It may be prepared via the Schiemann reaction, in which a 4-aminobenzoic acid, protected as the ethyl ester, is diazotised and then fluoride introduced using tetrafluoroborate. Hydrolysis of the ester converts it back to the free acid. [2] 4-Fluorobenzoic acid has been observed to form by the aerobic biotransformation of 4-fluorocinnamic acid. [3]
Since dental floss is able to remove some inter-proximal plaque, frequent regular dental flossing will reduce inter-proximal caries and periodontal disease risks. [ 1 ] [ 3 ] Results of a high level of evidence meta-analysis recently found that floss may not be the most effective method for interdental cleaning, contrary to common belief at the ...

A 1930s poster from the Work Projects Administration promoting oral hygiene. Tooth decay is the most common global disease. [14] Over 80% of cavities occur inside fissures in teeth where brushing cannot reach food left trapped after eating and saliva and fluoride have no access to neutralize acid and remineralize demineralized teeth, unlike easy-to-clean parts of the tooth, where fewer ...
Dental floss (waxed) Levi Spear Parmly (1790-1859), [4] a dentist from New Orleans, is credited with inventing the first form of dental floss. [5] In 1819, he recommended running a waxen silk thread "through the interstices of the teeth, between their necks and the arches of the gum, to dislodge that irritating matter which no brush can remove and which is the real source of disease."
An oral irrigator (also called a dental water jet, water flosser or, by the brand name of the best-known such device, Waterpik) is a home dental care device which uses a stream of high-pressure pulsating water intended to remove dental plaque and food debris between teeth and below the gum line. Regular use of an oral irrigator is believed to ...
