The term “soft teeth” is simply a way of describing teeth susceptible to cavities. Teeth prone to cavities can result from a variety of factors such as hygiene and diet; however the term “soft teeth” is not a medical one.
Many claims of soft teeth can be explained by an inconsistent hygienic 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. The mineral fluoride helps prevent cavities by remineralizing and strengthening the enamel. When fluoride and other minerals are absent, teeth are increasingly susceptible to decay.
