Tooth enamel is one of the hardest substances in our body .How does it gets damaged due to eating chocolates and sweets ? What should we do to prevent it ?

Explanation

Tooth enemel is made up of calcium phosphate , `Ca_(3)(PO_(4))_(2)` , which gets corroded when the pH in the mouth becomes lower than 5.5 .When we eat chocolates and sweets , some particles remain in the mouth .The bacteria present in the mouth produce acids by degradation of sugar and food particles remaining in the mouth after eating .this lowers the pH in the mouth and results in tooth decay .
This can be prevented by cleaning the mouth after eating sugary foods .We can also use toothpastes which are alkaline and neutralise the excess acid and hence prevent tooth decay .
