Lindsay Lohan showed off her new pearly whites over the weekend, just two weeks after drawing attention for her seemingly decaying teeth.

"Thanks Dr. Dorfman for the zoom," the 25-year-old actress wrote underneath the picture of her teeth, which she posted on the whosay site. "My gums are so sore though!"

Is something wrong with Lindsay Lohan's teeth?

Dorfman is a high-profile Los Angeles-based dentist who has worked with celebrities such as Eva Longoria, Jessica Simpson, Anne Hathaway and Usher, according to Us Magazine.

However, Lohan may not be smiling for long. She has a hearing Wednesday with a Los Angeles judge who could sentence her to a year and a half in jail for violating the terms of her probation.
