You may have teeth that are no longer the white you once remember or would like to have. Truth is the discoloration or yellowing of our teeth is a natural occurrence that happens over time to most adults at some point or another. Most people are aware that there are over the counter products such as whitening strips, toothpastes, and mouth trays that all claim to whiten teeth. Advanced Dental also offers in-office whitening as well as take-home whitening kits that are more effective than anything you can buy at the drug store. There is a science behind why our teeth discolor and we will discuss it below.
Why Teeth Turn Yellow
When we were born our teeth started out sparkling white. So why the change? The answer lies in the enamel of our teeth. Enamel is the porcelain-like protective surface on our teeth that defends our teeth from the effects of chewing, gnashing, trauma and acid attacks caused by sugar. As we age the enamel begins to hold stains within its pores and becomes more transparent. The transparency of our teeth allows the yellow color of dentin, the tooth’s core material, to show. As more and more stains are accumulated in the pores of the enamel due to everyday wear and tear and our diets the teeth will develop the dull, yellowish appearance that we try so hard to avoid.
Causes of Tooth Discoloration
Now that you understand why your teeth turn yellow it is also important to understand the things that can cause your teeth to discolor. Food and drinks such as coffees, sodas, wines, fruits and vegetables can stain your teeth. Tobacco, poor dental hygiene, certain medications, and disease can also cause discoloration. Aging results in your teeth being more susceptible to wear and this is often associated with discoloration as are traumatic experiences that can disturb enamel formation.
