At Home Teeth Whitening: Does it Work?

This product was gifted to me to review by Smile Brilliant. As always, the experience, opinion review are completely my own.


Coffee Coffee Coffee!


There are few people on this planet I relate to more than Lorelei Gilmore. Her love for coffee, need to prove herself on her own, and quirky personality spoke to me once a week for years. And then again on Netflix on repeat for years.

But this post isn’t about my love for Lorelei. It’s about our shared love of coffee. The delicious black tar of the Gods. And while my heart, soul, and mental capacity to tolerate other humans all depend on it’s beautiful role in my life, my teeth do not appreciate it.

I still remember being a kid and on vacation with my dad and him asking me if I wanted a cup of coffee with my orange juice (like him). It was more creamer than coffee and I only took a few sips but the foundation had been laid. I’ve had a lifetime of coffee drinking for my teeth to combat with and whiting toothpastes just don’t cut it.

So, if you’ve ever been curious about teeth whitening, I hope you’ll take a few minutes to read through this post. It’s for you. I’ve tried it many times over the years and never had successful results. Whether it be from the dentist or OTC options, I hated them all. The ones from the dentist we super expensive and really uncomfortable. The over the counter ones have very minimal results, and there’s no way for them to be comfortable when they are a one size fits all. I also have sensitive teeth so both options ended up hurting. I was resigned to believe that teeth whitening was not for me.

That’s why when the crazy sweet and helpful team at Smile Brilliant reached out to me, I didn’t jump to try it out for quite a while. After a lot of questions and answers, I agreed to try the Sensitive Teeth Whitening System. The whole process was so easy thanks to their seamless process and because I did have such a great experience, I wanted to share it with you here.


Picking Your System

The first thing you need to do is go to the Smile Brilliant website and decide which package is right for you. They have two primary choices: The System for Non-Sensitive Teeth or The System for Sensitive Teeth. Pretty simple. Pick your door. From there you’ll be able to determine the level of program right for your specific needs.

If you have light staining, but don’t drink coffee or wine and have done whitening before then you’re good for the T3 System. However, since most people have staining from a lifetime of build-up from coffee, tea, wine, ect, I would recommend the T6-T9 systems. They are all the same product and all will use a custom molded tray, the difference will come in with amount of applications you will use.

The System for Sensitive Teeth that I used is the same basic concept, but typically is better for those with teeth sensitive to cold/hot, have had “aching” when doing teeth whitening in the past, had a history of childhood medication or smoking, ect. It allows for shorter application times and comes with a second type of application you’ll do after whitening to desensitize your teeth. I can attest to the fact that it really works. I was VERY skeptical because I have very sensitive teeth due to genetics and childhood meds combined with (as previously mentioned) an undying love for coffee.

First Things First (I’m the Realest)


Ignore the way my brain works. Before continuing this blog post I had to stop and do a Iggy Azalea mini dance party just because I thought of the lyrics. But I mean, come on people! Have you seen that music video? Summer 1995 Leslie came back in full swing.

Anyway, I digress. The real first things first, will be a package that arrives with your kit to make your impressions. I was a little nervous about messing this step up but it was really easy and they provide you one extra in event it doesn’t go right the first time. Just make sure that before your start the process of making the molds, you can see it all the way through.

It doesn’t take long but set aside 20-30 minutes with no distractions just to be safe. One you start, the activator in putty starts and you need to create your molds immediately after forming the dough. I’ve created a handy dandy photo guide of the process and you’ll get a comprehensive instruction sheet with your order as well.


After you’ve created your molds, you’ll use their return packaging to ship it back off to the company. They have a handy form to show you what your molds should like when done, so try to get it as close as possible to that. The company will examine them when they receive them to ensure they were done properly, and if they were, they will create your trays for you and mail them back.

The Whitening


This picture makes me laugh. Hello, Vanna White here, look at my trays. Full disclosure, I took these photos after I went through the majority of my applications, my teeth did not start out this white. I also usually use filters on my photos, but I opted not to edit these like I normally would so you could see the real results.

During the first fifteen minutes of my first application, I was like NOPE, don’t like this. I can feel it. I didn’t feel pain, but I just felt weird having something sitting in my mouth and not being able to talk. However, very quickly I almost completely forgot about it. And it was a really nice excuse to not get asked 10,000 a minutes by my kids. Oh no, sorry guys, mama can’t talk for the next hour. Come back later. Hello, mom win.

I did a few days with just desensitizing gel before starting the actual whitening at the recommendation of customer service since I have pretty bad sensitivity. If this is you too, you might want to get a couple extra syringes of the desensitizing gel just in case. After my first real session, and then quick session with the desensitizing gel, I was told I could put coconut oil on my gums to help sooth it but I wanted to see if would need it first. Turns out, I didn’t. My teeth were fine throughout the entire process and my results were amazing.

I would absolutely, 100% recommend this whitening company to everyone I know. And I really love that if you want to keep up the results you don’t have to keep buying the whole system. You have the option to buy the applications by themselves as well. I’ll be doing touch ups every few months just to ensure I keep them this white, because we all know I won’t be giving up my coffee. Ever.

*Disclosure - you HAVE to have the trays for this system to work, so the first time you purchase you’ll need to buy the whole system.

Have you ever done a whitening system before? I’d love to hear about your experience in the comments below!
