The Sentinel Promise: Perfect fit or we remake it free.
If your night guard hurts your teeth, you’re not alone. While a little pressure is normal at first, ongoing pain usually means the guard needs an adjustment, a different material, or a new fit. This guide—part of Sentinel Mouthguards’ Comprehensive Guide to Night Guards—explains why discomfort happens, what’s normal vs. not normal, and the exact steps to fix a painful night guard so you can sleep comfortably and protect your teeth with confidence.

Taking a dental impression at home doesn’t have to be intimidating. With the right tray, proper timing, and a few simple tips, you can capture a precise mold that ensures your custom night guard fits comfortably and protects your teeth.
