Lindsay Lohan can now smile without any reservations.

E! Online reports the 25-year-old actress displayed her new pearly white teeth, thanks to the Zoom whitening system, on her WhoSay page on Saturday.

Thanks to Dr. Dorfman for the zoom, Lohan wrote underneath a photo of her posing and smiling. My gums are so sore though!

This is a drastic difference from a couple of weeks ago when the Mean Girls star was spotted on the red carpet at the premiere of THQs Saints Row: The Third with yellow stained and possibly decaying teeth.

She joins a list of Dorfmans high-profile clients including Jessica Simpson, Anne Hathaway, and Usher.

Lohan recently flashed her new bright smile at a concert celebrating the 10th anniversary of former President Bill Clintons foundation.

However, its debatable whether we will see more of her pearly whites in the near future.

Lohan is set to appear in court on Wednesday to find out whether she will face jail time for violating the terms of her probation in her jewelry theft case.
