This enamel-safe essence gives you noticeably brighter teeth after each treatment while protecting your gums and enamel from being irritated, making it a great option for those with tooth and gum sensitivity.
The Key Ingredients of SmileFitPro™ Teeth Whitening Essence
Hydrogen peroxide
Hydrogen peroxide is a chemical compound with the formula H2O2. It is a powerful oxidizer and is commonly used as a bleaching agent, antiseptic, and disinfectant. In dentistry, hydrogen peroxide is used to whiten teeth, as it can break down organic molecules that cause tooth stains.
Sodium hydroxide
Sodium hydroxide, also known as caustic soda, is a highly caustic and reactive compound that is commonly used in the manufacturing of various products, such as pulp and paper, textiles, and soaps. It is also used in the production of some cosmetics and personal care products as a pH adjuster or neutralizer. In dentistry, it is used as an ingredient in some teeth whitening products.
PEG-400
PEG-400 is a water-soluble, biodegradable liquid commonly used in teeth whitening products. It helps the active ingredients penetrate and adhere to the enamel surface, allowing for a more effective and longer-lasting whitening effect. PEG-400 also acts as a lubricant, preventing any irritation or discomfort that may occur during the whitening process.
How to Use
1、Twist the pen to dispense serum.
2、Apply a thin layer to dry teeth.
3、Leave on and avoid eating or drinking for 30 minutes.
4、Use 1–2 times daily for best results.
SmileFitPro™ Teeth Whitening Essence – Frequently Asked Questions
Does it cause sensitivity?
No. SmileFitPro™ is formulated to be gentle on enamel and gums. Unlike many whitening products that can cause irritation or sharp sensitivity, ours is safe for daily use—even for those with existing sensitivity.
Can I use it on sensitive teeth?
Yes. SmileFitPro™ is safe and effective for people with sensitive teeth. It whitens without causing discomfort, making it ideal for long-term maintenance.
Is it safe for crowns, veneers, or bonding?
Yes. You can use SmileFitPro™ on dental work like crowns, veneers, composite bondings, and bridges. It won’t damage dental materials, though results may vary depending on the surface.
Does it work on Tetracycline stains?
Yes. While Tetracycline stains are deep and often difficult to treat, SmileFitPro™ helps reduce their appearance with consistent use. Results may take longer, but gradual improvement is possible.
How often should I use it?
We recommend once daily for most users. For faster or more intensive whitening, it can be used up to twice a day, depending on your sensitivity level.
When will I see results?
You may notice a temporary brightening effect immediately after application. With consistent daily use, most users report visibly whiter teeth within 5–10 days.
How long do the effects last?
You’ll experience an instant fresh, clean appearance that lasts up to 24 hours. Long-term improvements in tooth color build over 2–4 weeks of consistent use.
Can children or pregnant/breastfeeding individuals use it?
Yes. SmileFitPro™ contains no harsh chemicals, peroxide concentrations are within safe limits, and the formula is free from known toxic or hormone-disrupting ingredients. However, we always recommend consulting a healthcare provider for individual cases.
Do I need to reapply after eating or drinking?
Not required. SmileFitPro™ is effective with once-daily use, but it can be reapplied after meals, coffee, or wine if desired for touch-ups.
Can I use it with braces?
Yes. You can apply SmileFitPro™ around braces and brackets. It won’t interfere with orthodontic materials, but keep in mind that full whitening may be more visible after braces are removed.
Does it have a taste?
No. The formula is taste-free and scent-free. No bitter or chemical aftertaste.
Will it freshen my breath?
Yes. SmileFitPro™ helps neutralize oral pH and remove surface buildup that can contribute to halitosis. It leaves your mouth feeling clean and refreshed.
Will brushing remove the whitening effect?
No. Once the serum dries and bonds to the surface, brushing won’t wash away the effect. You can use it before or after brushing—it’s up to your routine.
Do I need to rinse it off?
Not necessarily. The formula dries within 5 minutes and leaves no visible residue. You may rinse after 5–10 minutes with water or mouthwash if preferred, but it’s not required.
Are the ingredients safe?
Absolutely. All SmileFitPro™ ingredients are dentist-approved, non-toxic, peroxide-based, and formulated with safety in mind. No long-term or short-term risks when used as directed.
Is SmileFitPro™ vegan and cruelty-free?
Yes. Our formula contains no animal-derived ingredients and is never tested on animals. We’re proudly cruelty-free and vegan-friendly.
Can I use it with LED whitening devices?
Yes. SmileFitPro™ is compatible with LED whitening lights and mouthpieces. Using it together can help accelerate results.
How should I store the product?
Store in a cool, dry place, away from direct sunlight. Keep the cap tightly sealed after each use to maintain freshness.

Rachel Mendez –
I travel a lot for work and this whitening pen has become a lifesaver. It’s small, lightweight, and I can use it discreetly in an airport bathroom if needed. I’ve noticed a real difference after two weeks—especially helpful after all those on-the-go coffees.
Jonathan Pierce –
After years of smoking, I was embarrassed by how dull my teeth looked. I gave this pen a shot and I’m honestly amazed. It’s easy to apply and didn’t irritate my gums. Now I smile in photos again.
Cynthia Lam –
I love how clean my mouth feels after using this. It doesn’t just whiten—it actually makes your whole mouth feel fresher. I’ve been using it nightly before bed, and my morning breath has improved too.
Edward Singh –
Good product but takes consistency. I didn’t see drastic results in the first few days, but by week two my teeth were noticeably brighter. It’s not magic, but it works if you stick with it.
Lauren Choi –
As someone with veneers, I was hesitant, but this was safe and gentle. It brightened the areas around my veneers beautifully, giving me an even, glowing smile. No sensitivity either!
Daniel Reyes –
The best part? No gross taste. I’ve tried other pens that left a weird aftertaste, but this one is practically tasteless and dries quickly. Super convenient for before date nights.
Amira Khan –
Good overall, but the twist dispenser takes some getting used to. Once I figured out how much to apply, it was smooth sailing. Just wish the packaging was a little more intuitive.
Olivia Brooks –
I’m a dental hygienist, and I tried this out of curiosity. It won me over. The formula feels safe, doesn’t over-dry the teeth, and it noticeably lifts daily coffee stains. Impressed.
Gabriel Thomas –
I wasn’t expecting much from a whitening pen but this one works! Within a few days, my teeth looked whiter and more even-toned. Perfect for last-minute touch-ups before work meetings.
Sophie Nilsen –
Super gentle. I have pretty sensitive enamel and usually avoid whitening products, but this gave me zero discomfort. Subtle change after 3 uses, but by the tenth it was a big difference.
Marcus T. Williams –
It’s okay, but you really have to use it daily. I skipped a few days and felt like the progress reversed a bit. Works best if you’re very consistent.
Tiffany Caldwell –
I’ve tried strips, trays, even the dentist gel—all left my teeth tingling. This pen is a game-changer. I can finally whiten pain-free and my smile has never looked better.
Brandon Kim –
I keep mine in my purse and use it after meals when I’m out. It’s practically invisible to use and doesn’t leave any residue. Great little product with real results.
Erika Doyle –
One star off because shipping took longer than expected. But the product itself is great. I’ve used it daily for a month and my teeth are definitely whiter.
Nathan Goldstein –
Big fan of the ingredients—no harsh bleach smell or artificial flavors. It goes on clear, dries fast, and does what it promises. Would absolutely repurchase.
Emily Vargas –
Noticed improvement on my tetracycline-stained molars. Nothing works miracles on those, but this pen has helped lift the yellow tones more than anything else I’ve tried.
Justin O’Neal –
Honestly, I didn’t expect to love this as much as I do. It’s sleek, easy to use, and gives a nice confidence boost. I’ll definitely keep this in my oral care routine.
