The Ultra Hard Night Guard

The Ultra-Hard Night Guard is our strongest and most durable night guard designed and suited for heavy grinders and clenchers. The rigid surface acts as a highly effective protective barrier against the grinding forces of your teeth and is made out of a hard elasticized copolyester material, approximately 3 mm thick. Due to the rigid nature of the material, it will be a tighter fit and therefore slightly less comfortable than our other styles but will provide the strongest protection and durability for grinding, clenching, and severe bruxism.

The Ultra Hard Night Guard at Clear Comfort Night Guards is designed to help you manage heavy teeth grinding and clenching. It’s one of the sturdiest night guards we have, about 3mm thick. It’s made of a hard elasticized copolyester and is designed to ensure maximum protection.

So, if you experience a more severe form of bruxism, the ultra-hard night guard is the perfect fit for you.

Given its sturdier design and material, the ultra-hard night guard will likely last longer than many other types of dental guards we offer. However, it's also worth considering that its actual lifespan depends on usage, and since this particular night guard is likely to be used by heavy teeth grinders, it may get damaged over time.

That said, if the night guard is used carefully, cleaned, and maintained after every use, it’s likely to last much longer. Make sure to store the night guard in its case for maximum protection.

All night guards are crafted based on the impression you send us using the impression kit. If in case your night guard doesn’t fit well, we’ll be happy to identify issues and fix them for you or design a new one.

Of course, we also offer complete refunds within 45 days if you do not wish to use our night guard.

The night guards we craft at Clear Comfort Night Guards are also custom night guards created using the impressions sent in by our customers. These are designed to fit perfectly based on your dental structure.

On the other hand, OTC night guards are dental guards that are generic and mass-produced. Needless to say, they do not offer the level of comfort that our custom night guards provide.

Usually, night guards have varying lifespans and could last anywhere between 6 months to 5 years. However, you should regularly inspect your night guard to check if it is damaged or has changed shape, in which case, it should be replaced.

Also, if your night guard feels more uncomfortable and out of place than usual, it could be due to it losing its shape. If you’re experiencing something similar, consider replacing your nightguard.
