Drake laughs off dental hygiene criticism: 'I have a pink diamond in my tooth'   Rapper Drake looks on prior to the International Champions Cup soccer match between Manchester City against Manchester United at NRG Stadium on July 20, 2017 in Houston, Texas. Rapper Drake has laughed off criticism about his dental hygiene, insisting a spec on his tooth in a recent photo was actually a pink diamond. The Hotline Bling hit maker posted a series of images from a night out on Instagram early on Friday, but one snap, in which he was featured smiling with an open mouth as he hugged a pal, caught the attention of a follower, who called Drake out for apparently missing a spot of food or other substance pictured on his front tooth.     “Lmao (laughing my a– off) all that money and ur (sic) teeth don’t look clean,” the Internet troll wrote.   The hip-hop star quickly responded to the detractor, making it clear he takes good care of his grill, even revealing he’s jumped on the trend of using activated charcoal as a natural teeth whitener. “I have a pink diamond in my tooth,” he replied. “I brush with activated charcoal before any club night where I will see baddies (hot women) know dattttttttttt (sic).”Interesting news from Dr Joe Miskin, Ajax Drjoemiskin.com
