5 reasons your child's pillow is deforming their face

In short:

My son slept with his mouth open every night. I thought it was sweet. I had no idea it was slowly reshaping his face, until a dentist showed me what was coming.

Here is what I found out. And why today over 50,000 families don't want any other pillow.

Every night, a normal pillow takes your child's air away

A normal pillow was never designed for a small child's neck. Too high, too soft. It bends the neck and pushes the chin towards the chest.

In this position the airways narrow. The nose is no longer enough. So the body does the only thing left to keep breathing: it opens the mouth. Every night, for 8-11 hours straight, for years.

That is where it all starts. Not with your child. With an object in their bed that nobody has ever questioned.

An open mouth shapes the whole face in the wrong direction

When the mouth stays open, the tongue slips away from its natural place against the palate. And that changes everything.

The tongue is the living mould of the face. It pushes against the palate and guides the jaw to grow forwards and wide.

Take that support away from the tongue for 8 hours a night and the palate becomes narrow and grows downwards instead of forwards. The face gets longer, the chin recedes, the teeth crowd. Dentists call it long face syndrome.

And it is happening right now, in a window of time that will never open again

A child's facial bones are soft and mouldable. Like clay that has not hardened yet. And that is exactly why mouth breathing deforms them so quickly.

60% of facial development is decided before age 6. Between 9 and 13 the window closes. Then the clay hardens. Whatever has taken shape stays that way.

Every night on the wrong pillow, the problem takes root a little deeper.

What parents try instead

Mouth tape. Expressly not recommended for children.

Myofunctional therapy. Costs a fortune and takes months.

Palate expansion. A procedure, not a pillow.

None of these touches the object your child rests their head on nine hours a night.

The wrong pillow stays there. And keeps pushing.

The Arcastral kids pillow puts the head back in the right position

Developed together with dentists who specialise in airways. The Arcastral kids pillow keeps the head tilted at 15° thanks to a 3-zone structure. And the whole chain reverses:

No more snoring at night

Neck and spine align at an ergonomic 15° angle

Protects the face your child was born with

Arcastral does not correct your child. It gives back the right conditions.

Night after night the jaw widens, the chin defines, the face grows in the right direction. On its own.

€34 today, or the orthodontist tomorrow

The maths is simple.

Do nothing: fixed braces for the top and bottom teeth, year after year, for the whole length of treatment, and it adds up. If jaw surgery is needed too, the bill climbs even higher. Not to mention a face no one can give back.

Act: a pillow from €34.

Yes Claire! We got it 3 weeks ago. My son (5) has slept with his mouth closed ever since and the pillowcase is finally dry in the morning. At the last check-up the orthodontist asked us straight away what we had changed.

We got the 3-9 years and it's perfect. If in doubt take the bigger one, it says so on the page too

At first we got the wrong pillowcase, but customer service answered the same day and sent the right one. The pillow itself is great, my son won't hear of any other
