Best dentist in Adambakkam | Bad Breath and Mouthwash: Is It Advisable? Mouthwash can temporarily mask bad breath but is not a cure-all. While it helps kill bacteria that cause odors, relying solely on mouthwash may overlook underlying issues like gum disease, cavities, or poor oral hygiene. Alcohol-based mouthwashes can also cause dryness, worsening bad breath over time. For effective results, pair mouthwash with regular brushing, flossing, and tongue cleaning. It’s best to consult a dentist to address the root cause of bad breath and choose a mouthwash that suits your needs. At Dr. Akkshaya Dental and Aesthetics in Adambakkam, we prioritize your oral health with personalized advice for fresh breath and confident smiles.
