The short answer

What is a filling?

A filling repairs a tooth that has been damaged by decay. The decayed part of the tooth is removed and the space is filled with a material that restores the tooth’s shape and function.

Placing fillings is part of a dental therapist’s scope of practice set by the General Dental Council, for both adult and children’s teeth. At Bilton Road Dental Practice, your filling is planned following an examination, and I’ll explain whether you need to see the dentist first.

Repairing the tooth is only half of the job. We’ll also look at why the decay happened, from diet to brushing to fluoride, so the same tooth, or the next one, is less likely to need treatment.

Signs of decay

How tooth decay shows itself, and what fixes it.

Decay often causes no symptoms at first, which is why it’s usually found at a check-up. These are the signs to look out for.

Signs to look out for

  • Toothache
  • Pain when eating or drinking something hot, cold or sweet
  • White, brown or black marks on a tooth
  • A hole (cavity) in a tooth

See a dentist as soon as possible if you think you or your child has tooth decay.

What fixes it, as decay progresses

  1. Early decayFluoride varnish or mouthwash can help reverse it
  2. A cavityA filling repairs the tooth
  3. Decay reaches the nerveRoot canal treatment may be needed
  4. Severe decayThe tooth may need to be removed

Your appointment

What happens during a filling. Numb first, then repair.

Once the tooth is numb, the decay is removed and the tooth is repaired and polished. You’re told what’s happening at each stage.

Ask about fillings

From the chair

What patients ask me before a filling.

Fillings are one of the most common dental treatments, and it’s still completely normal to feel uneasy about having one.

“Will I feel the injection?”

Most people feel a brief pinch and then the area goes numb. I go slowly, explain each step before I start it, and you can ask me to pause at any time. If you’re nervous, tell me when you book and we’ll allow more time.

“The tooth doesn’t hurt. Does it really need a filling?”

Decay often doesn’t hurt until it’s quite deep, which is why treating it earlier is usually simpler. I’ll show you what I can see and explain why it needs repairing, and you’re always free to ask questions before deciding.

“Why do I keep needing fillings?”

That’s the question that matters most, and it usually comes down to a few things: how often sugar is in the mouth, how plaque is cleaned away, and fluoride. We’ll look at all three, so the cycle stops.

Honest expectations

What a filling can, and can’t, do.

A filling is a reliable repair, but it works best as part of a plan to prevent further decay.

It can

  • Repair a tooth damaged by decay and restore its shape
  • Stop decay in that area from getting worse
  • Reduce sensitivity caused by a cavity
  • Help you chew comfortably again

It can’t

  • Prevent decay in other teeth on its own
  • Last forever: fillings can wear and may need replacing over time
  • Fix a tooth that needs a crown, root canal treatment or extraction, which the dentist provides
  • Replace good brushing, less frequent sugar and fluoride

Does a filling hurt?

The tooth is numbed with local anaesthetic, so you should feel pressure and vibration rather than pain.

The numbness wears off over a few hours. The tooth may be a little sensitive to hot and cold for a short time afterwards.

Aftercare that keeps the result

  • Wait until the numbness wears off before eating or hot drinks, so you don’t bite your lip or cheek
  • Expect a little sensitivity to hot and cold for a few days
  • Keep sugary food and drinks to mealtimes
  • Tell me if your bite feels high or the sensitivity doesn’t settle

How long do fillings last?

  1. Many yearswith good care, though they can wear over time
  2. Checked at every visitso any problems are found early

Regular check-ups, at intervals based on your own risk, help spot worn fillings and new decay early.
