Dentist wants root canal done. How to avoid this?

Hello! My grandmother's dentist told her that she needs to have a root canal on 3 teeth. I've read so many bad things about root canals and it leading to more problems, what can she do to avoid this?

Since she was experiencing lots of pain from the infected teeth, they had put her on Antibiotics . The Antibiotics made her very weak and ill. She has finished them and is now feeling better since off of them. The dentist still wants to go ahead with the root canal. Her teeth are still infected and swollen.

I read that oregano oil dabbed onto the infected teeth could help. Also, swishing with himalayan salt, Colloidal Silver , and unrefined coconut oil could be of help too, what do you think?

Please, any advice would be helpful Tweet
