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 Green Park Dental 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

All very friendly

25th July 2026

Really happy for the extra level of treatment I received, not only was the cleaning treatment very efficient but was less painful than previous times and I asked whether the water was warm and told yes their new system gently warms the water. I was given a special paste tooth rub which would identify any plaque which would turn pink. I was also given x rays to try to identify what was causing a random ache in one of my back teeth. In addition I was also given a prescription for both dry mouth and some fluoride toothpaste . Thanks

Congratulations and well done to Dr Aarifa Hussain for her bravery . I would like to thank Dr Aarifa Hussain for her exceptional care during my tooth extraction. She was confident, professional, and reassuring throughout the procedure.Her courage and expertise helped put me at ease, and I am very grateful for the excellent treatment I received. I visited other dental clinic in London and they were scared to remove my tooth and was referred to a specialist but Dr Aarifa Hussain took the initiative and assured me that she will do it which is a real daring and challenging for Aarifa . Great achievement , inspiration and hats off . I would like to thank Nurse Anne too for her support and care . I was welcomed by the Receptionist , sorry dont know the name and all the staff very friendly and would definitely recommend my friends to visit the lovely Green Park Dental Practice in Bath

The clinicians and other staff are very kind and we’re all extremely helpful and kind when I was going through cancer treatment. The clinicians spent time carefully explaining treatment options and showed me x-rays. The hygienist carefully explained areas to focus on to prevent future problems.
