Professional teeth whitening brings back the beauty of your smile while supporting comfort and safety

As we age, teeth become stained. It’s a simple fact of life, although certain dietary and oral hygiene habits can cause more severe yellowing. Consumption of dark beverages like coffee, tea, and soda can lead to stains, as well as dark foods like berries and tomatoes. If you want to brighten dull, yellow teeth, Shine Dental has options that will enhance your enamel and boost your confidence!

We offer both in-office chairside whitening and take-home whitening for our patients, providing you with flexibility

Attractive smiles are “in harmony” with each other. There is symmetry and balance in everything from the size and shape of the teeth to how they are positioned or spaced to neighboring teeth or in relation to the opposing teeth when a patient closes his or her mouth. Professional teeth whitening supports a beautifully balanced appearance by addressing stains and other forms of discoloration, including white spots. 

Additionally, because Dr. Zhao oversees every aspect of treatment, you can assure that the results from teeth whitening at the Harmony Smile Dental office in Sunnyvale, California, look naturally beautiful. Since we customize the whitening method and concentration of the gel to your facial characteristics and goals for improvement, the level of whitening is well-suited to your unique features and needs. Furthermore, this approach supports utmost comfort. Modifications can be made to minimize the risk of sensitivity; for instance, Dr. Zhao may adjust the time the whitening gel is in contact with the teeth, or he may use a less concentrated gel with active, peroxide-based whitening ingredients. 

Also, the product is applied evenly and directly by Dr. Zhao (in the case of in-office chairside whitening). Or, the product is applied evenly by using whitening trays or custom-made appliances to fit the patient’s mouths perfectly. Over-the-counter whitening trays are designed to “fit all mouths.” So, they tend to slip around. This situation can lead to trays that irritate the tissues inside of the mouth and can also prevent the gel in the trays from being delivered uniformly to the teeth. The gel itself may leak, which results in further irritation caused by the whitening product itself. 

By partnering with the professionals at Harmony Smile Dental, you avoid concerns associated with effective and attractive results, safety, comfort, and hypersensitivity. Following an evaluation at our practice, Dr. Zhao may recommend either office whitening or whitening from the comfort and convenience of home. As noted above, the former option is that Dr. Zhao applies a whitening gel product that is prescribed to your unique specifications to the teeth. The rest of your mouth outside the teeth is protected with a covering. That way, even results are supported as well as a comfortable and safe experience. In-office professional teeth whitening is generally activated by a light-based device, such as a laser. This form of activation produces super-fast and often dramatic improvements. Our patients can get teeth lightened by several shades in around one hour and within a single appointment. 

Take home whitening, Dr. Zhao and his team will use impressions or models of your mouth to create custom whitening trays. We’ll show you how to fill these trays with bleaching gel. The trays comfortably and precisely slip over your teeth. When worn as directed, these appliances transfer the whitening gel to the teeth. You continue to wear the trays as instructed until the desired level of whitening is achieved. Sometimes, patients with healthy mouths may jumpstart whitening with an in-office treatment and sustain the beautiful results with home whitening trays.
