Hi Teri, make sure you request a local anaesthetic without a vaso constrictor (they restrict blood flow and can increase the chances of a cavitation becaue of that).

And ask that the periodontal ligament be removed as well as the tooth. Anything to cut down the risks of a cavitation forming is helpful.

Plus, diet is very important for healing, proteins (eggs, meats), fats (butter), vegetables, nuts/seeds, all these things will help bone healing. To help aid your body against infection and if you can handle it, garlic may also help (natural antibiotic) and vitamin C (but do NOT take vitamin C 24 - 48 hours before an anaesthetic, or it will erase the effects and you will feel pain). Other than that, take the vitamin C.

cod liver oil is also wonderful, but get a brand that is free of mercury (blue ice for example).

Don't need to go overboard, but some simple things like this can all help. And I would also do what sosick suggests and use the hydrogen peroxide too and do the salt water rinses for the mouth. If they insist you be on antibiotics, well that's up to you, but if so, I would take probiotics to replace the good bacteria! 2 hours before or after antibiotics. Take a lot of it too during the process and possibly for a few weeks following to make sure you replace any bacteria that was wiped out.

Just some tips, I wish there were ideal answers.
