At Home Teeth Whitening Review + Giveaway! | She Sweats Diamonds

When I was growing up, I didn’t smile a lot. I was very insecure and shy so imagine when the dentist told my mom I needed braces. Oh joy, let’s add braces too.

But my teeth were really bad. Case in point (zoom in to the photo on the left):

I just wanted to feel confident in myself so I agreed. I wore braces from 6th grade to spring of sophomore year in high school. That’s a longgg time to be wearing braces. Maybe that’s why I dislike going to the dentist so much. Anyway, after I took my braces off, I started smiling again. A lot. Look at me cheesin’ in my drill team pictures above, haha! 

Then came the college years. During my time in college, I drank a lot of coffee to pull all-nighters in between volunteering and leading events for an honor society I was a part of. Obviously, my love of bean water resulted in having coffee-stained teeth so I went to Target and tried some at home whitening with some teeth whitening strips. I liked my results, but hated when I ended up with incredibly sensitive teeth so I stopped. The pain reminded me of my first week of wearing braces; it was that bad.

I was just talking to my bestie earlier this summer about how it’s been years since I’ve whitened my teeth and that I was thinking about doing it again.

Well, the beauty gods must’ve heard our conversation and smiled down on me (see what I did there?).  

When Smile Brilliant reached out to me for a collaboration about a week after my conversation with my best friend, I knew our partnership was meant to happen.

For those of you who have never tried at-home teeth whitening, I happily agreed to test out their product to give you an honest review. 

Before I give you the details, here’s the low down: Smile Brilliant sends you a kit containing everything you need to create custom-fitted, professional whitening trays of your own. You make impressions of your teeth, send them back to Smile Brilliant in an envelope they provide. Their dental lab creates your whitening trays and sends them back.

Does at-home teeth whitening work? Is it easy peasy? What about teeth whitening for sensitive teeth?

I know. You’ve got lots of questions. No worries. Here’s my teeth whitening review to answer your questions:

How to Get Your Teeth Impressions

Creating your custom-fitted teeth whitening trays is a lot easier than I thought. All you do is mix one of the catalyst pastes with one of the base pastes to form impression material. Definitely made me miss playing with Play Dough, ha! Next, spread it out evenly on the blue tray. After that, take the tray and push it up firmly into your teeth. Make sure to use your fingers to push the tray up on the back parts of your teeth as well. Don’t wiggle the tray back and forth. Hold it there for about two minutes, remove it and set that tray aside. It’s important that you don’t remove the impression material and leave it in the tray.

Repeat with the other tray for your bottom teeth. After you finish with both trays, let them sit for 30 minutes to harden. After time is up, rinse the trays, let them dry completely, pop them into the envelope Smile Brilliant provides and ship it back to them so they can make your final custom whitening trays!

Teeth Whitening Process

Smile Brilliant recommends whitening between 45 minutes to 3 hours depending on your tooth sensitivity. They also recommend to whiten your teeth before bed so the desensitizing gel has time to absorb into your teeth and you’re not introducing any food/drink that could cause staining.

Here’s what you do when you get your custom fitted teeth trays back:

  1. Brush your teeth with water. Do not use toothpaste because the fluoride slows down the whitening process.
  2. Put a thin strip of the whitening gel on your trays. Make sure your teeth are as dry as possible and pop them in. Whiten for 45 minutes to 3 hours. I started with 30 minutes the first time because I leery on how sensitive my teeth would be so I worked my way up to 45 minutes then to an hour.
  3. Take your trays out (don’t forget to wash and dry them) and brush your teeth with toothpaste as normal.
  4. Next, do a desensitizing gel session for 15-30 minutes. All I can say is thank God for desensitizing gel!!!
  5. Remove trays (don’t forget to wash and dry them), but don’t rinse or brush your teeth for 20 minutes, just spit. You want to leave a thin layer of desensitizing gel to coat your teeth. Then head to bed! 


I tried this kit out on and off for about two months to feel the affects. There were some weeks that I whitened every two days because I got so busy, but I’m happy to say that my experience was great! The desensitizing gel Smile Brilliant offers definitely inhibited sensitivity and protected my teeth against re-staining while I was whitening. As you can see, the upper part of my teeth are whiter. Even though you can’t see my bottom teeth, they’re whiter too! 

Unlike the strips I used in college, which only was able to cover the front areas of my teeth, I love how my trays covered all of my teeth to make sure I got even results.

When I took a poll on Facebook and asked my friends what was important to them about teeth whitening, sensitive teeth, cost of teeth whitening and convenience were their concerns. 

I understood their answers because I ended up having pain and sensitive teeth from what I thought was an affordable teeth whitening kit from Target years ago.

All this to say, I love Smile Brilliant! Unlike the whitening strips I tried, their teeth whitening trays are so easy. I truly love my custom fitted teeth whitening trays! Put the whitening gel in, pop it on, set a timer and go about your business. 

Sure, I could go and get professional teeth whitening done, but I don’t have time since my schedule is always packed. That and I hate going to the dentist. So if a busy person like me can do it, so can you. 

If you’re still leery about teeth whitening in general, I understand. I firmly believe in educating yourself before you make a decision so here are some teeth whitening factsFAQs along with foods that are good for your teeth, pros and cons of teeth whitening systems, including LED teeth whitening and what you need to know before buying teeth whitening kits.                          
As a girl who hates going to the dentist, I highly recommend you give Smile Brilliant a chance, which is why, wait for it…
