How the strips work

  1. Apply

    Press one strip onto your upper teeth and one onto your lower teeth. Dry teeth hold the strips best.

  2. Wait

    Leave them on for the time printed on the box. You can talk and drink water in the meantime.

  3. Peel off

    Remove the strips and carry on with your day. One treatment a day, for as many days as the box holds.

Questions people ask

Are these the real Crest strips?

Yes. Crest 3D Whitestrips are made by Procter & Gamble for the American market. We sell only original Crest products, no copies.

How many treatments are in a box?

It depends on the kit, from 5 to 20 treatments. The number is on each product page; one treatment is one upper and one lower strip.

Will the strips hurt sensitive teeth?

Some people feel a passing sensitivity during the course. The Sensitive & Gentle kits are made for exactly that; if a day is uncomfortable, skip it and carry on the next.

How long does delivery take?

Every order is sent tracked. Delivery times and costs are shown at checkout before you pay.

Can I return an order?

Yes. Unopened boxes can be returned; the returns page explains how.
