Teeth Whitening

With years of experience whitening smiles in Baulkham Hills, we’ve explored the latest research and advancements in whitening science. That means we can confidently offer a method that delivers noticeably brighter results.

Unlike many over-the-counter options, we offer dentist-grade whitening systems with custom-made trays that seal snugly to your teeth and professional-grade gels selected specifically for your needs. Teeth whitening in Norwest is one of the most affordable and non-invasive ways to enhance your smile, and we’re pleased to offer it right here in Norwest.

How Does Teeth Whitening Work?

There are two types of stains that affect your teeth:

  • Extrinsic stains sit on the tooth surface and come from everyday foods and drinks like coffee, tea, red wine or from smoking. These can usually be removed during a professional clean.
  • Intrinsic stains lie deep within the tooth. They’re caused by long-chain colour molecules that bind within the enamel. Regular brushing or polishing can’t reach them.

What Causes Intrinsic Stains?

  • Genetics — Just like eye colour, your natural tooth shade is inherited.
  • Age — As we age, the pulp inside the tooth shrinks and dentin thickens, darkening the tooth from within.
  • Staining Foods and Drinks — Colour molecules soak into the enamel and connect over time, becoming darker and harder to remove.

Professional whitening products, such as those containing hydrogen peroxide or carbamide peroxide, break down these deep molecules into smaller, white ones. The key to long-lasting results is allowing enough time for the gel to penetrate deeply into the tooth structure.

Benefits of Professional Teeth Whitening

Over time, teeth can lose their natural whiteness due to coffee, tea, wine, smoking and even certain medications. While over-the-counter products promise quick fixes, they often fall short in both results and safety. Professional teeth whitening in Norwest, NSW, offers a reliable, fast and dentist-supervised way to achieve a noticeably whiter smile.

Safe, Customised Treatment
Unlike generic whitening kits, professional whitening is tailored to your specific needs. Your Norwest dentist will assess your teeth and gums to ensure you're a good candidate and adjust the treatment strength for optimal comfort, safety and results.
Faster, More Noticeable Results
In-chair whitening treatments can brighten your smile by several shades in just one visit. You’ll leave our Norwest dental clinic with an instantly fresher, more radiant look. It's ideal for special events, job interviews or simply boosting your everyday confidence.
Longer-Lasting Whiteness
Professional whitening uses high-quality products that penetrate deeper than store-bought options, breaking down stubborn stains at the source. With good at-home care and occasional touch-ups, your bright smile can last much longer than the results from over-the-counter solutions.

Frequently Asked Questions

Our research into the literature explains it. Extrinsic stains are commonly on the tooth's surface from food like tea, coffee, red wine or smoking. These surface stains can be removed. However, intrinsic stains come from colour molecules inside the tooth and are impossible to clean with regular external polishing.

The reasons for intrinsic colour are varied:

Born This Way

Occasionally, tooth colour is just something in our genetics like hair, skin and eye colour. Our teeth erupt already containing organic debris in the microstructure of the enamel and a genetic colour in the dentine, both giving the tooth its colour.

Age

Another possibility is that as we age, the pulp nerve and blood vessels) shrinks, and dentine increases in size and can be yellow or brown within the tooth. With age, the colour molecules keep joining together, creating longer and darker molecules. Sitting inside the tooth, they make an overall increasing yellow or darker hue to our smiles.

Absorbed Over Time

Also, with time, our teeth pick up organic debris the soaks into the microstructure of the enamel. The stain molecules link like magnets, getting longer, going deeper and becoming darker as we age.

These colours are chemically long-chain pigments. The atoms have tight bonds called chromophores which absorb light, making the tooth look darker. This material can't be removed with surface polishing at the dentist or abrasive toothpaste-like charcoal or whitening toothpaste.

The aim of professional whitening products containing either hydrogen peroxide or carbamide peroxide is to break down to oxygenate and disintegrate and convert these long and dark molecules deeply into the microstructure of all the teeth. It's cleaning the tooth from the inside by penetrating the tooth structure, breaking up the long-chain molecules that are plugging up the prismatic and crystalline structures of the tooth.

The byproducts of the whitening gel break down into oxygen and free radicals, which travel through the tooth via water molecules that then act to break the chromophore bonds. The long molecule is converted into small white molecules. These reactions need to penetrate deep into the enamel and the dentine to break down the stain molecules.

Many factors may have come into why your teeth whitening didn't work as well as you hoped.

  • The right product and concentration, and the proper method and duration, weren't chosen for your particular needs.
  • Your trays were leaking, allowing the whitening product to leak out or saliva leak in and break down the product. Saliva actually breaks down your whitening product.
  • The product degraded and was compromised by the conditions it was transported or stored in. By virtue of being a product designed to break down to work, whitening products are notoriously unstable.
  • The product is expired.
  • The product is too thick to be available to get into the tooth's microstructure.
  • Your teeth have absorbed more organic long-chain stains, and it's time to whiten with a new method.

Teeth that don’t look natural often aren’t natural. They might be fake veneers or dentures. Whitened teeth are your own teeth, just beautifully lightened. They will look like you.

We invite you to call 02 8610 6697 to arrange your appointment with Willow Care Dental or ask further questions about teeth whitening treatments.

It is normal to get a little regression in the first 2 weeks after whitening as the whitening bubbles exit the tooth. From here typically the results can last one to four years, depending on the amount of staining beverages like wine, tea and coffee that the teeth are exposed to over time. Long term people can get reabsorption of stain molecules. If you enjoy your coffee tea and red wine we suggest a periodic maintenance programme.

There has been no association of nerve or pupal damage to teeth or damage to the structures of the teeth using whitening gels as designed. Unfortunately, laser whitening cannot say the same.

It is relatively common for you to experience increased cold sensitivity while you whiten. However, this is not a lingering problem, and our whitening system has a special desensitiser to apply during your treatment.

Whitening products also do not whiten your fillings or crowns. As a result, some people find they will need to replace certain fillings to get the white, natural look they are after.

Why Choose Professional Teeth Whitening?

At Willow Dental Care, we tailor your whitening treatment to suit your needs. What makes professional whitening more effective?

  • Stronger, dentist-only gels that aren’t available at pharmacies or salons
  • Precise custom trays that keep the gel in close contact with your teeth
  • Safe, controlled application to reduce sensitivity and protect your gums
  • Ongoing support from a trusted dental team

The effectiveness of whitening depends on:

  • The strength of the peroxide gel
  • How long the gel stays on your teeth
  • The quality and freshness of the product

Our team selects only scientifically supported products and protocols, avoiding fads or gimmicks that could put your comfort at risk.

At-Home Whitening: Our Most Recommended Option

Our preferred method is take-home whitening with custom trays, which offers the best balance of safety, comfort and results. At Willow Dental Care:

  • We use cold-stored whitening gels to preserve their potency.
  • Each tray is custom-designed to fit your teeth precisely and seal properly.
  • A desensitising agent is included to reduce sensitivity.
  • Most patients wear the trays overnight for two weeks, depending on their starting shade.

Research shows that slow, steady whitening using a lower concentration of peroxide is not only safer, but produces results that last longer. That’s why we focus on at-home whitening as our gold standard.

In-Chair Whitening: For Deeper Stains or Tight Timelines

In-chair whitening may be suitable if:

  • You need fast results for an upcoming event.
  • You can’t tolerate wearing trays overnight.
  • You have deeply stained teeth (e.g., tetracycline staining).

We follow evidence-based protocols and do not use lights or lasers, which have been shown to increase sensitivity without improving results. Your comfort and long-term tooth health are our top priorities.

We’ll take before-and-after photos so you can see your transformation and share your new smile with friends and family in Baulkham Hills, Norwest, Bella Vista, Kellyville, Castle Hill, Glenhaven, Rouse Hill and Glenwood.
