Teeth Whitening

Enjoy a whiter and healthier-looking smile that lasts with a teeth whitening professional.

  • Professional Teeth Whitening

    Sometimes a dull or discoloured smile indicates plaque build-up, but this isn’t always the case. In fact, brushing and flossing alone won’t always prevent teeth from yellowing, which occurs naturally as we age.

    If you want safe and reliable teeth whitening that won’t harm sensitive teeth, our experienced dentists can provide quick and effective treatment for a brighter, healthier-looking smile.

    • ZOOM! Take-home whitening kits
    • ZOOM! Top-up whitening syringes

  • Why See a Dentist for Teeth Whitening?

    There are so many whitening products on the market that can cause confusion about what works and what’s right for your smile.

    Professional whitening treatment provided under the supervision of a registered dentist is safer and more effective than over-the-counter products from supermarkets and beauty clinics. This is especially the case for people with sensitive teeth.

    When you choose to have your teeth professionally whitened by a dentist, they’ll take impressions of your teeth to create custom-designed trays that precisely fit over your mouth. Using custom-made trays reduces the risk of gel leaking into gums and causing irritation.

  • In-chair Teeth Whitening

    In-chair teeth whitening uses a higher concentration of whitening gel and laser light to brighten tooth enamel. Results are almost immediate, allowing you to achieve up to 8 shades whiter teeth in just 45 minutes.^

    If you’re looking for immediate results, we recommend in-chair whitening and can refer you to our sister practice EVP Dental in East Victoria Park, who provides in-chair whitening treatment to our patients. Please note, for best results in-chair whitening treatment needs to be followed by home whitening to maintain your desired shade.

    ^Excludes preparation time. Research conducted in the US using 25% HP Zoom! Kit, funded by Discus Dental

Frequently asked questions

Professional teeth whitening treatment doesn't last foreever. However, when usingcustom-made trays under the supervision of a qualified dentist results may last between 6 months to 1 year. You can top up as you go and maintain whiteness for longer with some simple tips:

  • Avoid smoking
  • Avoid consuming food and drinks that stain teeth (sauces, curries, beetroot, coffee, tea, red wine
  • Rinse with water after eating 
  • Drink through a straw (if consuming dark-coloured beverages)
  • Brush twice a day
  • Floss once a day

Home whiteing treatment from Mount Lawley Dental costs $399. 


If you’ve recently completed in-chair or professional home whitening, you’ll want to keep your white smile for as long as possible. You can maintain a whiter smile by:

  • Using a touch-up whitening pen or top-up syringes
  • Using a whitening toothpaste
  • Avoiding drinks that stain, like red wine, coffee, black tea and soft drinks
  • Brushing your teeth twice daily
  • Flossing between your teeth once a day
  • Drinking plenty of water to wash away bacteria

If you’re concerned about tooth sensitivity, you may decide to choose a product that is specifically designed for sensitive teeth. Mount Lawley Dental uses Philips ZOOM! Nite White – which is especially formulated for those with sensitive teeth.

It’s common to experience tooth sensitivity within the days following a whitening treatment, however the sensation should disappear within the week.

If the whitening gel comes into contact with gums and soft tissues it can burn or cause irritation. If you have worn-down or cracked teeth, you may also be prone to sensitivity.

This is why seeing a dentist for whitening treatment is a safe option, they create custom-made trays to reduce these risks.

In Australia, all home whitening products contain less than 6% hydrogen peroxide or 18% carbamide peroxide and are considered safe for use at home.

A professional teeth whitening kit provided by a registered and qualified dentist is the safest option for teeth whitening. This is because the process involves a face-to-face check-up to identify dental issues prior to treatment and will involve custom-made whitening trays designed to perfectly fit your mouth, reducing the risk of gum irritation from chemical burns. 

One of the most common causes for yellowing teeth is aging. Under your tooth enamel is an inner layer of the tooth called dentin that is yellow in colour. As you age, your tooth enamel becomes thinner, exposing the yellow dentin beneath.

Other causes for stained or discoloured teeth include surface stains and internal stains. Surface stains include:

  • Plaque and calculus
  • Tar from tobacco
  • Tannins from red wine, tea and coffee
  • Too much mouthwash (more than the recommended amount)

Internal Stains are pigments within the internal tooth structure and occur during or after teeth develop. Internal stains can occur due to:

  • Illness and fever
  • Antibiotic use (Tetracycline)
  • Medical conditions
  • Excessively high fluoride levels
