What Ph Does Enamel Demineralize?

Your enamel starts to demineralize when exposed to a pH level of about 5.5. And that can cause many oral issues, including tooth sensitivity and decay.

At which pH level does enamel demineralisation occur?

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.

What pH causes demineralization of teeth?

Acidic environment– Decay formation is the result of demineralization (the loss of mineral content) from teeth. This is a process that occurs when a tooth is exposed to an acidic environment of pH 5.5 (referred to as the Critical pH) or below.
