Thanks harlygirl for your informative response! The big issue that needs clearing up, is what all that red, grade 4 lesions, on the cavitat scan mean.Areas where I have had the most dental work, the 4 corners have a lot of red. Even though I have 31 functioning teeth. According to the cavitat its all necrotic bone, and orange is also bad.The pano x ray shows "normal". Now whats needed via Boyd Haley in Kentucky, Bob Jones in Colorado, and others is a series of tests to determine if that is really the case. Now less dense bone, is that all it is? The wisdom tooth area gets little chewing pressure. That could be one of the problems, but it looks suspicious to me that those areas are where Amalgam fillings were removed, and had crowns replaced etc.High speed drilling and vasoconstricting anesthetics, are they damaging the tooth and jawbone? That is the big question? THE WATERLASE, see website is one answer(less/no anesthetic/no heat). Also see http://www.garynull.com Web site, search under dental, dental anesthetics, and read the Dr Alfred Nickel article about lidocaine based anesthetics being a potent carcinogen. So that's still what people are being shot up with. SEPTOCAINE is analine free. BUT its only available WITH vasoconstrictor in USA.(I am aging some, 2yrs to dissapate the vaso) In France PLAIN is available. But some people don't have the enzyme to break it down. Do search on WEB of German article on that subject. The other choices are Marcaine, for MEDICAL use,which is low analine.Sedation dentistry, twighlight sleep.This crap all begins with stupid cultural idiocy called "Haloween Candy" etc! Ban all candy! Send candy and soda makers to Guantanamo!(and kind, dumb grandparents with them!)Regarding bone fillers. Some dentists do, others don't. My one cavitational surgery(badly needed from infected tooth) healed just fine. Dr. Keramati,(Hussar's Dentist)in Encino,CA, did a super professional job, on that. Elliot K
