If you've recently had a dental crown or bridge fitted, it may alter the fit of your existing splint or mouthguard, as these appliances are custom-made to fit your teeth exactly. You should bring your splint or mouthguard to your next dental appointment so your dentist can check the fit. If it no longer fits properly, it may need to be adjusted or in some cases a new one may need to be made.

It's important to maintain the use of these appliances if they've been recommended, as they can protect your teeth from damage, particularly from grinding or clenching during sleep.
