Our clinic uses the BEYOND Cold Light Whitening technology from the United States to provide patients with professional teeth whitening treatment.

The principle works by allowing the whitening agent to penetrate the tooth structure through cold light, achieving a whitening effect.

The BEYOND cold light whitening gel is internationally recognized as a highly effective and safe dental bleaching agent. It not only removes surface stains on the teeth but also penetrates deep into the tooth to brighten its color.

About teeth whitening results

The results of teeth whitening vary from person to person, and it is difficult to guarantee that every patient will achieve the expected outcome or see improvement from their current condition. After whitening treatment, the teeth will appear a more natural shade of white — they will not become as white as porcelain, paper, or a doctor’s white coat. In most cases, according to the tooth shade guide (compared under natural light), the color of the teeth may improve by 2 to 4 shades (for reference only).

Can all types of teeth be whitened?

Teeth whitening is not a universal solution. For teeth with severe tetracycline or fluoride staining, the effectiveness of current whitening treatments is limited. Generally, yellow or yellow-brown teeth respond better to whitening than gray or gray-brown (gray-blue) teeth.

Whitening has little to no effect on synthetic dental materials such as fillings, dentures, veneers, porcelain crowns, or bridges, and it cannot change the shade of these coverings. As a result, after whitening treatment, the color of your teeth may appear uneven, with existing restorations standing out.

If a tooth has undergone root canal treatment, depending on the condition, we may recommend placing the whitening agent inside the tooth (in the space where the nerve used to be) to achieve whitening from the inside out. However, the feasibility of this treatment will be determined by the attending dentist.

About at-home whitening results

At-home whitening involves placing a bleaching gel into a custom-made tray and applying it at home under the dentist’s instructions. If you choose at-home whitening, results usually appear within about a week. However, if the effect is not satisfactory, the whitening period may need to be extended — please consult your dentist for further guidance.

Does whitening treatment have side effects?

The most common side effect of whitening is tooth sensitivity. During or after treatment, some patients may experience sensitivity to hot or cold foods. Other possible symptoms include sensitivity to biting pressure, gum warmth or tingling, mucosal irritation, and toothache. These symptoms usually resolve within 4–7 days.

If such symptoms occur, it is recommended to reduce the intake of acidic foods and drinks (such as citrus fruits, sodas, vinegar and vinegar-based foods, vitamin C, sour plums, sports drinks, yogurt, etc.) to avoid acid erosion. If the condition persists, desensitizing toothpaste can be applied to the sensitive areas to relieve symptoms. If there is no improvement after using desensitizing toothpaste, please contact your dentist. With your dentist’s approval, pain relievers may also be taken to ease discomfort. Typically, tooth sensitivity subsides within 6–24 hours after treatment.

How long can the whitening results last?

The duration of whitening results depends on the condition of your teeth, as well as your dietary and oral hygiene habits. During the whitening process and within 24 hours after treatment, you should reduce the intake of dark-colored foods and beverages, such as coffee, tea, cola, oolong tea, red wine, cigarettes, cigars, curry, berries, chocolate, tomato sauce, soy sauce, and other sauces. It is also recommended that patients return for regular dental check-ups every 3 to 6 months.
