A former drug addict has undergone a drastic makeover after being given a new set a teeth.

Brittany Negler, of Philadelphia, in the US, went down a “dark path” after the death of her 18-year-old brother – turning to drugs to help numb the pain.

As a result of her addiction, the 29-year-old suffered damage to her teeth, including losing a few gnashers and sustaining rotting in others.
