Hello so I'm 16 and I had a root canal done about a year ago the thing is that it was never finished because I think my roots won't mature enough.. welll now it's a hole with bits of tooth in the whole it looks like its rotting and it also taste like that too.Also it is sore sometimes especially when something pushes on a part of surronding gum. My mom doesn't like going to the dentist/docters in less its really needed. Should I be concerned for my tooth and health?

You should be concerned. You are going to end up losing the tooth if you don't get the root canal completed. I've never heard of a tooth being left with a root canal partially completed because of roots not being "mature" enough. I know of many people who have had root canals done before they were 16 and the root canal was completed immediately.

The longer your tooth sits hollowed out, it will crumble and the root will rot which will make it much more difficult when it comes time to remove it.

See your dentist as soon as you can.
