Teeth whitening is a very common and highly effective solution for patient's wishing to restore the natural lustre and appearance of discoloured, stained or yellowed teeth.
Our dental centre offers two teeth whitening methods to select from:
External professional bleaching
This is perhaps the most successful and quickest way to whiten teeth. The process involves a dental practitioner applying a highly concentrated hydrogen peroxide gel onto the teeth's exterior. To maximise and accelerate the tooth-whitening process, a laser is typically used in combination with the gel.
Internal professional bleaching
In order to address the problem of internal staining discolouring teeth from the inside out, internal professional bleaching allows your dentist to drill a hole into your affected tooth and directly insert a bleaching agent at the root of the problem. The bleach is left inside the tooth for a short period, followed by gel removal and filling of the hole. Internal bleaching is often administered by a dental practitioner when a patient's tooth has undergone endodontic treatment (root canal therapy).
Why do teeth become discoloured?
There are several reasons why the colour of our tooth enamel may become discoloured over time. One of the main causes however, is due to what we eat and drink, combined with our oral hygiene practices.
The active element which causes discolouration are a form of pigment known as chromogens found in more intensely coloured food and beverages, from coffee and beetroot to red wine. These chromogens can stain the hard outer surface of our tooth enamel, an effect enhanced when food or drink is also sugary or acidic.
Apart from diet, smoking is another lifestyle choice which can impact the appearance of our teeth. Other factors also include certain medications, especially in those who are administered an antibiotic called tetracycline before the age of eight.
What are my options for teeth whitening?
If you are interested in undertaking a teeth whitening treatment, it is a good idea to consult with us first. Take home kits, whereby you apply teeth whitening solution at home, can show some results, but the process is a gradual one, often taking several weeks before you see any difference.
In-chair professional whitening is an intensive treatment which works to produce a change in the appearance of your teeth over the course of one or a few appointments.
