My mother's job charges anywhere from $400 - $800 per extraction!!!! Depends which tooth, whether it is, if it's impacted, if its simple or not, etc. It's always good to be proactive- brush teeth mornings and nights and in between meals, mouth wash, floss, dental visits every 6 months, low on sweets, wines, sodas, anything acidic than can weaken enamel, etc. But you are talking about losing a tooth in the matter of hours on occasions. So you may be way past preventative care
. But of course you can still do all these things!
I think a consultation is the best route. That way you can get all your ducks lined up and see what needs to be done. You can explain to the doc that you are looking for the most affordable fix at the moment.
