State true or false:

Acid affects teeth.

Enamel, dentin, cementum, and pulp are the four distinct tissues that make up a human tooth. Here, only the first sort of tissue—enamel—needs to be taken into account.
The enamel is the teeth's exterior hard covering. It is composed primarily of inorganic substances and powerful minerals, including hydroxyapatite, a mineral form of calcium phosphate, making it the hardest tissue in the human body. Because of how tough enamel is, it can endure severe forces and changes in acid-base balance.

However, the enamel becomes vulnerable to demineralization when the oral pH falls below 5.5 (becomes excessively acidic). Demineralization is the process through which minerals are lost or dissolved under the influence of acid. When there is too much acid in the mouth, hydroxyapatite crystals' phosphate reacts with the acid to create hydrogen phosphate species, which dissolves.

According to the process described below, when the acid level is high, the reaction will move forward and calcium ions will continue to be removed from the mineral. As a result, the tooth enamel becomes more vulnerable to decay, which can lead to the development of cavities, dental sensitivity, tooth discolouration, etc.

${\mathrm{Ca}}_{10}{\left({\mathrm{PO}}_4\right)}_6(\mathrm{OH}{)}_2+14{\mathrm{H}}^{+}\rightleftharpoons 10{\mathrm{Ca}}^{2+}+6{\mathrm{H}}_2{\mathrm{PO}}_4^{-}+2{\mathrm{H}}_2\mathrm{O}$
Hydroxyapatite + Hydrogenn ${}^{+}\rightleftharpoons$ Calcium ${}^{2+}+$ Phosphoric acid + Water

Therefore, the given statement is true.
