What is the direct answer?
Repeated inner-lip biting is usually a mechanical or habit-related injury in which the lip is caught between teeth during chewing, clenching, or stress.
What does this question mean?
A sharp tooth edge, a new filling, dentures, braces, an altered bite, or cheek and lip muscle coordination can keep reopening the same spot.
What can you do next?
Look for the trigger, chew slowly, and avoid repeatedly testing the sore area. A dentist can smooth an edge, adjust a restoration or appliance, and examine the tissue for a persistent ulcer.
When should you seek dental care?
Have a non-healing sore, firm lump, bleeding area, or recurrent wound examined promptly.
What should you ask the dentist?
If clenching or anxiety drives the habit, treatment may include bite assessment, habit awareness, and a plan for the contributing muscle activity.
