what are the factors that cause the damage to teeth mentioned earlier?
The use of tobacco, Reduced salivary flow rate, biofilm
Tooth decay
biofilm
when did they start putting fluoride in water 1945 what was the objective of doing this? Water fluoridation is the controlled adjustment of fluoride to a public water supply to reduce tooth decay. what is this substance mentioned here? It is an inorganic, monatomic anion, whose salts are typically white or colorless. how is it associated with teeth? Fluoridated water operates on tooth surfaces: in the mouth, it creates low levels of fluoride in saliva, which reduces the rate at which tooth enamel demineralizes and increases the rate at which it remineralizes in the early stages of cavities. is it found in any food consumed by humans? Seafood, tea, and gelatin. is this element used in batteries? Yes, Fluoride-ion Battery

Tooth decay [SEP] Cause
Four things are required for caries formation: a tooth surface (enamel or dentin), caries-causing bacteria, fermentable carbohydrates (such as sucrose), and time. This involves adherence of food to the teeth and acid creation by the bacteria that makes up the dental plaque. However, these four criteria are not always enough to cause the disease and a sheltered environment promoting development of a cariogenic biofilm is required. The caries disease process does not have an inevitable outcome, and different individuals will be susceptible to different degrees depending on the shape of their teeth, oral hygiene habits, and the buffering capacity of their saliva.
