Osmo Biteguard EU

My gums were a bit sore the first night, but by day three the custom fit felt completely natural. It stays put through clenching and hasn't changed shape or durability in the warm water we have here. Exactly what my dentist recommended.

It fit right out of the box and stays in place during the night, which was my biggest worry. The standard sizing seems true to the description, and I’ve had no soreness or shifting after a week of use.

The fitting kit took a bit of patience to get right, but once I pressed the guard into the mold it came out snug and comfortable. It's been a week of wear and it holds up fine during sleep, though I wish the case it ships with was a touch sturdier for travel.
