Frequently Asked Questions

1 Is whitening for everyone?
Teeth whitening is a safe and comfortable way to achieve a bright white smile. The results and the duration of the treatment may vary depending on the initial tone of your teeth and the desired result. Crowns, bridges, reconstructions and veneers are never whitened. We recommend visiting your dentist for a prior consultation that can help you choose the professional option that best suits your needs.

2 How long does teeth whitening last?
The results of a professional whitening are very stable, your splendid and bright smile remaining long after the treatment. However, there are some factors that influence the duration of treatment. Factors such as genetics, diet, age, some medications (such as tetracycline), and certain habits (such as smoking) can affect how long your whitening results last. Fortunately, there are quick and easy touch-up treatments that will help you keep your smile white and bright for much longer.

3 Does whitening cause tooth sensitivity?
Tooth sensitivity is a relatively common side effect of whitening. If sensitivity occurs, it will be temporary and will disappear after whitening is complete. However, most Opalescence PF products include desensitizing agents such as potassium nitrate and fluoride, these agents have proven to be effective in reducing or eliminating tooth sensitivity, producing greater patient comfort.

Opalescence has been specially formulated and is therefore available in different strengths and flavors. This means that you can whiten your teeth by choosing the option that best suits your lifestyle and habits. You can whiten your teeth c with a personalized tray (Opalescence PF, home use), with a pre-filled tray (Opalescence GO, home treatment) or with a medical treatment (Opalescence Boost, exclusive use in clinic). The Opalescence family of products offers you the professional whitening option you need.

6 I have heard of some whitening treatments that require a light. Are these lights really effective?
Many treatments use a light or laser during the whitening process. You have probably seen advertisements for this type of tooth whitener or maybe you have even seen kiosks in shopping malls where a light is used to whiten teeth. Are these lights and lasers really effective?
The answer is no. Current studies show that hydrogen peroxide, the whitening agent contained in Opalescence Boost, used alone (without any additional light) is effective for teeth whitening, meaning activation by light does not add any additional benefits.
