Zac Efron

Once a High School Musical teen heartthrob, forever our #ManCrushMonday, Zac Efron's gappy smile has now been replaced with a gleaming Hollywood set. According to Insider, the Disney alum reportedly broke his jaw in 2013, when he slipped and fell and needed to get it wired shut - resulting in the need for cosmetic reconstruction.

Blake Lively 

Gossip Girl icon Blake Lively has always had naturally straight teeth, but no doubt gets her blinding smile topped up with bleaching treatments. It has been reported the star may have had some minor gum reshaping and bleaching, which can be done with a laser. 

Celine Dion

Instead of opting for porcelain veneers, Celine Dion kept the charm of her natural smile and instead added crowns to her incisors for a super straight set of gleaming teeth.

Morgan Freeman 

Oscar award-winning actor Morgan Freeman looked ten years younger after undergoing dental reconstruction to close the gap in his teeth and brighten his pearly whites. 

Kylie Jenner

There's no denying Kylie Jenner's smile transformation has influenced the rise of veneers. After getting porcelain veneers at the age of 18, Kylie swapped her baby-face smile for a symmetrical set fitted by Beverly Hills cosmetic dentist - Dr. Kevin Sands, DDS.
