How does teeth whitening work?
Every single tooth whitening product uses the same basic science to achieve results. Tooth discoloration is caused by large pigment and stain molecules that become trapped inside the tooth’s structure (the larger the molecules the darker the teeth appear).
Why would I need my teeth whitened? There are a number of explanations why you might get your teeth whitened. Everyone is different and just as our hair and skin color differ so do our teeth. Very limited people have brilliant-white teeth and our teeth can also become extra discolored as we get older. Your teeth can also be stained on the surface by food and drinks such as tea, coffee, red wine, and black currant, smoking can also stain teeth. Calculus or tartar can also affect the color of your teeth. Some people may have staining beneath the surface which can be caused by certain antibiotics or by tiny cracks in the teeth which take up stains.
Professional bleaching is the utmost usual method of tooth whitening. Your dentist will be able to tell you if you are suitable for the treatment and will supervise it if you are. The active component in the product is usually hydrogen peroxide or carbamide peroxide. As the active element is broken down oxygen gets into the enamel on the teeth and the tooth color is made lighter. This treatment can usually be done within 3 to 4 weeks. However, there are so many products in the market like gel, paste and some kits are available.
Tooth whitening can only lighten your current tooth color. Also, it is only working on natural teeth. It will not work on types of false teeth such as dentures crowns and veneers. If your dentures are stained or discolored visit your dentist and ask for them to be cleaned. Brush your teeth last thing at night and use fluoride toothpaste. Cut down on how often you consume sugary foods and drinks. Visit your dentist regularly.
