London dental patients have been seen by the local London dentistry for problems dealing with ulcers or more commonly, canker sores. These ulcers are simply open sores in the mouth and can be caused by a variety of reasons. They appear as a white sore in the mouth. You can not pass an ulcer on to someone else as they are not contagious.
Causes of mouth ulcers include injuries sustained by bighting the cheek of tongue, an allergic reaction to something, an immune system response to some outside agent to include chemicals, large amounts of stress, a B12, iron, or folic acid deficiency in the diet, using mouthwash or toothpaste with SLS in it, viral infections related to herpes simplex or the foot and mouth disease, Han, problems with the intestines, and cancer of the mouth.
The lining of the mouth is opened due to one of the problems listed above and bacteria gets inside. The toxins from the bacteria are released and the cells around the ulcer are killed. This is the reason some ulcers get larger and hurt much more. If you find you have an ulcer, you need to see your doctor, if it does not go away within a week or two or if it starts hurting more. Ulcers that do not go away within a month could be mouth cancer in rare instances.
Simple mouth ulcers can be treated with a warm salt water gargle, using a teething gel for the pain, carmellose gelatin paste over the ulcer as a protective covering, and Paracetamol. Treatment should need no more than a week to heal the ulcer. If it does not, a trip to the dentist is necessary.

According to the British Dental Health Foundation, there are around 4,750 new cases of mouth cancer being diagnosed every year in the UK. The incidence of this disease has been observed to increase by at least 30 percent in the last decade. It is further estimated to cause an annual mortality of about 1600 people.That is quite alarming as you can see. Tobacco users and alcohol drinkers are more at risk of developing mouth cancer. And for those who smoke and drink at the same time, the risk is even heightened up to thirty times more.

A few months ago, the foundation launched its Mouth Cancer Awareness Week campaign at the House of Commons in London. The foundation was very enthusiastic about the results of a study which was published on the international scientific journal Cancer Research in September, 2007.

The study which was conducted at the University of Hong Kong found that lupeol, a compound found in fruits such as blueberries, papaya, blackberries, grapes, mangoes, and strawberries, seems to be very effective in preventing the growth of mouth cancer cells.

Anthony Yuen, a professor at the University of Hong Kong’s surgery department said of the lupeol compound, “It can suppress the movement of cancer cells and suppress their growth and it is found to be even more effective than conventional drugs (eg. cisplatin).” He further said that lupeol is even more effective if combined with chemotherapy drugs and has but a few side effects.
Lupeol acts to inhibit the NFkB, a natural protein that promotes cell growth and repair. As this protein is found to be activated in many cancers, Yuen hopes that lupeol may find its use in these other NFkB-dependent cancers as well.
