so your bite feels natural.

It depends on the filling material, whether you had an anaesthetic and what your dentist advises. White fillings are set hard before you leave.

Avoid chewing while your mouth is numb, because you could bite your lip, cheek or tongue without noticing. Read our guides on whether you can eat right after getting a filling and how long fillings last.
