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.

Tooth Whitening - Why Are My Teeth Discolored?

If you're embarrassed by your discolored teeth, you're not alone. There's a reason cosmetic dentistry, including teeth whitening, is a multibillion dollar industry. We all want brighter, whiter teeth. While it would be nice to get the smile you'd love naturally, that just isn't an option. So, who's to blame? Why are you struggling with tooth discoloration to begin with? Good news - it may not be your fault!

Common Causes of Tooth Discoloration

There are a number of causes of potential tooth discoloration, and some are completely unavoidable on your part. While the precise cause of your tooth discoloration may be difficult to peg down, chances are one or more of the following causes are to blame.

• Food and Drinks. You may have heard that coffee, tea and soda can stain your teeth, but did you know certain veggies, like potatoes and apples, can stain them as well?
• Tobacco. This is a given. Smoking and chewing will not only discolor your teeth, but can also cause gum disease or contribute to oral cancer (among other health conditions).
• Poor Dental Hygiene. If you don't want to give up your morning coffee or kick your smoking habit, then you're going to have to try to compensate with excellent dental care. Regular brushing and flossing can reduce the odds that you will stain your teeth. Regular check ups and cleanings are critical, too.
• Disease. Ahh… finally, we're discussing possible causes for tooth discoloration that aren't your fault. Several diseases that affect tooth enamel and dentin can lead to tooth discoloration. What's more, treatments for certain conditions, such as chemotherapy to fight cancer, can discolor your teeth. If you're pregnant while suffering from one of these ailments or undergoing one of these treatments, the teeth of your developing child may be affected as well.
• Medications. Certain antibiotics, such as tetracycline and doxycycline, can discolor your teeth, particularly if used before the age of 8. Mouth rinses and washes containing chlorhexidine and cetylpyridinium chloride can also stain teeth, while antihistamines (like Benadryl), antipsychotic drugs and antihypertensive medications also cause discoloration.
• Genetics. When all else fails, blame mom and dad.
• Age. Nothing escapes the affects of age - not even your teeth.
• Environment. Excessive fluoride from environmental sources, such as naturally high fluoride levels in the water, can contribute to discolored teeth.

While there are many causes of tooth discoloration, today there are also many ways to get whiter teeth.
