A flattened or reshaped surface
You may have noticed a smoother feel while chewing, or been told the outline has changed. Say whether the tooth is comfortable. Its surface is assessed with the opposing teeth and your bite in mind, not in isolation.

Replacement of Worn Fillings in Mississauga
Been advised to replace several older fillings and want to understand why? If you are coming from Mississauga, we can review each restoration and explain, tooth by tooth, what the wear does and does not mean.
Understanding a recommendationAsk for a filling-by-filling review
Each filling gets its own verdict.
Hearing that several fillings need replacing can feel like a lot at once. It is reasonable to want the reasons laid out clearly, filling by filling, before agreeing to treatment. A careful review should make that possible, whatever it concludes.
Worn is a broad description. For one tooth it may mean a smoothed chewing surface that still works well; for another, an edge that has opened or a contact that now traps food. The dentist weighs each restoration against the natural tooth around it and the way your teeth meet, then decides what, if anything, that particular tooth needs.
If you are travelling from Mississauga, bring any treatment plan or notes you were given, and recent images if you have them. Tell us what you have felt yourself. We will explain our own findings in plain language and point out where monitoring, a smaller repair or replacement seems most appropriate.
What to describe
Your own observations sharpen the review.
Some changes are local to one restoration. Others are part of a wider wear pattern, and treating them one filling at a time may miss the bigger reason.
Floss or food behaving oddly
A new snag, shredded floss or food packing into one gap can indicate a change at the edge or contact. The same signs can arise for other reasons. Point to the location and say how often it happens.
A pattern across many teeth
Wear on several restorations may relate to clenching, grinding or other habits. Share anything you know, including earlier advice. Understanding that pattern matters before deciding whether new fillings alone would help.
There is no standard lifespan after which every filling should be removed. Present condition, the surrounding tooth and real function are what guide the advice.
Clarity before commitment
Treat what needs it, and explain what does not.
A review is useful whether it confirms a plan or suggests a smaller one. Where treatment is warranted, the goal is a sound surface and a cleanable contact, with attention to what caused the wear. You are entitled to ask what moves a particular tooth from watching to treating.
If wear is widespread or linked to the bite, replacing fillings may only be one element of care. The material and shape chosen should reflect the load on each tooth. Knowing this helps you weigh the plan and its realistic limits.
Patient information: Cleveland Clinic — filling longevity and maintenance
Reasons stated tooth by tooth
For each restoration, you should hear whether the concern is the surface, the margin, the tooth beneath or something else. Replacement purely because a filling looks dated is not a clinical reason.
Conserving where possible
Some restorations may be fine to monitor, and others may need only a local repair. Ask which sound material and tooth can stay. The answer depends on the defect and whether the area can be maintained.
Considering the forces on your teeth
Heavy clenching or other habits can load teeth and fillings alike. Protection or a broader assessment may be worth discussing, since new material does not change the pressures acting on it.
How the review runs
From examination to a plan you can follow
This may be an assessment-only visit, or it may lead to treatment now or in stages. Ask early on what the dentist will be checking and what decisions are likely.
Examine each restoration
Surfaces, margins, the surrounding tooth and your bite are all checked. Any symptoms, previous plans and records you bring are reviewed, and imaging is used where it adds information. Mention discomfort or past repeat repairs.
Sort findings into priorities
The dentist explains which fillings could be monitored, which might be repaired and which may need replacement. Ask about materials, fees and sequencing. For anything being watched, agree on what will be compared and what should prompt a call.
Carry out treatment as agreed
When work goes ahead, the tooth is kept comfortable and isolated. The amount of old material removed depends on what is found. The new or repaired surface is shaped to suit that tooth’s role in your bite.
Check the result in your bite
The finished tooth is assessed against its neighbours and the teeth opposite. Ask how to clean it and whether a review is planned. If wider wear was noted, confirm which further step or protective advice applies.
Afterwards
Normal days are the real check.
Your dentist will give instructions for the particular repair. Testing it on very hard food is unnecessary and could be unhelpful.
Be patient with numbness
Do not chew until sensation returns, and take care with hot drinks or food. Follow any instructions about the material or a temporary stage. If you are unsure when the tooth can return to normal use, ask.
Pay attention to your bite
Contact the clinic if the treated tooth feels like it meets first or chewing stays uncomfortable. Describe an ordinary bite instead of repeatedly clenching. A review can check the repair and other explanations.
Keep the remaining plan in view
If other fillings are being monitored or treated in stages, keep the next appointments. Continue cleaning well. If protection for grinding was suggested, ask how it fits your routine, and mention any problem wearing an appliance.
Questions we hear from Mississauga(905) 876-4488
Getting clear on a replacement plan
A good review explains both the condition of each filling now and the reasoning behind each suggested step.
Is it reasonable to ask for a second opinion on replacing fillings?
Yes. Understanding the reasons for treatment is part of informed consent. A second review can confirm a plan or explain a different view. Bring any notes or images so the dentist has as much context as possible.
Do all my worn fillings need replacing at the same time?
Not necessarily. Each restoration is assessed on its own merits. Some may be monitored while others are repaired or replaced, and treatment can sometimes be staged. Ask how the dentist would prioritise them and why.
What should I ask about each filling before agreeing to treatment?
Ask what was found, whether it affects the surface, edge or tooth beneath, what the options are, and what might happen if you wait. Asking about materials and fees is also reasonable before you decide.
Can images from another clinic be used for my review?
Recent records can provide helpful context, and you can ask your previous clinic to send them. The dentist will still examine the teeth directly and decide whether new imaging is needed for an accurate assessment.
Is a smooth, shiny filling a sign that it is fine?
Appearance alone does not settle it. A filling can look smooth and still have a problem at the margin, or look worn and remain functional. The dentist considers function, the edge and the surrounding tooth together.
Could replacing several fillings be planned over more than one visit?
Often it can, depending on the findings and your preferences. Discuss sequencing with the dentist so the most pressing teeth are addressed first. Planning this way can also help if you are travelling in for appointments.
