BEST DENTIST IN ARUMBAKKAM! Smoking tends to dry out the mouth and give bacteria an environment in which to thrive. Tobacco smoke leaves residue on the teeth and tongue, creating a breeding ground for bacteria. Additionally, smoking reduces saliva production, which is crucial for neutralizing odors and washing away food particles and bacteria. The combination of these factors contributes significantly to bad breath. If you suspect that your breath is off-putting to others, schedule a checkup. In just minutes we at Apple Dental can assess your oral hygiene and determine not only the cause of your bad breath, but provide a care plan to eliminate it.
