## Description

JAPSUN silicone mouth guards, which are made according to Japanese high quality standards, help people who suffer from Bruxism and other jaw problems.  Packed in an anti-bacterial case, the two included dental guards are suitable for both adults and kids - for upper or lower teeth.  • Prevents Temporomandibular Joint Disorder (TMJD)  • Not bulky or thick, soft and pleasant • Made of FDA silicone (U.S. Food and Drug Administration 21CFR 177.1350)  • Comes with a case • Perfect for men, women, and children Step-by-step instructions:  1. Put the mouth guard in hot water for 20-25 seconds; it will begin softening.  2. Take it out of the water, cool it down to an acceptable temperature, and put it into your mouth so that it can take the shape of your teeth.  3. When it is completely cooled, you will have a custom-fitted dental guard.  Important to know:  - Do not mold it twice.  - If a dental guard is slightly long, you can cut it to your size.

## Features

- A dental guard is ideal for those who suffer from teeth grinding, jaw clenching, and related problems such as joint pain, headaches, neck and muscle pain, insomnia etc.
- Suitable for adults and children, this set consists of 2 mouth guards of different sizes (small and big), which are produced according to Japanese quality standards and are packed in an anti-bacterial case.
