Researchers developed a new device that ameliorates the characteristic vocal and motor tics of Tourette syndrome. By biting down on the simple, removable oral splint, both adults and children with Tourette syndrome experienced a reduction in their tics. The action of biting down on the oral splint could serve as a sensory trick; sensory tricks are known to ameliorate motor symptoms in cervical dystonia. The device might be particularly effective in children.

Mythbuster: The idea that bacterial collaborations within microbiomes, like in the mouth, have evolved to be generous and exclusive very much appears to be wrong. In an extensive experiment, lavish collaborations ensued between random microbes. And some bacteria from the same microbiome were stingy with one another.

The team also has developed an adhesive that's 30 percent stronger after six months in use than adhesives that are currently used to keep fillings in place.

Researchers have determined how a type of bacteria commonly found in the mouth accelerates the growth of colon cancer.

Most reptiles and fish have multiple sets of teeth during their lifetime. However, most mammals, such as humans, have only one set of replacement teeth and some mammals, like mice, have only a single set with no replacement. This diversity raises both evolutionary questions -- how did different tooth replacement strategies evolve? -- and developmental ones -- which mechanisms prevent replacement teeth in animals that lost them?

A new study in mice reveals that omega-3s, a type of fat found in fish oil, reduces fetal and neonatal deaths, suggesting they could prevent some miscarriages in women.

New science uncovers how an unlikely culprit, Porphyromonas gingivalis (Pg) -- the bacterium commonly associated with chronic gum disease -- appears to drive Alzheimer's disease (AD) pathology.

When the good and bad bacteria in our mouth become imbalanced, the bad bacteria form a biofilm (aka plaque), which can cause cavities, and if left untreated over time, can lead to cardiovascular and other inflammatory diseases like diabetes and bacterial pneumonia. A team of researchers has recently devised a practical nanotechnology-based method for detecting and treating the harmful bacteria that cause plaque and lead to tooth decay and other detrimental conditions.

Elderly individuals with fewer teeth, poor dental hygiene, and more cavities constantly ingest more dysbiotic microbiota, which could be harmful to their respiratory health, according to new research. The findings come from a large, population-based study that identified variations in the tongue microbiota among community-dwelling elderly adults in Japan.

Getting wisdom teeth removed may be a rite of passage for many teens and young adults, but the opioid painkiller prescriptions that many receive could set them on a path to long-term opioid use, a new study finds. Young people ages 13 to 30 who filled an opioid prescription immediately before or after they had their wisdom teeth out were nearly 2.7 times as likely as peers to still be filling opioid prescriptions months later.

Little is know about the bacteria Streptococcus sobrinus, which accelerates tooth decay in some people. This will soon change because a team of researchers has now successfully sequenced the complete genomes of three strains of S. sobrinus.
