Sarah Mitchell
I used to cover my mouth every time I laughed. I dreaded photos—always the one doing the closed-lip smile while everyone else beamed. After just ONE use of Teethfy, I caught myself grinning in the mirror. Now I'm the one suggesting group photos. My only regret? Not finding these sooner.

DENTIST-APPROVED
Created with dental pros for people who've been told "your teeth are too sensitive."
OVER 9/10 DENTISTS RECOMMEND 
I've spent 15 years watching patients struggle with whitening—the sensitivity, the damage, the disappointment. Finally, there's something I can recommend with confidence. This formula actually works WITHOUT the pain. It's what my own family uses.
Why settling for yellow teeth isn't worth it
Studies show people with whiter teeth are perceived as more successful, more attractive, and more confident. You don't have to live with stains from coffee, wine, or just... life. In 30 minutes a day, you could be one of those people who lights up a room with their smile.
What our customers say on
I'm a smiler now
Never thought I'd describe myself as someone who smiles a lot. After these strips? I literally can't stop. My face hurts from smiling 😂
Sarah Jenkins
Sensitive teeth? This is it.
If you've tried everything and given up, try this one more time. I promise it's different. No pain, actual results. Finally.
Michael Brown
Undid 5 years of coffee damage
I drink an embarrassing amount of coffee. My teeth showed it. After 9 treatments, they look like they did in college. Wild.
Emily Wilson
Better than my $600 dental treatment
Spent $600 at the dentist last year. This $35 box did more. I feel scammed by that dentist now tbh.
David Lee
My dentist was shocked
She asked what I did. Showed her the box. She was genuinely surprised something this gentle worked so well. Now she recommends it!

I actually smile in photos now
For YEARS I've been "the one who doesn't show teeth" in every photo. I was so self-conscious. I tried expensive treatments but they killed my sensitive teeth. Teethfy was different—no pain, and after a week my husband said "your smile looks different... brighter." That was all I needed to hear.

Saved $400 and got better results
My dentist quoted me $500 for whitening. I thought I had no choice—yellow teeth were ruining my dating life. Then I found Teethfy. Same results (honestly, better) for a fraction of the cost. Now I actually look forward to first dates.

Finally confident in meetings
I'm a manager and I used to hate speaking up in meetings—I was always conscious of my stained teeth. Now I lead presentations and actually SMILE while doing it. Such a small change, such a huge difference in how I carry myself.

Wife noticed immediately
I'd been embarrassed about my coffee-stained teeth for years. After just one treatment, my wife asked "did you do something to your teeth?" That's when I knew it was working. Zero sensitivity—and I usually can't even handle cold water!

STOP PAYING DENTIST PRICES FOR DENTIST RESULTS.
The average in-office whitening costs $500-$1,000. And guess what? You still leave in pain. Teethfy gives you the same (often better) results for under $35—from your couch, on your schedule, with zero sensitivity. The only question: why haven't you tried this yet?
This is what transformation looks like
Real customers. Real results. No Photoshop.

STILL DEALING WITH PAINFUL STRIPS?
THERE'S A BETTER WAY.
Most whitening strips are designed by people who've never had sensitive teeth. They blast your enamel with harsh peroxide, leaving you in pain (and sometimes, barely whiter). We built something for real people with real sensitivity.
- Actually works for sensitive teeth
- No painful "zing" feeling
- Doesn't damage enamel
- Results from day one
- Made by people who get it
OTHER BRANDS
- Pain you "just deal with"
- Sensitivity for hours after
- Weakens your enamel over time
- Takes weeks to see anything
- Designed for "normal" teeth only
The numbers don't lie—this actually works
0

dentists recommend our formula for patients who've given up on whitening
*Based on 2,400+ verified customer surveys over the past 12 months.
WHAT IF IT DOESN'T WORK FOR ME?
Then you pay nothing. Seriously. Try Teethfy for 30 days. If you don't see whiter teeth, if you're not smiling more confidently, if it's just not for you—email us and we'll refund every penny. No return needed. No questions asked. We're THAT confident you'll love your new smile.

I stopped declining photo invites
I used to dread when someone pulled out their phone for a group photo. Now? I jump in. My teeth aren't perfect but they're SO much brighter. That's all I needed.

Finally something that doesn't hurt
I've literally thrown out 3 different whitening products because the pain was unbearable. This one? Nothing. Zero. And it actually works better than all of them.

Coworkers keep asking about my teeth
Someone at work asked if I got veneers 😂 Nope, just these strips. Coffee stains from 10+ years of 3-cups-a-day are finally gone.

Still have questions? We've got answers.
Yes! In fact, we MADE this for people with sensitive teeth. Most of our customers had given up on whitening because everything else hurt. Our mineral salt and coconut oil formula is the gentlest on the market—95% of users report zero sensitivity.
Most people see a noticeable difference after their very first treatment. Full results typically come after completing all 9 treatments over 2-3 weeks. But that first "wow, my teeth look different" moment? Usually today.
Coffee drinkers are literally our biggest fan base. Our formula is specifically designed to break down coffee, tea, red wine, and smoking stains—even years of buildup. You don't have to give up your morning cup.
Those strips use harsh peroxide that bleaches teeth at the cost of sensitivity and enamel damage. We use a patented mineral salt and coconut oil formula that lifts stains gently. Same results, zero pain, healthier teeth.
With normal eating and drinking habits, most customers maintain their results for 4-6 months. Many use a single maintenance strip once a week to keep their smile bright year-round.
Then you pay nothing. Our 30-day guarantee means you can try it completely risk-free. If you don't see whiter teeth, email us for a full refund. No return needed. We mean it.
Just 30 minutes. Apply the strips, binge an episode of something, remove them. That's it. Most people do it while getting ready in the morning or winding down at night.
