How and Why Do Dentists Fix Cavities for Children?
Though children are using a set of teeth they will eventually lose, that set of teeth needs to survive until the adult teeth guide them out of the gums, which helps ensure the adult teeth grow incorrectly and with enough room. That’s why oral hygiene is important as soon as a baby’s teeth begin to come in, and teaching oral hygiene should begin at a young age.
Baby Teeth Get Fillings Though baby teeth aren’t permanent, they are the only teeth your child will have for several years, until the adult teeth come in. To preserve your child’s oral health, your dentist will opt to drill out the cavities in baby teeth and fill or crown them accordingly. The primary teeth help the adult teeth to come in properly, so losing primary teeth before they’re ready to come out isn’t good for your child’s permanent teeth.

Your dentist will drill the tooth decay from your child’s baby teeth as necessary. Depending on how much damage the cavity has caused, the dentist will then fill the tooth or create a crown. Kids should continue using good oral hygiene when caring for fillings or crowns, whether those repairs have been done on baby teeth or on permanent teeth.
