Teeth whitening is a popular cosmetic procedure that helps people achieve a brighter, more confident smile. However, some people who have undergone this procedure may notice that their teeth have become yellow over time. This can be frustrating and confusing, especially for those who have invested time and money in getting their teeth whitened. In this article, we will discuss the different types of teeth discoloration and why teeth can become yellow after whitening.
Types of Teeth Discoloration
There are two types of teeth discoloration: extrinsic and intrinsic. Extrinsic discoloration occurs on the surface of the teeth and is caused by external factors such as food, drinks, and smoking. Intrinsic discoloration, on the other hand, occurs inside the tooth and is caused by factors such as aging, genetics, and certain medications.
Why Teeth Can Become Yellow After Whitening
Teeth whitening works by using a bleaching agent to remove stains and discoloration from the surface of the teeth. However, if the underlying cause of the discoloration is not addressed, the teeth may become yellow again over time. For example, if a person continues to smoke or drink coffee after getting their teeth whitened, the stains will eventually come back.
Other Causes of Yellow Teeth
In addition to discoloration, there are other factors that can cause yellow teeth. These include:- Enamel erosion: Over time, the enamel on the teeth can wear away, exposing the yellow-colored dentin underneath.- Poor oral hygiene: Not brushing and flossing regularly can lead to the buildup of plaque and tartar, which can cause yellowing.- Aging: As we age, the enamel on our teeth naturally becomes thinner, making the yellow-colored dentin more visible.
Preventing Yellow Teeth
To prevent yellow teeth, it is important to practice good oral hygiene. This includes brushing your teeth at least twice a day, flossing daily, and visiting your dentist for regular cleanings. It is also important to avoid smoking and limit your consumption of foods and drinks that can stain your teeth, such as coffee, tea, and red wine.
Treatment Options for Yellow Teeth
If you are unhappy with the color of your teeth, there are several treatment options available. These include:- Teeth whitening: This is the most common treatment for yellow teeth. It can be done in-office or at home using a bleaching agent to remove stains and discoloration.- Dental bonding: This involves applying a tooth-colored resin to the surface of the teeth to cover up stains and discoloration.- Veneers: These are thin, custom-made shells that are placed over the front of the teeth to improve their appearance.
Conclusion
Teeth whitening can be an effective way to achieve a brighter, more confident smile. However, it is important to understand the different types of teeth discoloration and why teeth can become yellow after whitening. By practicing good oral hygiene and avoiding habits that can stain your teeth, you can help prevent yellowing and maintain a beautiful smile. If you are unhappy with the color of your teeth, there are several treatment options available to help you achieve the look you want.
