Designed for teeth with varying levels of stains and discoloration, Crest 3D White Professional Effects helps get rid of long-time stains and let your teeth stay stainless for up to 12 months.
Suitable for use at any time of the day, these white strips need only be applied for 30 minutes to deliver noticeable results after the very first application.
The strips are super effective and show results on teeth discolored by long-time stains. The box comes with 44 strips with 20 moderate intensity and 2 high intensity treatments. The box instructs you to leave the moderate intensity strips on for 30 mins and the high intensity ones for one hour to do their work.
The one-hour-long strips show noticeable change and whiteness in teeth right after taking them off.
The 40 strips lasting 20 days start showing results after only 3 days of daily use.
It provides enamel-safe whitening and works faster than most other competitive strips. The strips are small in size, flexible to touch, and easy to put on without too much inconvenience.
The no-slip grip feature lets you go about your day as the strips do their work. They have excellent adherence that is safe to apply directly to the tooth’s surface and peel away just as easily once the 30 minutes are over.
Their flexible construction makes it easy for the strips to mold to the teeth without leaving any spots uncovered. That said, it is best to ensure that your teeth are clean before you apply the strips so that food or other substances don’t prevent the strips from contacting firmly with the tooth’s surface.
Both manufacturers and users agree that these strips are safe for daily use. Customers have used them on sensitive teeth and achieved good results without any problems.
But manufacturers do indicate that they are not meant for use on missing teeth as the chemical whiteners included aren’t intended for prolonged contact with gums. Such contact may irritate or harm the exposed areas.
Unless allergic to any of the listed ingredients the strips are considered safe for use.
Value for money
The box contains 44 strips, good for 20 uses with the effects lasting up to 12 months. They also have an excellent shelf life so if you don’t use all the strips in one go, they will last you well for subsequent treatments later on without losing potency.
Overall, excellent value for the money paid for this product.
