New plastic pill to fight gum disease

New York -- Scientists in the US have developed a new plastic pill that can fight plaque and gum disease.

The tiny pill can relieve pain and swelling by just sitting between the threatened tooth and the diseased gum.

Researchers at State University of New Jersey, who have tested the pill on animals, said the plastic also serves as a barrier that enables the damaged gum and bone to not only heal but regenerate, says the online edition of BBC News.

Gum disease, or gingivitis, causes swelling and soreness of the gum tissue. Periodontal disease is when the infection becomes severe and involves supporting bones surrounding the teeth as well as the gums.

All gum disease is caused by the build-up of plaque. More teeth are lost through periodontal disease than through tooth decay.

"Human clinical trials of the pill may be two or more years away, depending on regulatory approvals," said lead researcher Mark Reynolds at the 232nd national meeting of the American Chemical Society in San Francisco.

The pill contains salicylic acid, the active ingredient in aspirin, for the swelling and discomfort and three antimicrobials to fight the infection.

Nigel Carter, chief executive of the British Dental Health Foundation, said a good dental routine, including brushing twice a day with fluoride toothpaste, flossing daily and visiting the dentist regularly, could treat and prevent periodontal disease.

"Smoking is also a major cause of gum disease as it increases the amount of plaque produced and starves the gums of oxygen - so if you smoke, give up," he added.
