dental implants need a lot of continuous hygiene.
if one is too lazy for that, like me, it is a waste of money.
there should be healthy bone to begin with.
zirconia is a problem emf-wise.
dentists are robbers by profession, it is hard to find an honest and sane one.
quite a few holistic / biologic dentists follow the scientology-church and pay large sums to have evil spirits removed.
the richer a follower, the more evil spirits of course, i heard about a dentist who paid a million usd ( and yes, he had to charge his customers first ).
anyway, get informed before doing anything to your teeth.
lack of ( absorbed ) vitamines and minerals cause a lot of dental problems.
calcium is important, raw milk-products are a great source, but pasteurized means dead enzymes and mal-absorption.
vitamin d seems also crucial, preferable no synthetic version of it.
especially vegans need to pay attention here, and eat large quantities of vegetables.
very recommendable in case you have a dead tooth in your mouth :
" the toxic tooth : how a root canal could be making you sick " by Kulacz and Levy.
this is serious stuff.
