A member asked:

How much whiter can laser tooth whitening make my teeth? i think my teeth are a fair bit darker and stained then they used to be, as i've been a heavy coffee drinker over the last 15 years. i'm trying to cut way back on the coffee, but would like to white

Whitening : Whitening is a soft science and results can vary. The nature of your internal tooth color will affect the end result. Without any promise or guarantee it is possible that they will return to the original color or even whiter!

We : We do not know what the result of whitening will be until we try it. It vary widely from patient to patient. The extrinsic ( outside /superficial stain) can be cleaned off relatively easily, and the intrinsic deep stain responds to varying degrees to the exposure to the oxygen released by the whitening agent. We can not predict if your teeth will be returned to a level of color that is similar to what you remember your teeth looked like years ago. They may be lighter. Most patients are delighted with the result dr neil mcleod dds dentistry that lasts -quality thatcounts.

Whitening : Whitening is unpredictable, and some teeth don't respond as much as others. They will change, but how much is hard to know. 3 big factors play a role, gel concentration, frequency and duration. A treatment that is one time, low concentration for 30 minutes will give a different result than 2 weeks with high concentration for several hours. Satisfaction will be up to you.

Most case 4-6 shades: Unfortunately the "laser" has nothing to do with making your teeth whiter. The peroxide is the active ingredient and thats it! if your teeth are on the darker side, from coffee or external stains, you may just have to bleach a little longer, however if the stains are internal stains you may require porcelain veneers to block out the color. A cosmetic dentist can help you make that decision.

Laser whitening: Although "laser" tooth whitening was promoted as a better and faster way to get a patient's teeth whiter, "lasers" are not really used, merely a bright light and that promotion and technique has gone out of favor as most dentists now concede that whitening gels in custom trays to be taken home work just as well and are more cost effective. Discuss options with your own dentist.
