Brushing and flossing are everyday ways to keep your teeth bright, white and healthy.
Still, if you feel like your smile is lacking some sparkle or is more yellow than it used to be, you’re not alone.
Wondering 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.
Tooth darkening can be a side effect of certain antihistamines, antipsychotics and high blood pressure medications. Young children who are exposed to antibiotics like tetracycline and doxycycline when their teeth are forming (either in the womb or as a baby) may have discoloration of their adult teeth later in life. Chemotherapy and head and neck radiation can also darken teeth.
How does teeth whitening work?
Stains on teeth are classified in two categories: extrinsic or intrinsic. Extrinsic are stains that appear on the surface and intrinsic stains live between the tiny cracks in your enamel. Whitening toothpastes and mouth rinses may be able to remove some of the extrinsic stains on your teeth, but only teeth whitening agents can remove those stubborn outer stains and the unsightly intrinsic stains that cause your teeth to look discolored.
Our whitening kits contain an active whitening ingredient that penetrates your enamel to get to discolored molecules. Oxygen molecules from the whitening agents react with the discolored molecules in your teeth, breaking the bonds that hold them together. The oxygen molecules spread, whitening the entire tooth.
As a result, you are left with a brighter, whiter smile.
