answer:First off if I felt my life was on the line I would not be asking for advice here especially in Social. If you want responses as serious as can be afforded here, ask this in General. Perhaps the Mods could help out and move this to General. That said as far as I have read, poor dental hygiene has been connected overall health issues as you have stated. I would not panic but do consult with the Dr./Dentist you are having the tooth extraction with as to where this journey could lead you in the long run. Bad teeth are IMHO reflective of a greater neglect of ones health overall. I doubt this will kill you straight away but maybe just a wakeup call for you.
