Mouth Ulcers

Mouth ulcers are sores that form on your gums, lips, cheeks, or palate, and can cause pain or discomfort in the region. They often resolve spontaneously in a few weeks but persistent mouth ulcers require further investigation and medical attention.
Mouth ulcers are most commonly caused by the following reasons, including:
  • Minor tissue injuries
  • Accidentally biting your tongue or cheeks
  • Wearing braces
  • Using harsh toothpastes
  • Eating foods with high acidity
  • Hormonal changes
  • Stress
  • Inadequate sleep
  • Oral infections
Mouth ulcers often appear similar to sores, with red edges and a white or yellow centre. They cause immense pain and discomfort to the person. Some other symptoms of mouth ulcers can include:
  • Swelling around the ulcer
  • Pain that can worsen when eating
  • Soreness when brushing your teeth or experiencing movement in the region
Mouth ulcers can happen to anyone, regardless of age and gender. However, your chances of developing ulcers can be increased in:
  • Smokers
  • Betel nut chewers
  • Poor dental hygiene
  • Sharp teeth
  • Diabetes
  • Autoimmune disorders


Most mouth ulcers heal on their own in a few days. However, if you are a smoker, getting frequent ulcers, having a non-healing ulcer, or an enlarging ulcer, you should seek treatment with a doctor. These are red flags symptoms and should be investigated as soon as possible to ensure there is no underlying malignancy.


While you cannot completely prevent ulcers, you can reduce your chances of developing one by following simple hygiene and lifestyle habits, including:
  • Ensure good hydration
  • Stop smoking
  • Ensure good dental hygiene
