Low Mouth Opening

Low mouth opening, also known as trismus, is a condition where a person is unable to open their mouth fully. This can affect eating, speaking, oral hygiene, and dental treatment. It often results from muscle stiffness, infection, trauma, or long-term habits like tobacco chewing.

Common Causes:

• Oral submucous fibrosis (OSMF – typically due to gutkha or tobacco use)

• Post-surgical scarring

• Muscle spasm or temporomandibular joint (TMJ) issues

• Dental infections or trauma

• Tumors or fibrosis in oral tissues

Treatment Options:

1. Clinical evaluation and measurement of mouth opening.

2. Medication to reduce inflammation and relax muscles.

3. Mouth-opening exercises and physiotherapy.

4. Laser or surgical procedures in severe cases (e.g., for OSMF).

5. Habit counseling for patients using gutkha, pan masala, or tobacco.

When to Seek Treatment?
If you are unable to open your mouth properly (less than 35–40 mm), experiencing pain, or facing difficulty in eating or speaking, timely treatment is necessary to avoid complications.
