Product Description


Crest Whitestrips Supreme: Our Bestselling Teeth Whitening Kit!


Key Facts about Crest Whitestrips Supreme teeth whitening strips

Crest Whitestrips are the world's most popular teeth whitening product: available in a variety of different strengths the Supreme version are the strongest and usually only available directly from your dentist - you won't find them in the shops!

Crest Whitestrips use a unique '3D Advance' strip design: the premium whitening gel is embedded onto an ultra-thin strip of clear plastic that is stuck to the front surface of your teeth. The new formula means the strips stick better than ever and create a water-tight seal on your teeth, simply wrap the edges of the strip around your teeth and apply light finger pressure to the front of the strip to push into place.

Strips are worn for only 30 minutes, during this time you can talk and even drink water normally: perfect if you have a busy life and don't want your teeth whitening to get in the way.

Results can be seen from the first use, with full results visible after only 1-2 weeks. Any left-over strips can then be used for top-ups every 6-12 months to keep your teeth beautifully white.

The larger strip goes onto the upper teeth, peel of the strip from the backing.

Step 2: Apply the strips to your teeth

Place the strip carefully onto the front of your teeth with the top of the strip resting just below the gumline.

Use light finger pressure to push the strip tightly onto your teeth, getting into the gaps between the teeth sligthly.

Wrap the bottom of the strip around your teeth so it rests securely on the back of the teeth.

Step 3: Wear for 30 minutes!

Whilst wearing the strips you can talk and even drink water however it is not advisable to smoke or eat until after whitening.

Once finished, peel away the strip and rinse with water.

Whitening Safety

Does teeth whitening damage the enamel or gums?

No! All the teeth whitening products you find on are manufactured by leading accredited teeth whitening brands and are 100% enamel-safe and meet all American safety regulations. Our products are pH-neutral: they will not dissolve or damage the enamel of your teeth and although teeth whitening gel can irritate gums if it spills onto them any irritation is temporary and no permanent side-effects have ever been documented in the dental research.

Teeth whitening gel works by soaking into the teeth through the micro-holes in the surface where it acts on large staining molecules, bleaching them into white molecules. This makes the tooth appear lighter and brighter. The gel does not effect the hard minerals in the tooth.


Whitening your teeth safely: What you need to know

Teeth whitening using peroxide-based teeth whitening gel is safe and effective when all instructions are followed carefully.

Teeth whitening gel has 2 main side-effects: sensitivity and gum irritation. Sensitviity affects over 80% of people who whiten their teeth, it is usually felt after 1 or 2 days of teeth whitening and is similar to biting into ice cream. The sensation only lasts a fraction of a second and can occur several times a day spontaneously or when eating/drinking hot and cold things. Although this can feel alarming, it is perfectly normal and occurs with professional and home treatments equally. Sensitivity usually decreases after 3 days or within 2 days of stopping whitening and is not permanent.

Gum irritation is more common in home teeth whitening kits as the trays are usually not as close fitting as professionally made ones. If peroxide gel contacts the gums it can cause a localised chemical burn and may temporarily turn the gums white. Gum irritation can be sore and if severe may cause sloughing of the gums - the effects are however not permanent and the gums recover back to their original form quickly.

Who should not whiten their teeth?

Teeth whitening is not recommended in the following individuals;

  • Pregnant and nursing women (due to lack of testing to ensure complete safety)
  • Those with severe gum disease
  • Those recoving from gum/oral surgery

Teeth whitening is also not recommended if you have crowns (caps), veneers, bridges or fillings visible at the front of your mouth as the whitening gel will bleach the surrounding natural teeth but cannot whiten artificial materials - this may lead to dental work becoming more obvious as the colour is no longer matched to your natural teeth.


Tips and tricks for avoiding sensitive teeth

Sensitivity can be uncomfortable and may stop you whitening as often as you wish, meaning results can take longer to achieve.

Sensitivity can be avoided by using desensitising gels - these contain the same ingredient as found in sensodyne toothpaste but in much more concentrated form and act to calm the nerves of the teeth. Simply apply the gel to the trays and wear over the teeth for 20-30 minutes either before or after teeth whitening as needed.

Tips and tricks for avoiding sore gums

Sore gums can be caused by gel leaking out of the trays onto the sensitive gum around the teeth. The first thing to try is trimming your trays down along the gum line, this means only the teeth are covered by the trays so any excess that leaks out can be simply wiped away with a cotton bud or your finger!

Another tip is to be careful not to apply too much gel to the trays - you only need a small dot of gel for each tooth (approximately 0.25ml per tray). The gel will diffuse into the teeth so don't worry about covering the entire surface.
