Teeth Whitening Overview

Teeth Whitening is among the most popular cosmetic dental procedures because it can greatly improve how your teeth look. Whitening is not a one-time procedure. It will need to be repeated from time to time if you want to maintain a whiter shade.

Teeth whitening is a simple process. Our whitening gels contain one of two tooth bleaches (hydrogen peroxide or carbamide peroxide). These bleaches break stains into smaller pieces, which makes the colour less concentrated and your teeth brighter.

Preparing your teeth for a whiter smile:

It is important to have your gum health checked before using the tooth whitening bleach solution.  Whilst it is very safe for oral use, it could cause sensitivity on infected or inflamed gums.  If you are a new patient to Boyne Dental or have not had a full dental exam in 12months or more, you will be encouraged to make an appointment with one of our dentists to complete an exam.  Our dentist will take impressions of your teeth at this appointment.

Your dentist may encourage you to visit one of our hygienists before commencing any tooth whitening procedures.  The reasons for this is simple:

  • to manage your gum health
  • to remove plaque or excessive staining (no point in bleaching tea stains….get these removed and let the tooth whitening gel do the real work!)
  • to offer advice on the best way to maintain your whiter smile, through use of correct brushes etc.

Once your dentist is happy with the condition of your teeth, you will be invited to to return for your whitening trays which will have been made for you in our on-site laboratory.    You will be shown how to dispense the whitening gel and fit the trays.  You will start to notice your teeth whitening within a week of using the gels. Once you find a shade you are happy with, start reducing your usage. You can buy individual top-ups with us here in Boyne Dental which are very handy for special occasions when you want your smile picture perfect.

Additional Information


Although treatment results can be rapid, stains can reappear within the first few months and years after treatment. In order to maintain your whitened smile, there are multiple ways to protect your teeth and prolong the treatment

  • Brush or rinse your mouth immediately after eating and drinking.
  • Floss to remove plaque.
  • Use whitening toothpaste once or twice a week to avoid surface stains.
  • Do visit the dentist for touch up treatments.

Does whitening work on all teeth?

No, which is why it’s important to talk to your dentist before deciding to whiten your teeth, as whiteners may not correct all types of discoloration. For example, yellow teeth will probably bleach well, brown teeth may not respond as well and teeth with gray tones may not bleach at all. Whitening will not work on caps, veneers, crowns or fillings. It also won’t be effective if your tooth discoloration is caused by medications or a tooth injury.

It is highly advised that before you begin any whitening treatment, that you should visit with a hygienist to ensure that you are allowing your teeth the best possible chance at brightening. Whitening stained teeth will only just mask whatever issues may be developing underneath.

Are there any side-effects with whitening?

Some people who use teeth whiteners may experience tooth sensitivity. That happens when the peroxide in the whitener gets through the enamel to the soft layer of dentin and irritates the nerve of your tooth. In most cases the sensitivity is temporary. You can delay treatment, then try again.

Overuse of whiteners can also damage the tooth enamel or gums, so be sure to follow directions and talk to your dentist.
