I have a root canal treatment and crown similar to the original post. I get regular low level pain and throbbing but no other symptoms I would attribute to my tooth so far. I want to treat the tooth properly but I'm not sure how to go about it. Your suggestion sounds good but my tooth is constantly visible as it is one of my front teeth. I've started looking for holistic dentist in London and will now research biodentists too. What would you recommend in my case? And what has your own experience been?
