At what pH does enamel Demineralize?
Herein, at what pH does dentin Demineralize?
At a pH of 5.5 the teeth begin to demineralize, putting them at risk for cavities. A healthy mouth is in a neutral pH range. To keep your teeth healthy, you must keep oral acidity to a minimum. Teeth can actually become stronger and remineralize when the mouth has a pH of 7.5 or above.
Similarly, you may ask, what is the critical pH of enamel?
The critical pH is the pH at which saliva and plaque fluid cease to be saturated with calcium and phosphate, thereby permitting the hydroxyapatite in dental enamel to dissolve. It is the highest pH at which there is a net loss of enamel from the teeth, which is generally accepted to be about 5.5 for enamel.
Calcium phosphate is present in tooth enamel and it is known as hydroxyapetite which is basic in nature.
