Our teeth can discolor through the years as our enamel wears down. The wearing down of enamel allows dentin, a yellow color substance that makes the core of our teeth, to show through. This is what gives our teeth a yellowish tint. Teeth whitening helps restore teeth to a shiny white color through the use of bleach.
Teeth whitening methods
There are two popular teeth whitening options available through your dentist. The first, in-office teeth whitening, produces a significant color change in your teeth in a short amount of time, usually within an hour. The procedure is done at the dentist's office by applying a high-concentration peroxide gel on the teeth after they have been protected with a special shield.
The second method, involves the use of take home whitening kits. These whitening kits are purchased from your doctor for use at home. The strength of the gel used in these kits is lower than that used for in-office bleaching, and thus the gel can be applied for longer periods of time. Usually the trays are worn a couple hours a day or overnight for a few days or weeks depending on the product.
Its best to consult your dentist to understand which whitening option is best for you.
Frequently Asked Questions
Q. What types of teeth whitening options does your Hewlett dental practice offer?
A. At our Hewlett, NY dental office, we offer in-office professional whitening that delivers dramatic results in about an hour using high-concentration peroxide gel. We also provide custom take-home whitening kits with lower-strength gels and trays designed specifically for your smile, allowing gradual whitening over several days or weeks.
Q. How long do professional teeth whitening results last?
A. Results vary based on individual habits (like coffee, tea, smoking), but most patients experience noticeably whiter teeth for 6 months to a year or longer. Occasional touch-ups and good oral hygiene help prolong your bright smile.
Q. Is professional teeth whitening better than over-the-counter products?
A. Yes. Professional whitening at the dentist uses stronger, dentist-supervised formulations and is custom-controlled for safety and effectiveness. This typically results in faster, more consistent whitening than over-the-counter products.
Q. Does the whitening procedure hurt or cause sensitivity?
A. Some patients may feel mild sensitivity during or after treatment, especially if they already have sensitive teeth, but it is usually temporary. Our team will recommend strategies to minimize sensitivity both during and after treatment.
Q. Am I a good candidate for teeth whitening?
A. Most adults with healthy teeth and gums are good candidates. A dental examination is recommended first to ensure your oral health is stable and to determine whether in-office whitening or a take-home option will best meet your cosmetic goals.
Q. How long does a professional whitening appointment take?
A. In-office whitening treatments generally take about 60 minutes, making it a great option for busy patients who want fast, visible results.
Q. Can whitening improve all types of tooth discoloration?
A. Professional whitening works best on stains caused by diet (like coffee, tea) and aging. However, intrinsic stains (from medications or trauma) may respond differently, and your dentist will advise if whitening will meet your expectations.
Q. How should I prepare for teeth whitening at your Hewlett dental office?
A. You don’t need extensive preparation, but we recommend a routine dental cleaning first and discussing any sensitivity or cosmetic goals with our team so we can tailor your treatment plan.
