Dr. Arthur Glosman, who does not treat Lohan, examined those recent pics up close and told E! News there's a definite problem going on in her mouth, or what he calls "the door to your body."

"While Lindsay Lohan is not a patient of mine and I have not examined her teeth, in the photographs it appears she has some serious dental problems that need immediate professional dental attention," says Gosman.

"Ms. Lohan is a beautiful young lady but her smile indicates some health problems. It looks as though she has yellow stained teeth, that are chipped at the edges, and possible tooth decay, which could be caused by lack of oral good hygiene, drinking too much coffee, tea, soda and smoking. A visit to her dentist for a thorough exam and treatment protocol should be done immediately."
