I've just talked to one of the best dentists in my area, he's in this field since 1977. He looked at the x-ray and told me that the root canal
looks absolutely perfect and refused to pull it out no matter what. When I told him that I'm pretty sure that the root canal
is causing me skin problems, like aggravating Acne
and possibly even causing new moles, he said that it's just a coincidence, there's no way that it could affect it.
Then I asked him, perhaps an implant would be better choice for me (since he's also an implant surgeon). He said that I don't need implants yet, the root canal
can be fixed. Well he wasn't thinking only about earning money at least.
Then we started talking about the tooth with the screw. He recommended me another root canal. He obviously thinks that root canals
are absolutely safe.
I'm still not sure who to believe. I'll need to do more research.
