How Often Should You Replace a Night Guard?
According to Cleveland Clinic, custom-made mouth guards can last several years with proper care, while store-bought options may need more frequent replacement. However, factors such as how often you wear your night guard and how much wear it experiences can affect its lifespan. Regular dental checkups can help identify signs of damage, such as cracks or changes in fit.

Signs You Need a New Night Guard
Over time, your night guard may become less effective due to wear, damage, or changes in fit. Replacing it when needed helps ensure your teeth continue receiving proper protection from grinding and clenching.
Here are the common signs that it’s time to replace your night guard:
Your Night Guard No Longer Fits Properly
A night guard should fit comfortably and securely over your teeth. However, changes to your smile can affect how well your guard fits. If you recently had dental work, such as fillings, crowns, or other procedures, your bite and tooth shape may have changed, causing your night guard to feel loose, tight, or uncomfortable.
A poorly fitting night guard may not provide the protection your teeth need, so it may be time to consider getting a replacement. Changes in how your bite feels can also be a sign that your night guard no longer fits properly. Learn more: Bite Feels Weird After Wearing a Night Guard? Here’s Why
Your Night Guard Shows Signs of Wear and Damage
Over time, repeated grinding and clenching can wear down your night guard. Look for signs such as cracks, thinning areas, rough edges, or changes in shape that may reduce its ability to protect your teeth. If your night guard shows visible wear or damage, it may be time for a replacement.
Your Night Guard Has Persistent Stains or Odor
Discoloration and odor can develop after months or years of use, especially if bacteria and buildup accumulate over time. While regular cleaning can help maintain your night guard, stubborn stains or unpleasant smells may be a sign that it needs to be replaced.
A dirty night guard may also contribute to bad breath. Learn more about the signs that your mouthguard could be affecting your breath and how to fix it: 5 Signs Your Mouthguard Is Causing Bad Breath — and How to Fix It
You Lost or Accidentally Damaged Your Night Guard
Sometimes replacement isn’t caused by normal wear and tear. Night guards can be misplaced during travel, accidentally thrown away, damaged by pets, or exposed to heat that changes their shape.
