While effective at warding off ghosts and wilting poisonous flowers at will, bad breath hinders most other daily tasks. Ensure eloquent exhalations with today's Groupon: for $89, you get an in-office fresh-breath treatment and take-home kit at The Brand Wellness Center (a $295 value).

The Brand Wellness Center draws on more than 30 years of experience to forward a preventative, holistic oral-health philosophy. One of The Brand Wellness Center's dental detectives will conduct a comprehensive evaluation to isolate the root cause of bad breath and determine whether odor problems stem from the mouth, sinuses, digestive system, or forgotten slice of limburger in the wallet. After assessing the patient's condition and making any necessary diet-change recommendations, technicians swab the mouth with a natural toothpaste rinse, gel, and brushing. Clients continue the fight against worrisome mouth winds with a take-home kit of gel rinse and toothpaste.
