Teeth Whitening Strips

Before and after photo, really impressed. I would 💯 recommend 👌. I left the strips on for 30 minutes.

These are really effective! I've been using them for six days and you can really see the difference. So pleased!

Joanne S. 5/5 June 6, 2025

As a 61 year old I had little hope of any improvement. What a wonderful surprise! After using for just a few days I could see a definite improvement. So happy and shall continue to use forever!

I am so happy! Although my teeth are in no way perfect now the difference for just one box of strips is incredible. Gleam has quickly helped removed a ton of brushing-resistant tea stains on my teeth which were really ageing me and just generally making me feel gross. I’ve never used strips before but these were easy to get used to, I put them on before my drive to work and take them off when I arrive. Definitely recommend

Kajsa 5/5 June 10, 2024

Very happy with my results!! My teeth were so yellow and stained before from drinking coffee everyday but I have seen amazing results and I haven’t even finished the course yet

I've just ordered a second box as they do actually work! Yes there is some light variation in the pics but I've been happy with these strips as nothing else similar has worked for me. X

Emm R. 5/5 September 22, 2023

After using the strips daily for 6 days I am very happy with these results. The strips come in lovely packaging and also taste fairly nice (almost like having a mint in your mouth LOL). Overall very happy and will be buying more….

Corina M. 5/5 July 12, 2023

Here are my results after two 30 minute sessions. Overall the strips were easy to use, there was no sensitivity and the results have been pretty good. I will be recommending these!

Aleasheia S. 5/5 July 12, 2023

Here are my results after 4 sessions. So far I am very happy as there has also been no sensitivity at all! I have already recommended these strips to my family and friends!

Jason W. 5/5 June 29, 2023

The strips have been working well for me, very happy I tried these out! I will certainly be buying these again

Oliver H. 5/5 June 13, 2023

Here are my teeth after using the Gleam teeth whitening strips for 2 weeks. My teeth were a little stained from all the coffee I have drank over the years however these strips seem to have really lifted the stains. I have to say that I am pleasantly surprised by the significant results I have managed to achieve! All without any sensitivity either, 5 stars.

Dani W. 5/5 June 9, 2023

Very happy with my results so far! Ordered these on Thursday and this is my results after 5 uses. I was really worried about sensitivity but I have had no issues at all so far, will be ordering more.

Neil B. 5/5 June 8, 2023

Absolutely love these! I was definitely fairly skeptical before purchasing these but I am so happy I tried them out. They are really easy to use and there is no sensitivity at all. I’ve already recommended them to friends and family! X

Sandra W. 5/5 June 8, 2023

I am really enjoying using these strips! They work well, no sensitivity and the packaging is lovely. 5 stars from me.

Jonathon N. 5/5 June 8, 2023

Results after 4 sessions of the strips, I can definitely see a significant difference… Very happy!

Alex W. 5/5 June 8, 2023

I had my doubts but these strips have worked really well! These are my results after 2 sessions. No sensitivity either x

Alicia O. 5/5 May 6, 2023

Easy to use with instant results. I have just used my 5th strip and my teeth are at least 4/5 shades whiter. What a difference having a white smile makes!!

Steve T. 5/5 February 9, 2023

Results after 5 sessions. The results are great but what I like about these is how easy they are to use! Would 100% recommend

Lewis D. 5/5 January 10, 2023

A serious game changer! Love that it doesn’t leave my teeth feeling super sensitive afterwards too! 10/10 product and would defo recommend!

Mia C. 5/5 December 16, 2022

I absolutely love these strips! I could see a huge difference in my teeth over the past few days. My teeth have always been something I have been self conscious of but after using these strips it it has made me feel so much better about my teeth. Thank you so much Gleam!

Sasha F. 5/5 December 15, 2022

The strips are working great for me so far! Smiles all round x

Olivia O. 5/5 December 15, 2022

Absolutely insane! Gleam is the only teeth whitening company that I've actually seen results from and are so genuine! The customer service team were so kind and super helpful and provided me with all the information I was looking for. Have recommended to my fam and friends

Ellie M. 5/5 November 22, 2022

After 4 sessions I am super impressed. Really simple to use, no mess at all and has really helped with my confidence! Also the packaging is lovely.

Lisa N. 5/5 November 21, 2022

Really happy with the effects after one use. I am excited to finish the pack, no sensitivity either.

Jenny D. 5/5 November 16, 2022

I’ve got naturally quite yellow-toned teeth so wasn’t sure how much difference strips could realistically make. They haven’t turned them paper white obviously, but they’re significantly brighter. I’d say around 3 shades for me.

Poppy T. 5/5 August 24, 2026

Really happy with my purchase. My smile looks fresher and I feel more confident showing my teeth in photos now.

Dylan G. 5/5 August 24, 2026

Pleasantly surprised by how comfortable they are. I thought having strips on my teeth would annoy me but after a few minutes I basically forget about them.

Rhys M. 5/5 August 24, 2026

Used these in the run up to my birthday and loved the result. My teeth looked noticeably whiter without that fake glowing-white look.

Callum M. 5/5 August 24, 2026

Good results but I’d say consistency is important. I didn’t notice loads from one or two applications, but once I’d used them regularly the difference became obvious.

Stewart F. 5/5 August 24, 2026

They’re really easy to use and I didn’t have any sensitivity which was good, but the results just weren’t as noticeable as I was hoping for. My teeth do look a little brighter, just not a huge difference for me personally.

Lewis F. 1/5 August 24, 2026

I don’t normally leave reviews but I’m genuinely impressed with these. I’ve wasted money on whitening toothpastes for years and never really noticed anything. With these I can actually see a difference.

Ibrahim R. 5/5 August 24, 2026

5 stars from me. No sensitivity, easy application and probably 2-3 shades whiter.

Reuben C. 5/5 August 24, 2026

Bought these mainly for my two front teeth because they always looked slightly more yellow than the others. The colour looks much more even now.

Daniel O. 5/5 August 24, 2026

I’ve been using them before bed and they’re honestly so convenient. I wasn’t expecting such a noticeable result from something this simple.

Zain A. 5/5 August 24, 2026

Easy to use and noticed results within a few applications.

Arjun P. 4/5 August 24, 2026

I kept seeing Gleam everywhere and eventually gave in 😂 Glad I did. Definitely one of the better whitening products I’ve tried.

Muhammad K. 5/5 August 24, 2026

Very happy. My teeth look brighter and I haven’t had that horrible sensitivity I’ve experienced with other whiteners.

Archie D. 5/5 August 24, 2026

Had some staining from years of coffee and these have definitely helped. Not completely gone but significantly better.

Theo J. 5/5 August 24, 2026

I like that whitening my teeth doesn’t have to be a whole event anymore. These take basically no effort and I can use them while doing stuff around the house.
