Do you have bad breath?
If yes, you may be eligible for a new study! The Forsyth Institute Research Clinic is conducting a study testing rinses and bites containing natural fruit extracts for bad breath.


We are inviting volunteers (18 years old and older) experiencing bad breath (also known as morning breath or halitosis) to participate in a 7-week study to test new (investigational) products in reducing tongue bacteria-related with bad breath.

Where: The Forsyth Institute Center for Clinical and Translational Research, 245 First Street, 17th Floor, Cambridge MA (Enter on 1 Athenaeum St.)

Screening Visit


• People with existing bad breath are asked to come for an eligibility visit: a
routine exam for gums and assessment of bad breath will be done.

test products (2 rinses and 2 bites) and seen at 7 weekly visits.
• All visits will be scheduled in the morning hours (8 am- 11:30 am)
