Quick Answer
The most preferred night guard type is typically a custom-fit dual-laminate (hard/soft hybrid) guard. It combines comfort, durability, and effective protection, making it the top choice for many people who grind or clench their teeth.
But the “best” type depends on your grinding severity, jaw sensitivity, and personal comfort preferences. Below, we’ll explore all the main types of night guards and how to decide which is right for you.

Why Choosing the Right Night Guard Matters
Wearing a night guard is one of the most effective ways to protect your teeth from bruxism (grinding and clenching). But not all guards are created equal.
A poorly fitting guard may cause soreness, shift your bite, or end up in the nightstand.
The wrong material can feel bulky or wear out too quickly.
The right type improves comfort, increases wear consistency, and offers long-term protection against tooth wear, jaw strain, and costly dental damage.
