How Should a Night Guard Fit?

November 4, 2025

If you grind your teeth at night or wake up with jaw pain, headaches, or worn teeth, a night guard could be exactly what you need. But not just any night guard will do—the fit matters just as much as the function.


At SMILE HAUS, we specialize in creating custom night guards that protect your teeth comfortably and effectively. Here’s what you need to know about how a night guard should fit—and why that fit matters.

What Is a Night Guard?

A night guard (also known as an occlusal guard or bite splint) is a removable dental appliance worn during sleep to protect your teeth from bruxism—a condition where you involuntarily grind or clench your teeth.


Night guards can help with:

  • Preventing enamel wear and tooth fractures
  • Reducing tension in the jaw muscles
  • Easing symptoms of TMJ disorders
  • Improving sleep quality by minimizing discomfort


There are different types of night guards, but not all are created equal. At SMILE HAUS, we create custom guards using digital impressions for a highly accurate fit—unlike bulky, store-bought options that can cause more harm than good.

What Does a Proper Fit Feel Like?

A well-fitted night guard should feel:


  • Snug, not tight – It should stay in place without putting pressure on your teeth or gums.
  • Even in bite – Your bite should feel balanced, with no high spots or uneven contact.
  • Comfortable – It shouldn’t cause jaw soreness, gum irritation, or make it hard to breathe or swallow.
  • Stable – It should stay in place throughout the night, without slipping or falling out.


If your night guard feels bulky, uncomfortable, or causes discomfort when you wake up, it likely needs adjustment—or replacement with a properly fitted, custom option.

Common Night Guard Fit Issues (and Why They Matter)

Ill-fitting night guards aren’t just uncomfortable—they can make symptoms worse or damage your teeth. Some issues to watch for include:


  • Loose or falling out during sleep – Common with over-the-counter guards
  • Jaw tension or headaches upon waking – May indicate misalignment or uneven pressure
  • Excess salivation or gagging – Often caused by bulky or improperly trimmed guards
  • Shifting teeth over time – A poor fit can exert pressure that alters tooth position


That’s why customization matters. At SMILE HAUS, our night guards are tailored to your exact bite and anatomy using digital scans, ensuring both comfort and long-term protection.
