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. Despite your best efforts to ensure good dental hygiene, sometimes kids end up with cavities. Cavity care for children is very similar to cavity care for adults because preserving tooth health is the most important aspect. 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.
