Mouth ulcers are normally small, painful white lesions or open sores that can develop anywhere in your mouth or at the base of your gums. They can make eating, drinking and talking very uncomfortable.
Mouth ulcers most often appear as a result of an injury.
Causes include biting lips or tongue, sometimes after dental work when the local anaesthetic hasn’t worn off and the mouth is still numb.
Hot foods like, pizzas can burn the soft tissues in the mouth causing an ulcer. Some people acquire white ulcers from acidic foods, like, many fruits, lemon juice, vinegar and tomatoes.
Mouth ulcers usually disappear within 2-3 weeks. If they persist for longer consult with your dentist.
