Can you tell me if private treatment will cost between £7k – 10k?

Q. I have gum disease and my gums are receeding. I have about 4 teeth in my top jaw that need replacing. I will need one grafting and treatment ,i am despartely try to get an idea of costs for bone grafttng and replacing approximately 4 teeth in my top jaw. I already know my 4 top teeth will need grafting as the bone is gone and one tooth is about to fall out and I have lost another already, I have about 5 missing teeth in my bottom jaw which makes it hard to eat. I am trying to put a rough budget together of treatement . Can you tell me if private treatement will cost between £7k – 10k or do you thing my estimation is too low,
