How tooth whitening works?

Tooth whitening, also known as teeth bleaching, is a common dental procedure used to lighten the color of the teeth. There are several methods that can be used to whiten teeth, including professional in-office treatments and at-home treatments.

In-office teeth whitening is typically done by a dentist and involves the use of a bleaching agent, such as hydrogen peroxide or carbamide peroxide, which is applied to the teeth. A special light or laser may be used to activate the bleaching agent and enhance the whitening effect. In-office treatments can typically lighten the teeth several shades in a single visit and may be more effective than at-home treatments.

At-home teeth whitening methods include the use of whitening toothpastes, over-the-counter whitening kits that include a bleaching agent and custom-fit tray, and do-it-yourself methods like baking soda and lemon juice. These methods can be used to whiten teeth gradually over time.

It’s important to note that tooth whitening only works on natural teeth, so whitening will not be effective for teeth that are capped, crowned or have fillings or dentures. Also it is not effective for teeth with a yellow-brown tint which are the result of internal dentin discoloration or tetracycline staining .

It’s always a good idea to check with a dentist before undergoing any teeth whitening treatment, especially if you have sensitive teeth or other dental concerns. They’ll be able to advise you on the best whitening method for your individual needs and help ensure that you achieve the best possible results.

How to preserve whitening results?

There are several steps you can take to maintain the results of your teeth whitening procedure and keep your teeth looking bright and white for as long as possible. Some of these include:

1. Avoiding stain-causing foods and drinks: Some foods and drinks, such as coffee, tea, red wine, and berries, can stain your teeth. To maintain your whitened teeth, it’s best to avoid these types of foods and drinks, or at least limit your consumption of them.
2. Brushing and flossing regularly: Brushing and flossing your teeth twice a day can help remove plaque and prevent new stains from forming on your teeth.
3. Using a whitening toothpaste: A whitening toothpaste can help to remove surface stains and maintain the brightness of your teeth.
4. Touch-up treatments: Some people may benefit from touch-up treatments every few months to keep their teeth looking their whitest.
5. Regular dental check-ups: Regular dental check-ups and cleanings are important for maintaining overall oral health, as well as keeping your teeth white.
6. Quit or reduce smoking: Smoking is known to cause discoloration of the teeth and prolonging the whitening effect.

It’s important to follow the aftercare instructions provided by your dentist or dental hygienist. They will be able to advise you on the best way to maintain your whitened teeth, and they can also monitor your progress and make any necessary adjustments to your treatment plan.
