I got root canals at the age of 11 I am now 21. I once had to get them replaced because of an infection when I was roughly 16-17 years of age. I haven't had a regular check up in about 2 years. I am just concerned and anxious because I know it's a real thing that people die from root canal infections. But I am working on getting health insurance so I can go get them checked. Do they look bad?
