Many claims of soft teeth can be explained by an inconsistent hygiene routine, regular intake of junk food, candy, and soda, or a lack of fluoridated water.
When the teeth are not properly cleaned, particularly after eating, bacteria can break down enamel and cause cavities. Regular exposure to sugars increases the rate of enamel breakdown by feeding harmful bacteria.
Fluoride helps prevent cavities by remineralizing and strengthening the enamel. When fluoride and other minerals are absent, teeth are increasingly susceptible to decay.
