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 Lynn Road Dental Practice 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

I can't recommend Mo and assistant Kerry enough..im so happy

I've been a patient with your surgery for around 7 years and have only had positive experiences. This particular appointment was to have a wisdom tooth removed. My dentist is fabulous. He knew I was nervous and between him and the dental nurse, they went out of their way to help me relax. My nerves came from a previous experience with a different dental practice and this experience was completely different. I felt no pain, and it was calm all the way through.

4th November 2025

The treatment that I received and always receive is exemplary. I feel comfortable with my dentist and hygienist, the support staff are excellent, always taking into account my specific needs and time constraints without any stress.

Shirley is my new hygienist at the practice after being with Debbie for quite few years. I can honestly say I was really impressed and felt at ease straight away. Shirley is very experienced and very informative in all that did. Really happy with her treatment and very happy she is my new hygienist after leaving Debbie as they are both really nice and great at there work. Paul McCarthy Snettisham Norfolk
