What is professional teeth whitening?
Professional teeth whitening is a treatment that makes your teeth whiter. It uses a strong gel that only dentists can use. The gel removes stains from coffee, tea, wine, or smoking. Dentists apply it carefully to protect your gums and get even results.

It’s safe, quick, and works better than store-bought products. Most people see whiter teeth after just one visit. Whitening gives you a bright, fresh smile and more confidence. It’s a popular choice before weddings, parties, or job interviews.

How does it work?
1. Initial Check-up
Your dentist checks your teeth and ...
... gums to make sure whitening is safe for you. This takes about 10 to 15 minutes. It helps find problems like cavities or gum disease that need fixing first. Only healthy teeth and gums can handle whitening without pain or damage.

2. Cleaning
A professional clean removes plaque and stains to help whitening work better. It includes scaling and polishing for smooth, clean teeth. Cleaning helps the gel spread evenly and whiten your teeth more effectively. It’s an important step to get even, long-lasting, and bright results.

3. Gum Protection
Your dentist places a protective barrier to shield your gums during the whitening process. This prevents irritation, burning, or sensitivity from the whitening gel. The barrier ensures comfort while allowing the gel to stay on longer if needed. It’s essential for a safe, gentle experience without damaging soft gum tissues.

4. Whitening Gel Application
A strong whitening gel is carefully applied to the front surfaces of your teeth. Each application stays on your teeth for around 15 to 20 minutes. Multiple rounds may be done depending on your stains and desired brightness level. Your dentist monitors progress closely to avoid over-whitening or tooth sensitivity issues.

5. Light Activation (Optional)
Some clinics use special lights or lasers to speed up whitening. This adds 10 to 15 minutes to the treatment time. The light helps the gel break down stains faster and deeper. Not all clinics use this, but many patients feel it works better.

6. Waiting Time
After the gel is applied, it stays on for 15 to 30 minutes. Your dentist checks that you’re comfortable and watches the progress. You may feel a small tingle – that means the gel is working. This step helps make your smile bright and even.

7. Rinse and Check
Once whitening is done, Your dentist gently rinses off the remaining whitening gel. They check the colour and compare it to your initial shade before treatment. This takes about 10 minutes and confirms if further whitening sessions are needed. You’ll instantly notice a whiter smile and fresher look right after this step.

8. Aftercare Advice
Your dentist shares practical tips to help you keep your smile bright and clean. Avoid dark drinks like coffee or red wine for at least 24 hours afterwards. Maintain great hygiene and visit your dentist regularly for long-lasting whitening results. Simple habits can protect your smile and make whitening results last much longer.

Is it safe for your teeth and gums?
Professional teeth whitening is safe when done right. Our dentists use top-quality products that meet safety rules. They put a protective cover on your gums before using the gel. You might feel a little sensitivity after, but it usually goes away quickly.

Professional Teeth Whitening vs Store-Bought Whitening Kits
Professional whitening is stronger and works faster than store kits. your dentists use high-strength gels that aren’t available in pharmacy or supermarket whitening products. Your treatment is customised and safely monitored to protect your teeth and gums. Store-bought kits work more slowly, may irritate, and often lead to patchy or uneven results.

Is it worth the time and money compared to DIY options?
Professional whitening costs more than DIY kits, but it gives faster, better results under dentist supervision. DIY kits are cheaper but take longer and can cause uneven whitening. Many Aussies think the extra cost is worth it for a brighter, hassle-free smile. If you’re on a budget and have mild stains, a home kit might work, but for bigger results, professional whitening is usually best.
