My daughter has had every baby tooth pulled because the adult tooth was unable to push it out. Now, due to impacted teeth, we have the option of keeping in her baby canine teeth or going through 2 years of painful orthodonture. We’re leaning towards keeping in her baby teeth and removing the impacted ones. She has small adult teeth so the baby canines fit right in. My question is how long can these baby teeth stay in? Do the roots of baby teeth have a life span or will they last "forever" if no adult tooth is pushing it’s way in?

I’m in my 30s and had to have two baby teeth removed. The roots were closer to the surface than adult teeth are and hot foods (especially coffee) really hurt.
I now have to get two implants (cost, about $4500 and no insurance company covers implants).
Go for the orthodontic now or she will have to have it later and it will be more expensive and not covered by her insurance.
