2. BE SURE TO WEAR IT EVERY NIGHT. For a night guard to be effective it must be worn every night. If it is left out for extended periods, the upper teeth may move slightly and then it may not fit properly. If this occurs it may have to be remade.
3. TEETH SENSITIVITY. Your may experience tooth sensitivity from the confinement of the night guard. This usually lasts only 2 to 3 days and will not reoccur as the teeth get used to the night guard.
4. INCREASE IN SALIVA. You may also notice an increase in saliva due to the foreign material in the mouth. It does not last long and it does get better as you get used to wearing your night guard.
