Get up to 16 shades whiter teeth

With Dr Collins 16% you can whiten from C4 up to B1, a total of 16 shades. Just stop when you've reached the shade you want!

*Please note: severely discoloured teeth may take longer than 2 weeks to whiten and you may need additional gel to reach your required shade


16% Carbamide Peroxide: Standard Stength

With 16% tooth whitening gel you can still get maximum whitening results but it will take longer to achieve them - the benefit is that you get less sensitivity and risk of gum irritation. Research is also showing that whitening using a low strength over a longer period of time leads to longer-lasting results!

We recommend 16% gel if you have used 16% before or would like a more gentle whitening gel that is more comfortable to use and does not need to be worn overnight.

How to use Dr Collins: Step by Step

Please note, complete detailed instructions are included with each order

Step 1: Make your teeth whitening trays

Boil water in a kettle and pour into a deep cup. Submerge the trays in the water for 5-10 seconds until limp.

Place over teeth, sucking air from the tray and applying pressure with your fingers along the front of the teeth.

Remove and leave in cold water for 10 seconds. Trim tray tab.

Step 2: Apply the teeth whitening gel

Apply a dot of teeth whitening gel to the front surface of each tooth indentation in the tray.

You do not need to apply lots, approximately 0.25ml will be sufficient for each tray. Overloading can cause gum irritation.

Step 3: Wear the trays for 1-4 Hours

Place the trays over your teeth and apply light finger pressure to spread gel slightly over tooth surface.

Any excess gel can be wiped away.

Wear for 1-4 hours for up to 3 weeks (or stop when desired shade reached).

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.
