Why Laser Teeth Whitening Results May Differ Per Person

When over-the-counter strips and solutions do not produce the desired results, many patients turn to the dentist for laser teeth whitening. While it is very effective for many, it is not a one size fits all solution, and the results of the procedure differ from patient to patient.

What to expect from laser teeth whitening

Dentists can use lasers to speed up the chemical reaction of a strong whitening solution. This allows patients to get whiter teeth in fewer whitening sessions over a shorter period. It does not, however, react the same to every patient's teeth.

Qualifying for laser teeth whitening

One of the first steps in the whitening process is determining whether the laser procedure will be effective. Some patient's teeth are naturally dark, while others are darkened by staining. In the case of a patient with naturally dark teeth, the procedure will not be as effective. Patients with sensitive gums may also be disqualified because the bleaching solution used during laser teeth whitening can be irritating.

How well does it work?

Results vary, but patients can expect significantly whiter teeth from the procedure. Laser teeth whitening's reputation is well deserved. It is important to note, however, that the patient is responsible for maintaining the whitening. Teeth can be especially sensitive both to temperature and staining for a week or two after the procedure. Some foods and drinks that patients must avoid are listed below.

• Coffee and tea
• Red wine
• Red sauce
• Blackberries and blueberries
• Soda and energy drinks
• Soy sauce
• Candy

Even after the one to two-week period of sensitivity, patients need to keep in mind that laser teeth whitening does not prevent the teeth from fading back naturally. This means that aftercare, in the form of in-home whitening trays, is required to maintain the results.

Alternatives

There are many alternatives to laser teeth whitening, and a dentist can help advise patients on choosing the right one. Over-the-counter whiteners are not as strong as the office has, but they are peroxide-based and can be effective for some. Whitening toothpastes can help whiten the surface of teeth but do not penetrate deeper. Whitening strips and gels also contain peroxide, but they are applied differently and the speed of results varies between products.

When using over-the-counter alternatives to laser teeth whitening, it is imperative that patients follow the directions. Peroxide, which is the active ingredient in most products, can be harmful if left on the teeth and gums for too long. A dentist can help recommend the right product for the patient's teeth. Some patients may also be eligible for dental veneers, which cover cracks and inconsistencies with a natural-looking porcelain layer.
