Caring for St. Williams patients at our office in Port Dover
Every dental service for St. WilliamsTime for an update?
Not every old filling needs replacing, but some do.
Fillings do not last forever. Over years of chewing, they can wear, crack, stain or develop gaps at the edges where decay can start. Some people also want to replace old dark fillings with tooth-coloured material for appearance. Deciding whether to replace a filling involves weighing its condition, the health of the tooth and your personal goals.
St. Williams residents with fillings they are unsure about can have them assessed at our Port Dover office. The dentist will explain which fillings are sound, which are showing signs of failure and what replacement options make sense for each tooth.
Assessing fillings
Look at function, not just appearance.
When a filling may be failing
Cracks in the filling or tooth, gaps at the edges, decay underneath, rough or broken surfaces and sensitivity can indicate that a filling needs replacing. X-rays help detect decay beneath fillings that cannot be seen directly. Food catching around a filling may also suggest a problem.
When a filling is still sound
A filling that is intact, sealed and free of decay may not need replacing, even if it is old or a different colour from the tooth. Removing a sound filling always takes away some tooth structure. The dentist will explain the condition of each filling and whether replacement is necessary.
Cosmetic reasons
Appearance can be a valid reason to replace.
Replacing dark or stained fillings
Silver amalgam fillings may show when you smile or laugh, and older tooth-coloured fillings can stain over time. Replacing them with modern tooth-coloured materials can make the smile look more natural. This is a personal choice, and the dentist can help you understand the options.
Weighing the trade-offs
Each time a filling is replaced, the cavity tends to get slightly larger, and the tooth may eventually need a crown. Replacing sound fillings purely for appearance should be considered carefully. Ask the dentist about the long-term implications for each tooth before deciding.
Replacement options
The right material depends on the tooth.
Composite fillings
Composite resin is commonly used to replace old fillings, matching the shade of natural teeth and bonding to the tooth. It suits small to moderate fillings. For front teeth and visible areas, composite can offer a good cosmetic result when the tooth has enough healthy structure.
Inlays, onlays and crowns
If an old filling was large or the tooth is weakened, an inlay, onlay or crown may be recommended to protect it. These are made in a laboratory and can be more durable for heavily restored teeth. The dentist will explain which option is best for each tooth.
Treatment and care
Replacement is similar to placing a new filling.
Removing and replacing
The tooth is numbed, the old filling and any decay are removed and the tooth is prepared for the new restoration. Composite is placed and shaped, or impressions are taken for a laboratory restoration. The bite is checked and adjusted. Several fillings may be replaced in one visit or spread over several.
Looking after new fillings
Some sensitivity after replacement is common and usually settles. Brush and floss carefully around the new fillings and limit sugary snacks. Regular checkups allow the dentist to monitor the restorations and catch any problems early.

Filling replacement questions
Have a question about your situation? Our team can help you plan a visit.
Should I replace all my silver fillings?
Not necessarily. Sound fillings without decay or damage may not need replacing. The dentist will assess each one and explain whether replacement is recommended or optional.
Are silver fillings unsafe?
Health organizations generally consider amalgam fillings safe for most people. If you have concerns, discuss them with the dentist, who can explain current guidance and options.
How long do replacement fillings last?
It depends on the material, size, location and your habits. Composite fillings may last many years with good care. Regular checkups help monitor their condition.
Will replacing a filling hurt?
The tooth is numbed during the procedure. Some sensitivity afterward is normal and usually settles. Let the dentist know if discomfort persists.
Can stained tooth-coloured fillings be polished?
Surface staining can sometimes be improved by polishing. Deeper discolouration may need replacement. The dentist can assess which approach suits each filling.
