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 healin…

The team are NUL Dental Practice are all incredibly polite and professional. I was recently moved in to the care of Dr Marcus Charles-Drummond which, as anyone who has had to switch dentists knows, can be a little nerve wracking. However Marcus is incredibly thorough, fast working, informative and makes you feel comfortable with the procedure you'll be undergoing. Recently had to have two fillings plus an extraction and Marcus and Cass were both wonderful. Couldn't recommend enough. You'll be in good hands with this Dental practice

My wife and I have been with the practice for several years and always found the service to be excellent. Emma and her reception colleagues are friendly and make you feel welcome. My recent appointments have been with Dr Marcus, and dental nurse Molly and both have been excellent. They are professional, friendly, and attentive with exceptional client care. Marcus took the time to explain everything clearly and in detail, concisely discussing options for treatment. I am really happy with the treatment received, and would recommend without hesitation if you are looking for a private dental practice.
