Dental question?

When I was a kid, my family never had extra money for anything, and we didn't have insurance, so I never saw a dentist until I was in my mid 20's. I'm 36 now and have several missing teeth, just molars, on the top and bottom on both sides. They've rotted out years ago and eventually broke apart and fell out. But the roots are still in my gums...just the crowns of the teeth are gone. My question is, is there a type of dental bridge that a dentist could fit my mouth with to fill in the spaces where the missing teeth are, even though the roots are still deep in my gums? Or would they have to somehow pull out the roots? It really hurts to eat anything crunchy like tacos, or chips because I end up biting them with my gums, where the tooth should be and that hurts.

No, the roots have to be removed. You wouldn't want trouble brewing under the bridge. Most of the time extracting roots like yours is relatively easy.
