A : A new guard would be the best solution. They can and will eventually wear out. The degree of grinding and clenching with determine the longevity of the appliance. Think of it as a tire, once it goes bald you could retread it, plug it etc. But a new one is the best and safest way to go.

Dr. : Dr. Muck said it best, you most likely will need a new appliance. That being said, go to your dentist and have him/her take a look at it. If it is still servicable, they may be able to reline it with some acrylic in the office to make it a bit tighter. Hard to tell how worn down your appliance is, sight unseen.

Spokane, Time : Spokane, time for a new nightguard. I have made several attempts over the years to squeeze some more life out of these for my patients. It never seems to work for me or them. It is always better, healthier, and cheaper to get a new night guard rather then a new set of teeth. Hope this is helpful, michael i.

As : As mentioned by dr.Jason david muck, it looks that your night guard is asking you to be replaced. Repairing a night guard is almost impossible, because they are usually made under a vacuum suction pomp, to be seemingly adapted to your teeth. Go to your dentist and request from him a new nightguard. Good luck.

Nightguards : Nightguards by design wear out and are then replaced. Getting loose over time is normal and some materials wear out or get loose quicker than others, so to get the most return on your investment, ask for the most durable material that your dentist can offer.

Can be repaired: There are 2 basic types of night guards: one is made by a vacuum formed thermoplastic, which is light, bendable and less durable. The other type is made of hard acrylic, fabricated in a much different way, is harder and more durable. If the second type becomes a bit loose from wear or excessive heat, it can be relined on a new plaster model and give years of service. So, it depends. First type, no.
