Why clean your tongue?

Many patients give little thought to tongue care when dental hygiene is concerned. If you are one of them, read on. The top rear part of most tongues has a coating of millions of organisms. During the spoiling of debris on the tongue, hydrogen sulfide and methylmercaptan are produced, both of which have been related directly to oral malodor. It has been estimated that the debris in the mouth may be responsible for up to 90 percent of oral malodor. The evidence is clear that organisms are present on the tongue in enormous quantities, that these organisms contribute to halitosis and that tongue scraping or brushing reduces plaque scores in the mouth.
