Tooth Whitening

Tooth Whitening from Affinity DentalWe can help you achieve a perfectly white smile using our simple tooth whitening procedure.

Tooth whitening is one of the most popular treatments we offer. We can gently remove staining on or in your teeth using a painless bleaching tray technique. You control how white your teeth become by how often you use the system.

Tooth whitening (bleaching) is a cosmetic procedure for lightening the existing tooth colour. The chemical used for whitening is either hydrogen peroxide or carbamide peroxide. It can be activated using heat or heat and light combined. The chemical in the form of gel is usually applied using a specially made tray fitting your teeth.

Our dentists will usually recommend tooth whitening if your teeth are affected by:

  • general staining caused by exposure to colouring foods and drinks
  • mild tetracycline staining or flurosis (mottling)
  • age yellowing and greying.

The video below explains how the tray method of tooth whitening works.

You might not be suitable for tooth whitening if you have severe tetracycline staining, severe flurosis, plastic or peroxide allergy. It is also not recommended during pregnancy or breastfeeding to use this tooth whitening technique.

3 appointments to whiter teeth

  1. First Appointment
    During your first visit you will be told about any alternatives to bleaching and you will be warned that the necks of your teeth will not lighten as much as the rest. It will also be explained to you that you may experience some temporary sensitivity during the tooth whitening procedure. Finally we will take impressions for the trays which will be sent off to be constructed at the dental laboratory.
  2. Second Appointment
    At your second visit your dentist will fit the whitening trays and give you instruction on the correct way to use the tooth whitening system. You can then take your personalised tooth whitening kit home to carry out the procedure for a few hours each day.
  3. Third Appointment
    Your the third visit is to check the progress of your tooth whitening, follow-up to check on the results and answer any questions that you may have.
How long will the whitening effect last?

The treatment results depend on the original shade of your teeth. The effect usually lasts for one to three years but can last longer depending on the diet. Then you may need to top up. Some people find that their teeth are extra sensitive several days after the treatment has been completed but it usually wears off after some time.

Are over-the-counter whitening kits as effective?

Tooth whitening is a complex treatment procedure that should be carried out by a dentist after thorough examination and assessment of your teeth. To ensure achievement of the desired results it is important to follow your dentist’s instructions. Although the over- the-counter kits are cheaper than the whitening treatment offered by the dentist they are not as effective due to reduced concentration of hydrogen peroxide, besides, some kits contain mild acids whilst others are mildly abrasive.

Does whitening work on veneers and crowns?

Whitening only works on natural teeth and it doesn’t work on any type of false teeth including dentures, crowns and veneers. Stained veneers, crowns and dentures may need replacing so check with your dentist first.

Can whitening toothpastes replace whitening treatment?

Whitening toothpastes are no substitute for professional tooth whitening. Although effective at stain removal they do not affect the natural shade of teeth. They are helpful in maintaining the appearance of professionally whitened teeth.
