Paging Monica Lewinsky! She may have gone to the dentist for a teeth cleaning -- but what Brit really needed was to clean her dress!

Spears and her reblondered, semi-hellacious weave went in and out of two different dental offices yesterday, wearing a noticeably grease-smeared frock. A tub of OxiClean only costs $7.99.
