Mouth breathing is a common problem that can have serious consequences, including:

  • Tooth Decay
  • Bad Breath
  • Dry Mouth
  • Jaw Development in Children

Left untreated, dry mouth can also lead to tooth fractures through advancing decay.

Fortunately, there are ways to combat mouth breathing and protect your dental health.

Reasons for Mouth Breathing and How Your Dentist in Houston Can Help

Temporary mouth breathing during sleep may result from allergies, colds, or rhinitis. When mouth breathing lingers or worsens, it may be related to the following:

  • Structural Issues: Deviated septum, enlarged adenoids/tonsils, nose polyps
  • Anxiety: Feeling anxious, afraid, or unsure
  • Specific Conditions: Habitual mouth breathing and sleep apnea

Combating Dry Mouth and Mouth Breathing

Of course, the best way to combat dry mouth and mouth breathing is to learn why they are happening. In the meantime, it’s important to keep your mouth hydrated by drinking lots of water. You can also use a humidifier. Sugarless gum can help produce saliva to prevent tooth decay.
