What is the reason of tooth decay. Explain |
|
Answer» When the ph value in our mouth is less than 5.5 then it is acidic in nature and the enamel of our teeth gets corroded hence resulting in tooth decay Certain bacteria in the mouth produces acids while breaking the food particles, reduces the pH level less than 5 in the mouth. Because of this enamel on the tooth gets damaged by the acids. If this continues it leads to tooth decay.Tooth pastes are the basic in nature. Regular usage of tooth paste reduces acid levels present in the mouth, thus decreases tooth decay. Our mouth becomes acidic if pH value is lower than 5.5 Hence tooth decay |
