Once you get the shade you desire, use the strips once a month as a refresher to maintain them.

Strips are recommended to be used after the age of 20 years old when the enamel is strong enough to support a whitening substance. Your diet needs also to contain as few sugary foods or fizzy drinks as possible and coffee or smoking should be drastically lowered if you want a good result.

The best way to use them is either during the day or before bedtime. If you use them before breakfast your teeth may get stained as the enamel has micro porosities after using whitening strips and also sensitivity may occur.

Expert Answer

Teeth whitening strips are generally very safe for patients, although you won't get the same results as you would from a professional whitening treatment. Make sure to brush your teeth first so the hydrogen peroxide in the strips can penetrate the enamel better, and avoid eating anything for an hour after the treatment for the best effects. However, avoid using whitening strips if you have braces or restorative work such as fillings, veneers, crowns, or dentures.
