We've got the answers to some of our most commonly asked questions below.

General Questions 🤔

Caps, implants, bridges, veneers, or bonding aren’t designed to be whitened and require special care from your dentist.

The Powder and PAP Whitening Strips™ work to remove both internal and external stains from natural teeth. This means they will help keep your surrounding teeth the same shade as those that have had dental work.

Teeth Whitening Powder 🪥

Pentasodium Triphosphate

A highly effective, proven stain remover, which safely dissolves stains in the enamel. It also prevents common stains, such as those from coffee, wine, smoking etc, from building up on the teeth, post-treatment.

Calcium Carbonate

An enamel-safe, gentle abrasive that works to remove plaque, debris, and surface stains to clean the tooth's surface. This is the ingredient that will give you that dentist-clean feeling.

Strontium Chloride Hexahydrate

Safely forms a protective barrier over the delicate nerve endings in the teeth to ensure zero pain or sensitivity, during or after treatments.

List of Ingredients

Calcium Carbonate, Pentasodium Triphosphate, Menthol, Sodium Lauryl Sulfate, Sodium Saccharin, Mentha Viridis Leaf Oil, Allantoin, Strontium Chloride Hexahydrate.

The Whitening Powder is 100% safe on tooth enamel. Thanks to its peroxide-free and low abrasive formula.

It's no more abrasive than your standard toothpaste and works by utilising a non-abrasive ingredient called Pentasodium Triphosphate - a highly effective stain remover that works by gently dissolving stains from the tooth's surface.

We commonly hear of people using 100% sodium bicarbonate and charcoal products as an alternative. However, what many fail to mention is that they don't contain an ingredient like Pentasodium Triphosphate. Instead, they solely rely on their abrasive nature, which over time can cause irreparable damage to the teeth through the gradual stripping of tooth enamel.

Not at all. Our Whitening Powder has been formulated with an ingredient clinically proven to prevent sensitivity. It's called Strontium Chloride Hexahydrate, and it works by safely forming a protective barrier over nerve endings in the teeth.

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 and dip it into the powder, ensuring all bristles are evenly coated.

2.Brush for 4 minutes, allowing each quarter of your mouth 1 minute of brushing.

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

The MySweetSmile® Powder should be used 1-2 times a week to remove stubborn stains and prevent the build-up of new stains from daily consumption of tea, coffee, wine, nicotine, 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 6 months, when used 1-2 times a week as directed.

PAP Whitening Strips™ 🦷

When applied to your teeth, each strip firmly adheres to the tooth surface and begins to release the active ingredients of the formula into the tooth’s structure to provide fast whitening results from the very first treatment.

The active whitening ingredient, PAP, enters through the enamel of the teeth and gently breaks down stain molecules into smaller forms. The smaller the molecule, the lighter in colour it is, resulting in an overall whiter tooth.

Traditional whitening strips use a peroxide-based formula that can trigger tooth sensitivity and gum irritation. MySweetSmile® PAP Strips instead utilise a sensitivity-free PAP-based formula, 100% free from peroxide.

Peroxide-based formulas work through a process known as free-radical oxidisation. Which, when not administered under dentist supervision, can cause severe sensitivity, irritated gums, and demineralisation of your tooth enamel.

PAP similarly reacts with tooth stains, only without the release of free radicals. This means that the molecules responsible for discolouration are broken down safely, without any risk of sensitivity, pain, or damage to the enamel.

Phthalimidoperoxycaproic Acid (PAP)

As the key whitening ingredient in our Teeth Whitening Strips, PAP is scientifically proven to be a safe alternative to peroxide. It has no negative side effects during the oxidation (removal) of tooth stains which allows it to effectively whiten teeth without pain or sensitivity.


Polyvinilporrolydone, or PVP for short, is a protective ingredient that keeps stains away from the tooth surface. This means not only do our Teeth Whitening Strips remove stains, they also prevent them from building-up again.

Sodium Hydroxide

Sodium Hydroxide is a commonly used ingredient in teeth whitening, since it safely and gently removes stains from within the enamel layer.

List of Ingredients

Glycerin, PVP, Ethylcellulose, Phthalimidoperoxycaproic Acid, Alcohol, Hydrated Silica, Dicalcium Phosphate, Disodium EDTA, Sodium Hydroxide, Menthol.

1. Peel open sachet to reveal two whitening strips.

2. Place the smaller strip on your bottom teeth, and the larger strip on your top teeth. Tuck away any overhanging strip behind the teeth to ensure even whitening.

3. After 30 minutes, peel the strips off and rinse away any residual gel. Then, brush with your regular toothpaste for 2 minutes.

Our PAP Whitening Strips™ deliver whitening results after a single 30-minute treatment. Afterwards, based on your results, you can decide whether you want to continue using the strips for fourteen consecutive days or save the remaining strips for future treatments as and when you feel your teeth need a whitening boost.

Our PAP Strips have a predominantly neutral taste, with a slight hint of mint.

We do not recommend leaving the PAP Strips on overnight. We recommend using for 30 minutes per treatment only.

A build-up of excess saliva while using the PAP Strips is completely normal and won't affect the outcome of the whitening process at all. If you find that the build-up of saliva is becoming too much during your applications, simply expel any excess into the sink. Our formula is made with safe ingredients so if you accidentally consume a small amount of formula during your applications it won’t be a problem.
