Yes. The Perfect Smile Whitening Kit is safe for people with braces, bridges, implants, crowns and fillings. However, there are several factors to consider.
Unfortunately, teeth whitening only affects the color of your natural tooth structure. According to the American Dental Association (ADA), whitening treatments will not change the color of bridges, implants, crowns and fillings, as they are generally made of porcelain, or other non-porous substances like acrylic, and impossible to whiten with peroxide. Tooth enamel, by contrast, is porous and peroxide is able to penetrate its surface, enabling it to break apart staining agents inside the tooth.
Due to the unnatural composition of porcelain, dental practitioners usually advise their patients to whiten their teeth before any new dental work is carried out. The dentist can then ensure the bridge, crown, implant or filling matches the whitened teeth.
If you wear traditional metal braces, it is strongly recommended that you wait for them to be removed before whitening your teeth. The metallic brackets are obstructive and can lead to uneven results. However, lingual braces and clear removable aligners will not affect the whitening process.
