In general, you should have this done as soon as possible, especially if it's a posterior (back) tooth like a molar or premolar. A tooth that has had root canal treatment becomes more subject to fracturing.
D3330 is a molar root canal
6 year olds get their first adult molar at the back of the mouth , and if a cavity gets too deep quickly, the nerve will die, and the tooth will need root canal treatment.
If you have a root canal done, most likely you'll need a crown. But if it was done through a bridge, there is already a crown on that tooth. A bride is just three or more crowns fused into one piece to replace a missing tooth. It is possible that doing a root canal through the brige will damage the bridge and the whole until may need to be replaced if that happens. But that's not common.
A cracked molar may require a root canal if the fracture extends into the pulp, where the nerves and blood vessels are located. This can lead to infection, pain, and further damage if not treated. A root canal removes the infected tissue, alleviates pain, and preserves the tooth, allowing it to function normally. If the crack is superficial and doesn’t affect the pulp, other treatments might be sufficient.
Root canal surgery is done by an endodontist.
