We Tried 5 Popular Teeth Whiteners

June 20, 2022


Team LIY

What is it about having pearly white teeth that makes you feel more confident in your smile? Years of drinking coffee, tea, wine and more have definitely put some wear and tear on the color of our teeth, and we set out to fix that! There are so many at-home teeth whiteners on the market, from strips to toothpastes to LED kits that we wanted to put a few of the most popular ones to the test! Did we love ’em all? Nope, definitely not! But did we see some great results? Absolutely! Keep on reading to see which ones we liked and would recommend verses which ones we probably wouldn’t buy again!

PS. We love testing products to bring you the true winners here at LIY, which is why we’ve done a ton of product comparisons over the years! See them all here, from beauty and home to fashion and more!

The Results:

Steph’s Teeth Whitening Results

Crest 3D Professional Whitestrips

Steph Would Repurchase!

Crest Whitestrips caused no sensitivity issues and were easy to apply. I have used Crest in the past and had trouble with them sliding all over my teeth. This issue seems to be solved and they stick to my teeth perfectly until I take them off. In the pictures I don’t necessarily feel like I can tell a huge difference in whitening, but in person I feel like there has been an improvement. I would use these again in the future.”

Product Application: 20 strips, 20 days in a row, 30 minutes each

Katy’s Teeth Whitening Results

Lumineux Teeth Whitening Strips

Katy would NOT repurchase!

“Being pregnant, I wanted to try a more “natural/non toxic” solution to teeth whitening. I did feel like the Lumineux strips did the job and took away some stains, but not enough of a difference to make up for the goop and gel that sticks to your teeth after you take them off. That alone was enough to make me not want to purchase these again HA! Seriously, it was a lot.”

Application Process: 30 min // 7 times // use daily or as needed

Claire’s Teeth Whitening Results

Crest Whitening Emulsions Leave-on Teeth Whitening Kit

Claire would NOT repurchase!

“While the Crest Whitening Emulsions Leave On kit was easy to apply, I wasn’t 100% sure it’s actually staying on my teeth. It almost felt like after I applied it, it would just drip off and soak into my mouth (gross, I know). I think I would have liked it better, and might’ve had better results, if the product felt more secure to my teeth (ie. using a tray or strips of some sort!). Overall, it’s easy to use and I loved that I could apply it before bed and hit the hay! No sitting around waiting for 20 minutes like some other products I’ve used, no bulky tray involved, and no sensitivity. I truly felt like I noticed whiter teeth after the first use!!”

Product Application: Super easy to apply with no “down time”! Simply apply the product directly to your teeth using the application tool and let it soak in! I use it right before bed and wake up with whiter teeth! It feels a lot like applying toothpaste directly onto your teeth, without brushing it off. It’s an odd feeling, but I got used to it quickly!

Lisa’s Teeth Whitening Results

AuraGlow Teeth Whitening Kit

Lisa Would Repurchase!

“The AuraGlow Teeth Whitening Kit was a super easy application process and the kit comes with 2 pre-filled syringes to put in the mouth tray which is easy and not messy at all. No sensitivity issues when using product. I did not see a huge whitening difference after 10 days. Instructions didn’t say how soon you could start the next 10 day application process; so I am waiting a week and will start again in a couple days.”

Product Application: 10 day application, fill the tray with gel, place in mouth with light on for 30 minutes a day!

Lauren’s Teeth Whitening Results

iSmile Teeth Whitening Kit

Lauren Would NOT Repurchase

“The iSmile Teeth Whitening Kit works, there’s no doubt about it! My dental hygienist commented on how white my teeth were the other day! However, after using it for the full 7 days I was still never able to get the hang of putting the gel into the mouth piece and have it cover all my teeth. It suggested you could apply it to your teeth with a q-tip and then put it on, and I think I’d have better luck with that than putting the gel into the mouth piece as suggested! So for only 10 minutes a day for 7 days, you will notice a difference, but not feeling like I knew if I was actually getting the whitener onto my teeth or not made me not enjoy this actual process! I’d prefer to stick to the Crest Whitestrips I’ve used for years”

Product Application: Put gel in a tray and then place it in your mouth with the LED light on! Use it for 10 minutes a day for a minimum of 7 days!
