Bad breath (halitosis)

Bad breath, or halitosis, affects approximately 65% of the population. Temporary halitosis occurs when less saliva is produced during sleep, combined with decreased tongue and cheek movement. A balanced breakfast and thorough brushing of the teeth and tongue will help freshen your breath.


  • Swollen gums or gum disease
  • Poor oral hygiene
  • Cavities or defective restorations
  • Food particles between teeth
  • Infection
  • Breathing through the mouth
  • Smoking
  • Diminished saliva production
  • Accumulation of bacteria and food particles on the tongue

Mouthwash only temporarily masks bad breath. When overused, mouthwash can actually irritate your mouth’s mucous membranes and aggravate the problem. Proper oral hygiene and regular dental check-ups are very important. If your bad breath persists, contact us today and our team will provide you with helpful advice to remedy the problem.
