Step-by-Step Dental Filling Procedure
A dental filling procedure follows five steps: examination, numbing, cavity cleaning, filling placement, and a bite check. Each step builds on the last, and your dentist explains what’s happening as you go.
Examination and Diagnosis
Your dentist starts by examining the tooth for decay and checking how far it has spread. A dental probe or a caries-detecting solution helps pinpoint the affected area, and an X-ray shows what’s happening below the surface. For a closer look, CBCT imaging is available at every branch and gives your dentist a detailed 3D view of the tooth and surrounding bone.
Based on these findings, your dentist decides whether a filling is the right treatment or whether the tooth needs something else, like a crown or root canal. The size, depth, and location of the decay all factor into that decision.
Numbing the Area
Local anaesthetic numbs the tooth and surrounding gum before any drilling starts. A topical numbing gel goes on first, so the injection itself is more comfortable. For patients who feel anxious about the appointment, nitrous oxide sedation is available at Casa Dental, a mild, inhaled sedative that helps you relax while staying conscious throughout.
Tell your dentist if you’re nervous about the appointment. They can adjust the pace or add more numbing gel if you need it.
Cleaning the Cavity
The dentist removes decayed tooth structure using a dental drill or air abrasion tool, clearing the decay while preserving as much healthy tooth as possible. The tooth is kept dry and isolated with a dental dam or cotton rolls, so saliva can’t interfere with the filling material.
Once the decay is out, the dentist cleans and disinfects the cavity. For composite fillings, the cavity walls are etched to help the material bond, and the area is kept dry before the next step.
Placing and Shaping the Filling
The dentist places the chosen filling material into the cavity in layers, shaping each one to match the tooth’s natural contours. Composite fillings are hardened with a curing light as they’re built up, while amalgam and gold fillings are packed in and shaped by hand.
For ceramic fillings, an in-house lab with CAD/CAM milling equipment lets your dentist produce a well-fitted restoration on site. Once the filling is in place, the dentist trims and polishes any excess material.
Final Bite Check
The dentist checks your bite once the filling is in place, asking you to bite down so the tooth feels even against the ones around it. Any high spots are adjusted on the spot with fine polishing tools.
If your bite still feels uneven after the anaesthetic wears off, can a tooth filling cause bite imbalance covers what’s normal and when it’s worth a follow-up visit.
Mild sensitivity to hot, cold, or pressure after a dental filling procedure is common and usually settles within a few days. Tooth sensitivity after a filling explains when that’s normal and when it’s worth a call to your dentist.
Soft foods and gentle chewing on the filled side help the material set properly on the first day. What to do after dental fillings covers full aftercare, from diet to oral hygiene.
How Long Does a Dental Filling Procedure Take?
A dental filling procedure is completed within a single appointment for most patients. The exact time depends on how many teeth need treatment, the size of the cavity, and the filling material your dentist selects, so your dentist gives you a clearer estimate once the tooth has been examined.
Filling Materials at a Glance
Four filling materials cover most cavities: composite resin, amalgam, gold, and ceramic. Composite resin is tooth-coloured and often used on front teeth. Amalgam is a durable, silver-coloured material often used on back teeth that take more chewing pressure.
Gold fillings last a long time but are more visible than tooth-coloured options. Ceramic fillings match the colour of natural enamel and can be milled in-house for a precise fit.
Types of dental fillings and which one is best for your specific tooth depends on its location, size, and how much chewing force it takes, and your dentist walks through the trade-offs at consultation.
What to Do Next
A dental filling procedure is one of the most routine treatments in general dentistry, and treating a cavity early keeps the procedure simple. Waiting tends to let the decay spread, which can turn a straightforward filling into a more involved treatment.
Tooth filling cost in Singapore depends on the material and number of teeth involved, and your dentist gives you a clear figure at consultation before any work begins.

Frequently Asked Questions
Do fillings hurt?
A dental filling procedure does not hurt once the anaesthetic takes effect. You may feel pressure or vibration while the dentist works, but not sharp pain. Tell your dentist right away if you feel any discomfort, they can add more anaesthetic.
Do you need anesthesia for a filling?
Most dental filling procedures use local anaesthetic to numb the tooth before any drilling starts. Your dentist may also offer a topical gel or nitrous oxide sedation if you feel anxious about the injection. Small or shallow fillings sometimes need less numbing, your dentist decides at the appointment.
Can a filling be replaced?
A dental filling replacement procedure is routine when a filling wears down, cracks, or decay forms around its edges. Your dentist checks the condition of existing fillings at routine visits and replaces one if it’s compromised.
What's a dental filling procedure like for a child?
A children’s dental filling procedure follows the same basic steps as an adult’s, with a gentler pace and a shorter appointment where possible. Your dentist adjusts communication and timing for younger patients.
