For a tooth abscess, you want to use food grade calcium bentonite clay, and hydrate clay to make a kind of thick poltice you can pack around the tooth. You want to pack clay on every part of the infected tooth and also the gum around it. For an added benifit you can also make a clay poltice for the outside of your mouth where the infected tooth is. Keep clay on at least 1 hour or more, CB Clay has amazing drawing properties and will draw the infection out. You might feel a pulsating feeling in your mouth as the clay draws out the infection.
I use Food grade bentonite clay mixed with organic olive oil inside my mouth for tooth infections. I became a believer of bentonite when my son had a terrible rash that kept growing and no medicine would get rid of it. I used my homemade bentonite paste on it for about a week and a half and the whole thing went away. I had to keep applying it or the rash would start to grow back. So now I use it for everything!
Toothache: Twice I have had a terrible toothache which I have successfully treated with calcium bentonite clay. I mixed the clay powder with water to make a thick mixture and put a big chunk of it between my cheek and the infected tooth/gums. I changed the clay occasionally, but left it on 24 hours a day, and figured that any I swallowed would be beneficial. It was very effective for my toothache. I think that it works by drawing out the infection and thereby reducing painful inflammation, and that the clay also nourishes. I followed up with eating clay on a daily basis and improving my diet. I had these toothaches about 4 years ago and haven't had problems since.
My favorite way to consume calcium bentonite clay is by making a thick mixture, like pottery clay, which I keep in a lidded jar, and scooping up a little with my finger, and swallowing it with a lot of water. I imagine that this is equally effective as drinking clay water, but it is much more palatable for me.
Montmorillite form of Bentonite clay. I had an absessed tooth that broke off. The absess was not really painful but my dentist advised a root canal because the tooth was dead. How I wish I would have tried the clay first and just had a temp crown put on. I continued to have a soreness at the root. The pocket of infection had been there for years. I didn't want to do the antibiotic thing or have more work done, so I tried the clay. I simply tucked a pea sized bit of clay with a bit of cotton up at the root where the pain was. The next morning it was somewhat better. I continued for months until every bit of the soreness was gone. It took time but I just know I probably could have healed it without the root canal. I still do it once in awhile because I know dead teeth in your mouth infect the body eventually, per Dr. Weston Price. The one advantage?...It takes almost no effort to do.
