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…

  • 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 [practice name] 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

Based on my experience with other dental practices here in the UK, I can confidently say that this is the best dental practice I have visited. The quality of care and service is excellent, the staff are always friendly and welcoming, and the practice is exceptionally clean and well maintained. This is why I felt it genuinely deserved such high ratings.

Dr Aaron treated my daughter 11 y.o with calm, professional respect. He understood her anxiety and took time to reassure her. The extraction went very smoothly and it was very quick. Recovery had no issues. Dr Aaron is amazing very caring dentist!

I enjoy my six monthly check ups at Temple Square Dental. The staff are all friendly and reassuring and the dental work I have needed over the last 23 years has been carried out professionally and painlessly. Because of the biennial care I receive, my teeth and gums remain healthy in spite of 80 years of wear and tear! Many thanks to Aaron and Natalie and Lucie.

I am an extremely nervous patient and have neglected my dental health due to this. The team have been wonderful and kind in their treatment of me, have treated me with dignity and without judgement and made facing my phobia as easy for me as it could be

I was given an emergency appointment as I was in pain. A receptionist called Amber proved extremely helpful following my assessment she arranged a second emergency appointment to allow me to complete my treatment rather than wait several days in continuing pain. She demonstrated initiative , concern and excellent communication skills. My clinical care was excellent as usual but Amber facilitated my treatment to avoid delay . A really good experience .

The hygienist Joy, and her assistant delivered a very comfortable, thorough and highly professional experience. This was my first encounter with this clinician and she was very communicative throughout. I would highly recommend her services.

Very professional team. They explained what was would happen at each stage. Made me feel relaxed and the whole procedure completed without any discomfort. On completion they went through the post procedure process so I knew exactly what to expect/do.

I cannot recommend Becky Pilgrim enough! I have just completed my invaslign treatment and she has been absolutely brilliant. She is a true professional and a perfectionist- which is just what you need for a smile makeover! I have been amazed by the results and this has been a well worthwhile investment. Becky is a very knowledgeable practitioner and I will be wholeheartedly recommending her to others. In addition, Thank you to all the staff at Temple Square Dental who have always been welcoming and have gone above and beyond with any of my queries. Thank you all once again!!! If I could give 10 stars I would!!!!

My son who is on the autism spectrum was with this dentist practice and the dentist he saw was perfection she listened, took her time and made every effort to make sure my son was comfortable and understood everything she was doing at every stage and spoke to him directly instead of through myself which I respect massively as they shouldn’t be treated differently, we unfortunately moved dentist through location being too far out for us otherwise I would of stayed with them 1000000%

Very friendly and good service. Kind and caring treatment which was well explained and executed. Thanks.

All staff are extremely friendly, and thorough with what they do. My 5 year old has seen Dr Morgan and now Dr Lakin for her regular check ups and have been fantastic! They both have had such a calm approach and have been so gentle. Checks are thorough and I love that they have both communicated with me during the check ups so I understand what’s happening. Advice is sound and clear, and it’s an overall pleasant experience.
