Caring for St. Williams patients at our office in Port Dover
Every dental service for St. WilliamsRepair that blends in
Restore the tooth after decay is removed.
Composite fillings are made from a tooth-coloured resin that bonds to the tooth surface. After the dentist removes decay or damaged structure, the material is placed in layers, shaped and hardened with a curing light. They are commonly used for small to moderate cavities and for chipped areas where appearance matters.
St. Williams patients can have a cavity assessed and filled at our Port Dover office. The dentist will explain why a filling is recommended, how large it is likely to be and whether composite is the right material for that particular tooth before beginning.
Is a filling needed?
Not every dark spot or twinge means a cavity.
Signs of a cavity
Sensitivity to sweets or cold, food catching in one spot, a rough edge or a visible hole can all signal decay. Early cavities often cause no symptoms at all and are found during routine checkups. Staining on the surface of a tooth may look similar to decay but does not always need treatment.
Confirming with an exam
The dentist will examine the tooth and may take X-rays to look between teeth or check how deep the decay goes. If the problem is very small, monitoring and fluoride might be suggested instead of drilling. Ask how the dentist reached the recommendation and what happens if treatment is delayed.
Material choice
Composite suits many, but not all, situations.
Where composite works well
Composite is a good choice for front teeth and many back teeth because it can match the natural shade. It bonds to the tooth, which may allow a more conservative preparation in some cases. It is commonly used for small to medium cavities where enough healthy tooth remains to support the filling.
When another option fits better
Very large cavities, teeth with cracks or areas under heavy biting pressure might do better with an onlay or crown. The dentist will consider how much tooth remains, your bite and any grinding habits. If a filling is likely to be at the limit of what composite can support, ask about the alternatives.
The procedure
Most fillings are completed in one visit.
Numbing and preparing the tooth
Local anaesthetic is usually used to keep the tooth comfortable. The dentist removes decay and prepares the surface so the material can bond. The tooth is kept dry during placement, sometimes with a small rubber sheet. Let the team know if you need a break or feel any discomfort.
Layering, shaping and polishing
Composite is placed in layers and hardened with a special light. The dentist shapes the filling to match the tooth’s natural contours and checks your bite with marking paper. Final polishing smooths the surface. You can usually return to normal activities right away, though numbness may last a few hours.
Aftercare
A little attention keeps the tooth healthy.
What is normal afterwards
Avoid chewing on the numb side until feeling returns to prevent biting your cheek or tongue. Mild sensitivity to cold or pressure for a short time is common. If the bite feels high, or pain grows instead of fading, call the office so the filling can be checked and adjusted.
Helping the filling last
Brush twice a day, clean between teeth and limit frequent sugary snacks to reduce the chance of new decay around the filling. Composite can stain over time with coffee, tea or tobacco. Regular checkups allow the dentist to monitor edges and spot any breakdown early.

Composite filling questions
Have a question about your situation? Our team can help you plan a visit.
How long do composite fillings last?
Longevity varies with the size of the filling, your bite, grinding habits and home care. Many last for years. Regular checkups allow the dentist to spot wear, staining or leaks around the edges before larger problems develop.
Does getting a filling hurt?
Local anaesthetic is normally used so the procedure is comfortable. You may feel pressure or vibration. Some sensitivity afterward is common and usually settles. Tell the team if you are anxious so they can explain each step.
Can I eat right after a composite filling?
Composite hardens during the appointment, so eating is possible once numbness wears off. Wait until feeling returns to avoid biting your lip or cheek. Start with softer foods if the tooth feels tender.
Can an old metal filling be replaced with composite?
Sometimes. The dentist will assess whether the old filling is failing and whether composite is suitable for that tooth. Replacing a sound filling purely for appearance is a decision to discuss carefully.
Why does my new filling feel sensitive to cold?
Short-term sensitivity is common, especially after deeper fillings. If it lasts more than a few weeks, worsens or becomes spontaneous pain, contact the office for an assessment.
