Teeth whitening is a common procedure that aims to increase the whiteness of discolored teeth. Bleaching products are chemicals such as hydrogen peroxide or carbamide peroxide. The bleach penetrates the upper enamel layer of the tooth and the dentin, the main part of the tooth that is slightly softer than the enamel. The bleach reacts with the colored molecules that cause the discoloration. The dentin then becomes lighter and the teeth appear whiter. Teeth whitening can be done in a variety of ways, either in the clinic or at home, as these procedures provide lightening of up to 10 shades. It is essential to do this under the supervision of experts to ensure the best results and the safety of the procedure.

Teeth Whitening Results:

Results of Teeth Whitening vary before and after from one person to another depending on the health and color of the teeth, healthy teeth free of cavities and with a strong structure respond well to the whitening process and give quick and good results. As for weak teeth, their response may not be quick enough, but with repeated sessions, the desired results can be achieved.

Whitening can provide immediate results, achieving up to 8 shades whiter than the original color. When it comes to whitening techniques, laser technology shows faster results than chemical whitening; the desired result can be achieved in just two sessions, while chemical whitening may require several sessions. It is important to note that the results of teeth whitening are not permanent.

Types of Teeth Whitening:

There are several popular and effective methods for teeth whitening, each offering different benefits to suit the needs of different patients. Below is an explanation of the most common methods:

• Teeth whitening gel: This method begins with the dentist taking an impression of the patient's teeth to create an accurate mouth mold. This mold is used with a whitening gel, which usually contains hydrogen peroxide, an effective bleach. After the mold is prepared, the patient can use it at home on a regular basis, where the gel is placed in the mold and applied to the teeth for a period of two to four weeks, according to the instructions specified by the dentist.
• Laser teeth whitening: This type of whitening is more powerful and effective. The dentist applies the whitening product directly to the teeth, then uses a laser light to activate the whitening ingredients in the product. It usually takes about an hour in the dentist’s office, and provides immediate, noticeable results.

Both methods offer excellent solutions for those looking to significantly improve the appearance of their smile. It is important to discuss your options with your dentist to determine which method is best for your dental condition and desired results.
