The same filling has broken twice this year, or a front edge keeps flaking. Before another repair, our Milton team looks at whether grinding or clenching may be loading the tooth, what needs protecting, and what truly needs fixing.
A patched molar that cracks again a few months later is frustrating, and it is often the point where grinding enters the conversation. Clenching and grinding, known together as bruxism, press teeth against each other with considerable force, sometimes during sleep and sometimes during a busy afternoon. That repeated load can wear enamel and stress fillings, though a broken repair has other possible explanations too.
So the first job is to sort out what is actually happening. Flattened surfaces, small fractures and tender jaw muscles can all appear with grinding, yet acid erosion, an old restoration near the end of its life, or a single hard bite can produce similar damage. Each sign is examined on its own merits instead of being filed under one label.
For families here in Milton, that usually means a straightforward visit to our Bronte Street practice where we look, listen, and explain. You tell us about the breakages, any jaw stiffness, or a guard you already have in a drawer. We then talk about which teeth need protection, which may need repair, and why no appliance or filling can promise to end grinding altogether.
One chip can be bad luck. A run of them, or a gradual change in how your teeth look and feel, is worth describing at the visit. You do not have to be sure you grind to raise the question.
Front edges that were once slightly uneven may now seem straight and flat, which is often easiest to see when comparing photographs from a few years ago. The dentist looks at how upper and lower teeth wear against each other and weighs your age, past dental work, and other causes.
When a restoration breaks more than once, simply replacing it may lead to the same result. It helps to recall what you were doing when it broke. Material choice, how much natural tooth remains, bite forces, and habits all affect what the next step should be.
Stiff or achy chewing muscles on waking, or catching yourself clenching at a desk, can be relevant clues. They are not unique to grinding, though. Mention any locking, reduced opening, or facial pain that lingers so it receives a proper assessment.
A tooth that suddenly hurts, cracks, or feels loose should be checked soon. Being told years ago that you grind is not a reason to assume new symptoms are minor.
A night guard or similar appliance may be suggested to keep the teeth from grinding directly on each other. That can reduce further damage, but it does not grow enamel back, and it is not a cure for the habit itself. We explain what the appliance is for, how it should fit, and when it will be checked.
Clenching during the day is handled differently. Awareness of jaw posture and resting habits can be part of the discussion, and some histories suggest that a physician or sleep assessment would be wise. Stress is not assumed to be the cause for everyone, and not every worn tooth is treated with the same device.

Notes and images of your teeth and fillings today make future changes easier to judge. Ask which areas will be watched, especially if the wear is mild or you cannot tell how recent it is.
If repairs are needed, it helps to know how those surfaces will cope if grinding continues. Protecting the new work matters just as much as choosing the material it is made from.
Some people want their front teeth to look less worn; others mainly want comfortable chewing or less sensitivity. Naming your main concern keeps the plan focused and avoids the assumption that every short edge must be built back up.
There is no need to keep a detailed diary beforehand. A few honest notes about when things hurt, what has broken, how you sleep, and any guard you own give the assessment a useful starting point.
We ask whether you notice clenching, whether a partner has heard grinding at night, and when discomfort tends to show up. Your medicines, sleep, and general health are reviewed. If you think a prescription might be involved, keep taking it and raise the question with the clinician who prescribed it.
The dentist checks worn areas, cracks, existing restorations, and how your teeth come together. Jaw muscles and movement may be assessed too. Extra records or imaging are used when they answer a particular question, not as a replacement for listening and examining.
Options may include monitoring, habit awareness, a guard, or repair. If an appliance is suggested, ask about its purpose, material, fee, and follow-up. Where teeth need restoring, find out whether the work is limited to one area or part of a larger plan.
A new guard is checked for fit and comes with care instructions, while any restorations are reviewed separately. Bring the appliance to later visits so it can be inspected with your teeth. Ongoing symptoms or fresh damage may mean the plan needs changing.
An appliance only protects teeth when it is comfortable enough to wear. Clear instructions and regular check-ins do more good than a guard sitting unused because a fit problem was never mentioned.
Wear and clean your appliance the way you were shown for its material. Keep it away from hot water and sunny dashboards, and bring it to your appointments. Tell us about pressure, cracks, or a change in how your teeth meet rather than trimming it yourself.
If daytime clenching is part of the picture, simple cues to let the jaw relax with the teeth slightly apart can build awareness. Ask what suits your symptoms. Try not to keep testing your bite or grinding on purpose to see whether the habit is still there.
A new chip, sensitivity that does not settle, or jaw soreness at a different time of day is worth noting. Be candid about how often the guard is worn and what makes it hard to use. That helps separate a simple fit issue from a plan that needs rethinking.

Questions about grinding tend to blur together. A helpful answer keeps three things apart: the condition of your teeth, the source of any discomfort, and what a proposed appliance is meant to achieve.

Arrange a visit at our Bronte Street practice for recurring chips, flattened edges, or a jaw that feels tired. Bring any guard you own and tell us what has changed. Together we can sort out protection, monitoring, and whether a tooth needs repair.
Phone us about a painful crack, real swelling, or a jaw that suddenly will not move normally. Online forms are for routine requests.
