Teeth Whitening
Teeth whitening is a cosmetic procedure designed to brighten the color of teeth, making them whiter and brighter. This procedure is commonly performed in aesthetic dentistry to enhance the appearance of a smile by removing stains and discolorations on the teeth. Here is how teeth whitening works in aesthetics:
Initial Evaluation
Before the teeth whitening process begins, a dentist or aesthetic professional conducts an initial evaluation to determine if the patient is a suitable candidate for the procedure. Some individuals may not qualify due to underlying dental issues.
Preparation
Prior to the teeth whitening procedure, the patient's teeth are cleaned to remove plaque and tartar, which could hinder the bleaching process.
Whitening Options
At-Home Whitening: The dentist may provide an at-home whitening kit with custom-made trays and a bleaching gel containing a low concentration of hydrogen peroxide or carbamide peroxide. The patient fills the trays with the gel and wears them for a specified period daily over a few weeks. This is a gradual process.
In-Office Whitening: This method is also known as professional in-chair bleaching. The dentist applies a more concentrated bleaching gel to the patient's teeth and then uses special light or a laser to activate the gel. This process is usually faster and may provide immediate results.
Aftercare
After whitening, the patient may be advised to avoid certain potentially staining foods and beverages (such as coffee, tea, and red wine) for a while to maintain the results. Good oral care, including regular brushing and flossing, is also essential.
Mechanism of Teeth Whitening
The fundamental principle of teeth whitening is based on the use of products containing hydrogen peroxide or carbamide peroxide. These chemicals penetrate the tooth enamel and react with the molecules responsible for stains and discolorations, breaking them down to brighten the teeth's color. However, it's important to note that teeth whitening is not permanent, and the results can vary from person to person, depending on various factors, including the type of tooth stains and dietary habits.
Pre-Procedure Advice
It is highly recommended to consult a dentist or an aesthetic dental professional before considering teeth whitening, as it may not be suitable for everyone, especially those with existing dental issues. Furthermore, teeth whitening should be performed under the supervision of a professional to ensure the safety and effectiveness of the treatment.
