If your implantologist has recommended a night guard then the simple answer to this is YES.
A dentist can tell that you grind your teeth just by examining them. There will be telling signs on your back teeth. We know that movement of implants is one of the biggest contributors to them failing and to crowns or bridges needing to be prematurely replaced, as well as the risk of chipping your teeth. Dental implants take time and money, and of course you would want to protect and look after them view our advice on dental implant aftercare.
If you are a known grinder you can protect both your natural teeth and implants by getting a bite guard to wear at night which can provide a buffering surface for you to grind on. We are able to arrange this for you here or your normal dentist should be happy to assist. A mould of your upper teeth will be taken and a personalised night guard will be made for you to wear.
You will need to wear this every night. A mouth guard can also be made and worn if you regularly do sports or activities that could risk a trauma to the mouth. A mouth guard can protect your teeth and implants by reducing breaks, fractures, chips or movement caused by an impact. Temporomandibular Joint Disorders (TMD, TMJ) is also a common cause of teeth grinding and can be very uncomfortable. A night guard can also help with this condition, which can lead to headaches, acute jaw pain, ear ache and dizziness.
