All implants are private dentistry. The NHS will surgically implant a tooth that has been knocked out but they don't do implants as such. Expect to pay 2 to 3 thou per tooth, with a discount for having two done in one session. My DH has had a few and they have been very successful. I have had two, one brilliant and one failed. the failure was my fault, I waited too long and there wasn't enough bone left in my upper jaw.
The key to success is an experienced dentist, good bone density and careful after surgery care.
I would only go to a dentist i trusted or to one that someone I knew and trusted trusted. I would NOT go abroad for it.
My dentist operates a system whereby if the first implant fails to integrate with your jaw, he does a second one at no extra charge. Sadly. as i said mine failed because of a lack of bone. When the first one failed I got an infection over the weekend which was a symptom, NOT a cause, of the failure. The dentist isn't open and the NHS did not want to know as they don't do implants...would only give pain relief advice, not even antibiotics. That's why i wouldn't go abroad, at least if you have it done in the UK, you can get support during the process.
With my man, including simple extraction it takes 3 to 4 months.
consultation, treatment plan discussed and agreed and charges made clear. initial moulds taken.
Tooth out, 4 to 6 weeks healing
Implant in 4 to 6 weeks healing, maybe longer
Tooth post screwed into socket. Final mould made for tooth. 2 weeks
Tooth cemented onto post and final adjustment made.
If I needed another one in the future and could afford it, if the bone was good enough i would have another one. its not pleasant, neither was it agony.
