Tips

usage
Almost always in the medical term 龋齿 (dental caries / a decayed tooth). In everyday speech people more often say 蛀牙 ('cavity / worm-tooth') for the same thing.

Components

radical
齿 chǐ
tooth
Left side 齿 is the tooth radical, fixing the meaning squarely on teeth. Same family as 龄 age (counted by teeth) and 龈 gums.
phonetic
禹 yǔ
Yu (legendary flood-taming emperor)
Right side 禹 serves only as a sound element (yǔ → qǔ); it carries none of emperor Yu's meaning into this dental-decay word.
