The right half of my mouth hurts...just jaw, teeth and a little cheek. it started randomly last night around 9 p.m. its not a constant hurting.

Dental Exam: Very vague symptoms. Since it is your teeth and cheek, it could be from your sinuses or your teeth. Have your dentist take a look.

Dental Check-Up: If your wisdom teeth are not all fully erupted yet, it can cause discomfort if there's no room for it to erupt. See your general dentist first to get a proper diagnosis.

See a dentist: A tooth abscess won't go away without treatment. A dental abscess is a collection of pus that forms in your teeth or gums as a result of a bacterial infection. The dentist will treat a tooth abscess by draining it and getting rid of the infection. See a dentist for a treatment ASAP.

Cavity?: You may have a cavity in that area. Or even a cracked tooth. You wisdom tooth (3rd Molar) may be causing some discomfort. See your dentist as soon as possible to check all possibilities.
