Introduction
If you’re considering a teeth whitening kit in Australia, you probably want to know whether it actually works and whether it’s safe for your teeth. Teeth whitening kits can deliver effective results, particularly dentist-supervised take-home kits, while over-the-counter options are convenient but usually slower and less predictable.
In this guide, we’ll explore the different types of whitening kits, explain how they work, their costs, potential risks, and how long they take to show results. We’ll also compare at-home kits with professional in-chair treatments so you can make an informed choice.

Types of Teeth Whitening Kits
Over-the-Counter Whitening Kits
These kits are widely available at pharmacies and online retailers. They generally contain mild peroxide-based gels or whitening strips and are designed for easy home use. While they can lighten stains, results are usually slower and less uniform compared to dentist kits.
Dentist Take-Home Whitening Kits
Dentist take-home kits use custom-fitted trays that ensure the whitening gel covers your teeth evenly. With higher concentrations of peroxide than OTC kits, they deliver safer and more consistent results. The typical cost ranges from AUD 200–500 depending on the clinic.

LED-Enhanced Whitening Kits
Some whitening kits include LED lights that claim to accelerate the process. While LED lights may slightly boost the effect, the concentration of the gel is the main factor determining results. These kits can be OTC or dentist-supervised.
How Teeth Whitening Kits Work
Quick Answer
Whitening kits use peroxide-based gels to break down stains on the enamel caused by foods, drinks, and lifestyle habits.
- Carbamide Peroxide releases hydrogen peroxide slowly, ideal for home use
- Hydrogen Peroxide is stronger and faster, used in professional kits
- Stains are oxidised and lightened without damaging the enamel
If you’re unsure which option is right for you, our team at The Avenue Dental can provide guidance.
How Long Does a Whitening Kit Take to Work?
- OTC kits: Typically 1–4 weeks to notice visible results
- Dentist take-home kits: Usually 1–2 weeks for a noticeable improvement
Factors affecting results include the type of stains (surface vs deep), usage frequency, oral hygiene, and diet. Avoiding coffee, tea, red wine, and smoking during treatment helps achieve the best results.
Are Teeth Whitening Kits Safe?
Quick Answer
When used correctly and within recommended concentrations, teeth whitening kits are generally safe. Dentist-supervised kits are the safest choice because they reduce the risk of gum irritation and uneven results.
Potential side effects:
- Temporary tooth sensitivity
- Gum irritation if gel touches soft tissue
- Uneven whitening with poorly fitting trays
Safety tips:
- Follow the instructions carefully
- Avoid overuse
- Use fluoride toothpaste to reduce sensitivity

Comparing Kits to In-Chair Treatments

| In-Chair Whitening | 1–2 hours | Immediate, dramatic | 500–1000+ | Requires clinic visit |
