Can you tell me docs, is bone loss even real after an extracted tooth?

I would say yes: As an orthopedic surgeon, non weight bearing causes bone loss, i would think the same is true 4 the jaw. With no compressive force from the tooth, i would assume there would b bone loss.

Absolutely: The loss of a tooth removes the internal stimulus that keeps the bone dense and usually results in the bone resorbing. Just ask someone wearing a denture for many years... No ridge left to support the denture, making it uncomfortable. Astronaut's bones become weak, over time, without gravitational forces.. Same principle.

Absolutely: Bone is a living tissue. It completely remodels every 7-8 years in adults in relation to the stress placed on it. If no tooth to support, bone dissolves away. See your dentist to discuss tooth replacement treatment.
