Why does tooth decay start when the pH of mouth is lower then 5.5
Answers
Answer:
Explanation:
Because ph 7 is considered to be neutral and if the ph is above 7 then it is considered to be basic in nature. On the contrary if ph is below it is considered to be acidic in nature.
The tooth at 5.5 becomes acidic so it causes tooth decay.

Answer:
⇒ Bacteria present in mouth produces acids by decaying the food particles present in our mouth which is left in mouth after eating.
⇒ The acid is so strong that it attacks the enamel (strongest and toughest tissue in human body) can starts to decay under its action.
⇒ Tooth enamel, made up of calcium phosphate. It is not soluble in water.
⇒ The enamel gets corroded in pH less than 5.5 and tooth begins to decay.
⇒ To prevent this we should brush our teeth wit toothpaste because it contain base.
