Over time, teeth can lose their brightness. Coffee, tea, dark-colored foods, tobacco, and aging can all contribute to tooth discoloration.
Why Do Teeth Become Discolored?
Some stains develop on the surface, while others occur inside the tooth. Extrinsic stains often come from foods, drinks, and tobacco. Intrinsic discoloration, however, can result from aging, trauma, medications, or developmental changes.
As we age, enamel may become thinner. Therefore, the naturally yellowish dentin underneath can become more visible.
Is Teeth Whitening Right for You?
Professional teeth whitening uses peroxide-based ingredients to lighten natural teeth. However, whitening does not work the same way for everyone.
Before treatment, your dental professional can check your teeth and gums, assess your current shade, and review your dental history. This is especially important because crowns, veneers, fillings, and bridges generally do not whiten like natural teeth.
How Can You Maintain Your Results?
Whitening is not permanent. To help maintain a brighter smile, brush with fluoride toothpaste, clean between your teeth daily, attend regular dental visits, and limit frequent exposure to staining foods and tobacco.
Some people may also experience temporary sensitivity. Therefore, discuss any existing sensitivity with your dental professional before whitening.
Ultimately, understanding the cause of discoloration can help you choose a whitening approach that fits your smile.
