Seaweed ...A New Weapon Against Plaque
Every so often, a new plaque-fighting tool catches our eye at Wilmette Dental. Now, from the UK, comes news of an enzyme found on the surface of seaweed that shows great promise in reducing the bacteria that form plaque on teeth. In fact, researchers are so hopeful about the find, that they believe the seaweed enzyme may one day be a key ingredient in oral hygiene products.
The enzyme was originally identified by an English marine research group screening for compounds that could break up microbes from the surfaces of ship hulls. The concept of a dispersing microbe caught the attention of Newcastle University's School of Dental Sciences, which recognized the potential for using the natural enzyme to break up the bacteria that causes plaque on teeth. Oral bacteria form plaque by “colonizing” on teeth -- a sort of attack by numbers. The bacteria create a slimy, tooth decay-causing film of extracellular DNA that joins them together and helps them stick to a solid surface -- our teeth. The seaweed enzyme prevents these nasty microbes from grouping in the first place by breaking up their DNA, and that helps prevent the formation of plaque.
More research needs to be done to confirm the seaweed enzyme’s effectiveness, and to ensure that it is safe for human use. If so, researchers hope to use the enzyme as an ingredient in toothpaste, mouthwash and denture cleaning products. And, scientists say the enzyme may be used in other healthcare areas, such as keeping certain medical implants clean.
