Charlie Sheen Toothless

Charlie Sheen Toothless, Porn Star Kacey Jordan Says: What Happened?

(CBS) Has Charlie Sheen lost his choppers?

A porn star who says she partied with the bad-boy actor - now reportedly in rehab - says his teeth are mostly gold and that he wears a white dental apparatus to look presentable in public, a popular gossip site reported.

Kacey Jordan made the claim during a recent interview with gonzo radio host Howard Stern, according to radaronline.

"All his teeth have fallen out from partying," Jordan said, according to the Daily Mail. "He kept saying f****** porcelain teeth... they crap. Said he had to get gold teeth. Most of his teeth fallen out, he wouldn't say why but we all know it's because of the drug use."

While we don't really know the condition of Sheen's pearly whites, dentists say there's no doubt that certain drugs can cause tooth loss, some legitimate drugs, but illicit ones too. Methamphetamine (crystal meth), for instance, is such a notorious cause of tooth loss that doctors call the condition "meth mouth."

But drug abuse is far from the only cause of tooth loss.

"It's very hard to speculate," says Dr. Edward M. Feinberg, a dentist in private practice in Scarsdale, N.Y. "There are a lot of things that can contribute to tooth loss."

According to WebMD, certain chronic medical conditions can cause tooth loss, including chronic conditions like high blood pressure, diabetes, and rheumatoid arthritis. And tooth loss is more common in men over the age of 35 as well as in smokers and in those who fail to see a dentist.

And then, WebMD says, there's another risk factor for tooth loss: Not using a toothbrush.
