He is an American actor who came to limelight when he played the lead role in a movie titled 'High School Musical' alongside his ex-girlfriend Vanessa Hudgens. At such a young age, Zac's smile was everything to his fans as he helped brighten up their day, but as he got older, he definitely saw the need to charm more fans with his smile and so, he resulted to a dental check to correct any issues.

Zac recently changed his dread looks, and he looks almost like when he starred in 'High School Musical'.
