Can cotton pillowcases make dry mouth worse during teeth whitening?

Yes. Wearing a whitening tray overnight naturally leads to sleeping with your mouth slightly open, which dries out the surrounding skin. A cotton pillowcase wicks away what little moisture remains and its rough texture rubs against the tray's edge on your cheek. A perfectly smooth 100% mulberry silk pillowcase (no embroidery), like Silkhouse's, doesn't pull moisture from your skin and reduces friction at the tray's edge, for a more comfortable whitening routine.

The Cotton Trap When Wearing a Whitening Tray

Many teeth whitening protocols involve wearing a tray overnight, which naturally leads to sleeping with your mouth slightly open. The result is dry, dehydrated skin around the lips and cheeks by morning. Cotton, a highly absorbent fiber, wicks away what little moisture remains on your skin, and its rough texture rubs against the tray's edge where it rests on your cheek, compounding the irritation.

The Hydration Solution: 22 Momme Silk

Mulberry silk has a smooth, non-absorbent protein structure that doesn't pull moisture from your skin the way cotton does. Its slippery surface also glides against the tray's edge instead of catching on it, reducing friction on skin already stressed by mouth-breathing. The result: less morning dryness and irritation around the mouth.

        "Beware of false good ideas: a pillowcase for nights spent wearing a dental tray must be perfectly smooth. Avoid embroidery and sewn-on logos — those synthetic threads add extra friction exactly where your skin is already compromised. The minimalist design of Silkhouse silk isn't an aesthetic choice, it's a comfort requirement."
