Understanding Mouth Ulcers

Mouth ulcers are small, shallow sores that appear on the soft tissues inside your mouth. They can be round or oval-shaped with a white or yellow center and a red border. While typically harmless and healing within a week or two, they can be quite uncomfortable, causing pain, burning, and stinging sensations.

A tingling sensation on your tongue, especially the tip or sides, can often signal an impending mouth ulcer. This tingling might be accompanied by a burning or itching feeling and could last for a few hours or days before the actual ulcer appears.

  2. Diet Matters: Certain foods, particularly acidic or spicy ones, can irritate your mouth and contribute to ulcers. Experiment to identify any trigger foods you might have and consider avoiding them during periods of vulnerability.
  3. Maintain Good Oral Hygiene: Brushing your teeth twice daily and flossing once a day removes food particles and bacteria that can irritate your gums and potentially contribute to ulcers. Consider using a gentle toothpaste formulated for sensitive mouths.
  4. Don’t Forget Your Vitamins: Deficiencies in certain vitamins, particularly B vitamins, zinc, and iron, can be linked to mouth ulcers. Consult your doctor to check your vitamin levels and consider supplementation if needed.
  5. Consider Dietary Supplements: Some studies suggest that taking supplements like L-lysine, an amino acid, might help prevent mouth ulcers. However, talk to your doctor before starting any new supplements.
