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 healin…

  • 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 [practice name] 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

Lovely friendly staff

I am a very nervous and frightened patient. The procedure I had today was long an unpleasant for me. However the support I received from Marcus, Molly and also the receptionist was fabulous. It could have turned out to be a lot more traumatic for me if it wasn't for the compassionate and skilled team. Thank you for doing everything you could to put me at ease! I would very much recommend this practise for anyone who is nervous or fearful.

The friendliness of the staff

16th July 2025

My appointment was for a check up and cleaning. The dentist advised me that there was a new and less invasive procedure for teeth cleaning which I would find to be much easier to deal with.It took far less time and was far more comfortable than previously. The dentist talked to me all the time and it gave me lots of encouragement and I felt far happier than on past visits for hygiene treatment.I am very happy with my dentist and would definitely recommend him to friends.

Calming influence of all staff as im a nervous patient

Being allocated appropriate time for the hygienist to do her work to the highest standard. Dealing with an educated person that properly explains the procedures and my progress towards healthy teeth and gums.
