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

Reliable, professional, friendly

20th June 2026

All was explained perfectly. My welfare was paramount, always checking that I was OK. Some gum/teethg discomfort after the appointment but I expected that and it soon passed. Most certainly I will be happy to go back.

Very professional hygienist and her apprentice

14th June 2026

I have been registered with the Practice for 4 years and have always been cared for by Tracey. I am most disappointed to learn that she will be leaving in August. I would like to thank her for all the care and patience she has given to me since I came to the practice. Tracey is a kind, understanding and very talented dentist, who listens carefully to her patients before beginning any treatment. She is highly skilled and always conducts herself most professionally. Thank you Tracey.

Great dentist, friendly reception and nice waiting area

Brais ( sorry about the spelling!) knows I do not like going to the dentist from experience when I was young. I am also disabled and have just had a hip replacement. He and all the staff are so kind and put you at ease. Their professionalism is extremely high as is their standard of care. Having been in the medical profession for over 40 years I can’t but praise their patient care.

30th May 2026

For someone that hates going to the dentist all the staff here make the experience stress free. From my experience they always run on time which makes it stress free if I’m going to straight to work from my appointment. I can’t recommend them highly enough.

29th May 2026

I have been a customer for a few years at this dental practice and always will be they are very nice people as the staff

28th May 2026

Jay is always very patient with both of my boys who attended. He explains everything clearly and offers good advice on how they can look after their teeth better. He puts both of them at ease so that they have a good experience at the dentist. The reception team are also friendly and helpful. It is quick and easy to get booked in, and to book future appointments. It’s good to have the magazines in the waiting room (ones suitable for children too) although we didn’t need to wait long and were seen straight away at our appointment time.
