Why do children's teeth decay so quickly?
Baby-tooth enamel is thinner than adult enamel, so decay spreads faster. Tooth decay is one of the most common health problems in children โ even though it's largely preventable. This guide explains causes and signs, when decay must be treated, and how to protect your child's teeth.
Causes of tooth decay in children
- Falling asleep with a bottle of milk or juice ("bottle caries").
- Frequent sugary snacks and juice between meals.
- Not enough cleaning โ children can't brush well alone before age 7โ8.
- Too little fluoride.
- Bacteria passed from adults, such as sharing spoons.
Signs of decay in children
- Chalky white spots near the gumline โ the first stage, which can be stopped.
- Brown or black spots, or holes.
- Sensitivity or pain when eating or drinking.
- Refusing food, or chewing on one side.
- Swollen gum or a "pimple" near a tooth โ an abscess that needs prompt treatment.
Should decay in baby teeth be treated?
Yes. Baby teeth matter for chewing, speech and holding space for adult teeth. Untreated decay can cause:
- Pain and infection affecting sleep, eating and concentration.
- An abscess that may affect the developing adult tooth underneath.
- Early tooth loss, which can lead to crowding of adult teeth later.
How is decay treated in children?
| Stage | Treatment |
|---|---|
| Early white spots | Fluoride varnish plus better cleaning and diet |
| Small or medium cavity | A child-friendly filling |
| Decay reaching the nerve | Baby-tooth nerve treatment, often followed by a crown on molars |
| Badly damaged tooth | Extraction, with a space maintainer if needed |

Frequently asked questions
