Chris Brown is magnetic. Or at least, his mouth is after he spent a lot to have some unusual dental work done.The singer has some new shiny gold grills -- 24 Karat gold covers all 28 of his teeth, according to Thomas Connelly, his celeb dentist -- but that's not what makes them special.Connelly claims it's the magnetic retention system. Breezy's back teeth have magnetic gold crowns embedded in them. This allows the grills to fit perfectly and lock in the magnets on his front teeth.CB's grills do not have any metal on the inside of his teeth, unlike conventional grills. This allows him to speak and sing normal while wearing them.It's obvious that dental work like this is expensive. We were told Brown's job cost was less than $100,000.
