Best Method for Teeth Whitening That is Permanent Other Than Strips, Gels and Pastes?

In my personal opinion, First: we are talking about yellow teeth (or you are saying you have yellow teeth), that it doesn't matter any bleaching system you chose, they will eventually return to the yellow color you already know you don't like. If you do not want to struggle with bleaching systems, why not get your porcelain veneers with a replica of your natural teeth (if you like them so much- the contour and shape of your teeth as you mention above) and if not, you can change it to any shape. And the best thing is that you will always have the white teeth you want and you will have what I call a "Hollywood smile" As you ask, veneers cost $450 US each,  and I can make your complete smile makeover in 10 days. We live in an era where you can change any part of your body, if you want it and if you can do it? why not? Techniques and materials are very advanced and veneers are fine laminates of porcelain that are super strong and the shaving of teeth is not too big. I do not know how old are you, but the years you will have above, you can live them with the smile you want.

The best way to keep a  newly whitened smile bright is by avoiding smoking and eating foods like coffee, wine and chocolates that stain teeth. If it can stain a white t-shirt, it will stain your teeth. For this reason, no whitening treatment is truly permanent. Your next best option is to retouch your teeth every few months when they start to lose their luster. My office offers a whitening for life program to our patients. After the initial whitening treatment, patients receive bleaching gels every six-months to keep their teeth white. Best of luck in keeping the sparkle in your smile.
