Which teeth whitening product is the most effective, safest and still affordable?

I appreciate any recommendations if you have used any and have found it effective.

Honey, you have gotten two spam/advertisement responses so far. Let me see if I can give you some real information. First of all, the "most effective" is not the least expensive. That's the sad truth here. So, what I suggest is that you try the inexpensive treatments first and see if they work for you. If they do, then you don't have to worry about the high-priced stuff. The cheapest whitening product around is plain old baking soda. Arm and Hammer or any store brand will do. Put a little in a dish, add a couple of drops of water, and mix it into a paste, then brush normally. This will whiten your teeth, but don't expect it to work over night. It takes several weeks before you will notice any results. You can make the baking soda treatment a bit more effective by getting some hydrogen peroxide at the drug store and using a few drops of that in place of the water. The next level up from the home-made versions is to use the whitening strips and toothpastes that are sold in drug and grocery stores. Most people find that Crest White Strips are the best of these. Try them if baking soda and peroxide don't work. And look for sales. Where I live, they seem to go on sale about once a month or once every two months. Since the Crest strips aren't cheap, it makes sense to wait for a sale if you can. But if you really want the most effective treatment, you will have to go to a dentist. They have products there that can whiten much faster and do much more. They are quite expensive, unfortunately. But if you want the most whitening possible, that may be the way you have to go. Try the other things first. I hope this helps, and I wish you good luck!!
