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 Castle Park 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

Painless during treatment and no pain afterwards. All staff were absolutely lovely and very professional

17th April 2026

I saw Edward for my hygiene and check up. He is really friendly, listens and explains what he is doing at every step and also what his findings are. I have very sensitive teeth and am nervous about a hygiene appointment. But he used the airflow which was fine and also cleaned my teeth by hand as I don’t like the descaling tools. It was all round a good experience and I would recommend this Castle Park Dental care clinic

I trust Andrew the Dentist and Katie the hygienist they know their job, they are professional friendly and knowledgeable. The receptionist staff are equally as good. So are the staff supporting the dentist and hygienist. Toilets warm and clean

It's always a friendly environment and I don't have any issues and are comfortable attending my appointments.I do wish you would bring back the cherry flavour in the hygienist appointment though.

2nd April 2026

I am a very anxious patient and find all aspects of the dentist incredibly stressful. The care and patience shown by the reception staff and the hygienist team before, during and after treatment, despite my nerves and being tense, was excellent and the team really do try to put you at ease and reassure. Thank you.
