Teeth Whitening

Your smile is important – it’s one of the first things you notice when you meet someone. A whiter brighter smile could help you feel better about yourself and leave a memorable impression.

Teeth Stains

Your lifestyle and the ageing process can stain and darken your teeth, such as drinking coffee, tea, coke and red wine or smoking.

Teeth whitening can help get your smile looking its best. You should look for a whitening procedure that is:

    • Fast and convenient
    • Long lasting
    • Proven to be safe and effective

Rawson Dental Teeth Whitening Procedures

At Rawson Dental, we offer 2  different types of whitening procedures.

In Surgery Teeth Whitening

In Surgery Whitening takes just over an hour where you relax in the chair and Dr Le will do the lightening process for you.

This includes a take home kit where you can “top up” your shade before a big event like a wedding/party, when or if your teeth start to restain.

Take Home Teeth Whitening

A custom take home kit is created for you. We will also show you how to apply the whitening gel. This process takes 2 to 4 weeks.

How does Teeth Whitening work?

Teeth Whitening is a procedure designed to lighten the colour of your teeth using hydrogen peroxide (or carbamide peroxide). The teeth whitener comes in a gel form.

Who is suitable for Teeth Whitening?

With most patients, a significant lightening is achieved, however results may vary in different people. Factors affecting the success include:

  • The base colour of the tooth – yellow-hued teeth generally respond the best, while grey, brown and orange teeth are more difficult
  • The reason for discolouration
  • The degree to which the tooth is restored

Tetracycline stains usually respond to some degree although optimum results are rarely achieved and treatment may take significantly longer.

Certain medical conditions can preclude the use of Teeth Whitening:

    • Patients who are pregnant or lactating
    • Have sensitive teeth
    • Are under the age of 16

What are the potential problems?

Tooth and Gum Sensitivity

Teeth and gums may become sensitive following Teeth Whitening. This can be helped by leaving the tray out for a night or reducing the number of hours of wear. Placing tooth mousse into trays and wearing them for a few hours after each treatment will help. Symptoms will usually subside within 1-3 days of cessation of treatment. Ensuring the trays are not overfilled with Teeth Whitening gel will reduce the likelihood of gum sensitivity.

Uneven Colour

Tooth colour may be uneven across the surface of the tooth, especially if the tooth was of uneven colour prior to Teeth Whitening. The cervical 1/3 of the tooth is often slightly darker than the incisal 2/3. White spots or lines can be seen on the teeth which are due to dehydration of the tooth substance and will usually fade within 1-2 weeks of the end of treatment. In teeth with cracks, the cracks may be seen to lighten more than the surrounding tooth.

Dark Fillings and Crowns

As the tooth coloured fillings and crowns will not lighten with Teeth Whitening they may need replacing following treatment, although this will need to be left for at least 2 weeks until the tooth colour has stabilised.

Top Ups

Over time the teeth will darken again due to the stains in foods and drinks we consume and you may need top ups. This is done by wearing the trays for a few nights. The period between top ups will vary between patients and can vary from once every few months to no need for further top ups. This will usually be related to the number of staining agents the teeth are exposed to and the level of lightness the patient is trying to maintain.
