Tooth whitening can be a very effective way of lightening the natural colour of your teeth 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 Did My Teeth Change Color?
Over time, your teeth can go from white to not-so-bright for a number of reasons:
Food and Drink
Coffee, tea and red wine are some major staining culprits. What do they have in common? Intense color pigments called chromogens that attach to the white, outer part of your tooth (enamel).
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.
Below the hard, white outer shell of your teeth (enamel) is a softer area called dentin. Over time, the outer enamel layer gets thinner with brushing and more of the yellowish dentin shows through.
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 one of two tooth bleaches (hydrogen peroxide or carbamide peroxide)
. These bleaches break stains into smaller pieces, which makes the color less concentrated and your teeth brighter.
How can I look after my teeth once they have been whitened?
You can help to keep your teeth white by cutting down on the amount of food and drinks you have that can stain teeth. Don't forget, stopping smoking can also help prevent discoloration and staining.
