Teeth Whitening Powder 🦷

We've put together some of our most commonly asked questions about our Teeth Whitening Powder

Our Teeth Whitening Powder works by gently dissolving and removing stains from the tooth's enamel surface, to reveal whiter, brighter, and cleaner teeth from the very first treatment.

The MySweetSmile Teeth Whitening Powder can remove all types of stains. Some common ones are those caused by tea, coffee, wine, and tobacco/nicotine.

1. Lightly dampen your toothbrush.

2. Dip your toothbrush head into the powder, ensuring all bristles are evenly coated.

3. Brush for 4 minutes, allowing each quarter of your mouth 1 minute of brushing. Avoid your gums.

4. Rinse your mouth and follow by brushing with your regular toothpaste.

Repeat once daily, for 14 consecutive days.

If it's your first time using our Teeth Whitening Powder we recommend completing a 14-day course, consisting of one treatment per day.

After this 14-day course, simply complete 2-3 treatments per week. In order to maintain your initial results, and combat the build-up of 'new' stains from tea, coffee, wine etc.

The MySweetSmile Teeth Whitening Powder contains Spearmint Oil for a slight minty taste, that'll leave you with fresh breath all day.

Each tub of Teeth Whitening Powder will last up to 4 months.

However, if it's your first time using the Teeth Whitening Powder you'll need to complete a 14-day course, which means your first tub will last for up to 2.5 months.

Not at all, our Teeth Whitening Powder has been formulated with a special ingredient called Strontium Chloride Hexahydrate, which was specifically added for its ability to prevent pain or sensitivity.

It works by safely forming a protective barrier over nerve endings in the teeth to ensure zero pain or sensitivity, before or after treatments.
