Answers

False: Teeth are the strongest naturally occurring substance on the planet.
Tooth enamel is the strongest substance in the body, but it’s second to diamonds when it comes to all naturally occurring substances on the planet earth.

True: Teeth are 96% minerals.
The other 4% consists of proteins and water.

False: All adults have 4 wisdom teeth.
Some people have 1, 2, or 3 wisdom teeth, while a rare few have 5. Most humans have 4.

False: All babies are born toothless.
Some babies are born with a tooth or two! It’s rare, but it happens.

True: Fluoride (in toothpaste and tap water, for instance) speeds up calcium and phosphate into tooth enamel.
Fluoride is a mineral that has the cool ability to attract other enamel-strengthening minerals.

True: Without teeth roots, jawbone can degenerate.
Teeth roots stimulate jawbone tissue to remain intact. When teeth are lost, the bone will begin to deteriorate if those teeth are not replaced with dental implants.

False: The entire outer layer of a tooth is made of enamel.
A tooth’s root has no enamel. That’s why gum recession causes tooth sensitivity; it exposes unprotected roots.

False: The layer under tooth enamel is called dental pulp.
The outer layer is enamel, then comes dentin, and then dental pulp, within the tooth’s canal.
