Causes, treatment, and prevention of canker sores

If you've ever suffered from a canker sore, you know they can be painful and distracting. Today we'd like to share some information on how canker sores develop, how they can be treated, and how they're linked to your overall oral health. A canker sore is a type of mouth ulcer known medically as an aphthous ulcer. Aphthous ulcers are one of the most common complaints of the mouth, occurring at any age but being more likely in younger adults and in women. A first episode often occurs during adolescence, although children as young as 2 years have been known to develop canker sores. Between 20% and...

Liquid biopsy cancer test closer; dental offices ideal for screening

Dr. David Wong at the School of Dentistry at the University of California-Los Angeles (UCLA) has announced technology over a decade in the making is finally coming closer to implementation in everyday practices. Dr. Wong and his associates have been developing a method called "liquid biopsy," which detects circulating tumor DNA in bodily fluids such as saliva and blood. At the Annual Meeting of the American Association for the Advancement of Science (AAAS) in Washington, DC, Dr. Wong hosted a news briefing that outlined the prototype for liquid biopsy, which offers rapid, less invasive identification of cancers and easier tracking of disease progress during treatment. His device uses...

Breathing through mouth during sleep leads to tooth decay

A new study indicates that breathing through your mouth while  you sleep doesn't just put you at risk for snoring; it also leads to greater levels of tooth decay. Why is this the case? It has to do with saliva, acidity, and bacterial activation which are all impacted by mouth breathing. The team of researchers from the University of Otago in New Zealand published their findings in the Journal of Oral Rehabilitation. Part of the impetus for the study was a marked increase in dentists reporting patients complaining of dry mouth, especially during sleep or upon awakening. Dryness during sleep can be linked to other conditions such...

Scientists are now able to map oral bacteria

In dentistry, we often advise patients that brushing is important to "remove plaque and bacteria." We use the refrain so often that patients come to believe oral bacteria is bad and will inevitably lead to cavities. We consistently remind patients to floss in order to "remove bacteria and food particles between teeth" and to use a mouthwash that will eliminate oral bacteria. We forget, however, that we're referring only to bad bacteria and that there are a host of good bacteria also present in the mouth. Weight loss medicine has determined that gut bacteria has much to do with food absorption and metabolism. As researchers continue to...

Clinical practice guidelines for caring for restorations

As the United States population ages and we increasingly address the issues of tooth loss, repair, and replacement with better technologies, it's obvious that patients would need a standard of care for their long-term follow up. These restorations, dental implants, and permanent fixed dentures are, after all, often sold as "lifetime" solutions to tooth loss or injury.

And as of this month, University of Connecticut School of Dental Medicine's Dr. Avinash Bidra has the published the first national clinical practice guidelines for caring for patients with teeth restorations such as crowns, bridges, veneers and implants. While these procedures certainly aren't new, the first set...
