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? […]

Study findings underscore the importance of good oral health in blood pressure control and its role in preventing the adverse cardiovascular effects known to stem from untreated hypertension. […]

An unhealthy population of microbes in the mouth triggers specialized immune cells that inflame and destroy tissues, leading to the type of bone loss associated with a severe form of gum disease, according to a new study in mice and humans. The findings could have implications for new treatment approaches for the condition. […]

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. […]

What is Dental Amalgam (Silver Fillings)?   Most people recognize dental amalgams as silver fillings. Dental amalgam is a mixture of mercury, silver, tin and copper. Mercury, which makes up about 50 percent of the compound, is used to bind the metals together and to provide a strong, hard, durable filling. After years of research, mercury has been found to be the only eleme... […]

Orofacial pain includes a number of clinical problems involving the chewing (masticatory) muscles or temporomandibular joint.

In our fast-paced lives, many of us may be eating in a hurry, taking giant bites of our food to get done quickly and on to the next task. Fast-food restaurants advertise giant burgers and sandwiches as a selling point, but often those super-sized delicacies are larger than a human mouth.   Taking bites that are too big to chew could be bad for your jaw and teeth, says the Academy of Genera...

The History of Dental Advances   Many of the most common dental tools were used as early as the Stone Age. Thankfully, technology and continuing education have made going to the dentist a much more pleasant – and painless – experience. Here is a look at the history of dentistry's most common tools, and how they came to be vital components of our oral health care needs.   Where did t... […]

Dry socket, the most common postoperative complication from tooth extractions, delays the normal healing process and results when the newly formed blood clot in the extraction site does not form correctly or is prematurely lost. This blood clot lays the foundation for new tissue and bone to develop over a two-month healing process.   Updated: October 2008   &nbs […]

If you experience frequent headaches and pain in your lower jaw, check your posture and consult your dentist about temporomandibular disorder (TMD), recommends the Academy of General Dentistry (AGD), an organization of general dentists dedicated to continuing dental education.   Poor posture places the spine in a position that causes stress to the jaw joint. When people slouch or hunch over... […]

Start by Visiting the Dentist   An online poll of 289 general dentists and consumers confirms the traditional stereotype that men are less likely to visit the dentist than their female counterparts, according to the Academy of General Dentistry (AGD), an organization of general dentists dedicated to continuing dental education.   Why? Nearly 45 percent... […]

Why is Oral Health Important for Men?   Men are less likely than women to take care of their physical health and, according to surveys and studies, their oral health is equally ignored. Good oral health recently has been linked with longevity. Yet, one of the most common factors associated with infrequent dental checkups is just being male. Men are less likely than women to seek preventive ... […]

What is Baby Bottle Tooth Decay?   Baby bottle tooth decay is caused by the frequent and long-term exposure of a child's teeth to liquids containing sugars. Among these liquids are milk, formula, fruit juice, sodas and other sweetened drinks. The sugars in these liquids pool around the infant's teeth and gums, feeding the bacteria in plaque. Every time a child consumes a sugary liquid, acid... […]

Pacifiers Have Negative and Positive Effects   It’s one of the hardest habits to break and can require a great deal of persuasion: Parents often struggle with weaning their child off of a pacifier.   There is much debate regarding the use of pacifiers, but there is evidence to show that there are both pros and cons, according to a study in the January/February 2007 issue of Gene...
