Founding 50 · Phase 1 pilot study
Help us answer one question: do kids actually like brushing with toothpaste tablets?
We’re running a one-month study with 50 kids ages 4–12. Join with your child, or sponsor a spot for a family who needs one.
Ages 4+. Chew, then brush. Do not swallow whole. Adult supervision recommended.
Only 50 spots. Founding families get first access to the dispenser.
The study begins once all 50 spots are claimed, or on November 1, whichever comes first. Jars ship within 3–5 business days, so every family starts together.
The pilot is full. Thank you!
All 50 Founding spots are spoken for. Tell us what you’d like from our next batch and how to reach you, and you’ll be the first to know when we’re taking orders.
What families are saying
“It’s easy to chew, the flavor is incredible (speaking for both the kids and myself), and it creates the perfect, satisfying suds. 10/10 from us.”
“Dry until you add a little water, then it gets foamy, and it’s not messy at all.”
“The taste was excellent… a very easy transition, once I stopped reminding myself not to eat them like candy.”
Why this study
Brushing shouldn’t be a nightly battle. Sow Flow is built around behavior reinforcement: turning good intentions into lasting action, and empowering behavior rather than changing it.
So far, 74 customers have bought our tablets with zero advertising. Now we need real numbers: do kids keep using them, and do families come back for more?
We’re a small, independent company. Before we make our next big batch, we want to hear from real families: do kids like these, and would you buy them again? Your honest feedback decides what we make next.

FAQ
What ages?
4–12.
Fluoride?
No. Our tablets use nano-hydroxyapatite.
Allergies?
Check the ingredient list above (it includes sunflower oil). We screen for allergies with a short intake form before shipping.
How do kids use them?
Chew one tablet, wet the brush, brush, and spit. Adults should supervise younger kids.
Pets?
Keep tablets away from dogs. Xylitol is toxic to them.
Is shipping included?
Yes. Shipping anywhere in the U.S. is included in the $19.99 (plus sales tax).
Can I sign up more than one child?
Yes. Each child needs their own spot, and you can change the quantity in your cart.
When does it start?
Once all 50 spots are claimed. You’ll get an email with your ship date.
What if it doesn’t fill?
If we reach at least 30 kids by November 1, the study starts with everyone enrolled. If not, you can choose a full refund or keep your spot until we do.
What do I have to do?
Use the tablets, log brushing with a 10-second check-in each evening, and answer one quick question a week in our study app.
What happens to my data?
It’s used only for this study and never sold. We collect information from parents, never directly from children.
