Dental Fillings: The Procedure, Step by Step

How much healthy tooth is preserved during preparation matters more to the long-term outcome than the filling material itself. This page covers the dental fillings appointment itself — what is prepared beforehand, what happens in the chair, and what the first hours afterwards feel like. Plan for 1 appointment and 1-2 days.

Quick answer

A single filling takes 20-40 minutes; a molar root canal typically needs 60-90 minutes and is sometimes split across two visits. Local anaesthetic, usually a single infiltration or a block for lower molars. Paediatric cases often use topical gel plus behavioural technique before any needle. How much healthy tooth is preserved during preparation matters more to the long-term outcome than the filling material itself.

Before your procedure

What's confirmed before you're in the chair.

  • A periapical X-ray of the tooth in question, and a pulp sensibility test where the diagnosis is uncertain
  • Confirmation that rubber dam isolation will be used, which is standard of care for both bonding and endodontics
  • A decision recorded on material choice: composite, ceramic inlay or a full-coverage crown afterwards
  • For children, an appointment early in the day and a clear explanation of what happens before the visit
  • A written, fixed price covering 1 appointment — confirmed before you fly, not on arrival
Step by step

What happens during dental fillings.

  • Stop 01

    Records check on arrival

    Your scan or photographs are reviewed in person against the remote plan. How much healthy tooth is preserved during preparation matters more to the long-term outcome than the filling material itself.

  • Stop 02

    Isolation

    Rubber dam is placed. Saliva contamination is the most common cause of a bond failing or a canal becoming reinfected.

  • Stop 03

    Removal of diseased tissue

    Decay or infected pulp tissue is removed under magnification, with the extent verified rather than estimated.

  • Stop 04

    Sealing and restoration

    Canals are obturated or the cavity is built up in increments and cured, then the bite is checked with articulating paper before you leave.

  • Stop 05

    What is specific to this option

    Tooth-coloured composite fillings to treat cavities and minor chips.

  • Stop 06

    Debrief and follow-up

    You leave with written aftercare and the follow-up schedule fixed — for this option that means 1-2 days, with 1 appointment in total.

Anaesthesia & duration

Local anaesthetic, usually a single infiltration or a block for lower molars. Paediatric cases often use topical gel plus behavioural technique before any needle.

A single filling takes 20-40 minutes; a molar root canal typically needs 60-90 minutes and is sometimes split across two visits.

Who performs it

A general dentist for routine restorations, an endodontist for retreatment or complex canal anatomy, a paediatric specialist for children. Ask whether rubber dam and magnification are standard practice.

Right after the procedure

The lip stays numb for two to four hours — the main practical risk is biting your cheek before sensation returns. A treated tooth may feel tender to bite on for a couple of days.

FAQ

Procedure questions, answered

How do I know if a filling is enough?

If the decay has not reached the nerve and enough wall structure remains. An X-ray answers this, a photo does not.

Do white fillings last as long as amalgam?

Modern composites are close, and they preserve more tooth during preparation.

Was rubber dam used?

It should have been. Isolation is directly correlated with the long-term survival of both bonded restorations and root canal treatments.

Will this tooth need a crown afterwards?

Root-treated molars usually do, because the remaining tooth structure is brittle. Ask whether that cost is inside or outside the quote.

How much natural tooth is left?

The answer determines whether a filling is a durable solution or a temporary one before a cusp fractures.

How many visits does dental fillings need in total?

1 appointment — and 1-2 days. Any quote that compresses that materially is worth a second read, because laboratory and healing time set the schedule, not the clinic diary.

How does this compare with the closest alternative?

Root canal treatment is needed once the nerve is involved; crowns take over when too little tooth remains.

Recognise the signs

Signs it might be time to look into this.

01

A tooth is sensitive to sweet or cold

Short-lived sensitivity often indicates early decay.

02

You can feel a rough edge or hole

Cavitation you can feel is already past the earliest stage.

03

An old filling has cracked or dropped out

Marginal breakdown lets decay restart underneath.
