Dental caries (commonly referred to as a “cavity” or “tooth decay”) is a process by which oral bacteria digest sugar residues, producing byproduct acids that soften your enamel and dentin. In some cases, tooth decay causes pain and sensitivity while, in other cases, there are no symptoms whatsoever. If left untreated, dental caries progress toward the center of your tooth where your nerve resides and this can result in the need for root canal treatment.

When treating dental caries, Dr. Hornby provides local anesthesia to numb the affected tooth. This is followed by removal of soft decayed enamel and dentin. In the final step, a tooth-coloured filling is bonded to the tooth to fill the void created by decay removal.

Tooth-coloured fillings are also placed as a means of restoring fractured or broken teeth.
