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 becomes more painful or red

Takes a lot for me to write a review but Best dentist I’ve ever been to. I hate injections and Jacqui made it absolutely painless. Very caring and thorough without feeling like they’re just doing things to rip you off. Exceptional in every way.

Both my wife and I have had great treatment from Temple Square dental. We have had the fortune to be treated by Prab and Aaron who are both very experienced and caring dentists. They’re backed up by a great team of supporting staff and receptionists. Only last week Rees on reception went to great lengths to fit me in for treatment on the same day. All in all we would highly recommended this dental practice.

I would recommend them to everyone I know. Bear in mind going to the dentist is expensive i found them reasonable for the amount of work my poor teeth need. Thank you guys.

Temple square has a very friendly team and makes you feel so welcome. My dentist always removers bits of formation about me which gives a personal touch and is always so helpful.

Being a patient for over 25 years with Temple Square, the staff know me, they are friendly and helpful, whilst remaining professional and polite. Despite moving to a different County, I would rather travel 3 hours there, and 3 hours back for an appointment with a great team and established rapport, than to source an available dentist nearer to where I live, and never find similar service.

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!
