Comprehensive Teeth Whitening Care

A Smile So Bright It Lights Up The Room

Teeth whitening has come a long way since the days of at-home bleaching treatments. Designed to restore whiteness and brilliance to your smile, modern whitening treatments have immediate and noticeable results.

At-home teeth whitening kits may seem like a quick and affordable whitening solution, however, if done correctly can lead to damage to your teeth and enamel. Thus whitening procedures should be conducted by professionals with the tools, equipment and knowledge to successfully and safely whiten your teeth.

Our in-chair teeth whitening services are performed by our team of dental experts, who will explain your procedure and ensure you have all the necessary post-procedure care instructions.

Over With Discoloured Teeth?

There are many factors that can cause tooth discolouration. The inherent colour or shade of your teeth is dependent upon the natural pigment molecules within each tooth. 

After you get your ‘adult teeth’, external stains, such as tea and coffee, absorb into the tooth structure and become intrinsic stains of the tooth, which add to the colour (or darkness).

Any bleaching or teeth whitening product must be able to penetrate these stains, as well as break down the large stain-producing molecules.

Teeth Whitening FAQs

We have answered some of the most frequently asked questions below. Have we missed something? Get in touch and our Sunshine Coast friendly staff will be happy to assist.

All teeth whitening processes in today’s market rely on an active ingredient of hydrogen peroxide. 

A breakdown of hydrogen peroxide results in the release of water, hydrogen ions and bleaching factors (molecular oxygen, oxygen ions and free radicals).

Therefore, predictable and effective teeth whitening is dependent upon the ability of bleaching factors to penetrate deeply into the micro structure of teeth.

Dentists commonly find that a single visit in-chair and power bleaching of ALL TYPES has a high incidence of unpredictability. 

This is because of the inability of the bleaching factors to penetrate into the deeper parts of the tooth.

All in-chair treatment systems will have unpredictable results depending on the permeability of a patient’s tooth structure.

Another factor of teeth bleaching is the accuracy of the tray fit. Poorly fitting trays will result in mediocre results. Both saliva and the fluid that exudes from between your gums and teeth (crevicular fluid) contain peroxidase enzymes that naturally destroy the peroxide on contact.

The microstructure of younger teeth is much more permeable to bleaching factors than that of older teeth. So, generally speaking, younger teeth can get very white very rapidly.

Whitening is probably most effective at about age 14. Older teeth can still be whitened considerably but more attention to technique, and often more time, is required to produce the desired result.

The main bleaching components are hydrogen peroxide and carbamide peroxide. Carbamide peroxide breaks down into hydrogen peroxide and urea. About one third of carbamide peroxide is released as hydrogen peroxide.

Hyrdogen peroxide is found in all body cells as an endogenous metabolite (meaning that it is produced naturally by the body itself). The adult human body produces about 650mg of hydrogen peroxide per day.

Using 16% carbamide peroxide in bleaching trays will result in you placing about 6.5mg of peroxide in a set of upper and lower trays. This means that, during cellular metabolism, our bodies produce about 100 times more peroxides per day than are placed in standard bleaching trays.

Saliva can counter teeth whitening as it contains catalase and peroxidases that rapidly break down any hydrogen peroxide released in the mouth during bleaching. Salivary and sulcular fluid peroxidases are capable of destroying 29mg of peroxide every minute.


There are two commonly reported side effects of teeth whitening treatments: Sensitive teeth and gum irritation.

Tooth Sensitivity: Typically any sensitivity will be mild and last only a day or two after completion of whitening. During Kor whitening, we place a great emphasis on reducing tooth sensitivity. It is important to ensure that your teeth are not excessively sensitive to cold drinks or foods prior to beginning whitening.

Desensitisers will also be used throughout the whitening process to mitigate any sensitivity. As hard as we may try, approximately one in 100 people will be unable to whiten their teeth because of severe sensitivity.

Gum irritation: This is uncommon during at-home procedures. If it does occur, it is usually of minor discomfort and goes away after a night off from bleaching.

Many people are unhappy with the color of their teeth, and there are a number of factors that can contribute to dental discoloration.

Smoking is a major culprit, as the tar and nicotine in cigarettes can stain teeth over time.

Coffee and tea are also well-known for causing tooth discoloration, as the dark pigments in these beverages can stick to the enamel.

Red wine is another common cause of stained teeth, as the deep red colour can seep into the porous enamel.

Certain medications, such as antibiotics, can also cause teeth to become discoloured.

 If you have any of these habits or factors in your life, teeth whitening may be a good option for you.




If your teeth are stained or discoloured, you may be considering teeth whitening. However, if the stains are deep within the enamel, other treatments may be more effective. Veneers are thin pieces of porcelain that are custom-made to fit over your natural teeth. Dental implants are artificial replacement teeth that are surgically implanted into your jawbone. These options can all help to improve the look of your smile and give you the confidence you deserve.  Contact the team today to talk about which option is right for you.
