While a bright, white smile is a sign of health and youth, teeth naturally change color for various reasons, making them appear dull or yellow. Fortunately, teeth whitening is an effective and popular way to boost their brightness and confidence. Some stains are only on the surface, while others develop within the tooth structure itself. Here is what you need to know about why the color of your teeth changes and how professional teeth whitening can help restore the brightness of your smile.
A tooth has multiple layers that determine its shade. The enamel is the hard, protective outer shell. This layer is translucent and can vary in thickness depending on the individual's genetics. Beneath the enamel lies the dentin, a dense tissue that possesses a naturally yellowish tint. When the enamel remains thick and smooth, the teeth appear whiter. However, when the enamel thins or develops stains, the yellow dentin becomes more visible to the naked eye. This shift can leave a person with an older-looking smile, even with consistent oral hygiene habits.
Two distinct types of stains affect the look of a smile: extrinsic and intrinsic. Extrinsic stains sit on the surface of the enamel and usually result from food, drink, or tobacco use. Meanwhile, intrinsic stains develop inside the tooth, frequently due to trauma or certain medications. As a result, these two types of discoloration require different approaches by a dental professional.
Several daily habits and biological changes lead to a darker smile over time. While some causes are preventable, others are a common part of the human experience. Awareness of the following factors can help patients make better choices for their long-term dental health.
Our team will work with each patient to identify the specific causes of their issues and create a customized treatment plan. By addressing the root problem, the results of the treatment last much longer.
Professional teeth whitening methods are safe and effective when performed under the supervision of a dental professional. Professional-grade bleaching gels contain high concentrations of hydrogen peroxide, a powerful bleaching agent. When applied to the teeth, the oxygen molecules from the peroxide infiltrate the porous enamel. These molecules break the chemical bonds that hold the stains together. As the stains dissipate, the teeth appear several shades lighter in a short amount of time.
Professional teeth whitening is more efficient than over-the-counter options. Over-the-counter whitening strips and pastes usually only target the surface and do not reach the deep-set stains within the enamel. In contrast, an in-office treatment at our office or take-home whitening trays provides a more uniform and dramatic change. Our team ensures the safety of the gums and soft tissues throughout the treatment process, which minimizes the risk of tooth sensitivity or irritation.
After the patient achieves a brighter smile, they will need to take proactive steps to protect the long-term benefits of their investment. The longevity of the treatment depends on how well a person manages their diet and oral care routine. Fortunately, making small changes to daily life prevents new stains from forming and keeps the smile looking refreshed for months or even years. Some helpful habits may include:
Proper care and maintenance ensure that the results remain visible and beautiful for the long term. Additionally, patients who follow these guidelines to maintain their smile typically need fewer touch-up appointments over time.
