Safest Teeth Whiteners
The safest ways to whiten your teeth explained
In this article
This is an in-depth review of Hismile teeth whitening products. In this article, we’ll cover:
Hismile is an Australian-based brand of oral care products, specifically peroxide-free whitening. The products are widely used in the UK but are growing in popularity in other countries.
Hismile uses a proprietary PAP+ formula to whiten teeth. The hero ingredient, phthalimido peroxy caproic acid (PAP), claims to whiten teeth quickly and effectively without irritation or sensitivity.8
The Hismile formula also has other supporting ingredients that enhance the health of your teeth. They include hydroxyapatite and potassium citrate.
I tested Hismile’s claims and ordered a teeth whitening kit for myself. This article covers my experience, the history of Hismile, and more.
I saw whitening results after my first 10-minute session with Hismile’s product. I used the Hismile Teeth Whitening Kit a second time, and the results improved. The images below are the before and after of my smile.
Following the instructions on the packaging, I brushed my teeth thoroughly beforehand. Then, I removed the mouth tray to connect to the LED device.
Wearing the device for just 10 minutes was notably more comfortable than other whitening processes. Plus, 10 minutes is on the shorter end of at-home treatment times.
Once the blue light switched off automatically, I rinsed the mouth tray and put everything back into its allotted space in the box.
As a person with sensitive teeth, I felt apprehensive about integrating a new product into my routine. Thankfully, the Hismile Teeth Whitening Kit did not trigger any sensitivity, as promised.
I was most surprised by how easy it was to use. The whitening gel stays neatly within the trays. Not having to set a timer for the 10 minutes is also very helpful.
Replaceable batteries and well-made components make the Hismile Teeth Whitening Kit a worthwhile investment for long-term whitening. Additional whitening gels can be purchased on Hismile’s site.
The included shade guide also makes it simple to track visible improvement in your teeth’s whiteness over time. Simply find the shade that matches your natural state.
Before trying the Hismile Teeth Whitening Kit, I had some yellowing toward my teeth' edges. This disappeared after two uses and revealed a more even and bright smile.
If I used the whitening kit more than twice, I’m confident my smile would have gotten even whiter. Hismile guarantees results up to eight shades whiter after six 10-minute sessions.
This product is a fantastic way to whiten your teeth at home, thanks to its affordability and ease of use. The immediate results make it a great addition to any pre-event routine.
I recommend trying this whitening kit if you have sensitive teeth or are looking for an effective and affordable peroxide-free whitening experience.
Hismile launched its first teeth whitening kit in 2014. They sent kits to hundreds of people to try out during this time — from video bloggers to celebrities like Kylie Jenner.
The overall verdict was positive. Now, Hismile has a global community of over 3 million customers.
Hismile’s whitening formula is 100% peroxide-free. Peroxide is the main active ingredient in most whitening products. It has been extensively studied as an effective whitening agent.1, 2, 3
Hismile’s at-home teeth whitening treatment claims to be just as effective as peroxide without the unpleasant side effects. Peroxide can cause sensitivity, gum irritation, and the demineralization of teeth.1, 4, 5
Hismile's teeth whitening kit uses three powerful, enamel-safe ingredients to provide instant results without any sensitivity:
The Hismile PAP+ Teeth Whitening Kit is very easy to use, especially compared to similar products on the market. The process requires 10 minutes a day (vs. up to 45 minutes for other brands).
The kit includes an LED device with a built-in timer, a universal mouth tray, six whitening pods, and a shade guide.
To use the kit, follow these simple steps:
I saw results after two treatments. Results vary depending on your level of tooth discoloration.
Hismile’s whitening kit comes with six pods. One full pod is used per treatment.
You’ll likely notice the full benefits after you complete the full treatment course. If you do them back-to-back, this takes about a week (six treatments).
Hismile claims the whitening results should last between two weeks and three months.
How long your teeth stay white depends on lifestyle and diet habits. For example, if you drink a lot of coffee, the results won’t last as long. You’ll need to whiten more consistently.
Other staining foods include dark-colored berries, red wine, soda, curry powder, and tomato sauce. Cigarette smoke also discolors teeth.
Hismile products are peroxide-free for a few reasons:
Hismile’s initial goal was to develop a whitening formula that provides peroxide-level whitening without the side effects. This is how they discovered PAP and created the PAP+ formulation.
According to Hismile, the PAP+ formula combines expert-level whitening with fast and effective results. Unlike peroxide, PAP doesn’t release free radicals or dehydrate your teeth. This means that the discoloration molecules are broken down safely, without the risk of sensitivity, damage, or irritation.8
PAP is a highly reactive whitening agent that lifts stains by targeting internal and external discoloration. Due to its potency, it can whiten teeth after one to two treatments. Results vary.
An independent study found that PAP had immediate whitening effects after a single-use treatment.10
The PAP+ formula also contains hydroxyapatite (nHAp). Some research shows that hydroxyapatite is superior to conventional fluoride for cavity prevention.9 nHa also mimics your natural tooth enamel (provides protection) and replaces lost minerals.
Lastly, the PAP+ formulation contains the active ingredient potassium citrate. This ingredient helps prevent and reduce sensitivity. One study found toothpastes containing potassium citrate are effective in reducing dentin hypersensitivity.11
“PAP is used as a bleaching activator for teeth whitening by whitening the discolored molecules in your teeth,” shares Dr. Roshan Parikh, CDO at dntl bar.
Besides PAP, Hismile’s Teeth Whitening kit uses nHAp and potassium citrate. “The inclusion of a nano-particle apatite (nano-hydroxyapatite) and potassium citrate offer additional benefits to the teeth during the whitening process, such as improved enamel structure and the reduction of pre-existing tooth sensitivity,” Dr. Parikh shares.
According to Elizabeth Graves, a registered dental hygienist, "The ingredient PAP isn't more widely used in whitening products because it is relatively new to the dental industry. Some dental professionals and most of the general public have not even heard of it before.”
She shares, "with the promising research about its effectiveness and safety, PAP will surely be replacing hydrogen peroxide in whitening treatments."
The Hismile PAP+ Teeth Whitening Kit is the brand’s #1 bestseller. It is the first product they created in 2014.
Since then, they have developed more oral care and whitening products. Here is a short overview:
