A plain look at teeth whitening in Geelong. How dentist supervised whitening works, what changes the result and why a check up comes first.
Teeth whitening in Geelong is a dental treatment that uses a peroxide based gel to lighten the natural colour of your teeth. It works on the enamel and the layer underneath, so surface stains and deeper discolouration can both fade. A dentist can supervise it in the chair or set you up with custom trays to use at home.
The main thing to know is that whitening lifts the shade of your own teeth. It does not change the colour of fillings, crowns or veneers. That single fact shapes a lot of the advice below.
How professional teeth whitening works
The active ingredient is usually hydrogen peroxide or carbamide peroxide. It breaks down and reaches the stained molecules inside the tooth. The shade lifts over a series of applications. Stronger gels are only available through a dentist because they need care around your gums and any exposed roots.
There are two common paths.
- In chair whitening. Done in one visit with a higher strength gel and gum protection in place. Good if you want a quicker start.
- Take home trays. We take an impression, make trays that fit your teeth exactly and give you gel to use over one to two weeks at home. Slower, more control, easy to top up later.
Over the counter strips and generic trays exist too. They are weaker and the one size trays let gel spill onto the gums, which is where a lot of the sensitivity complaints come from.
Why a check up comes first
Whitening gel sits on your teeth for a while, so the teeth and gums need to be healthy before you start. A quick exam picks up decay, cracks, gum problems or worn enamel that could sting badly if gel gets in. If you have a cavity, that gets sorted first.
An exam also tells us whether whitening is even the right tool. Grey discolouration from an old root canal, staining inside the tooth or heavy fluorosis often respond differently. Sometimes a different cosmetic dentistry option in Geelong suits better. Results vary from person to person and no dentist can promise a set number of shades.
Whitening, veneers and crowns
Here is the part people miss. If you plan to whiten and you have front fillings, crowns or veneers, whiten first. Then any new dental work can be colour matched to your brighter shade. Do it the other way round and the older restorations will look darker against the rest.
For teeth that are chipped, worn or badly stained inside, whitening alone may not get you there. That is when porcelain or composite veneers in Geelong come into the conversation, or a broader smile makeover in Geelong if several teeth are involved. A good starting point is a chat with your dentist in Geelong about what your teeth can realistically do.
What it costs and how long it lasts
Cost depends on the method you choose, how many teeth are treated and whether you go in chair or take home. We give you a written estimate after the exam so you are not guessing. Some health funds put a rebate toward whitening under general or cosmetic dental and payment plans may be available, so ask when you book.
Results are not permanent. Coffee, tea, red wine and smoking all pull the colour back over months. Teeth also darken naturally with age. Custom trays make top ups simple because you keep them. Sensitivity is the most common side effect and it usually settles within a day or two.
Common questions
Does teeth whitening hurt?
Most people feel some short lived sensitivity to cold, not pain. Dentist supervised whitening with well fitting trays and gum protection keeps this to a minimum and it fades quickly.
How white will my teeth get?
It depends on your starting shade and the cause of the staining. Yellow tones tend to lift well, grey tones less so. An exam gives you a realistic idea before you spend anything.
Can I whiten if I have crowns or veneers?
Your natural teeth will whiten but the crowns and veneers will not change colour. If you are anxious about treatment, ask us about sedation dentistry options as well.
