Discoloration
Over time, your teeth might become slightly (or perhaps more than slightly) discolored. They are no longer as bright and white as they once were, and you are starting to notice a difference in the way that your smile makes you feel. This is perfectly normal! Even with proper oral hygiene, tooth discoloration can occur. Our teeth are directly affected by everything that we eat and drink as well as any illnesses that we might be struggling with, so it makes sense that they would eventually begin to show that impact in a visible way.
Some of the worst offenders when it comes to tooth discoloration are dark colored beverages. Coffee, for example, is a huge culprit when it comes to the yellowing of teeth. This is especially true if you tend to sip your coffee rather than drink it straight down, as the liquid has more time to stain your teeth. Tea can have the same effect, as can soda. The best thing you can do if you want bright white teeth is to take a look at what you are putting into your body, and avoiding things that are known to cause discoloration.
Medication and Smoking
Two other big culprits when it comes to the yellowing of teeth are medication and smoking. Certain medications can make it harder for your mouth to produce the amount of saliva that it needs to function well, which can, in turn, make it easier for food and beverages to linger in your mouth and discolor your teeth. Smoking is a huge reason that many people have yellow or otherwise discolored teeth.
The reason we bring up how your teeth become discolored is that even after having your teeth whitened, if you continue with the same habits they will eventually become discolored again. It is a good idea to take a look at your food and beverage intake to see how you can promote bright white teeth.
