Decay reaches the nerve in a baby tooth faster; the enamel is thinner.
Infection affects the adult tooth
The developing tooth sits directly beneath.
Spacing
A baby tooth lost early can allow crowding as neighbours drift.
Eating and sleep
Toothache affects appetite, sleep, and school.
Habit-forming
Early positive experiences make later care easier.
What treatment usually involves
Small cavities may be restored simply. Larger ones may need more coverage, and a tooth with nerve involvement may need treatment or removal — sometimes with a space maintainer afterwards to hold the gap.
Prevention is genuinely more effective here than anywhere else in dentistry: sugar frequency, brushing at the gum line, and sealants where indicated.

If you can see a mark or your child mentions discomfort, have it looked at rather than watched.
