Had to post this.
above is a really impressive video on root canals!
Seems the residue left under the tooth post root canal is super connected to the health of the rest of the body. Especially, in heart disease and cancer of almost anything.
It's truly amazing the connects of root canals that are almost impossible to clean out everything.
Bottom line you can't even tell from most dental x-rays since they are two dimensional instead of three dimensional. Unless your dentist is holistic and has a 3D cone X Ray for teeth your x ray is not showing any damage from previous root canals.
It's not 100% of previous root canals that may look perfect on the surface but over 90% of them that have problems under the surface of left over bacteria that continues to grow and is fed into the body creating all kinds of medical problems.
This video will change what you thought you knew about your teeth,it changed it for me.
Also, the video suggests to have only zirconia replacements of any teeth that are pulled,even titanium which last forever are not foolproof by any means since they are metal.
99% of root canals are not cleaned out properly no matter how good they look on a two dimensional tooth X Ray machine.
Also, some people do not exhibit problems after a root canal due to their superior immune system,everyone is different.
Needless to say the average dentist does not have a clue about any of this and will fight you “tooth” and nail.
So watch the video.
