This is general information for parents, not a diagnosis. How a particular tooth should be treated is decided after the child has been examined.
Quick Answer
Yes, decay in baby teeth usually needs attention. Baby teeth help children chew, speak and smile, and they hold space for the adult teeth underneath. The back baby molars often stay until around 10 to 12 years of age. Decay can progress faster in baby teeth because their enamel is thinner, and untreated decay can cause pain, infection, and a swollen face, and can lead to early loss of the tooth, which can affect where adult teeth come in. Treatment depends on how deep the decay is and how long the tooth has left: early decay may be stopped with fluoride and better habits; cavities may need a filling; deeper decay may need nerve treatment and a crown; and a badly broken-down tooth may be removed, sometimes with a space maintainer. A tooth that is about to fall out naturally may simply be monitored.
Key Takeaways
- Baby teeth matter for eating, speech, confidence and guiding adult teeth.
- Some baby teeth remain until around 12, so decay may need treating even years before they fall out.
- Decay can spread faster in baby teeth.
- Options range from fluoride and monitoring to fillings, crowns and extraction.
- Prevention at home is the most effective treatment.
Why Baby Teeth Matter
- Space keeping. Each baby tooth holds space for the adult tooth below it. Losing one early can let neighbours drift and leave too little room. See when should a child see an orthodontist.
- Eating and growth. Painful teeth make children avoid foods.
- Speech. Front teeth help form some sounds.
- Infection. An abscess on a baby tooth is painful and can, rarely, affect the developing adult tooth.
How Long Baby Teeth Stay
Front baby teeth are usually lost between about 6 and 8 years of age. The back baby molars are usually lost between about 10 and 12. A cavity in a baby molar at age 5 may have to last six or seven more years, which is why "it will fall out soon" is not always true.
Treatment Options
| Situation | Typical approach |
|---|---|
| Early decay, no cavity | Fluoride varnish, better brushing and diet, monitoring |
| Small cavity | Filling, often tooth-coloured |
| Larger cavity | Larger filling, or a preformed crown on a back tooth |
| Decay reaching the nerve | Nerve treatment of the baby tooth (pulpotomy) and a crown, or extraction |
| Abscess or tooth beyond repair | Extraction; a space maintainer may be considered |
| Tooth close to falling out naturally | Monitoring, if it is not causing pain or infection |
Some dentists also use treatments that arrest decay without drilling in suitable cases. Ask what options apply to your child's tooth.
Making Treatment Easier for Your Child
- Start dental visits early, so the first visit is not for a problem. See your child's first dental visit.
- Talk about the visit calmly and avoid words like "hurt" or "needle".
- Stay with your child; at Adil Dent Clinics, parents stay with the child and are involved in every decision.
- X-rays for children are taken only when clinically needed.
Preventing Decay at Home
- Brush twice a day with fluoride toothpaste in an amount suitable for your child's age, and supervise brushing until about age 7 or later.
- Spit, do not rinse, after brushing.
- Keep sugary food and drinks to mealtimes; avoid sugary drinks in bottles and at bedtime.
- Ask about fluoride varnish and fissure sealants. See fissure sealants and fluoride varnish.
- Keep regular check-ups. See can a cavity heal.
When to Seek Prompt Care
- Facial swelling, or a swelling on the gum near a tooth
- Toothache that keeps your child awake
- Fever with dental pain
Facial swelling with fever, or difficulty swallowing or breathing, needs urgent medical care immediately. See dental emergencies.
Conclusion
Baby teeth are temporary, but some are temporary for a long time. Treating decay early keeps children comfortable and protects the space for their adult teeth, and prevention at home does more than any filling.
