When whitening, teeth are made of crystalline enamel with micro-cracks. As we chew, these spaces gradually fill up with debris and stains. The teeth whitening process helps remove these stains and debris by exposing these cracks. Most people will see a difference of two to seven shades. While the procedure is not practical for people with dark stains, it is ideal for people who want to get their smile back.
Teeth whiteners are usually made of hydrogen or carbamide peroxide. These whitening agents allow oxygen to penetrate the tooth enamel, making the teeth lighter in color. You can achieve the desired whiteness after one in-office visit. However, the results may vary from person to person and may take several months. During this period, you should refrain from eating or drinking foods that contain tannins. It is also essential to use a mouthguard during this treatment to prevent the stain-causing substances from reappearing.
A single teeth whitening procedure is not sufficient to achieve whiter teeth. A professional treatment will require two or three visits, lasting from two to three weeks. After a single appointment, the treatment results may last for several months, but this can vary. It is essential to avoid foods high in tannins, as this can affect the effectiveness of the treatment. If you have been suffering from teeth-whitening problems, you should consult a dentist for a second opinion.
