MMS can help with bacteria to some extent, though it has limited diffusion and anti-inflammatory properties. That said, you'll want to be careful with acidic compounds as this could easily aggravate the tooth further.

That said, one very good instant pain reliever for toothaches is DMSO, which can be dropped in the infection tooth.

Beyond this if your tooth is compromised to root, then there really isn't much more you can do beyond pulling it. As it will continue to deteriorate until the tooth dies. After which, you will be left with a systemic infection with the potential to compromise the bone, and is far more dangerous than any toothache. - take it from someone who's been there. - it aint worth it!


PS. For diffusion, Colloidal Silver is a far better alternative for toothaches along with coconut oil(pulling). Though the latter requires a measure of time(several days) for a regime to take effect. Whereas the DMSO can provide instant relief until you get there.

Good luck and don't wait too long to take care of that tooth.
