Teeth whitening is an extremely popular cosmetic dentistry procedure that delivers beautiful results quickly and easily. With the latest advanced whitening techniques, we at Dental Associates of Delaware can give you a dazzling, long-lasting white smile in almost no time.
How does it work?
Whitening is a safe and effective way to quickly deliver a dramatic change to your smile. As we age, minerals penetrate the enamel of our teeth and darken them. Certain factors also affect the whiteness of our teeth.
We have different options available for whitening teeth, but generally it is accomplished by applying a bleaching gel directly to the teeth. The active ingredient in this gel, usually hydrogen or carbamide peroxide, breaks down and forces oxygen into the enamel and dentin of your tooth structure. The oxygen breaks down the stains and makes teeth whiter, without hurting the structure of the teeth.
Factors that affect the whiteness of your teeth include:
Some staining and discoloration is natural as we age since we accumulate stains from foods and beverages and other elements over the years.
- Tobacco Use
Cigarettes, cigars, pipes, and smokeless tobacco all stain teeth, especially after long-term repeated exposure. These stains can be minimized and often virtually eliminated by professional dental whitening. However, continued use after the whitening process will affect how long the whitening lasts.
- Food and Beverages
Some foods, like colas, red wine, tea and coffee, stain teeth, especially after long-term repeated exposure. These stains can be minimized and often virtually eliminated by professional dental whitening. However, continued use after the whitening process will affect how long the whitening lasts.
In some cases, medication can cause stains or tooth darkening. These stains can be some of the most stubborn and difficult to remove. Fluorosis, a condition caused by too much fluoride, can cause discoloration, as can tetracycline and some antibiotics used during childhood years. We can explain how professional whitening can help in these situations.
How long does it take?
The length of time the bleaching process takes depends on the method used and the type of stains being removed. In-office procedures typically take one to three hours. With take-home whitening procedures, results can typically be seen in as little as three to four days, with the final result commonly taking about two weeks. Of course the degree of staining and the level of desired whiteness are factors in the total time.
Is whitening for me?
Whitening produces results in over ninety percent of patients, and it doesn’t hurt teeth. Different factors will affect the process, and some people are better candidates than others. In general, yellow and light brown teeth, stained over a period of years make excellent candidates, while darker brown or grayish stains require special techniques. Whitening will not lighten artificial material in your mouth like bonding, fillings and veneers. Those with sensitive teeth, damaged teeth, gum disease, and pregnant women are encouraged to discuss their conditions with us.
What are the different whitening options?
We offer two types of whitening, in-office whitening and take-home whitening kits. Both offer excellent results. The difference between the techniques involves the strength of the whitening gel and the length of time it remains in contact with the teeth. Some techniques are better than others on particular types of stains. We will explain which method is best for you, and could suggest either or a combination of both methods for the best possible results.
- Take-home whitening kits are an affordable and effective way for many people to achieve excellent whitening results. After preparing your teeth for whitening, we will take impressions of your teeth and fabricate plastic trays molded specifically to fit your mouth. At home, you will fill the trays with the whitening gel and fit them over your teeth. The trays hold the gel in contact with the teeth and are worn for a specified period of time. Some treatments are specifically designed to be worn overnight while you sleep. The trays are typically worn daily for ten to fourteen days (or nights), or until the desired whiteness is achieved.
- In-office procedures sometimes called laser bleaching or power bleaching, are safe and effective methods to whiten teeth in the fastest way possible. Most in-office whitening takes one to three hours, including preparation time. Many patients prefer in-office bleaching because it offers instant results. Once the teeth are prepared for whitening we apply the gel to the surface of the teeth and it remains on the teeth for about an hour while you relax comfortably in the chair. In some instances a laser or special light is used to assist the gel in the whitening process.
What is Zoom whitening?
Zoom whitening is offered as an in-office system at our Hockessin location. Most people make good candidates for the in-office procedure which produces excellent results in little more than an hour. This involves application of a hydrogen peroxide gel and the unique patented Zoom light. Once your dentist has prepared the teeth, they apply the gel and projects the zoom light directly on the treated teeth for about an hour.
Why is whitening from us better than using an over-the-counter product?
Over the counter products are not as effective or long lasting as the techniques offered by us at Dental Associates of Delaware. Additionally the trays that hold the whitening gel are not custom fitted, and could allow leakage that irritates gums.
What preparation do we do before whitening the teeth?
We will thoroughly examine your teeth to determine if you are a good candidate for whitening, and what is the best method for your needs. A dental cleaning is always a good idea to make sure that the whitening gel can easily contact the clean, prepared surfaces of your teeth. We will also repair any damaged or sensitive teeth and address any cavity or gum problems before proceeding with the whitening procedure.
What results can I expect?
Whitening produces results in over ninety percent of patients, and it doesn’t hurt teeth. Typical results can produce a change of several shades of whiteness, lasting three to five years. Different factors affect how long the process takes, what method is used and how long the whitening lasts.
Is whitening safe?
The American Dental Association has approved whitening products, and clinical trials and studies have found them to be safe and effective. Most people suffer no side effects from whitening procedures, but some sensitivity to hot and cold foods is possible. This typically lasts for less than 48 hours.
