Oral Ulcers

Ulcers are breaks or discontinuity in the mucous membrane in the oral cavity. Ulcers may be single or multiple when manifesting itself. 


  • Chemical burns
  • Thermal burns
  • Trauma or damage to mucous membrane
  • Stress or hormonal imbalance
  • Viral or bacterial infection in the oral cavity


Ulcers may appear at any time or place in the mouth. The few most common spots ulcers form.

  • Corner of the mouth
  • Upper and lower lip
  • Floor of the mouth
  • Both sides or below the tongue
  • On the cheeks beside the molar teeth


-Ulcers may appear as a indurated base surrounded by a red halo and is usually covered by a mucous membrane

-Ulcers usually heal in a span of 2 to 3 weeks and without any scarring to the normal tissues in the oral cavity


To treat ulcers, 

  • Maintain good oral hygiene by brushing teeth and using mouthwashes
  • Avoid hot, spicy and sour foods while the ulcer is healing
  • Apply gels or medication on to the ulcer 3 times a day to prevent any secondary infection (some gels contain painkiller properties and can be obtained at any local pharmacy)
