3D Crest White Strips should be left on for 30 minutes each day. It is important to make sure that the strips are firmly pressed on to the surface of the teeth to ensure that they are effective. You should not eat or drink while the strips are on your teeth, and after 30 minutes, the strips should be removed and discarded.

What happens if you leave Crest whitening strips on longer than 30 minutes?

Leaving Crest Whitening Strips on longer than the recommended 30 minutes can cause damage to the enamel of your teeth. The hydrogen peroxide in the strips can erode the enamel, leading to increased sensitivity, discoloration, and even cavities. Additionally, the strips may not be as effective if left on for longer periods of time. It is recommended to follow the instructions on the package and not leave the strips on for more than the recommended time.

What happens if you leave Crest 3D whitening strips on too long?

Leaving Crest 3D Whitening Strips on for too long can cause tooth sensitivity and irritation. The strips contain hydrogen peroxide, which can weaken and damage your teeth if left on for too long. It is recommended to only wear the strips for the recommended amount of time as stated on the package – typically 20-30 minutes. If you experience any discomfort or sensitivity while wearing the strips, remove them immediately and consult your dentist.
