The British Dental Health Foundation's National Smile Month, the U.K.'s biggest oral health campaign, has begun and runs through June 20.
Nearly 2,500 organizations are taking part in the campaign that has a single icon this year, the "smiley." It will be featured on local dental practices, education centers, shopping centers, and sports teams.
The campaign has the backing of platinum sponsors Listerine, Oral-B, and Wrigley. Philips, Lloyds Pharmacy, Argos, Invisalign, Bupa, NUK, and Denplan also are supporting this year's campaign. Details of events are at smilemonth.org.
