Teeth Whitening Treatment in Adelaide

At Morphett Vale Dental Care, we know that a bright smile can make all the difference in your confidence and wellbeing. Everyone’s teeth are unique in shape, colour, and how they respond to daily habits. Over time, teeth can naturally become discoloured due to age, diet, smoking, certain medications, trauma, or even just everyday wear and tear.

Teeth whitening (also called bleaching) is one of the simplest and most popular cosmetic dental treatments. It’s a safe, non-invasive way to lighten the natural enamel of your teeth and refresh your smile.

Reasons people choose teeth whitening include:

  • Yellow or brown staining
  • Enamel discolouration
  • Fluorosis (excess fluoride exposure during tooth development)
  • Normal wear of enamel
  • Staining caused by certain medications

Take-Home Whitening

Prefer to whiten your teeth at home at your own pace? Take-home whitening may be the right choice.

With this option, we create custom-fitted whitening trays designed specifically for your teeth. You’ll receive professional-grade whitening gel and clear instructions on how to use it safely at home.

What’s involved:

  1. We take impressions to make your trays.
  2. After about a week, you’ll collect your trays along with whitening gel and instructions.
  3. At home, you’ll wear the trays with gel once a day for about 30 minutes, over 2–3 weeks.

This gradual process allows you to control the degree of whitening while maintaining comfort and safety.

In-Office Whitening

For patients looking for quick results, in-office whitening is one of the most effective options.

At MVDC, we use Pola-Office+ Whitening, a professional system designed to whiten teeth safely and effectively. It’s pH neutral, contains desensitising technology to help protect sensitive teeth, and does not require UV light activation minimising risks such as gum irritation or discomfort.

  • Cleaning & polishing: Your teeth will be prepared to achieve the best results.
  • Protection: Your gums and lips will be shielded with a special barrier.
  • Whitening treatment: Gel is applied and activated with LED light in several short sessions.

Teeth Whitening FAQ’s

Not everyone is suitable for whitening, as it only works on natural teeth. Restorations such as veneers, crowns, or dental bonding won’t change colour with treatment. Whitening is most effective on surface (extrinsic) stains, like yellow or brown staining, but less so on intrinsic stains within the tooth, such as after root canal therapy.

Patients with significant tooth sensitivity may not be good candidates, as whitening can increase discomfort.

Every smile is different, so whitening should always be done under professional supervision. At your appointment, we’ll assess your oral health, discuss options, and let you know whether whitening is a safe and effective choice for you.

The results of teeth whitening aren’t permanent, but with good care they can last anywhere from a few months up to a year. How long your smile stays bright depends on several factors, including your oral hygiene habits and diet. Drinks like coffee, tea, red wine, or habits such as smoking can cause teeth to stain more quickly.

Touch-up treatments can help maintain results, and your dentist will guide you on when (and if) these are appropriate. It’s also important to note that whitening works best on natural teeth, and results vary from person to person.

At Morphett Vale Dental Care, we offer two main types of whitening:

  • In-chair whitening – This treatment is carried out in the dental clinic. It provides faster results as a professional-strength whitening gel is applied under the supervision of your dentist. In a single visit, many patients notice a brighter smile.
  • Take-home whitening – This option involves custom-made trays and a whitening gel you can use at home. You’ll wear the trays for a set period each day over 1–3 weeks. Results are gradual, and this method allows you more control over how white your teeth become.

Both options are safe when supervised by a dental professional, and your dentist can help you choose the approach that best suits your needs.

Take-home whitening, as the name suggests, is done from the comfort of your home using custom-made trays designed by your dentist. Whitening gel is placed in the trays, which you wear either for a couple of hours during the day or overnight, depending on your needs and preference. Treatment usually takes up to three weeks for gradual results.

In-chair whitening is performed at the dental clinic using a stronger professional whitening gel. The main advantage is speed – instead of waiting weeks, you can usually see noticeable results in around 90 minutes.

After whitening, your teeth are more vulnerable to staining for a short time. To help maintain your results, try to avoid tobacco, coffee, tea, red wine, and other strong-coloured foods or drinks for at least 48 hours. It’s also a good idea to avoid very hot or cold foods during this period, as they can increase sensitivity.

Some patients may notice temporary tooth sensitivity after treatment, which usually lasts a few hours to a few days. Your dentist can provide desensitising products or tips to help make this more comfortable.

Our team will provide you with personalised aftercare instructions so you can enjoy your brighter smile with confidence.

Teeth whitening performed under professional supervision should not be painful. Some people may experience temporary sensitivity, but this usually subsides shortly after treatment. Over-using whitening products or not following professional instructions can cause discomfort, which is why it’s always safest to have whitening overseen by a dental professional.

At our clinic, we’ll guide you through every step to keep you comfortable and make the experience as easy as possible.

Yes, whitening outside of a dental clinic can carry risks such as tooth sensitivity, gum irritation, uneven results, or even gum burns if peroxide products are not applied correctly. In some cases, overuse of whitening products may also cause teeth to appear grey.

For your safety and the best results, it’s always recommended to have whitening supervised by a qualified dental professional. We can guide you through the process and tailor treatment to your individual needs.

Some people may experience temporary tooth sensitivity after whitening, especially to hot or cold foods and drinks. This usually settles within a few hours to a couple of days.

If sensitivity occurs, your dentist can recommend desensitising products or tips to make you more comfortable. Most patients find the sensitivity mild and short-lived.

Any sensitivity after whitening is usually mild, temporary, and can be managed with simple care. 

Teeth whitening does not change the colour of fillings, crowns, veneers, or other restorations, it only works on natural tooth enamel. If you are considering whitening as part of a smile makeover, it’s important to plan ahead. Restorations may need to be replaced after whitening to ensure they match the new shade of your natural teeth.

Teeth whitening is generally not recommended for children under 16, as their teeth and gums are still developing and may be more vulnerable to sensitivity or damage. For younger patients, focusing on good oral hygiene and regular professional cleans is the safest way to keep teeth healthy and bright.

The results of whitening vary from person to person and depend on the starting colour of your teeth and the method used. Yellow-toned teeth usually respond well to whitening, while grey-toned teeth may show less change and may require more time or alternative options.

Your dentist will assess your teeth and guide you on what results you can realistically expect.

Results vary between individuals, and no whitening system can guarantee a specific shade.

Smoking can quickly stain teeth again and reduce the benefits of whitening. It also increases the risk of gum disease and other oral health problems. For best results, it’s recommended to avoid smoking for at least one to two weeks after whitening and ideally consider cutting down or quitting for your long-term oral and general health.

Results vary between individuals, and lifestyle habits such as smoking can affect the outcome and longevity of whitening treatment.

You can help keep your smile brighter for longer with a few simple habits:

  • Brush and floss regularly, and rinse your mouth with water after meals or drinks that may stain.
  • Limit dark-coloured drinks like coffee, tea, or red wine — or use a straw to reduce contact with teeth.
  • Avoid tobacco products, which can quickly discolour teeth.
  • Keep up with your regular dental cleans, and consider touch-up whitening when advised by your dentist.

Results vary between individuals, and maintenance depends on diet, lifestyle, and oral hygiene.
