Caring for Renton patients at our Port Dover office
See every dental service for RentonUpdating aging dental work
Replacing an old filling makes sense when it is failing or genuinely bothers you.
Fillings do not last forever. Over years of chewing, they can wear, chip, darken, leak at the edges or develop decay underneath. Some people also want older silver fillings or discoloured tooth-coloured fillings replaced for appearance. Each replacement removes a little more tooth, so the decision should weigh the benefits against preserving healthy structure.
At our Port Dover office, Renton patients can have older fillings evaluated during an exam. The dentist will explain which restorations are sound, which are showing signs of failure and what options exist for replacement, so you can decide whether, when and how to update them based on clear information.
Signs of wear
Not every old filling needs replacing.
Clinical reasons
Cracks in the filling or tooth, gaps at the edges where food or bacteria can enter, recurrent decay beneath the filling, broken pieces and persistent sensitivity are common clinical reasons for replacement. X-rays and a close exam help identify these problems. If a filling is intact and the tooth is healthy, the dentist may recommend leaving it in place for now.
Cosmetic reasons
Older composite fillings can stain or darken over time, and silver amalgam fillings are visible when you smile or laugh. Some people choose to replace them for appearance. The dentist will explain the trade-offs, including the removal of additional tooth structure, and whether a cosmetic replacement is likely to give the result you want overall.
Evaluation
The dentist looks at each filling individually.
Examining each restoration
Each filling is checked visually, with an instrument and on X-rays. The dentist looks for open margins, cracks, wear and signs of decay. Your bite is assessed to see whether the filling is under heavy forces. You may be asked about any sensitivity or discomfort in particular teeth, which can help pinpoint failing restorations more quickly.
Prioritizing replacements
If several fillings need attention, the dentist can help prioritize based on urgency, such as active decay or cracks, versus cosmetic preference. Spreading replacements over time may be sensible. For Renton patients, grouping work in fewer longer appointments might reduce trips, though this depends on what is comfortable and clinically appropriate for you. Ask about it.
Replacement options
The replacement depends on the size of the old filling.
Tooth-coloured fillings
Small to medium fillings are commonly replaced with composite resin, which can be matched to the surrounding tooth. The old material is removed, any decay is cleaned out and the new filling is bonded into place. The dentist will explain how long composite typically lasts and what factors affect its durability over time and use.
Inlays, onlays and crowns
When an old filling is very large or the tooth has cracks, an inlay, onlay or crown may provide more strength than a new direct filling. These require more than one visit but can better protect a weakened tooth. The dentist will explain why a larger restoration might be recommended for a particular tooth instead.
After replacement
Good care helps new fillings last.
Settling in
Some sensitivity to cold or pressure is common after a filling is replaced and usually settles within a few weeks. If the bite feels high or sensitivity worsens rather than improves, contact the office for a check. A small adjustment can often resolve the problem. Avoid chewing on the treated side while numb or tender.
Keeping restorations healthy
Brush twice daily with fluoride toothpaste and clean between teeth daily to prevent decay at the edges of new fillings. Limit frequent sugary snacks and drinks. Avoid chewing ice or hard objects, and wear a night guard if you grind. Regular checkups allow the dentist to monitor restorations and catch wear early, before it causes trouble.
Planning your appointment
Having old fillings checked from Renton.
Ask for a filling assessment when you book an exam at our Port Dover office by calling 519-583-2929. Mention whether your main concern is appearance, sensitivity or a filling you think may be broken.
If certain teeth are sensitive or a filling feels rough, note which ones so the dentist can focus attention on them.

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. Replacing a sound filling removes additional tooth structure. The dentist will assess each filling and recommend replacement when there is a clinical reason or when you prefer a cosmetic change and understand the trade-offs involved.
How do I know if a filling is failing?
Signs include sensitivity, a rough or broken edge, food catching around it, dark areas at the margins or pain when biting. Sometimes there are no symptoms, and problems are found on X-rays or during an exam by the dentist.
Is replacing a filling painful?
The area is usually numbed, so most people feel pressure rather than pain. Some sensitivity afterward is common and generally settles. Let the dentist know if discomfort persists so the tooth can be checked again.
Can stained composite fillings be polished instead of replaced?
Sometimes surface stains can be polished away. Deeper discolouration or staining at the edges may require replacement. The dentist will look at the filling and explain whether polishing could improve its appearance enough for you.
Will a new filling match my teeth?
Composite fillings are shaded to match surrounding teeth. If you plan to whiten your teeth, do it before replacement so the new fillings can be matched to your lighter shade rather than the original colour.
