Minerals can return
Early tooth decay can sometimes be stopped or reversed while the enamel surface remains intact. Remineralization restores lost minerals, but it does not simply regrow tooth structure after a cavity forms.
300
Babies have more separate skeletal pieces than adults, often described as about 300 bones compared with the usual adult count of 206. The newborn number is approximate because developing bone and cartilage are not always counted the same way.
1 cm
People are usually slightly taller after a night lying down because spinal discs regain fluid when unloaded. Around a centimeter is a useful rough illustration, not a fixed daily change for everyone.
