Nathan & Sons promotes Underbrush, a gum containing nano-hydroxyapatite to support tooth remineralization. The brand encourages customers to invest in their smile beyond morning and nighttime routines. Underbrush is positioned as a way to help prevent cavities and sensitivity throughout the day.

You brush twice a day.

(And if you're reading this, we're going to assume you actually floss too.)

Every year, most Americans spend money on:

Toothbrushes, floss, whitening products, braces or aligners

That's a good thing.

You care about your teeth.

You want to do the right thing for your smile.

But even if you're doing everything "right"...

Sometimes cavities still happen.

Sometimes sensitivity shows up.

Sometimes you end up in the dentist's chair hearing words you'd rather not hear.

TRY SOMETHING BETTER

What if there was something you could do during the other 23 hours and 56 minutes of the day?

That's where Underbrush comes in.

While most gum is basically flavored plastic, Underbrush contains nano-hydroxyapatite, the same mineral your enamel is made from.

In simple terms?

It helps support remineralization.

That means helping your teeth stay strong and supporting the repair of tiny everyday wear and tear before it becomes a bigger problem.

Underbrush by Nathan & Sons

You already invest in your smile every morning.

You already invest in it every night.

Why not invest in it all day long?
