Replacement of Worn Fillings in Burlington

Has one side of your mouth started doing most of the chewing? Coming from Burlington, you can have a flattened filling assessed and learn whether it should be watched, rebuilt or replaced.

Chewing on the other side?

When a back tooth stops pulling its weight

People rarely decide to favour one side of the mouth. It just happens, perhaps because a molar with an older filling now feels smooth and slippery instead of firm against food. Noticing that shift is a reasonable cue to have the tooth looked at.

Years of chewing can round off the ridges and grooves that a filling was originally shaped with. The result may be harmless, or it may change how the teeth meet, how food is broken down and how the area is cleaned. Telling those situations apart requires an examination of the filling, the natural tooth and the opposing teeth together.

For a visit from Burlington, note which tooth feels different, when you first noticed and whether it is comfortable. If a previous dentist mentioned wear or you have older records, bring that information. We will explain the findings and whether monitoring, reshaping, repair or a new filling would make the most sense.

Worth a mention

Is the tooth still working the way it should?

A changed filling can be an isolated issue or a sign of wear elsewhere. Looking at the bigger picture shows which is more likely.

Less grip when you chew

Food may slide around rather than break down, or the bite may feel softer on that side. Tell the dentist whether the tooth is comfortable and still useful. The surface is assessed against the teeth it meets and your bite overall.

Changes when you clean

New catching with floss, food sitting beside the filling, or an edge you can feel with your tongue can point to an altered contact or margin. There are several possible causes, so describe where and how often you notice it.

Flattening across the mouth

When several teeth or fillings look worn, mention clenching, grinding or earlier advice about wear. The dentist may need to consider the wider pattern before concluding that replacing one filling will deal with what you have noticed.

The age of a filling is a weak guide on its own. Its condition, the tooth surrounding it and how it performs today tell the dentist much more.

Sensible restoration

Restore the bite without overlooking the cause.

If treatment is recommended, the intention is to give the tooth a useful chewing surface and a contact that can be kept clean, while still thinking about what wore it down. That may be a small repair or an entirely new restoration. Ask what makes treatment preferable to keeping watch.

The material and contour should suit the demands that tooth faces. When wear is spread across the mouth or tied to the bite, one replacement filling may be just part of the plan. Knowing that early helps you set realistic expectations.

A specific trigger for treatment

You should understand whether the issue is the surface, the margin, the tooth below or something else. A filling should not be replaced only because it looks older or has lost some of its sheen.

Conservation where it fits

Some fillings can be watched or repaired locally while the sound parts stay. Ask whether healthy restoration and tooth can remain. That depends on the defect and on keeping the result functional and cleanable.

Thinking about chewing forces

Mention habits that load your teeth heavily, from clenching to chewing ice. Protection or a broader wear review may be relevant, since new material does not change the forces that wore the old surface.

The visit itself

Four parts to a worn filling appointment

Your appointment could be an assessment, a repair, or part of a staged plan. It is worth asking what the dentist wants to learn and what may be proposed.

  1. Assess the tooth and your bite

    The dentist checks the filling’s surfaces and edges, the surrounding tooth and how your teeth come together. Symptoms and previous records are considered, with imaging when it helps. Mention discomfort, repeated repairs or chewing changes.

  2. Decide together on next steps

    You will hear the reasons for monitoring, repair or replacement. Ask about materials, fees and whether a broader wear assessment is needed. If watching is advised, confirm what will be reviewed and which changes should prompt a sooner call.

  3. Rebuild the surface if agreed

    If you go ahead, the tooth is kept comfortable and isolated. How much of the old material is removed depends on its condition and the tooth underneath. The new or repaired surface is then shaped to restore useful chewing.

  4. Fine-tune how the teeth meet

    The repair is checked against neighbouring and opposing teeth so the bite feels balanced. Ask about cleaning and follow-up. If wider wear was seen, confirm what further assessment or protective advice still applies.

Settling in

Chew normally and notice how it feels.

Follow the advice given for your restoration. You do not need to test it on unusually hard food to see whether it is holding up.

Wait until you can feel your lip

Avoid chewing while you are still numb and be careful with hot food or drinks. Follow any extra instructions for the material or a temporary stage. Ask when you can use the tooth normally if it was not explained.

Report a bite that feels high

Call if the repaired tooth seems to touch before the others or chewing stays uncomfortable. Describe an ordinary bite rather than clenching to check it. A review can examine the restoration and any other cause.

Return to using both sides

Once comfortable, you can usually go back to chewing evenly. Keep cleaning well and attend your reviews. If a night guard was discussed, ask how it fits your routine, and mention any appliance that is damaged or hard to wear.

Your options

Not every flat filling needs the same answer

The appropriate amount of treatment depends on what has been found, and two fillings in your mouth may call for different approaches.

When the wear is acceptable to watch

Keep an eye on it

A filling that still works and can be maintained may be monitored. Agree on when it will be checked and which symptoms to report. Monitoring reflects present condition and is not a guarantee that the restoration will never need attention.

When a partial repair is suitable

Rebuild a limited area

A worn cusp or edge can sometimes be addressed without replacing the entire filling. The dentist can explain whether this is appropriate for you and what it will not change. Ask how the result will be assessed later.

When the existing filling no longer serves

Place a new restoration

Significant wear or related damage may mean a new filling or a different restoration type. Discuss how much tooth remains and the load it carries. More extensive damage may need a plan beyond another direct filling.

Burlington questions, answered

Worn fillings and the way you chew

You should leave a review knowing the filling’s current condition and the reasoning behind any recommendation.

(905) 876-4488
Why does a filled molar feel less effective for chewing?
A filling’s original grooves and ridges can wear smooth over time, which may change how food is broken down. Opposing teeth and your bite also play a part. The dentist assesses the whole area before deciding whether the change needs treatment.
Is it a problem to chew mostly on one side?
Favouring one side is often a sign that something feels different. It is worth having the less-used side examined. The dentist can look for wear, sensitivity or other causes and explain whether any care is needed.
Can a rebuilt filling restore the shape of the tooth?
A new or repaired surface is shaped to suit how the tooth needs to function. How closely that matches the original depends on the remaining tooth and the bite. Ask what the dentist is aiming for in your case.
Does tooth-coloured material wear differently from older fillings?
Different materials have different properties. The dentist chooses based on the size of the restoration, the remaining tooth and the forces on it. Ask how the options compare for your particular tooth, including how they are maintained.
If one filling is replaced, will my other teeth stop wearing?
Not by itself. A single repair does not address the causes of wider wear. Ask whether a broader assessment is recommended and what the replacement is specifically meant to improve. Other advice or care may be part of the plan.
How soon after a replacement can I chew normally?
That depends on the material and any temporary stage. Wait until the numbness has gone before chewing. The dentist will tell you when ordinary use can resume, and you should ask if you are unsure.
