A toothbrush is a very important part of any dental hygiene routine. Toothbrushes are key in removing plaque from the surface of your teeth, even in hard to reach areas. However, your toothbrush could also be key in causing illness and stimulating bacterial growth in your mouth, depending on how well you’re taking care of it. Germs are on every surface. They are always present. Your toothbrush is especially vulnerable to housing germs as it contains both the plaque from your teeth, and it typically rests in the least sanitary room in the house—the bathroom. Airborne germs from the toilet or unwashed hands touching items near your toothbrush could all be … Read more

Teeth Whitening Before you choose to have your teeth whitened it’s best to go and see your dentist first.

Dental Plaque May Trigger Blood Clots

by

Oral bacteria that escape into the bloodstream are able to cause blood clots and trigger life-threatening endocarditis. Streptococcus gordonii is a normal inhabitant of the mouth and contributes to plaque that forms on the surface of teeth. However, if these bacteria enter into the blood stream through bleeding gums they can start to wreak havoc by masquerading as human proteins. Researchers from the University of Bristol and the Royal College of Surgeons in Ireland (RCSI) have discovered that S. gordonii is able to produce a molecule on its surface that lets it mimic the human protein fibrinogen — a blood-clotting factor. This activates the platelets which then clump inside blood vessels. These unwanted blood clots will then encase the bacteria, protecting them from the immune system and from antibiotics that might be used to treat infection. Platelet clumping can lead to … Read more

Gum Disease More Common With Old Age

by

A recent study which appeared in Nature Immunology shows that the deterioration in gum health which occurs with increasing age is associated with a drop in the level of a chemical called Del-1. Periodontitis is a disease of the gums which causes bleeding and bone loss which can, over time, lead to loss of teeth. Periodontitis  is caused by an over-active immune response to bacteria that grow in the mouth. As people age they are more likely to suffer from inflammatory diseases, including gum disease. The new research investigated gum disease in young and old mice and found that an increase in gum disease in the older animals was accompanied by a drop in the level of Del-1. Del-1 is known to restrain the immune system by stopping white blood cells from sticking to and attacking mouth tissue. In mice that had … Read more
