Best dentist in Adambakkam | The Link Between Mouth Breathing and Crooked Teeth Mouth breathing, especially in children, can significantly affect jaw development and lead to crooked or misaligned teeth. When you breathe through the mouth instead of the nose, the tongue doesn’t rest in its natural position on the palate. This impacts facial growth, narrows the dental arch, and can cause overcrowding of teeth over time. It may also lead to bite problems and long-term oral health issues. At Dr. Akkshaya Dental & Aesthetics, we identify early signs of mouth breathing and provide customized treatments, including myofunctional therapy and orthodontic solutions, to support healthy jaw development and proper teeth alignment.
