No. Porcelain is ceramic glass, it is what it is.  The only way to change them is to have them redone.

There aren't any and none of them are approved by the ADA.  The best way to whiten your teeth is by going to see your dentist.  The only whitening systems for home use that have been approved by the ADA are Colgate Platinum Daytime Professional Whitening System, Opalescence, and Nite White.  All of which can only be obtained from your dentist.

Be careful with those white strips.  The peroxide they use damages the tooth enamel.  I would say get Go Smile instead.  More expensive, but better results and no tooth damage.

Abbrasives! Beware, these so called whiteners will typically destroy the enamel coating on your teeth, exposing them to infections and eventaully your teeth will rot.\nWhen you brush with these abbrasives it is similar to brushing with sand, you are litteraly grinding the surface of your teeth off!

i agree with the dentist here. you may as well save yourself the trouble of using them in the first place. i myself have used the tray system with my dentist and it wasnt all that costly. probably the most cost effective way to get your teeth whitened with very good results. and yes no whitening technique works on any restorations (crowns, bridges, fillings etc). best thing to do is whiten then replace your restorations to match the color of your teeth after whitening. good luck

I work for a dentist the best thing to do is just keep your teeth brushed good. If you use any thing to make them white you will have two diffrent shades when you have the braces removed.

The crest whitestrips premium are very good! I used them and my teeth were noticably whiter after just 2 uses. After using the whole box, it looked like I had the professional whitening done.

Actually, there isn't a tooth paste that really whitens. They all say they do, but it's false advertising. They don't carry the bleach that is needed to whiten your teeth. Either go with Crest Whitening strips or get it done with your dentist.

It's not ADA approved.  No whitening systems over the counter are approved by the ADA.  See your dentist for whitening your teeth.

As long as you oral hygiene is good, you don't have to worry much. In the absence of certain medicines, smoking, tea, coffee, curry, etc. it is a slow process. If your concern is based on esthetics, then better start looking for affordable teeth whitening system/product to address it.

Hi, Crest white Strips will take the enamel(sp?) of of your teeth. The enamal protects your teeth. I recommend not to use them. It works beutifully, but here are some homemade methods that are great!\n\n1)It's not a myth...baking powder works like magic, I personally have used it. Baking soda is a natural bleach, so it actually can not do any harm for you!\n\n2)Have you tried hydrogen peroxide (Sp?). It too works great. If you mix them together on your toothbrush you will have a white smile. (It is recommend not to use the hydrogen poroxide more than 3 times a week)\n\nAnyways, give it a try...and I hope it helps! \n\nP.S. By the way many people use lemon juice. DO NOT use this. It is too citrusy for your teeth and can eat away at them. Good luck! :)

Crest Whitestrips can make your teeth very sensitive and also they are not approved by the ADA (American Dental Association).  There are no products you can purchase over-the-counter that is approved by the ADA.  The best way to whiten your teeth is to see your dentist as they have the only whitening products that are approved by the ADA and also so they can monitor you through your treatment in the event any problems arise.  Also, whitening toothpastes do not change the shade of your teeth and are very abrasive and can cause potential damage to the enamel of the teeth.

Not necessarily.  Your teeth could just be stained.  The colour of your teeth may be dependent on a number of things like diet or hygiene.

No. Try getting a mouthwash like listerine plus whitening. It works trust me.

My friend has the WHITEST teeth I have ever seen. She used Crest White Strips and Crest Vivid White toothpaste.

You just need to call the dentists in your area and ask them if they accept this for teeth whitening.  My question is why not just go buy a box of crest white strips as this is what my dentist recommended if I wanted to whiten my teeth.
