Teeth Whitening

There are many products and techniques available for patients who want to achieve a brighter smile, and with so many options available, it can be difficult to choose the method that is right for you. The best way to begin any teeth-whitening regimen is to schedule an appointment and talk to your doctor about the differences between in-office professional whitening and at-home whitening.

In-office teeth whitening

The first professional option is commonly referred to as in-office whitening. This procedure is performed in a dental office. During an appointment, your dental professional will apply a whitening gel to the surface of your teeth. The entire office visit generally takes about 90 minutes and you will be able to see results immediately.

At-home teeth whitening

Tray whitening

Tray bleaching is a type of professional whitening that uses custom-made trays and whitening gel only available through your dentist. The whitening gel is placed in custom-fitted trays that fit perfectly over your teeth. As the peroxide in the gel breaks down, hydroxyl radicals help whiten stained teeth. Unlike strips, this process whitens all your natural teeth and may contain ingredients intended to provide maximum comfort. At-home professional tray whitening generally takes ten to 14 days, although you may notice results in as little as three to five days.

Paint-on teeth whiteners

There are many over-the-counter teeth whitening options, and one type of readily accessible whitening product is commonly referred to as a “paint-on” teeth whitener. Paint-on whiteners can be purchased over the counter and generally are less expensive and less effective than whitening strips or professional options. Paint-on teeth whiteners consist of a gel that is applied to the tooth using a small brush. Paint-on whitening gel hardens into a film that coats the teeth, and dissolves in the mouth. As with any teeth-whitening regimen, it is wise to consult with a dental professional before use.

Teeth-whitening strips

Teeth-whitening strips are thin, flexible plastic (polyethylene) strips with a thin film of hydrogen peroxide on one side. Whitening strip kits come with two types of strips: strips for the upper teeth and strips for the lower teeth. The whitening agent is applied by placing the strips across your teeth and gently pressing the strips to ensure contact with all your teeth. Teeth-whitening strips are typically worn for 30 minutes a day, twice a day. The duration of treatment will vary.

Whitening toothpaste and mouthwash

The least expensive options are whitening toothpastes and mouthwashes. Designed to have “whitening” capabilities, toothpastes and mouthwashes work to remove surface stains using mild abrasives. However, unlike the materials used in professional whitening procedures, these products do not lighten the actual color shade of the tooth. Whitening toothpastes affect surface stains and will mildly lighten your teeth.

Is whitening right for you?

Whitening works best on yellowish surface stains from coffee, tea, red wine, tobacco and aging. It is less effective on gray or brown stains, or on discoloration from medications or an injury. A few things to know before you start:

• See us first. Cavities, worn enamel or gum disease should be treated before whitening, and a professional cleaning removes surface stains so the whitener works evenly.
• Crowns, fillings and veneers do not whiten. If you have restorations on front teeth, whiten first and then match any new work to your brighter shade.
• Sensitivity is common and temporary. Your teeth or gums may feel sensitive for a few days. A toothpaste for sensitive teeth and taking a break between sessions help.
• Look for the ADA Seal of Acceptance on at-home products, which means they have been tested for safety and effectiveness.

Making your results last

Whitening results typically last from several months to a few years, depending on your habits. Rinse with water after coffee, tea or red wine, avoid tobacco, brush twice a day and keep up with your checkups. If you whiten with custom trays, keep them: they can be reused for occasional touch-ups.
