What is Teeth Whitening?
Teeth whitening, or bleaching, refers to any process that makes your teeth appear whiter. It’s a non-invasive procedure designed to brighten teeth that have become stained, discolored, or yellowed over time. Since its introduction in the 1980s, teeth whitening has become incredibly popular. In fact, when the American Academy of Cosmetic Dentistry asked people what they’d most like to improve about their smile, the top answer was “whiter and brighter teeth.”
Why Do Teeth Become Discolored?
The color of your teeth depends on how light reflects off the enamel, the outer layer of the tooth. Teeth can become discolored for many reasons. External stains, like those caused by certain foods, drinks, and tobacco, can dull your smile. Internal discoloration, on the other hand, can be due to genetics, medications, tooth decay, restorations, or trauma. As we age, teeth naturally appear more yellow because the enamel thins, revealing the darker dentin underneath.
Why Choose Professional Teeth Whitening?
While over-the-counter whitening products have grown in popularity, they come with certain risks and limitations. If used incorrectly, some products can damage your teeth or gums, and they often don’t deliver the promised results. Whitening systems contain bleaching agents like hydrogen peroxide or carbamide peroxide, but their effectiveness depends on how they’re used and the health of your teeth.
Professional teeth whitening, performed by a dentist, is the safest and most effective option. Dentists carefully assess the condition of your teeth and gums to ensure the procedure is suitable for you. Whitening may not be recommended if you have sensitive teeth, exposed roots, cavities, cracked teeth, or extensive dental work like crowns or bridges, as these restorations won’t change color. Additionally, people with yellow-toned teeth tend to see the best results, while those with brown or grayish stains may need longer treatments or alternative options.
In-Office Teeth Whitening
For fast and dramatic results, an in-office whitening procedure is the best choice. In as little as one hour, your teeth can be lightened by several shades with prescription-strength whitening agents. During the procedure, your dentist will carefully protect your gums and any sensitive areas to ensure a safe and comfortable experience.
Take-Home Whitening Kits
A take-home whitening system provided by your dentist is another great option. Custom trays, fitted specifically to your teeth, ensure that the bleaching agent stays in contact with your teeth while protecting the rest of your mouth. Although the results take longer compared to an in-office treatment, take-home kits can be used on their own or as a follow-up to maintain the results of an in-office procedure.
