The epithet "meth mouth" is the result of these superficial presentations of advanced tooth decay and gum infection. Caries often occur in the cervical regions of teeth , where the tooth surface narrows at the junction of the crown and the root; decay is primarily centered on the buccal ( cheek ) side of the teeth, and on tooth surfaces that ...
Tooth decay is caused by biofilm (dental plaque) lying on the teeth and maturing to become cariogenic (causing decay). Certain bacteria in the biofilm produce acids, primarily lactic acid , in the presence of fermentable carbohydrates such as sucrose , fructose , and glucose .
Along with S. sobrinus, S. mutans plays a major role in tooth decay, metabolizing sucrose to lactic acid. [2] [11] The acidic environment created in the mouth by this process is what causes the highly mineralized tooth enamel to be vulnerable to decay.
Green arrows indicate tooth decay. Blue arrows indicate abscess at root of tooth. The infection at the root of the tooth can travel through bone and infect surrounding soft tissue. Mouth infections are usually diagnosed on history and physical exam in the dental office or at a clinic visit with an otolaryngologist. [1]
It is a likely outcome of untreated dental caries (tooth decay), and in such cases it can be considered a sequela in the natural history of tooth decay, irreversible pulpitis and pulpal necrosis. Other causes can include occlusal trauma due to 'high spots' after restoration work, extrusion from the tooth of root filling material, or bacterial ...
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 ...

The belief that tooth decay and dental pain is caused by tooth worms is found in ancient India, Egypt, Japan, and China, [9] and persists until the Age of Enlightenment. Although toothache is an ancient problem, [55]: 48–52 it is thought that ancient people suffered less dental decay due to a lack of refined sugars in their diet.
