A white smile is important to many people, but are teeth naturally yellow?
You may long for a whiter smile, but are teeth naturally yellow? In a world where tooth whitening is increasingly common, especially among those in the public eye, it can be easy to forget what natural teeth look like. A study conducted by OnePoll on behalf of Snow Teeth Whitening showed that up to 61% of Americans wish they could change the appearance of their teeth with a lack of whiteness coming out on top.
So, are teeth naturally yellow? To find out more, we first need to delve into the composition of our teeth. They are made up of three different layers. Enamel is the hardest substance in the human body and forms the outermost layer, dentin is in the middle and the innermost layer is pulp. Not many people realize that it is the dentin, the middle layer of a tooth, which gives it color. For most of us, the dentin is a pale yellow but shades of red or amber are normal too.
Have a look at our feature on 'is teeth whitening safe' for a more in-depth look at the benefits and risks associated with artificial teeth whitening. Our lifestyle choices can also influence the color of our teeth. Smoking can cause teeth to yellow rapidly. The tar and nicotine in tobacco are responsible for this staining effect. Coffee, red wine, chocolate, and fizzy drinks can all contribute to discoloration.
