Even for baby teeth, it is important to treat tooth decay with fillings. Advanced tooth decay, whether in primary or adult teeth, can cause pain and in some cases can even lead to an infection when left untreated. Baby teeth preserve the space needed for the proper eruption of the adult teeth that will replace them. Therefore it’s important to avoid losing them prematurely in order to optimize the alignment of the adult dentition.

Once decay on a baby tooth reaches the pulp (bundle of blood vessels and nerves at the center), a pulpotomy is often necessary. During a pulpotomy, the dentist will remove the decay as well as the affected pulp and then place a restoration.
