I'm thinking of buying a cheap mouth protector, basically a piece of rubber you put inbetween your teeth to avoid injury. I have one in mind that costs 12$, but as this is the first mouth guard I'm buying, I don't really know what to expect and have some questions;
Does it grip both my higher and lower teeth?
Can I still somehow bite my tongue?
How much does it help?
I've worn braces, so I'm really scared about my teeth sometimes.
Because of the braces, I have many cuts on the back sides of my teeth that really hurt if I bite on the back of my upper teeth.
