Tooth Bleaching Before Dental Crowns from Your Dentist

If you require crowns to be placed, it is a good idea to evaluate how you feel about the color of your existing teeth before beginning the process. If you like the color of your teeth, the dentist will then match the crowns to that color. On the other hand, if you feel you would like to whiten or lighten your teeth, it is a good idea to communicate this to your dentist beforehand about tooth whitening. Once the final restorations are made, it will not be possible to change their color without redoing them.

At-Home Teeth Bleaching

If you desire whiter teeth before the crowns are placed, the best way to achieve this is to talk to your dentist about at-home teeth whitening. With this procedure, custom-fitted plastic trays will be made for your teeth and you will be given some small tubes of dental bleaching material. Your dentist will show you how to place a small amount of bleaching material in the tray and then place the tray in your mouth. The tray is then worn for one to two hours in the evening, depending on the type of material. The biggest advantage of this method of teeth whitening compared to procedures that are done in your dentist's office is, that you are the one who can control how white your teeth will be. Since you are the one in control, you can stop bleaching whenever you feel you have achieved the desired color. The typical bleaching time is one and one-half to two weeks, but it may be longer.

Sensitivity to Tooth Bleaching

Your teeth may become sensitive to cold air or liquids during the tooth bleaching process. This is normal and will subside and finally go away when you stop bleaching. There are a couple of things you can do to decrease this sensitivity if it arises during the tooth whitening process. One is to only bleach every other night. The other is to have your dentist prescribe for you a fluoride gel that you can place in your custom bleach trays every other evening. The fluoride acts to decrease the sensitivity by coating or sealing the tooth surface. It will not affect the color of your teeth. This is the most reliable way to decrease sensitivity while you bleach. Once you get your teeth to the desired color, your dentist will have you wait about three to four weeks before taking a color match of your new white teeth in order to make the final restoration. During this time, the color of your teeth will be stabilizing.

Once the Restorations Are Placed, What Can You Expect?

Teeth bleaching is a very predictable method for getting white teeth, but the results will not last forever. Since the restorations were placed when your teeth were at their whitest, you will most likely find that in one and a half to two years, the restorations may begin to appear lighter than your natural teeth. This result is to be expected. It is not caused by a change in color of the restorations, but rather by your own teeth getting darker. At this point, all that is required is to, once again, bleach your natural teeth until the color is evened out. Usually, this only requires bleaching a couple of times. After the color is evened out, you can then expect to have the color stability last for another one and a half to two years.

Teeth Whitener Options: Different Ways to Brighten Your Teeth

"Tooth whitening" is a broad term, and it's sometimes hard to know what's the right tooth whitener for you. Wondering what your options are?

• Teeth whitening or laser bleaching at the dentist's office
• At-home bleaching kits provided by your dentist
• Over-the-counter tooth whiteners sold at pharmacies, grocery stores, etc.

You'll get the most dramatic results if you see your dentist for instant whitening. Dentists apply a powerful bleaching agent to your teeth for a short period of time. (In laser teeth whitening, the dentist uses laser light to activate the bleaching agent.) The appointment typically takes about an hour and can lighten teeth by a number of shades. For deep-down tooth stains, multiple sessions may be required to achieve maximum brightness.

Your dentist can also give you a kit that allows you to bleach your teeth in the comfort and privacy of your own home. Your dentist will take molds of your teeth to create customized dental trays; made of thin plastic, the trays slide over your teeth and provide a tight seal. Each day (or night), you'll put a small amount of bleaching paste or gel in the trays, then slide them over your teeth. Most people wear the trays for about half an hour a day for two weeks.

If you're skipping the dentist and buying tooth whiteners at the store without a prescription, you're not getting the same type of whitening offered by cosmetic dentists. These products will do the job, but they will never be as effective as what you'll get from a dentist. By law, over-the-counter tooth whitening products cannot use as strong of bleaching agents as those used by licensed dentists.

These commercial products come in a number of forms. Whitening toothpaste has been around for a long time, and whitening strips have become increasingly popular. They may provide a bleaching gel that you paint on your teeth or apply via one-size-fits-all bleaching trays.

In considering your teeth bleaching options, you should ask yourself how much money you're willing to spend and how many shades whiter you want your teeth to be. Your dentist can also help you decide what's the right method for you.
