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

It has taken me years to find the right dentist/practice and right from my first appointment I knew that I had finally found the one that I could completely trust and feel confident with. Thank you to all the staff that have finally built up my trust and confidence and now I am having treatment to make my teeth look better!

Edward the hygienist is really good. He explained everything that he was doing to me. He and the assistant were both very professional and lovely.

30th June 2025

I missed my appointment and was contacted by the practice. I live nearby, so they rescheduled it from 16.45 to 17.10 and stayed behind to complete the work as I was going on holiday shortly after.I apologized profusely, but they could not have been kinder, nor more welcoming. It is only when things go wrong that you can truly judge the level of service; which was excellent in terms of reception and outcome!

I was very nervous and Simon was very understanding and put me at ease. He was so professional I didn’t even realise the tooth had come out. Also the experience of the injection was far better than I have experienced before.

I use them regularly, I am always satisfied. I am disabled, they do not rush me, they make me comfortable, they do what they can to accommodate me.

13th June 2025

Appointment was broadly on time. I received a quick overview of what was to happen. After the inspection a detailed discussion on treatment options (2) took place and a way forward was agreed. Can’t ask for more.

12th June 2025

Edward is the best ever hygienist, he is very knowledgeable and explains everything in an understandable way. I feel completely confident in him. I am also fortunate to have Andrew as my dentist, he’s a lovely guy but also very professional and a whizz at his job.

I was really happy that my broken filling could be fixed, and without an additional visit. Simon has done a really good job. He checked in with me throughout, giving options and making sure I was happy with the outcome. The resulting filling is smooth and feels good. Thank you!

5th June 2025

The welcome from the Reception staff is always warm and friendly. Edward the Hygienist was very patient when I twice had a coughing fit during the clean. Andrew may Dentist was very welcoming and attentive as always. I have great faith in his advice and skill. The Dental Nurses Chloe and Adriana both had welcoming smiles.
