Mouth Ulcers

What is a Mouth Ulcer?


Mouth ulcers are very common; usually triggered by stress and clear up on their own within 1-2 weeks. They are known as; mouth ulcers, aphthous ulcers or canker sores. They are different from cold sores as they are non-contagious and are not associated with the herpes virus. Rarely are a sign of something serious but maybe uncomfortable to live with.


What causes Mouth Ulcers?


Fixed braces, rough or sharp teeth, fillings and rubbing dentures could be associated with the development of mouth ulcers, as well as food intolerance and allergies. They can be also traumatic in aetiology; hard, crusty food or burn from food or drinks. Systemic, underlying medical conditions like Crohn’s disease or Vitamin deficiencies (B12) could also trigger recurrent oral ulcerations. A blood test should be considered to assess the levels of Vitamin B12, Iron, Zinc as well as a full blood count. Ingredients from ordinary toothpastes can trigger mouth ulcers. SLS (Sodium Lauryl Sulfate) is included in several toothpastes widely available; its sole purpose is foaming while brushing, giving the impression of cleaning your teeth while actually it doesn’t. SLS has been related to the development of mouth ulcers. We would advise SLS free toothpaste especially to individuals with a tendency to mouth ulcerations. You should allow a week, before you see any difference, following change of your toothpaste. Tiredness, anxiety and stress could also be associated with the development of mouth ulcers, management of the above is key.


What should I do in case that I have a Mouth Ulcer?


Keep your mouth clean; clean oral cavity would minimise the risk of an ulcer getting infected. Use regular warm salty mouthrinses, avoid acidic or spicy foods. Corticosteroid lozenges, antimicrobials such as Gingigel, Corsodyl or Curasept usually speed up healing and prevent from an infection of the ulcer. Best applied before bed and in gel form. Painkillers can be used; mouthwashes, gels or sprays as needed.


Mouth Ulcers that haven’t healed in three weeks MUST be checked by your Dentist.
