On my second sweet smile
On my second sweet smile, it will take time. As my teeth are 75 years old. I use it cause I like it, and the difference is slow. But I will still use it. 3 times a week

Save your money
After reading some of the reviews I was reasonably optimistic, however after 3 weeks of following the guidelines I can say there is no difference. Very disappointed in this product and would suggest looking at alternatives before purchasing.

Hi Paul,
Thank you for sharing your experience with us.
The MySweetSmile Teeth Whitening Powder is a gradual, enamel-safe formula, designed to build a healthier, naturally brighter smile over time. It won’t deliver the kind of instant dramatic result you’d get from an in-chair dental treatment. These treatments rely on high-concentration bleaching agents which can only be applied by a dentist in a clinic. They cost considerably more, and the strength of the ingredients means sensitivity is a common side effect.
With that said, we know it doesn’t work for everyone, no product does, just as skincare works differently for every skin type. What we can say is that we’ve seen strong results across our customer base. We’re the world’s highest-rated and most-reviewed teeth whitening brand, rated 4.5 out of 5 on Trustpilot across 8,500+ reviews, and trusted by over 2 million customers across the UK, US and EU.
The Powder is also clinically tested, carries the Dermatest® 5-Star Seal of Approval, with 65% of users noticing improvements within 14 days and 35% reporting visible results within 7 days. Individual factors like enamel thickness, diet, and the depth of existing staining can all influence the pace and extent of results.
Thank you again for taking the time to share your experience.

Hi Glenn,
We’re sorry to hear about the delay with your order. 99% of our orders are delivered within 1 to 2 days, so if yours hasn’t arrived, something has clearly gone wrong with the courier, and we understand how frustrating that must be.
We reply to every customer who contacts us, so we’d like to find out why you haven’t had a response from us. We haven’t been able to match your name to an order on our side, so please email us at help@mysweetsmile.com with your order number and we’ll sort this out for you, including arranging a replacement if needed under our Delivery Promise.

Hi Lee,
Sorry your order arrived empty. That is not acceptable, and the photos you sent make it clear what happened.
Your email was answered by a member of our team, not by anything automated, and we offered to send a replacement of your full order of 3 x MySweetSmile Teeth Whitening Powder at no extra cost. That offer was made twice, and it is still open today.
You have not been ignored, and the replacement is yours whenever you want it.

Hi Paul,
Thank you for taking the time to leave this. Good to hear your order arrived quickly and that you are getting on well with it so far.
You are early on, so there is more to come. Daily use across the first 14 days is where the biggest change builds, then twice a week to maintain. The full routine is here if you need it: https://mysweetsmile.com/pages/instructions.

Absolutely will never order from here…
Absolutely will never order from here again. Ordered a product on 5th October and it got sent out for delivery, there was no attempt of delivery at all (cameras all-round property). Got an email to say attempted and returned to the supplier. Contacted them and they apologised and said we will send another out today. That was the 6th October. I received no emails with tracking or confirmation and no contact from then on. Today 18th October I still have no order. Contacted them again and they told me it was sent out on the 15th and returned to them. No explanation why! They just say support will contact you in 1-2 working days. So I can't get a refund and im still without the product. Poor poor service.

Hi Amanda,
To set out what happened. Your first order was returned to us because the house number was missing from the delivery address at checkout, which your order confirmation will show.
Your replacement was delivered by DPD at 15:16 on Saturday 10 October, with proof of delivery held by DPD. You then contacted us to say you had not received it, and we refunded you.
If anything above does not match what you have, email us at help@mysweetsmile.com and we will go through it with you.
