FAQ > bestsmile Aligner

Bleaching is only available if you opt for the aligner treatment of both jaws. You will find your free home bleaching kit in your aligner box.

The home bleaching kit contains 2 syringes of the bleaching gel Opalescence PF 10%. To whiten your teeth, simply distribute the bleaching gel evenly into your aligners.

With your home bleaching kit you can brighten up your teeth and remove discolourations

caused by, for example, alcohol, tobacco, tea, coffee or fruit juices.

Apply a thin and even layer of the bleaching gel into your aligners – from molar to molar. Then insert the aligners as usual.

If gel leaks out of an aligner, remove it with a clean cotton swab.

For best results, leave the bleaching gel on for several hours. We recommend leaving it on overnight:

Opalescence PF 10%: 8–10 hours

Opalescence PF 16%: 4–6 hours

The bleaching gel provided is sufficient for 2–3 applications per syringe.

As long as no attachments have been used, you can whiten your teeth at any time during your aligner treatment.

You may also apply the bleaching gel throughout the day. This won’t affect your whitening. The important thing is that you leave the gel on for a total of approx. 8–10 hours (Opalescence PF 10%) or 4–6 hours (Opalescence PF 16%).

Rinse your mouth twice with sufficient water and clean your aligners under lukewarm water and with a soft toothbrush. Make sure the water is not too hot, as it may cause the aligners to deform.

Important: the bleaching gel is non-edible and should be stored at room temperature. Water used to rinse off the gel residues should not be swallowed.

2–3 days after your bleaching, avoid strong pigmented foods such as red beet, curry, drinks containing colouring agents such as coffee or red wine, sugary drinks or acid fruits such as lemon or grapefruit.

If you have attachments, you can only start the bestsmile bleaching after they have been removed during the final check-up.

To apply the bleaching gel, simply use your retainer aligners.

No. The bleaching gel can only whiten natural tooth enamel.

The bestsmile bleaching is not suitable for people under the age of 18, pregnant women, women who are breastfeeding and for people with serious health problems.

Furthermore, if you have an allergy or chemical sensitivity to any of the ingredients in the Opalescence gel (potassium nitrate and fluoride), you should not whiten your teeth.
