Question

Muh ka ph 5.5 Se Kam hone par dant kharab hona kyun shuru ho jate hai​

Answer 1

Answer

when we eat sugary substance like (sugar,juice, chocolates) they settled into our teeth..If we don't clean our teeth properly the bacteria in our teeth act on the sugary substance and make a hole in teeth..

This is the reason for decreasing ph of our mouth..

When the pH of our mouth decreases and become less than 5.5 it means our teeth become more acidic... Presence of excessive acids in our mouth provide energy for Bacteria and this bacteria continue to make hole...

firstly the enamel the outer layer of teeth damaged then dentine and if we don't go to doctor the pulp cavity also damaged.. pulp cavity is a layer of soft muscular tissue and when this damaged it cause pain..

Thus due to improper cleaning of our teeth the ph decrease and acid increase... Bacteria make hole and cause cavities..
