Treatment of Dental Cavities

Baby teeth (also called “primary teeth”) are important for eating, speaking, appearance, and holding space for the developing adult teeth. They are crucial to your child’s overall growth, development, and well-being. If left untreated, cavities can result cause pain, infections, swelling, and damage to the adult teeth.

A cavity is a hole that forms on the tooth. We all have millions of bacteria living in our mouth. When these bacteria eat sugars and other foods in our mouth, they produce acid. The acid causes holes in the teeth to form. It is much easier and less expensive to treat cavities that are small. It is also easier on your child. At Vaughan Children’s Dentistry, our goal is to keep your child’s smile healthy, and this means preventing cavities from developing and treating them early when they do develop.


Common Pediatric Dentsitry Procedures


Protective coating applied to prevent cavities on back adult molars. This is straight-forward, safe, and non-invasive procedure that is well tolerated by children


A filling is a material used to fill a cavity after all of the tooth decay has been removed. At Vaughan Children’s Dentistry we use only tooth coloured filling materials: composite resins and glass ionomers. Some smaller cavities can be filled without local anesthestic (freezing).

Nerve Treatments

A cavity that is deep may involve the nerve. This means that in order to treat the source of the problem, your child may require a form of nerve treatment. This is very common in children’s dentistry and is a painless, straight-forward procedure. This type of treatment may involve:

  • Pulpotomy – partial nerve treatment to preserve the tooth and keep the nerve alive
  • Root Canal Treatment – removal of the nerve of the tooth, disinfection, and filling of the root


A cavity that is large, deep, or that affects multiple surfaces of the tooth may require a crown to go around the tooth. This is very different from a crown that would be placed on a permanent tooth.

These crowns are quick to place and done in a single visit. Depending on the location of the tooth, there are different types of crowns that we use.  In the majority of cases, especially involving back teeth, stainless steel crowns (metal) are used. Our practice is proud to offer a non-metal alternative. Click here for more information on non-metal, white crowns.


For a tooth that is not-fixable or infected, we may recommend removing the tooth limit any damage.

Space Maintainers

When a baby molar (back tooth) is lost early from a cavity, infection, or accident, a space maintainer can be used to prevent the remaining teeth from shifting. This helps to hold space until the adult teeth are ready to erupt. Common space maintainers include band-and-loop, transpalatal arch, nance, and lingual arch.
