HANIC WHITELABO Co., Ltd. will launch a new product for those who use mouthpieces during sleep, 'Shimac Sleeping Care for Mouthpieces,' from its 'Shimac' oral care series that creates a protective film on teeth. The product will be available on the official website starting May 28, 2026.

Block biofilm while you sleep! 'Shimac Sleeping Care for Mouthpieces'

In recent years, an increasing number of people are wearing mouthpieces (night guards) during sleep as a measure against teeth grinding and clenching.

Saliva secretion tends to decrease during sleep, and wearing a mouthpiece can create a stuffy environment for the tooth surface, making oral stickiness and discomfort upon waking a more significant concern for many.

'Shimac Sleeping Care for Mouthpieces' is a new bedtime oral care habit that creates a transparent film barrier on the tooth surface before biofilm, one of the causes of the stickiness formed by bacteria gathering on the teeth, can form.

By applying it to the tooth surface before sleep, it forms a smooth, sleek film that physically coats the teeth. This helps to condition the tooth surface environment during sleep and supports an environment where biofilm is less likely to form.

In the morning, you can simply brush it off with the film, making it a new oral care habit for while you sleep.
