When will I see results?
You can expect to see visibly whiter teeth in just one day when used as directed.
How long will the whitening effect last?
Because tooth staining is mostly caused by the things we eat, drink (tea, coffee, wine), the duration can vary greatly. Using Colgate whitening toothpaste and mouthwash can help prevent new stains from accumulating and can help prolong the whitening effect.
Does the Express Pen cause sensitivity?
This product is designed for no tooth sensitivity, during and after the whitening process. The product has been developed specifically to provide precise application to teeth, so you can avoid applying to the gums. To minimize irritation, avoid contact with gums and soft tissue. Avoid direct contact of the product with the gums and/or salivary flow. If irritation of the gums or mouth occurs, discontinue use and consult a dentist. Some people may experience tooth sensitivity or gum discomfort when using whitening products. This discomfort is temporary and not harmful. If you experience more than mild tooth sensitivity, stop use and consult your dentist.
How should I clean the pen brush?
You do not need to clean the pen, as you can simply immerse it back into the bottle. But if you would like to clean it, simply wipe the bristles with a tissue. Do not use water.
