No more mouth ulcer misery

If you have ever experienced a mouth ulcer, you know a little sore in the wrong place can be a big pain. Here’s some expert advice to help prevent mouth ulcer misery, from Dirna Grobbelaar, Ivohealth’s Oral Hygiene Advisor.

What is a Mouth Ulcer?

Mouth ulcers, also known as canker sores, are usually round and reddish in appearance and only appear inside the mouth, on the tongue or around the mouth’s lining. If it’s on the outside of the mouth or on the lips it’s more likely to be a cold sore (fever blister).

Causes of Mouth Ulcers

Most people will experience a sore inside the mouth at some point. These are often caused by a minor injury – biting the cheek accidentally, consuming food or drink that’s too hot, poorly-fitting dentures or braces, especially when orthodontics are initially fitted.

Aphthous mouth ulcers are the ones that recur and often first appear in childhood or adolescence. They tend to return during hormonal changes, stress or any time that the immune system is compromised. Ulcers can also be caused by allergies, viruses, nutritional deficiencies and conditions like coeliac disease.

 Treatment for Mouth Ulcers

Mouth ulcers are not contagious and usually clear up by themselves in a few days. Keeping the mouth clean with a proper oral hygiene routine should help them heal more quickly.

Various over-the-counter medications can relieve pain and discomfort. Soothing Aloclair gel and spray are easy to apply and help form a barrier over the exposed nerve endings, giving almost immediate relief.

Mouth ulcers tend to last up to 10 to 14 days. Consult your doctor or dentist if your ulcer does not heal within three weeks. Oral cancer is predicted to treble in the next generation and it’s important to rule this out.

Five tips to manage mouth ulcers

  1. Avoid very hot, spicy, salty or acidic foods and drink
  2. Use Aloclair gel or spray to form a protective barrier over the ulcer
  3. Use a straw when drinking
  4. Rinse with an alcohol-free antiseptic mouthrinse such as GUM Paroex
  5. Maintain a good oral hygiene routine using a small, soft-bristled toothbrush
