Mouth ulcers concerns

Mouth ulcers are painful sores that appear in the mouth, usually on the soft tissue - cheeks, lips or tongue. They can be white, red, yellow or grey in colour and swollen.

Although they're uncomfortable, mouth ulcers are usually harmless and clear up by themselves within a week or two.

In many cases, the reason for mouth ulcers is unclear, but triggers are thought to include:

  • Accidentally biting the inside of your cheek or a sharp tooth
  • Poorly fitting dentures
  • Hard food
  • A defective filling
  • Stress and anxiety
  • Hormonal changes – some women develop mouth ulcers during their monthly period
  • Eating certain foods – such as chocolate, spicy foods, coffee, peanuts, almonds, strawberries, cheese, tomatoes and wheat flour
  • Toothpaste containing sodium lauryl sulphate
  • Stopping smoking – when you first stop smoking, you may develop mouth ulcers
  • Viral infections – including the cold sore virus, chickenpox, and hand, foot and mouth disease
  • Medical conditions - including vitamin B12 or iron deficiency, Crohn's disease, coeliac disease, reactive arthritis, HIV, lupus, Behçet’s disease
  • Certain medications or medical treatments may also cause mouth ulcers

It's usually safe to treat mouth ulcers at home to help reduce swelling and ease any discomfort.

Self care

Tips for easing discomfort and aid healing…

  • Antimicrobial mouthwash or protective paste, available from your pharmacist
  • Use a soft toothbrush to brush your teeth
  • Use a toothpaste that doesn’t contain sodium lauryl sulphate, as this may be irritating
  • Avoid hard, spicy, salty, acidic or hot food and drink until the ulcer heals
  • Use a straw to drink cool drinks
  • Avoid things that may be triggering your mouth ulcers

Mouth ulcers can sometimes be a possible symptom of a more serious problem such as infection or mouth cancer. It's therefore essential that you contact Sturminster Dental Care as soon as possible if you notice:

  • Your mouth ulcer has lasted three or more weeks
  • You keep getting mouth ulcers
  • Your mouth ulcer becomes more painful or red

My wife and I visited Sturminster Dental Care today having been away from the area for some time and having had to use other dentists. The reception and treatment we received was outstanding. The reception team are kind, professional, and welcoming. Emmanuel ( our dentist) was truly exceptional, so skilled, gentle and supportive … simply second to none. Darren ( our hygienist) is equally brilliant and uses new and modern techniques which are much more effective and gentle on the gums and teeth. A really outstanding practice which we highly recommend. In addition their fees are very reasonable for the service they provide. Thank you.

I had never met the clinician before but he totally put me at ease. I was given the option of having the tooth extracted there and then or to wait for a later date.As I'm due to fly to Canada next week I opted to have treatment there and then. He was so gentle and explained each step of the process. Apart from the injection I did not feel anything - except relief when the tooth came out easily. I was given clear advice on what to do/not to do for the next 24 hours and to contact the surgery if I had any concerns. I am really grateful and pleased with the outcome ... no pun intended. :)

An excellent dental surgery. All the staff are friendly and helpful. Ian is an excellent dentist and Wendy is without doubt the best hygienist I have experienced. Everywhere from the moment you step in the door looks and feels clinically clean.

Helen the dental hygienist is a lovely lady and very very good at her job. She always introduces me to the nurse and does her best to make me feel comfortable and always advises me of what she is going to do. Helen really encouraged me to give up smoking. With her gently persuasive approach. She also advises me on how to clean my teeth better. Thank you Helen for your service. Keep doing what you do.
