Replacing a filling should be based on a clear reason.
Fillings do not last forever. Over time they can wear, crack, stain or develop gaps where new decay starts. Some people also want to replace visible metal or discoloured fillings for appearance. Not every old filling needs replacement, though, and removing a sound filling also removes some tooth structure.
If you are in Cultus and wondering about your older fillings, our Port Dover dentists can examine them and explain whether replacement is advisable. We will discuss the condition of each filling, the options for new materials and what replacement involves. Some fillings are best left alone.
Reasons to replace
Several factors can signal a filling has reached its limit.
Wear, cracks and decay
Fillings can develop cracks, chipped edges or gaps where bacteria enter. Decay can form underneath, sometimes without symptoms. Teeth with large old fillings may develop fractures. The dentist checks fillings visually and with X-rays to identify problems that justify replacement. Sensitivity to cold or sweets near an older filling, or floss that catches and shreds, can be early signs worth mentioning.
Appearance concerns
Some people want to replace dark metal fillings or stained tooth-coloured fillings that show when they smile. Cosmetic replacement is a valid choice, but the dentist will explain the trade-off, since each replacement removes some tooth structure. Understanding this helps you decide. For a filling that is otherwise sound, it may make sense to wait and replace it when it eventually needs attention for another reason.
Assessment
The dentist evaluates each filling individually.
Checking the filling and tooth
Each filling is examined for wear, fractures, staining and signs of decay at its edges. X-rays help detect hidden decay. Teeth with cracks or sensitivity are noted. The dentist will explain the condition of each filling and whether it is functioning well or showing signs of failure. Photos can make the explanation easier to follow.
Deciding which to replace first
If several fillings need attention, the dentist can help you prioritize. Fillings with decay or cracks are usually addressed first, while cosmetic replacements can be planned later. Ask about the number of visits involved and whether treatment can be grouped to reduce trips from home. Working on one side of the mouth at a time is a common way to arrange longer visits comfortably.
Replacement options
The size of the old filling guides the new choice.
Composite fillings
Small and moderate fillings are often replaced with tooth-coloured composite, which bonds to the tooth and blends with natural colour. Composite can be shaped to restore the tooth’s contour. It may stain over time with coffee, tea or tobacco, and may not suit very large restorations in heavy biting areas. The dentist will be clear about where its limits lie.
Inlays, onlays and crowns
When an old filling is very large or the tooth is weakened, an inlay, onlay or crown may provide better support. These laboratory-made restorations can be more durable. The dentist will recommend an option based on how much healthy tooth remains and the forces it takes. Teeth with cracks beneath an old filling often benefit from this extra support.
Aftercare
New fillings need the same care as natural teeth.
Sensitivity and adjustment
Some sensitivity to cold or pressure is common after replacement and usually fades. If the bite feels high or discomfort worsens, contact the office for an adjustment. Wait until numbness wears off before eating to avoid biting your cheek or tongue. Teeth that held large metal fillings may feel different for a while as they adjust to the new material.
Keeping new fillings healthy
Brush twice daily with fluoride toothpaste and clean between teeth to prevent decay around the new filling. Avoid chewing ice or hard objects. Regular checkups allow the dentist to monitor your fillings and catch problems early, extending their lifespan. If you grind, a night guard helps protect new restorations, and rinsing after coffee or tea can slow staining of tooth-coloured materials.
Planning your appointment
Filling reviews from Cultus
Call our Port Dover office to arrange an assessment of your older fillings. Let the team know if any are causing sensitivity or if appearance is your main concern, so the visit can be planned.
If you have X-rays from another office, ask for them to be sent. This can help the dentist compare changes over time.

Filling replacement questions
Have a question about your situation? Our team can help you plan a visit.
Should I replace all my metal fillings?
Not necessarily. Sound fillings without problems may not need replacement. The dentist will assess each one and explain the benefits and risks of replacing it. Fillings with decay or cracks are usually the first priority.
Are metal fillings dangerous?
Health organizations generally consider amalgam fillings safe for most people. If you have concerns, discuss them with the dentist, who can explain the evidence and your options. Removing a sound filling also has trade-offs to consider.
Will replacing a filling hurt?
The tooth is numbed during treatment, so most people feel little discomfort. Some sensitivity afterward is common and usually resolves within days or weeks. Call if it lingers or the bite feels uneven when chewing.
How long do composite replacements last?
Lifespan depends on size, location and care. Many last for years. Regular checkups help identify wear or decay early so it can be addressed promptly. Larger fillings tend to need replacing sooner than small ones.
Can stained composite fillings be polished instead?
Sometimes surface staining can be polished away. Deeper discolouration may require replacement. The dentist will assess whether polishing is enough. Trying the simpler option first is often sensible, since it preserves the existing filling and tooth structure.
