Materials & Thickness
Due to the rigid nature of the 3mm material, this thick mouth guard will have a tighter fit and is therefore slightly less comfortable than our other styles; however, the trade-off is that this hard dental guard provides the strongest protection and durability for grinding, clenching, and severe bruxism.
Why You’ll Love It
Severe bruxism requires an extremely thick night guard to act as a protective barrier from heavy grinding and clenching. This ultra-hard model can provide much-needed relief for a variety of symptoms related to bruxism, including headaches, jaw pain, difficulty sleeping, and more. To ensure that everyone can use our products, we only use premium materials that are always BPA-, monomer-, latex-, gluten-, and allergy-friendly.
