As the acidity in the mouth increases tooth decay happens as the calcium in the teeth gets corroded. Any base such as toothpaste prevents this from happening. Our saliva in our mouth also helps to decrease the PH in the mouth.

pH Change Leads to Tooth Decay
Tooth enamel is made up of calcium phosphate and
is the hardest substance in the body. If the pH inside
the mouth decreases below 5.5 (acidic), the decay of
tooth enamel begins.
The bacteria present in the mouth degrades the
sugar and left over food particles and produce acids
that remains in the mouth after eatihg.
The best way to prevent this is to clean the mouth
after eating food. To prevent tooth decay,
toothpastes (basic) are used which neutralise the
excess acid.
