hey mate!!!! here is your answer
Tooth decay starts when pH of mouth is lower than 5.5
Tooth enamel made up of calcium phosphate ( hardest substance in body) does not desolve in water but corrodes when pH is lower than 5.5 due to acids produced by degradation of food particles by bacteria.

Using toothpaste (base) can be prevented

Tooth enamel is made up of calcium phosphate and is the hardest substance in the boby. 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 eating.

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.
