Dear Larry,
No, the root canal teeth should not be left if you have any health issues and/ or you do not have regular ozone treatments available to you. There are Holistic Root canals for folks who do no want their teeth out when the nerve dies. These use ozonated water (3000 X better disinfectant than bleach) and a filling material called Biocalex instead of gutta percha.
Yes, the removal of teeth should include the curettage of the socket ("removal of the ligament") including any granulation tissue, periapical pathosis, and a margin of 1mm bone particularly at the root apex and any site of periodontal pathology. I also use platelet rich fibrin created from the patient's own blood to fill the void left as the tooth is extracted. This prevents the need for any foreign / synthetic substances like dead cow or people bone being placed in the body!
The best replacement option in my opinion is the Clear- Met partial. I have posted a picture of just one example of what has proven to be the most well liked, most dependable, most comfortable prosthetic made available in the my 35 year career. It is non- toxic of course!
Other option is an implant. There are now zirconium implants that are not metal, and do not seem to rust like the titanium ones have proven to do. The energetic patterns of the body do not seem to be disrupted by their placement since they are not metal. With the porcelain /zirconium implants, you would need to be sure to have a non- metal crown and connector on the implant.
I do not think that a bridge is a good option because you would have to cut down other teeth- remove all the enamel to make a bridge. Metal partials are not a good option due to galvanic reactions. And, yes, I do think you should replace missing teeth due to the proprioceptive function of the teeth and mouth.
Kind regards,
Dr. Lorie
