The hard, dense tissue that makes up most of a tooth, located under the outer layer of enamel and surrounding the inner pulp.

Example

The dentist explained that dentin is important for the strength and structure of the tooth.

Conversation

Did you know that dentin is actually the main part of a tooth?

Really? I thought enamel was the most important part.

Enamel is important too, but dentin is what gives the tooth strength.

That makes sense! I guess both layers work together to protect our teeth.

Root Explanation

**Dentin** → It is derived from the Latin word "dens" (meaning tooth) and the suffix "-in" (used to form names of substances). The word "dentin" refers to the hard tissue that makes up the bulk of a tooth beneath the enamel.

Memory Tip
