Start with what matters to you.
I can see a dark filling when I laugh.
Ask whether it needs replacing. Removing a sound filling solely for colour has trade-offs.
Food keeps catching in one place.
Describe where it happens so the dentist can check the tooth and contact with its neighbour.
I worry the hole is too big.
Ask whether the remaining tooth needs an onlay or crown instead.
Understanding Composite Filling.
A Composite Filling repairs a damaged area using tooth-coloured resin (a mouldable material). It can be used in front or back teeth, but the size of the cavity and remaining tooth affect whether a filling is the right option.
The cavity, the bond and the bite.
Resin & Filler
Composite combines resin with fine glass or ceramic particles to make a tooth-coloured material.
Adhesive Bond
The prepared area is bonded and the resin is set, usually with a curing light.
Contact & Surface
The filling is shaped to meet the next tooth and your bite, then finished.
What Happens During Treatment.
Your dentist confirms the stages and timing for your own treatment plan.
Examine the Tooth
The dentist checks the damaged area and may take an X-ray. A large or deep defect may need a different repair.
Numb and Clean the Area
Local anaesthetic is used when needed. Decay or damaged filling material is removed and the area prepared.
Place the Filling
The chosen material rebuilds the missing area. Tooth-coloured composite is shaped and hardened with a special light.
Check Your Bite
The dentist smooths the filling and checks your bite. Follow their eating advice and report persistent sensitivity or a high spot.
The exact appointments and recovery time depend on your assessment and the treatment agreed with your dentist.
Your Options with This Treatment.
Things to Consider.
Some sensitivity can occur, but persistent pain, swelling or a bite that feels too high needs advice from the practice. A deep cavity may need further treatment even after a filling.
Your Composite Filling questions.
Will the filling match my tooth?
The dentist selects a tooth-coloured shade; discuss expectations for a visible repair.
How long will it last?
There is no fixed lifespan. Size, bite and care affect future repair needs.
Is replacing every silver filling necessary?
No. Ask for the reason to replace each one, rather than choosing by colour alone.
