Thanks, Bryanna,

I did physically see the doctors, some oral surgeons just don't believe cavitation and root canal related statement while others said my front teeth root canal is not that bad to need to be pulled out.

Anyway, I have been pregnant and breastfeeding for all past two years, so couldn't pull out the infection ones.

My question now is based on what I described, do your think other than my remain root canalled teeth, all other that has been extracted in the past are definitely developed into a cavitation and I need to take care of that asap as well? Sorry I keep asking you this because in my city there's really no understanding oral surgeon can help me in this side. Do you know any good dentist in Vancouver? Thanks!
