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

The dentist is always very kind. I have acid reflux and cannot have the chair very reclined. I have to swallow frequently. He always stops whenever I need to do this. He explains in detail what treatment he recommends and is always kind and considerate.

A warm welcome from reception staff , cheerful waiting room . Positive approach from the Dentist with constructive advice and encouragement and not least conscientious assistance from Dental Nurse . I have been a patient here for some fifteen years and the practice scores highly in relation to previous experience elsewhere.

31st March 2025

I had a visit to the hygienist who was friendly and I explained that I had to reschedule my appointment because I had a severe attack of neuralgia which meant that I could not attend the original appointment. She was very understanding and advised me of various aids and procedures I could use to help with the hygiene of my teeth and gums

Khem Joshis is my Dentist, after a bad experience previously with another dentist, Khem has made me less fearful of going. There's no judgement and he makes my visit calm and reassuring.

The efficient of the reception team, booking the appointment, I think her name was Gemma. The dentist and his nurse was both lovely and kind.

Very friendly practice. It was the first time I’d seen Mo - he was great.

After a long period of unsettlement regarding the treatment I had previously received, Mo has given me confidence from the offset to hopefully resolve my tooth pain.
