If you suffer from bad breath, you are not alone. Bad breath, also called halithosis can be downright embarassing. Several reasons for this includes thick plaque and calculus from lack of dental hygiene care, dental decay, retained broken down roots or even a badly fitting denture. Drinking plain water more often and rinsing with mouthrinse help reduce bad breath. For a better solution, consult a dentist to find out the source of bad breath.
