Actress Alison Sweeney is teaming up with Crest Glide for the "Tight Spaces" challenge -- an initiative to encourage daily flossing.
The challenge also benefits "Feeding America," a domestic
hunger-relief charity. At the events held thus far in New York and Los Angeles, Sweeney encouraged participants to slide and glide through an obstacle course. Crest is donating $1 to the charity for
every participant with a guaranteed donation of $20,000.
Crest will also donate $1 for every person who tweets about the "tight spaces" in their life using the hashtag
#GlideTightSpaces.--Tanya Irwin
