I am suggesting, about pulling them out or keeping them, to try full body cleansing first. If you really want to extract those teeth though, do it. I understand the stress and ill health it must have caused you could exhaust your pateince by now. I find that cleansing the bowel, by Dr. Bernard Jensen 's strict standards clears up these teeth infections really well. It is not up to me though, it is up to you.
Wow, swelling in your feet went down after the dental clean up, good! That says to me that your lymphatic system is a bit clogged and overworked from these teeth infections. Exercise is good for the lymph, skin brushing,but maybe you might try those Takara patches too. Its for detoxification, it increases circulation. There is a whole forum devoted to it here on thecurezone website. I am going to try this for myself too.
Whether you choose to pull them out or not, keep your oral health good. I find Miracle2 Neutralizer alkalizes the mouth and body and gets rid of bad bacteria. You can use their gel as tooth paste, although I use their soap. i had a lot of pain in an old root canal before I did this.
