Professional In-Clinic Teeth Whitening in Wellington
A radiant, bright smile can make a world of difference to your confidence and how you interact with others. Over time, however, it is entirely normal for our teeth to lose their natural brilliance. Factors such as ageing, coffee, tea, red wine, tobacco use, and certain medications can cause teeth to become stained, yellowed, or dull.

If you are looking to lift deep stains and dramatically lighten the shade of your teeth, our professional in-clinic teeth whitening services at Newtown Dental offer a fast, safe, and highly effective solution.
Why choose in-clinic whitening over at-home kits?
While supermarkets and pharmacies are filled with over-the-counter whitening strips and toothpastes, these products are legally restricted to using very low concentrations of whitening agents. As a result, they often take weeks to show minimal results and can cause uneven whitening or gum irritation if applied incorrectly.
When you opt for professional in-clinic whitening at Newtown Dental, you benefit from:
- Immediate, Dramatic Results: We use professional-grade whitening gels that are significantly stronger than retail products. This allows us to lighten your teeth by several shades in just a single, one-hour appointment.
- Safety and Comfort: Because the procedure is overseen by a qualified dental professional, we take precise steps to protect your gums and soft tissues from the bleaching agent, minimising sensitivity and preventing chemical burns.
- Customised Treatment: We assess the specific type of staining on your teeth (extrinsic vs. intrinsic) and tailor the concentration and duration of the treatment to achieve your desired shade safely.
What is the teeth whitening process?
Achieving a brighter smile at Newtown Dental is a relaxing and straightforward process:
Preparation
We carefully apply a protective barrier over your gums and lips, leaving only your teeth exposed.
Application
We apply the professional-grade whitening gel to the surface of your teeth. Depending on the system used, a specialised light may be positioned over your teeth to activate the gel and accelerate the bleaching process.
The Reveal
After the gel has done its work (usually applied in two or three 15-minute intervals), we remove the barrier and reveal your instantly brighter smile.
How much does teeth whitening cost?
Professional teeth whitening is one of the most cost-effective ways to dramatically enhance your smile. During your consultation, we will discuss the exact cost of the in-clinic procedure. We also offer take-home maintenance kits with custom-fitted trays so you can touch up your smile at home before special events.
We accept a range of payment options, making it easy to invest in your confidence.

FAQs
Frequently asked questions
Does teeth whitening cause sensitivity?
It is common to experience some temporary tooth sensitivity to hot and cold temperatures for 24 to 48 hours following a professional whitening treatment. We take steps to minimise this during the procedure, and the sensitivity will subside naturally.
How long do the whitening results last?
The longevity of your results depends heavily on your lifestyle habits. If you frequently consume coffee, tea, red wine, or smoke, stains will accumulate more quickly. With good oral hygiene and occasional at-home touch-ups, professional whitening results can last for a year or more.
Can anyone get their teeth whitened?
Most adults with healthy teeth and gums are excellent candidates. However, whitening is not recommended for pregnant or nursing women, children under 16, or patients with active gum disease, severe enamel erosion, or untreated cavities. We will confirm your suitability during your initial assessment.
