Both my children were born missing some adult teeth. Only the oldest has has her implants at this point, but they were definitely the right route to choose, and we anticipate doing the same thing for the younger when she's ready. Comments on my experience:
Be aware that an implant is a several-step procedure. You don't just go into the office one morning and walk out at lunchtime with an implant.
Our daughter had her wisdom teeth out /the baby tooth that was "holding the spot" out / the implant put into her jaw all on the same day. She was put to sleep for this procedure. The implant itself is kind of like a screw that goes into the jaw, but it is full of holes. The bone grows through the holes, making it a permanant part of the body. She lived with the implant and a "cover" -- I forget the real word -- for a couple months.
After that, the dentist x-rayed her and said that her jaw was accepting the implant perfectly, and he okayed us to go back to the dentist.
The dentist removed the "cover" and placed a "fake tooth" over the implant.
The process was time-consuming (I want to say it was something like 4 months between the implant going in /process being finished, but worthwhile. The tooth has given her NO TROUBLE in the two years she's had it. I don't notice that it's not a real tooth, and she treats it just like a real tooth as far as brushing it, etc. It requires NO EFFORT on a daily basis.
I understand the implant is for life, but the fake tooth eventually will need replacing -- but it should have a decades long lifespan before it needs replacing.
The cost was high: All told, and I think this included the wisdom teeth, I think I paid over 4K.
