The truth about teeth whitening

Posted on September 23, 2016 | By: Hope

What causes teeth to stain?

Dark foods and liquids, that are consumed on a regular basis, can cause staining.  Dark fruits or vegetables, such as: Blueberries, blackberries, spinach, and kale. Coffee, tea, soda, and tobacco products. Over time, the dark pigments can get into the inner layers of the enamel, causing teeth to look more yellow/brown.

How to avoid getting stain:

While eating or drinking things with dark pigments, drink/rinse water to keep the pigments from settling on your teeth. Drink dark liquids through a straw, to avoid the front teeth.  You can also brush your teeth after, reduce risk of stain.

How to whiten your teeth:

You can use many different types of whitening products to whiten teeth. There are whitening toothpastes and mouth rinses, whitening strips, and professional whitening trays. Most of these products contain Carbamide Peroxide or Hydrogen Peroxide, which act as the whitening agent. Results can vary from person to person. Everyone’s teeth are different, and will have different results with different products.
-Toothpastes and  mouth rinses will have the lowest amount of whitening agent. They work well to reduce staining on the surface layer of the enamel.
-Over the counter White Strips contain between 10-15% peroxide. This whitens the inner layers of the enamel, resulting in a whiter smile that stays white longer.
-Professional whitening trays come with gel that can range from 18-35% peroxide. This will whiten  the deepest layers of your enamel, giving you the best results that will last the longest.


Sensitivity is a common side effect of whitening.  The whitening product cleans out the pores of the enamel, opening up the enamel tubules. The tubules lead to the nerves of your teeth, and if opened, can cause the nerves to get stimulated. To reduce risk of sensitivity while whitening, use a sensitive toothpaste 2x day. Always brush with sensitive toothpaste after using a whitening product.


Whitening your teeth is completely safe, as long as the product is used as directed!
