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 Lynn Road 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

Welcoming reception staff and easy to complete and sign form. Short waiting time for appointment. Sarah Gauvin, the hygienist was attentive and listened to my needs. She was gentle and thorough and has made my smile so much better. She doesn’t rush and gives her patients the time and attention they need when attending a dentist appointment. Thank you

I have been attending Lynn Practice since 2013? I always have confidence in Dr Joshi and the receptionists. They have been very good to me as I have suffered with abscesses over the years and they have always been able to get me an appointment as they know I panic!!! I am never late for an appointment but unfortunately was an hour late this time, although I was happy to re-arrange as did not want other patients to be delayed, Dr Joshi was able to see me. The hygienist could not see me till 2.00 so was going to re-arrange, but whilst seeing Dr Joshi one of their other hygienist became free and was able to see here. I have now booked to see her in my next appointment as my original hygienist has retired. I was very grateful to one an all. Thank you.

I am highly impressed with this dental practice! The staff members are consistently friendly, kind, and exceptionally helpful. Dr. Muhannad Alif has gone above and beyond for me, and I cannot thank him enough for his outstanding care. I wholeheartedly recommend this exceptional team to everyone!I visited (Smile Dental Clinic kings Lynn )and the doctor spent a mere 2 minutes checking my teeth. I am extremely dissatisfied with the level of care I received. I experienced significant pain that kept me awake at night, yet the doctor failed to provide any painkillers or medication. This is unacceptable.thank you Lynn road dental practice kings Lynn.

After a few days of acute pain, I decided to consult a dentist. Fortunately, I was able to be seen the next day. Everything was explained to me in great detail, although I'd carried out some of my own 'research' beforehand. The immediate pain was identified and dealt with swiftly. It would be fair to say I'm amongst many who fear the dentist. Although that fear is at the back of my mind, I'd highly recommend this friendly bunch of professionals.

A very warm welcome on arrival. My dentist is always professional and considerate. Listening to me and answering my questions. My hygienist is really careful and respectful of my needs during treatment.
