Root canal treatment is a system to expel sick mash from a root channel in your tooth. Every tooth has a crown, dentin, mash, and at least one roots. The crown is the piece of your tooth that you can see. Dentin is hard tissue under the crown that encompasses the mash. The mash is tissue that contains nerves and veins that fill your tooth roots. Each root anchors your tooth to your gum and jawbone. A root channel can treat tainted mash or a boil (discharge take) around your tooth root. You may require root waterway treatment on the off chance that you have an opening in your tooth from a hole (rot).
