Crest 3D Whitestrips™ is not a substitute for regular dental care. Visit your dentist regularly.
Avoid eye contact. Rinse eyes thoroughly with water if gel comes in contact with them. Handle strips with dry hands.
Gel that comes into contact with the skin can cause temporary skin irritation and/or whitening. Wash hands with soap and water after use.
Avoid contact of gel with cloth, leather, or fabric.
Do not eat, smoke, sleep, or drink (with the exception of water) during use.
Tooth Sensitivity and Gum Discomfort: With all whitening products you may experience tooth sensitivity and/or gum discomfort. These effects are generally mild. These effects are temporary and not harmful. If significant tooth sensitivity or gum discomfort develops, try stopping usage for 2-3 days, then resume usage. If the problem persists discontinue usage.
If you are in need of dental work, have dental work, or have staining from medication, ask your dentist if whitening is appropriate. Crest 3D Whitestrips™ are designed to hold well to teeth. Do not use on loose teeth, restorations, or braces. Crest 3D Whitestrips™ will only whiten natural teeth. The strips will not whiten caps, crowns, veneers, fillings or dentures.
