What is bleaching/ teeth whitening
Tooth whitening can be a very effective way of making your teeth look whiter and brighter without removing any of the tooth surface. It cannot make a complete colour change, but it may lighten the existing shade. Brushing and flossing are everyday ways to keep your teeth bright, white and healthy. Still, if you might feel like your smile is lacking some sparkle or is more yellow than it used to be, you’re not alone.
Why do my teeth look yellow now?
Over time, your teeth can go from white to not-so-bright for a number of reasons:
- Food and Drink -If you drink a lot of Coffee,tea and red wine then you may probably have darker teeth. they all have intense color pigments called chromogens that attach to the white, outer part of your tooth (enamel).
- Tobacco Use Two chemicals found in tobacco create stubborn stains: Tar and nicotine. Tar is naturally dark. Nicotine is colorless until it’s mixed with oxygen. Then, it turns into a yellowish, surface-staining substance.
- Age Below the hard, white outer shell of your teeth (enamel) is a softer area called dentin.dentin is yellow in color. Over time, the outer enamel layer gets thinner with brushing and more of the yellowish dentin shows through.
- Trauma If you’ve been hit in the mouth, your tooth may change color because it reacts to an injury by laying down more dentin, which is a darker layer under the enamel.
How Does Teeth Whitening Work?
Teeth whitening is a simple process. Whitening products contain either hydrogen peroxide or carbamide peroxide. These bleaches break stains into smaller pieces, which makes the color less concentrated and your teeth brighter.
