Caring for Renton patients at our Port Dover office
See every dental service for RentonTooth-coloured repairs
A composite filling restores a decayed tooth while blending with its natural shade.
Composite resin is a tooth-coloured material that bonds to enamel and dentin. It is commonly used to repair cavities, replace small worn fillings and rebuild minor chips. Because it is placed in layers and hardened with a curing light, the dentist can shape it to match the contours of the tooth.
For anyone in Renton with a cavity diagnosed or suspected, the work is done at our Port Dover office. The dentist will explain whether composite is suitable for that particular tooth, what the appointment involves and how long you might expect the filling to serve you with good care.
Spotting a cavity
Cavities often start quietly and become noticeable later.
Symptoms you might notice
Early decay usually causes no symptoms. As it grows, you might notice sensitivity to sweets, cold or hot drinks, food catching in one spot, a rough edge or a dark area on a tooth. Pain when biting can also be a sign. Any of these is worth mentioning at a checkup or calling about sooner if they worsen.
What an exam can show
During an examination, the dentist looks and feels for soft or discoloured areas and may use X-rays to find decay between teeth or under old fillings. Not every mark is a cavity. Some early changes can be watched or treated with fluoride. The dentist will explain what was found and why a filling is or is not recommended.
Why composite
Material choice depends on the size and location of the cavity.
Where composite works well
Composite is often a good choice for small to medium cavities, front teeth and visible areas where appearance matters. Bonding to the tooth can allow a more conservative preparation in some cases. It is also used for repairing chipped edges and closing small gaps when the tooth is otherwise healthy. It can also be repaired fairly easily if it chips.
When another option may be suggested
Very large cavities, teeth under heavy biting force or areas that are hard to keep dry may be better served by an inlay, onlay or crown. People who grind heavily may see faster wear. The dentist will discuss these factors so you can understand why a particular restoration is being proposed for that tooth. Ask about every option.
The appointment
Most composite fillings are completed in a single visit.
Numbing and removing decay
The dentist usually numbs the area with local anaesthetic, then removes the decayed portion of the tooth. The tooth is isolated to keep it dry, which is important for bonding. If the cavity is deep, a protective layer may be placed first. You can signal for a break at any point during the procedure by raising a hand.
Layering, curing and polishing
Composite is applied in thin layers, each hardened with a blue curing light. The dentist shapes the filling to fit your bite, checks it with marking paper and polishes it smooth. Afterward your lip and cheek may stay numb for a few hours, so be careful with hot drinks and avoid chewing until feeling returns.
Looking after it
Good habits help protect both the filling and the tooth around it.
Normal settling
Mild sensitivity to cold or pressure is fairly common for a short time after a filling. If the bite feels high, if pain increases or if sensitivity lasts beyond a few weeks, call the office. A small adjustment is often all that is needed, but the dentist should check to rule out other issues with the tooth.
Making the filling last
Brush twice daily with fluoride toothpaste and clean between teeth every day, since decay can form again at the edges of a filling. Limit frequent sugary snacks and drinks. Avoid chewing ice or hard objects. Regular checkups allow the dentist to monitor the filling and catch wear or staining before it becomes a real problem.

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 size, location, bite forces and home care. Many last for years, though they can wear, stain or chip over time. Regular checkups let the dentist assess when a filling might need repair or replacement.
Will the filling match my teeth?
Composite is selected to blend with the surrounding tooth. The match is usually close, though it may change slightly as natural teeth age or stain. Talk to the dentist if appearance is a priority for a front tooth.
Does getting a filling hurt?
The area is usually numbed, so most people feel pressure rather than pain. Some sensitivity afterward is common and tends to settle. Let the dentist know during the procedure if you feel discomfort at any point.
Can I eat right after a composite filling?
Composite is hardened during the appointment, but if you were numbed, wait until feeling returns to avoid biting your lip or cheek. Start with softer foods if the tooth feels tender for a day or so.
Can old metal fillings be replaced with composite?
Sometimes, when there is a clinical reason or the patient prefers a tooth-coloured option. Replacing a sound filling removes some tooth structure, so the dentist will discuss whether it is advisable for your teeth and goals.
