Cosmetic dentistry encompasses a range of elective treatments designed to enhance the appearance of teeth. A common procedure is professional teeth whitening, a dentist-directed process that utilizes regulated whitening gels through either in-office applications or customized take-home systems. Following a whitening procedure, specific aftercare is necessary to maintain the results. Here’s more information on teeth whitening and aftercare:
What Causes Staining?
Tooth discoloration can originate from various sources, from food stains to age-related stains. Understanding these causes can help you manage and prevent future discoloration. Extrinsic stains affect the outer layer of the tooth, known as the enamel. These surface stains are often caused by lifestyle and dietary factors. Tobacco use, both smoking and chewing, is a significant cause of extrinsic staining. Some other common contributors include pigmented foods and beverages like:
- Coffee
- Tea
- Red Wine
- Dark Berries
- Soy Sauce
Intrinsic stains occur within the tooth structure, in the dentin layer beneath the enamel. This type of discoloration can result from factors like trauma to a tooth, exposure to certain medications during tooth development, or excessive fluoride use in early childhood. Intrinsic stains are located deeper within the tooth and are not addressed in the same way as surface stains.
Age-related stains are a combination of extrinsic and intrinsic factors. As a person ages, the enamel on their teeth naturally becomes thinner, allowing more of the yellowish dentin underneath to show through. At the same time, teeth accumulate more extrinsic stains over a lifetime, contributing to an overall darker appearance.
What Are Some Whitening Options?
Several methods are available for individuals interested in teeth whitening, ranging from widely available retail products to professional, dentist-supervised treatments. Over-the-counter products, such as whitening toothpastes and strips, are available at most pharmacies and retail stores. These products contain low concentrations of whitening agents and are designed to address surface stains.
Dentist take-home trays involve custom-fitted trays created from an impression of your teeth. A professional whitening gel is provided to use in the trays at home over a prescribed period. This method allows for professional-grade whitening with the convenience of at-home use.
In-office whitening is performed entirely in a dental clinic. This procedure involves the application of a high-concentration whitening gel directly to the teeth, often activated by a specialized light. It is the fastest method for achieving noticeable shade changes.
What Is Aftercare Like?
Following a professional whitening treatment, results can vary, but proper aftercare is key for sustaining your results. Professional whitening gels are formulated to act on surface and subsurface staining while maintaining enamel hardness when used as directed by a dental professional. It is common to experience temporary tooth sensitivity after a whitening procedure. Higher-concentration whitening solutions may impact the microstructures of your tooth enamel, affecting its microhardness. If treatments are excessively done, you increase your risk of more damage or demineralization occurring.
Avoid Teeth Staining Foods
Immediately after whitening, your teeth are more susceptible to absorbing stains. For this reason, it is often recommended to avoid consuming dark-colored foods and drinks for a while. Keep up on your oral hygiene and protect your initial results with lighter colored foods.
Maintain Whitening Treatments at Home
Long-term maintenance relies on good oral hygiene and periodic touch-ups. Brushing twice daily, flossing regularly, and attending routine dental cleanings help prevent new stains from forming. For those using take-home systems, your dentist can provide guidance on when and how to perform touch-up treatments to maintain your desired shade. If you experience sensitivity, using a desensitizing toothpaste can provide comfort.
