Safest Teeth Whiteners
The safest ways to whiten your teeth explained
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.
Additionally, Hismile has an on-site facility (Hismile Research Centre) for product testing and formulation. This allows them to work with leading dentists and product experts to shape the future of teeth whitening.
Hismile sells a few different oral care products, including a whitening kit, strips, toothpaste, and mouthwash.
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
However, Hismile’s at-home teeth whitening treatment claims to be just as effective as peroxide without the unpleasant side effects. Peroxide as a bleaching agent 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 takes a total of 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:
Some customers see results after one to 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. This takes about a week (six treatments) if you do them back-to-back.
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.
Based on customer reviews, Hismile seems to be a relatively effective whitening product. Many customers mention instant results, while others don’t see results until after six treatments.
There are also some negative reviews (as with any product). Some customers say the products don’t work at all. However, this could be due to deep staining, which often requires professional whitening in a dental office.
Based on our research and personal testing, Hismile’s products do work in most cases. Keep reading below to learn more about the effectiveness of Hismile whitening.
I personally tested Hismile’s PAP+ Teeth Whitening Kit™. The main benefit of this kit is that it is very easy to use. It also doesn’t irritate your gums, cheeks, or tongue.
With other whitening kits, I’ve noticed they can cause irritation during and after treatment. This is especially true if the product has a high concentration of peroxide. But since Hismile doesn’t use peroxide, this wasn’t an issue.
Another benefit of Hismile is the quick treatment time. You only have to use the kit for 10 minutes a day. Other leading brands typically require 30 to 45 minutes of whitening per session. I’ve found this to be inconvenient and it often makes the process messier.
Lastly, in terms of results, I noticed minor changes in tooth color after just one 10-minute session. The changes weren’t drastic, but they were noticeable. I also experienced zero sensitivity after the first use.
Note: My teeth were already fairly white to begin with. I don’t have deep-set tooth discoloration.
If you are looking for a sensitivity-free treatment with quick results, Hismile is worth checking out.
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 just 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 that toothpastes containing potassium citrate are effective in reducing dentin hypersensitivity.11
Based on our research, Hismile’s PAP+ whitening formula seems to be safe. Most customers are satisfied with their whitening results and don’t experience adverse reactions.
Note: PAP is a newer ingredient that can be found in select whitening products. It has not been extensively studied. Because of this, some dental experts advise against it.12
For example, Dr. Mark Burhenne, DDS ‘recommends waiting for further studies to be conducted on PAP before jumping on the bandwagon.’ He says overexposure to hydrogen peroxide and PAP can increase tooth sensitivity.12 But this has not been proven.
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:
