That is exactly how I hit the nightmare of osteoporosis.
I was told to go off of it before extraction/implant, which I did. I was due for my next dose of Prolia about 6 weeks after dental procedure. My doctor said it would be fine.
I had the tooth extracted and let that heal then the bone graft, let that heal and then the implant.
That whole process took about 8 weeks.
Once you stop Prolia, your bones deteriorate rapidly. PLEASE READ UP ON THAT.
After four weeks off Prolia, I had my first compression fracture. 5 more followed rapidly within weeks. Another two at one time followed by three more all at once.
The hospital had me checked by an Orthopeadic Spine Specialist who explained all this to me, telling me my bones were so soft, he was able to move them.
I've had two surgeries so far. He immediately sent me to their bone clinic where I am now treated by a doctor who specializes strictly in Osteoporsis. I am now on a treatment of Tymlos for two years. I have seven months to go and my bones show remarkable improvement. I've gone from osteoporosis to low bone mass in all measured areas. I am getting annual dexa scans to monitor progress. I'm not sure what I will be taking at the end of two years, but I will have to go on something.
PLEASE do read everything you can find about stopping treatment!!
I will try to find some information for you and will post it this evening.

Let me also mention the snowballing of other issues this has caused. I now have very thin jaw bones and need two implants but the doctor is not sure there will be enough bone to hold them. My face has sagged and I drool. The pain from the fractures was awful. I could not lay down. I slept in a chair. It was too painful to lift my legs to rest them on the ottoman. That led to blood pooling at my ankles, appointments with a vascular surgeon and ultimately vascular surgery. Now I have bulging veins and must wear ugly compression socks forever. I have a huge hump in my back which makes it impossible to lay flat, wear a bra that hooks in the back, sit in a wooden chair or look nice in blouses or tops, (baggy shirts are my new wardrobe). At the completion of my Tymlos treatment, we will begin to consider placing rods in my back to straighten it. I have lost 3" in height and gained a muffin top. I WAS 5'4" and 110# now I am 5'1". You would be amazed at the difference that is. I cannot reach in cabinets. All slacks and dresses have to be altered. I had a very tight, flat stomach. That 3" had to fall somewhere, so it fell right to my waist along with my boobs!
Ask your doctor if you can go off Prolia and on somethimg else before dental work.
I wish you the best and will be thinking of you. Just do your research, get a second or third opinion.
