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 The Mayhill Dental and Specialist Centre 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

Incredible team at the Mayhill. My husband has a phobia of dentists and needed two teeth removed. The reception team were kind and helpful , we saw Dr Ryan Lello who is a very skilled dental surgeon . He extracted both teeth with no pain and no trauma . He was also very reassuring for a nervous patient. I would 100% recommend Ryan and Mayhill dental practice

Rapid emergency appointment. Fitted me in quickly. Extremely helpful and friendly receptionist and dental nurse / dentist. The dentist (not my usual dentist) took care to assess my specific situation, explain the required treatment and then fixed the issue very efficiently, whilst being very considerate of my comfort / any pain I may experience.

Everyone at the Mayhill centre have provided me with excellent care following an accident causing a broken front tooth. I was an extremely nervous patient when I arrived a few months ago. Ellen and the reception team scheduled a very prompt appointment to be seen initially and greeted me with care and compassion. Nick saw me quickly and was thorough in his examination. I was provided with clear information regarding a treatment options and was treated with kindness throughout, easing my anxiety. At every stage, great care has been taken to ensure the best result possible. David provided root canal treatment, ensured every step was clearly explained and was very gentle. Jason provided treatment with a crown and paid incredible attention to detail, ensuring the shape and colour matched my own teeth- I am so pleased with the result. The dental nurses, Emily, Kacey and Remmie, were also kind and made me feel at ease through the process. I cannot recommend Mayhill enough. Everyone there has helped to not only ensure my broken tooth has restored with the best possible outcome but also make a very nervous patient feel comfortable and well cared for. I am grateful to all of the team.

I have had the same Clinician for years which is positive as they know me and provide consistent expertise. The process of the filling was very quick and my Clinician was helpful and knowledgeable providing a good overall experience.
