Patch May Help Heal Canker Sores

Patch Tames Inflammation With Licorice Extract

March 22, 2007 -- A new over-the-counter patch may help canker sores heal faster.

Scientists (including the patch's inventor) announced that news today in New Orleans at the 85th general session of the International Association for Dental Research.

The researchers studied 46 adults with recurrent canker sores, also called recurrent aphthous ulcers.

Half of the patients received the patches, called Cankermelts, which the researchers say contain licorice extract to curb inflammation. Those patients were told to put the herbal patch over their canker sore for 16 hours per day but not to wear the patches while sleeping.

For comparison, the other patients didn't get the patches and agreed not to use any other canker sore treatment.


Every day for eight days, the patients rated their canker sore pain and got their canker sores photographed and checked by the researchers.

Before treatment, the patients' average canker sore pain and average canker sore size was similar for both groups.

But by the end of the eight-day study, the patients who wore the canker sore patches had less canker sore pain and smaller canker sores than the untreated group.

The researchers included scientists from the University of Washington, the American Academy of Oral Medicine in Seattle, and Jeff Haley, founder and chief scientist of Orahealth, the company that makes Cankermelts.

Only 18.5% of Americans never floss. You are missing out on a simple way to make a big difference in the health of your mouth. Regardless of how well you brush, plaque still forms between your teeth and along your gums. Floss removes food trapped between the teeth and removes the film of bacteria that forms there before it turns to plaque, which can cause inflamed gums (gingivitis), cavities, and tooth loss. Try flossing just one tooth to get started.

You are one of 31% of Americans who don't floss daily. You are missing out on a simple way to make a big difference in the health of your mouth. Regardless of how well you brush, plaque still forms between your teeth and along your gums. Toothbrush bristles alone cannot clean effectively between these tight spaces. Flossing removes up to 80% of the film that hardens to plaque, which can cause inflamed gums (gingivitis), cavities, and tooth loss. Aim for 3 more days!
