Fluid: Saliva doesn't necessarily have a role in cleaning your teeth. It would matter if you didn't have saliva while cleaning your teeth.
Dr. James Donley
Dentistry 54 years experience
Reduces cavities: Saliva keeps your mouth and teeth moist. When dry there are more cavities because there is a loss of the buffering action against the acids that occur in plaque. With adequate saliva, you can clean better and less tartar will form.

Mouth guards: Almost every dentist can make you a custom mouth guard. You shouldn't buy a mouth guard that is not made for you specifically or it can cause problems. Just like one size fits all shoes aren't a good idea.

Possibly: It is not a for sure thing that you would have an infection but those symptoms common for an infection that is draining such as an abcess. You may want to have a dentist take a look for you.
