When it comes to products you use every night, especially something you put in your mouth, safety is the number one priority. At KULUN, we get questions about hygiene and materials all the time. Here is why material quality matters.
Why BPA-Free Matters
BPA (Bisphenol A) is an industrial chemical found in many plastics. Some studies suggest it can seep into food or beverages. Because a mouthpiece sits in your mouth for 7-8 hours a night, it is critical that it is free from harmful chemicals.
KULUN is 100% BPA-Free and Latex-Free. We use medical-grade EVA (Ethylene Vinyl Acetate), a material widely recognized for its safety, flexibility, and durability in oral appliances.
The "Boil-and-Bite" Advantage
Safety isn't just about chemicals; it's also about fit. A loose mouthpiece can be a choking hazard or cause gum irritation. Our device uses a "boil-and-bite" technology. When heated in hot water, the material becomes soft and pliable, allowing you to create a custom impression of your own teeth. Once cooled, it hardens to maintain that shape, ensuring:
-
A secure fit that stays in place.
-
Maximum comfort for your gums.
-
Effective jaw positioning.
Hygiene Tips
To keep your device safe and clean:
-
Rinse with cool water after every use.
-
Use a soft toothbrush with mild soap (avoid toothpaste as it can be abrasive).
-
Store it in the provided travel case to let it air dry.
Your health is our priority. Sleep safe and sound with Spirit of Life Sleep.
