You had a crown or filling done, and now the nightguard will not click into place the way it used to. From Acton, bring the appliance in so its fit can be checked against your new dental work before you keep wearing it.
It is a very ordinary moment. You get home from having a tooth restored, reach for the guard at bedtime, and it feels tight on one side, rocks slightly, or simply will not go on. Nothing is wrong with your effort. The shape it was made for is no longer quite the shape in your mouth.
That matters because a nightguard works by sitting evenly over the teeth during sleep, giving them a protective surface to close against. An appliance that no longer seats properly may press on the new restoration or the teeth around it. Even when it fits well, a guard protects surfaces; it is not designed to stop grinding, end jaw discomfort, or rebuild worn enamel.
If you are travelling from Acton, bring the guard to your next appointment rather than pushing it into place at home. Tell the team which tooth was treated and when, and whether the work was done here or elsewhere. With that information, the dentist can check the fit and discuss whether adjustment, replacement, or simply a review is the sensible next step.
Any decision about a guard should rest on what the examination shows. Describe what you have noticed since your dental work, and also mention older concerns, since they may be separate from the new problem.
Point out the treated tooth and any others that look chipped, flatter, or newly sensitive. Ask whether the wear looks recent or reflects an older pattern worth tracking. If a restoration seems high, rough, or sore, it may need checking on its own before an appliance is reconsidered.
Let the dentist know whether someone still hears you grinding and whether you notice daytime clenching. These are separate habits. A guard worn while you sleep does nothing for waking clenching, which may need different advice.
Tightness, looseness, pressure on one tooth, or soreness after wearing it all suggest a fit problem. Stop forcing it. Bring the appliance with you so it can be compared with your teeth as they are now.
Pain in a newly restored tooth, swelling, a jaw that locks, or real difficulty chewing needs assessment of that specific issue. Covering a new problem with an over-the-counter guard will not fix its cause.
When a guard and a restoration are planned together, each can support the other. Ask which teeth and restorations the appliance is meant to protect, what will be checked at review, and whether any further treatment is coming. Timing a new guard after planned crowns or fillings can avoid having to make it twice.
A professionally made appliance also needs a proper fitting and later review. Raise anything that makes wearing it difficult, such as gagging, sensitivity around the new restoration, or trouble seating it with your hands. Practical problems are easier to solve while the design is still being discussed.

Review the proposed coverage and material, and ask why that design suits your current examination. If more restorative work is planned, find out whether it should be completed first, since an appliance made around an old tooth shape can stop fitting once that tooth changes.
Shielding tooth surfaces does not promise relief from jaw pain or headaches. A grinding guard is also different from an appliance prescribed as part of sleep-apnea treatment. If breathing during sleep is a concern, raise it so the right assessment can be arranged.
Agree on how often to bring the guard back, and remember that any new filling or crown is a reason to check it again. Reviews look at fit, condition, and how you are getting on, so problems are found before they cause discomfort.
The number of visits depends on what the dentist finds and whether the appliance can be adjusted. Ask what is involved at the start, including whether new records are likely to be needed.
Bring the appliance and describe when the fit changed, which tooth was treated, and any symptoms since. The dentist examines the restoration and surrounding teeth and considers whether something else needs care first. Ask what the findings suggest before any decision is made.
Some fit changes can be refined; others need a new appliance. If a replacement is recommended, talk through coverage, material, expected fees, and how you will wear it. Fresh scans or impressions may be taken once any remaining restorative work is finished.
Whether it is the adjusted guard or a new one, practise putting it in and taking it out at the appointment. Mention pressure on the new restoration, rough spots, or trouble seating it, and leave with clear instructions for wear and care.
Arrange a follow-up and confirm which problems should prompt an earlier call. Bring the guard to routine visits, and tell the team about any further dental work. Reviews look at your experience, symptoms, and the device's condition.
Appliance materials have different needs, so follow the instructions supplied. If you are not sure about cleaners, storage, or how often to wear it, ask for a demonstration or written guidance.
Brush your teeth, including the restored tooth, before wearing the guard, and clean the appliance as directed once it comes out. Ask which cleaners suit its material rather than reaching for any household or denture product. Avoid hot water, which may warp it, and keep its case clean.
Use the case every time, and keep it away from heat, pets, and anywhere it might be crushed. A tissue makes it easy to throw away by mistake. Ask about storing it during travel or a period when you are not wearing it.
If the guard hurts, stop wearing it and contact the clinician who made it. Do not trim, heat, bend, or glue it to make it fit. A crack, sharp edge, lasting bite change, or difficulty seating it should be reviewed professionally.

Your questions and the appliance itself are both useful here. Advice should reflect your new dental work, the condition of the guard, and what to do if wearing it becomes uncomfortable.
Phone (905) 876-4488 to book with our Bronte Street practice. Bring the appliance, let us know which tooth was treated and where, and mention any work still to come, so we can talk through adjustment, replacement, or review.
Guard suitability, design, lifespan, and how symptoms respond all vary. A grinding guard does not diagnose or treat sleep-related breathing disorders, which need assessment and prescribed care of their own.
