Your one-stop-shop for product qualms and delivery hiccups
All of our products are designed to be gentle on teeth. Smirk Powder contains ingredients that actually calm the nerves and form a barrier over microscopic holes in your enamel, helping with sensitivity. Most users won’t experience discomfort or sensitivity with our Teeth Whitening Strips either, since they are peroxide-free. Discontinue use or consult your dentist if you do experience sensitivity with Smirk strips. All of that being said, if you have bleeding or receding gums, or damaged teeth, please see a dentist before use (they don’t bite!)
Smirk Powder is safe for use while pregnant or breastfeeding. Smirk Strips are not recommended for use while pregnant or breastfeeding.
Sorry, we cannot recommend the use of any whitening products on teeth with fixed braces. You can safely use all Smirk If you’re using a removable clear aligner system.
Smirk Powder is a mild abrasive, it is perfectly safe for use 2 times a week before brushing with your usual toothpaste. We advise a maximum of two applications per week.
In the first week, you can use it once per day. Brush for 3 to 4 mins per-use, then rinse well and use your regular toothpaste. Week 2 onwards, revert to the normal regular use, once or twice a week. This will ensure your enamel is protected, whilst getting smirk-worthy whitening results.
Smirk Strips and Smirk Box can be used daily.
Use with fixed brace isn’t advised. Please wait until your braces are removed before using. Use with a removable brace is fine.
