Everybody wants to have “pearly whites” and a lot of people will do whatever it takes to get them shining bright and white. The real question now though, is, how safe is it to whiten your teeth? I looked into this and found some interesting things about this topic.
What exactly is a tooth?
Teeth are used to bite and chew food (first step in digestion of food). The outer layer of a tooth is made of enamel, followed by the dentin, pulp, cementum, and eventually nerves the root ending. Adults have 32 calcified teeth that are hard and very strong.
Why do teeth yellow?
Some people are just born with slightly yellow teeth, but if this is not the case there are other reasons for yellowing as well. Overtime teeth yellow because of staining from food, drinks, and other substances introduced to the mouth. It is completely normal for teeth to become slightly yellow over time.
Is it safe to whiten teeth?
Many dentists say that teeth whitening is safe if it is done correctly. Because of the different chemicals in “at-home” whiteners there are some risks to using them too often. If you use whitening strips more than the appropriate time then teeth can become very sensitive. Sensitivity is the number one side effect of whitening teeth.
When you have stains on your teeth it is because stain has formed in because the tubes (enamel rods) in your tooth begin to get plugged up with organic matter. It is absolutely impossible to brush away any of the stain that has now formed on your teeth.
