Scientists are working to create a simple, cost-effective saliva test to detect oral cancer, a breakthrough that would drastically improve screening and result in fewer people dying of the world’s sixth most common cancer.

A study reveals that gum deterioration, which often occurs with increasing age, is associated with a drop in the level of a protein called Del-1.

People who received frequent dental x-rays in the past have an increased risk of developing the most commonly diagnosed primary brain tumor in the United States. Ionizing radiation is the primary environmental risk factor for developing meningioma, which is the most frequently diagnosed primary brain tumor in the United States. Dental x-rays are the most common artificial source of exposure to ionizing radiation for individuals living in the United States.

New findings suggest that metformin may protect against oral cancer.

Oral bacteria that escape into the bloodstream are able to cause blood clots and trigger life-threatening endocarditis. Further research could lead to new drugs to tackle infective heart disease, say scientists.

Do you really want to avoid cavities in your teeth? Try massaging them with a high-fluoride toothpaste after lunch. “Rubbing toothpaste onto your teeth increases the fluoride protection by 400%,” say experts.

Receding gums often result in tooth sensitivity and can lead to decay of the root and persistent inflammation of the gum. New research demonstrates that a novel method using bovine collagen is able to enhance gum healing. This resulted in thicker margins around the tooth and, in over half the cases, complete coverage of exposed roots.

Japanese scientists have found that the odorous compound responsible for halitosis – otherwise known as bad breath – is ideal for harvesting stem cells taken from human dental pulp.

A novel bacterium, thought to be a common inhabitant of the oral cavity, has the potential to cause serious disease if it enters the bloodstream, according to a new study.

According to a new study, smoking causes the body to turn against its own helpful bacteria, leaving smokers more vulnerable to disease.
