Acidity is measured using the PH scale. This rates acidity on a scale from pH1, which is extremely acid, to pH14, which is extremely alkali and Neutral is rated as pH7.
Tooth enamel dissolves at an acidity below pH5.5. Dentine, which makes up the inside of the crown plus the root dissolves at pH6. So, if we start with the mouth being neutral and then change it to a pH of 3.5 by drinking an acid drink, the tooth surface can be dissolved because the tooth is bathed in something that’s a hundred times more acidic than needed to dissolve it!
An acidic diet, combined with abrasive whitening toothpaste will strip the enamel leading to a rough hollow in the tooth that will collect stains. The only sensible solution here is to clean away the stain and then fill the area in with white filling material. But the white filling material will eventually pick up stain itself.
Remember the cut off for safety is at 5.5 for enamel and 6 for dentine. And what happens if the tooth surface is eaten away is the teeth become very senstitive!
