Why does my mouth twitch?

Uncontrollable spasms or contractions of the muscles around the mouth are called muscle tics or twitches. Some spasms are normal and minor, and may be triggered by stress, or a lack of sleep.

Other twitches could signal something more serious, such as Bell's palsy, where the facial nerve is damaged. Other causes of mouth twitching include muscular dystrophy, damage to the nerve that leads to a muscle, or Amyotrophic lateral sclerosis (ALS,) also known as Lou Gehrig's disease.

If you’re concerned about persistent muscle tics, contact your doctor.
