plaque
The hard surface of the tooth is made of enamel which is the hardest tissue in the human body. Tooth enamel has no living cells so unlike a broken or fractured bone the body has no way to repair chipped/cracked enamel.
the answer is plaque
Dental plaque is a film-like substance that forms from the acid produced by the combination of food sugars and bacteria on the tooth's surface. It can lead to tooth decay and gum disease if not removed through regular brushing and dental cleanings.
A substrate is a surface or substance in which an organism can attach itself to support its growth. A synonym for substrate is substratum.

The main substance of a tooth is dentin, which is a hard tissue that makes up the majority of the tooth structure. It is covered by enamel on the outer layer and connected to the pulp at the center of the tooth.
A pig tooth consists of a crown, roots, dentin, enamel, pulp cavity, and cementum. The crown is the visible part of the tooth, while the roots anchor the tooth in the jaw. Dentin is the hard tissue under the enamel, and the pulp cavity contains nerves and blood vessels. Cementum covers the roots and helps attach the tooth to the jawbone.
