I have finally made the decision to have two teeth extracted- both are root cabal/ crowns. They are both on the bottom, opposite of each other- Second to the last teeth (sorry- don't know correct term for these teeth). The one on the right side is an old, cracked canal that has been absessing (small) for years- no real pain. I drain it and clean it. The other one is a year old, and I know it's bad- not cracked, but causes more pain then the other.
My questions are regarding bridge/ and or implants. I've heard varied opinions as to why I HAVE to get something or else my teeth will shift dramatically. My issue is cost- I cannot afford either- even through a credit arrangement.
Would love some feedback, please!!!

BTW I take really good care of my teeth- too late in the game, but I keep at it.
