Explanation:
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.
