teeth whitening...?

hello, I want to make whitening, but i wonder, is it lost of money to do it at dentist or it deserve it? do you think dentist or whitening products? which gives better result ? is it the same ?

Whitening is great! In my professional opinion, I would recommend seeing your dentist to have him evaluate which procedure is best for you. Not all patients are good candidates for whitening, certain stains are difficult to whiten, also if you have a lot of crowns or tooth colored fillings on your anterior teeth you might not want to whiten. Only YOUR teeth will change color, so you will end up with darker crowns and fillings when the rest of your teeth lighten. Teeth can only get so white, a lot of which is determined by the color of dentin beneath the tooth enamel. People with very very white teeth usually have veneers. If your teeth are severely discolored you would best benefit from the in office whitening procedures. These procedures are a bit more pricey but lighten the teeth more shades than OTC whitening products. If your teeth are only slightly discolored, products such as crest white strips work great! Don't waste your money on expensive in office procedures if your teeth are already pretty white, they will only change a few shades. In offices procedures such as trays or zoom whitening generally change your teeth 5-8 shades where as OTC strips only change your teeth about 3-4 shades. It's also important to note that you should only get whitening toothpastes that have hydrogen peroxide in them. Many whitening toothpastes are only "whitening" because they have abrasive agents w/in the toothpaste which over time are damaging to enamel. Hope this helps!!
