Arms Assigned Interventions
Active Comparator: Probiotic tablet Other: ProBiora3 mints
Probiotic mint tablet taken once daily for 12 weeks containing ProBiora3, a combination of three known healthy bacteria
Other Names:
  • EvoraPlus
  • EvoraPro
Placebo Comparator: Placebo tablet

Other: Placebo tablet
Mint tablet taken once daily for 12 weeks without the ProBiora3 combination of three known healthy bacteria
Other Name: placebo

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.
