When cavities are not detected on time, bacteria can cause inflamation of the tooth nerve or bone tissue around the root. Tooth in this fase usually has pronounced symptoms like spontanious pain without any previous irritation, gum swelling and fistulas above the top of the root. Rarely, it can be asimptomatic, so the dentist can only see the problem on an x-ray image.
A tooth with a cavity requires cleaning and desinfection of the root canal, or so called endodontic treatment. Root canal cleaning can be done by using a special type of a machine or by hand using very thin needles, depending on the assesment of our dentist. After the thorough cleaning and rinsing the root canal, special pastes and Gutta-percha fillings are used to fill in the tooth so it stays hermetically sealed. This way reenfection and bacteria reaching the root canal is avoided.
