Brief Summary:
The purpose of this study is to determine if an oral probiotic tablet taken once a day for twelve weeks can decrease the numbers of bacteria that are associated with tooth decay and gum disease in a dentally healthy, young adult population.

Condition or disease Intervention/treatment Phase
Oral Health Other: ProBiora3 mints Other: Placebo tablet Not Applicable

Detailed Description:
There are over 500 types of bacteria in the mouth. Most of these bacteria do not cause disease. However, some mouth bacteria can cause tooth decay and gum disease. The purpose of a probiotic tablet for the mouth is to put known healthy bacteria in the mouth. This study will compare the effect of the probiotic tablet on the levels of harmful or disease causing bacteria in the mouth to a placebo tablet that does not contain any probiotic bacteria.
