Replacement of missing tooth. And good!

Please don't plan such treatments based on your assumptions. You will be playing with your health if you make such decisions which are not based on proper facts and guidance by a specialist. The basic rule that we go buy in dentistry is--- "it is most important to save what is remaining in the mouth rather than going for the meticulous replacement of what has been lost". 3 teeth can be replaced by many techniques including removable dentures or bridges of implants. But removing 25 teeth to replace 3 teeth would be a very very impractical and wrong step and I don't think any dentist will do that for you even if you ask for it especially given your age. And other thing to understand is that a denture is not cheap because you should correlate the cost of the treatment with your own health and you will realise that in the long run it will prove very very costly. And coming to the point that it is good, please understand that modality of tooth replacement can be better than the natural tooth being retained. Regards.
