Discolored teeth can cost you the confidence to talk or even smile in front of your friends and peers. Tooth discoloration is caused by several factors, ranging from poor oral hygiene and lifestyle to genetics and underlying health conditions.
With the right cosmetic treatments, your dentist may be able to help you correct tooth discoloration and renew the whiteness of your smile. However, the effectiveness of these treatments will depend on whether the stains are extrinsic or intrinsic. Read on to find out more.
Understanding Tooth Discoloration
Tooth discoloration can generally be classified as extrinsic or intrinsic. Extrinsic dental stains are usually brown or yellow. This discoloration originates on the tooth surface and is often a result of external factors such as lifestyle and eating habits. For instance, you can develop yellow teeth if you smoke cigarettes, chew tobacco, or frequently drink dark beverages like soda, red wine, coffee, and tea. Treatment options for extrinsic dental stains include professional teeth whitening services, dental bonding, and porcelain veneers.
On the other hand, intrinsic dental stains originate from within the teeth and vary from yellowish or brownish discoloration to gray or white stains. Common causes of intrinsic stains are injuries, excessive use of certain antibiotics, too much fluoride, and genetics. Treatment options for intrinsic dental stains are dental bonding, porcelain veneers, and porcelain dental crowns. Professional teeth whitening is not effective at correcting intrinsic dental stains.
Yellow Stains and Possible SolutionsIf you have yellow stains or discoloration on your teeth, several factors could be to blame. In order to choose the best treatment to revitalize your smile, it’s best to understand the root cause of the problem. Besides genetics, foods, drinks, and lifestyle habits, other causes of yellow tooth discoloration include:
- Exposed dentin – As your enamel wears out and becomes thin, it reveals the dentin beneath. This deep yellow to brownish material gives your teeth a yellow tint when exposed by weakened enamel.
- Tooth Grinding – Unconscious teeth grinding, especially while asleep, is another possible cause of yellow teeth. Commonly known as bruxism, this condition can weaken your enamel and cause yellow discoloration. It can also make your teeth more susceptible to damage and decay.
- Fluorosis – Excessive fluoride exposure can cause yellow spots on the surface of the teeth called fluorosis. Common sources of fluoride are fluoridated water, prescription fluoride tablets, and fluoride toothpaste. It’s a good idea to consult with your dentist to ensure your getting the ideal amount of fluoride.
