Welcome back to our final whitening blog. As promised in our last blog, we will go though the different forms of whitening.


To whiten our teeth we need to penetrate then enamel layer. This is done by using a solution called carbamide peroxide. In house whitening uses higher levels of carbamide peroxide (“whitening gel”) than take home trays allowing for faster results in terms of more shades in a shorter period of time.

However the process usually results in a higher level of tooth sensitivity,


Take home trays are simply personalised made trays that fit perfectly for your teeth.

These trays are made by taking impression of both your upper and lower and take no longer than a week to be made in our lab.

Using this system of whitening requires less whitening gel than in house whitening but as a result there is far less sensitivity.

The advantage of take home trays is that you can whiten your teeth anytime you like and to the shade you want your teeth.

The trays are yours to keep, when you require more whitening gel you can just make a quick stop at you dentist.

Keep in mind that whitening results will very from person to person.


The best and cheapest way to have a bright white smile is to maintain good oral hygiene.

  • Brush twice a day with a soft bristle toothbrush.
  • Floss daily
  • Drink water continually throughout the day
  • Consume a healthy diet
  • Visit your dentist and hygienist regularly.

 Keep in mind that whitening results will vary from person to person as each individual is subject to different conditions that will affect their whitening results.
