If you want insights on how to properly clean a night guard, this blog is the perfect piece of reading for you.

How to Clean Your Night Guard for Next Use

If you have just gotten a new one or want to learn how to care for your current appliance in the best manner, these 5 ways to clean your night guard are your best bet.

Brush Using Toothpaste

Bet you didn’t know that you can clean your night guard just like your teeth. Well, this is perhaps the easiest way to do so. The best practice is to keep a separate toothbrush to clean your night guard to avoid cross-contamination. Also, choose a brush with soft bristles and a non-abrasive toothpaste for it.

Follow these steps for a thorough cleanse:

  • Properly wash your night guard with room-temperature water.
  • Put a small amount of toothpaste on the brush and start brushing your night guard gently.
  • Once done, give it a thorough rinse to get all the residue and remove the toothpaste.
  • Allow it to air dry before storing.

Soap and Water

Cleaning a night guard with soap and water is a piece of cake as well and works very well to maintain them.

  • Put your night guard under tap water and let water run through it.
  • Now, put mild, alcohol-free soap to your night guard. Options like antibacterial, castile, or dish soap make it to the list.
  • Use a toothbrush to lightly brush off the soap.
  • Once done, wash it off and let it dry.


Antimicrobial mouthwashes effectively eliminate bacteria and food debris. Additionally, they have an added advantage of providing minty fresh breath as well so that you feel refreshed after wearing them. However, make sure to use the alcohol-free version to prevent damage.

  • Start with rinsing under tap water.
  • Take a full cap of mouthwash and pour it in a clean glass and dilute it with water. Dip your night guard in it and make sure the solution completely submerges the appliance.
  • Soak the night guard for 30 minutes.
  • Remove it and rinse with cool water.
  • Let your night guard dry completely.

Baking Soda

Baking soda eliminates debris and bad odors.

  • Dissolve equal parts baking soda and water in a clean bowl and make a paste.
  • Now, take a toothbrush, dip it into the paste, and start brushing gently.
  • Once done, run it under water and make sure there is no residue left.
  • Let it air dry.

Hydrogen Peroxide and Vinegar

If you are looking for in-expensive and natural ways to clean your night guard, go for vinegar and hydrogen peroxide.

  • Rinse your night guard in cool tap water.
  • Put it inside a clean glass and add enough vinegar to cover it.
  • Let it sit for around 30 minutes.
  • Take your night guard out and rinse it with cool water.
  • Now, take another clean glass or reuse the previous one after thorough washing and add enough hydrogen peroxide to cover it.
  • Wait for another 30 minutes.
  • Wash everything with cool water.
  • Let it dry.

Tips To Store Your Night Guard

  • Do not skip thorough rinsing of your night guard after each use.
  • Let your night guard air dry on a clean, flat surface. Always give it time, around 15-30 minutes, to prevent bacterial growth.
  • When not in use, store your night guard in a ventilated case. Avoid keeping it inside the bathroom due to the high humidity.
  • Be careful not to let pets find your night guard, as it is not their chewy toy.
