Best dental clinic in Adambakkam | How Breathing Through Your Mouth Affects Your Smile Mouth breathing isn’t just a habit — it can affect your oral health and facial development over time. Constant airflow through the mouth can lead to dry mouth, bad breath, and a higher risk of cavities and gum disease. In children, it may cause narrow jaws, crooked teeth, or even changes in facial structure. At Dr. Akkshaya Dental & Aesthetics, we help identify the root cause and guide you with corrective solutions like myofunctional therapy, orthodontics, or habit-breaking appliances. Breathe better, smile brighter!
