Tips & Tricks

For best results, try the following:

  • Brushing your teeth thoroughly and then drying them with a clean, dry face cloth before applying the teeth whitening gel
  • Rubbing a small amount of the teeth whitening gel over your teeth with your finger before placing the mouthguard in your mouth
  • Applying pressure to the mouthguard during the application process (you can also extend your lips over the mouthguard to avoid holding in place with your hands)
  • Do your applications just before bed so your freshly whitened teeth have a break from food and drink stains
  • Avoid dark coloured food and drinks during your 6-9 applications

Frequently Asked Questions

What is unique about HiSmile's formula?

We have carefully crafted a formula that uses 3 Primary Whitening Agents to ensure maximum results and assist in gently whitening all inner and outer tooth stains. Our gel was designed to optimize all of its whitening effects within only 10 minutes whilst maintain no damage to the tooth’s enamel.

Through our unique formulation we have also been able to ensure that no tooth erosion occurs and that the tooth’s enamel is not damaged in the process.

How do I use HiSmile's teeth whitening products?

How do I use the Teeth Whitening Kit?

Simply apply the teeth whitening gel to the walls of the mouth guard, place in your mouth against your teeth and turn the light on. After 10 minutes, the light will turn off and beep. Rinse your mouth and mouth guard.

The teeth whitening kit will give you 6-9 applications (2-3 applications per syringe). We recommend using the kit consecutively for 6 days for first time users to achieved optimum results, then only once fortnightly to maintain your results.

How do I use the Teeth Whitening Pen?

Remove the cap and twist at the bottom to push the formula into the bristles, then paint onto your teeth wherever you need to whiten.
The teeth whitening pen is perfect for touch ups on the go and whitening those harder to reach areas such as between your teeth.

How do I use the Coconut Whitening Mouthwash?

Squeeze 1/3 of the tube of Coconut Mouthwash into your mouth and swirl for two minutes, then rinse your mouth with warm water.
We recommend you use our Coconut Mouthwash every other day after brushing your teeth.

The Ultimate HiSmile Routine

We recommend brushing your teeth then using your HiSmile Teeth Whitening Kit. Once you’ve finished your application, follow up with our Coconut Mouthwash. For optimum results, apply the Teeth Whitening Pen as your final step.

How often do I have to whiten my teeth?

After completing the first course of 6-9 applications, we recommend 1 application fortnightly to maintain optimum results.

Our Gel pack comes equipped with one month's supply to easily maintain your initial results.

How long will the results last?

Results will vary per person depending on your teeth and your eating/drinking habits. However, results from completing the recommended 6-9 applications will generally last 1-3 months.

Will it cause sensitivity or damage?

No. With the addition of Sodium Bicarbonate to our teeth whitening gel, a high PH level is maintained, meaning that our gel is not acidic.

This ensures that no sensitivity, tooth erosion or enamel damage is encountered whilst still maintaining maximum whitening results.

How does the LED light whiten my teeth?

Our unique gel formulation breaks down its bleaching radicals quicker under the LED Light. This is what makes our application time so fast and effective, delivering results in only 10 minutes.

Do I need to see a dentist?

HiSmile's teeth whitening kits can be used completely in the privacy of your own home. Our products are so easy to use that you are ensured a convenient and mess-free application process every time.

Veneers, Braces, Caps, Crowns?

Our teeth whitening products will only remove stains from real teeth.

We recommend waiting until you have your braces removed before using HiSmile, as you will not achieve consistent results.

Is it safe to use if I'm pregnant or breastfeeding?

For precautionary reasons we recommend consulting your GP first. Feel free to email us for a list of ingredients to give to your doctor.

What does the Coconut Mouthwash do?

Our Coconut Mouthwash helps remove the plaque from your teeth, keeps your gums healthy and your breath smelling fresh! Oil pulling also has many more benefits for you body, as it has a powerful detoxifying effect.

Coconut oil will naturally solidify in colder temperatures. Simply run the tube under warm water to return your mouthwash back to its liquid state.
