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 High Street Dental Practice 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

From the welcome I received at reception through to the appointment itself all of the team at High Street Dental were delightful. During the treatment Samantha explained each step of the filling process and took real care in making sure I was comfortable throughout.

Great service, thorough explanation on teeth clenching and long term damage, backed up with evidence, as well as a guidance for myself and my children. 5 years dental nursing experience- by far this is the best dentist practice I have ever known.

The clinical staff are friendly and good at explaining the treatments and discussing how ordinary life (eating, drinking, tooth brushing, etc.) influence oral health

Kate has been my dentist since 2007 and I am comfortable and confident in her dealing appropriately with any dental issues I have had (and may have in the future!)

All of the staff are so polite and accommodating. The clinician team who saw myself and my son were amazing- they explained the care plan thoroughly and were so reassuring. In addition to this, they were so patient with my son and took time to get to know him and were so engaging and fun to enable him to have his check up! Thank you ☺️

The treatment was explained to my autistic child before he had it done in such a lovely way that he could understand and the dentist let him lead his treatment with conversation and kindness. This helped immensely with my child’s confidence and managed to get the treatment finished. Amazing as always.

Seen on time, greeted politely, all was explained what was going to happen, and I was put at ease and reassured. They kept checking if I was ok during my appointment.

Jas retiring was always going to represent a big change, and a tough act to follow, but I’m encouraged by Sam and team. The manner and quality of work has been great so far

31st March 2026

The friendliness and competence of the staff.

31st March 2026

Very friendly. They all put you at ease especially as a nervous patient. I couldn’t fault anything.

29th March 2026

The staff were all friendly, caring and informative. In particular the receptionist after my appointment showed great concern for my well-being as I was a little shaky. I was given time to sit down with a drink before leaving. I then received a call later to check I was alright. The care shown was much appreciated.

29th March 2026

Always made to feel very comfortable there. So would recommend to anyone who is nervous of dentists.Also the hygienist and the clinician explain everything very clearly and give great advice.Always easy to book the next appointment each time.
