How To Remove Yellow Stains From Night Guards?

Regular cleaning is important to maintain the cleanliness as well as the color of your guard. As Healthline makes clear, you have plenty of options to choose from when it comes to cleaning your night guard. Is your night guard turning yellow? Then you need to think of regular cleaning. For daily cleaning, try:

  • Toothpaste: Use a soft-bristled toothbrush to gently brush the night guard with a nonabrasive toothpaste. Rinse thoroughly, and be sure the appliance is dry before you store it. Be sure not to use hot water, as this can deform the guard
  • Baking Soda: Make a paste with baking soda and water. Apply it with a soft toothbrush. Rinse your night guard, and allow it to dry.
  • Soap: Select a mild, alcohol-free soap. An antimicrobial soap, dish soap, or castile soap will work well. Apply the soap with a soft toothbrush. Rinse and dry thoroughly.
  • Mouthwash: Use cool water to rinse your mouthguard. Choose a dish that your night guard will submerge in. Pour in one cap of alcohol-free mouthwash. Then, place your mouthguard in it. Add enough water to cover the appliance. Let it soak for 30 minutes. Drain the dish. Rinse your mouthguard, and allow it to dry.

Every week or two weeks, it is highly recommended that you deep clean your night guard as well. However, it's a matter of balance. Cleaning away bacteria is essential, but frequent use of harsh chemicals could have a negative impact on the durability of your dental device. Generally, monthly deep cleanings are recommended in order to remove yellow stains from night guards. In addition, it's a good idea to perform a deep cleaning after an illness to ensure that no germs are lingering. When it is time for a deep cleaning, you can break out these slightly stronger cleaning agents:

  • White Vinegar And Hydrogen Peroxide: This one-two punch starts with a 30-minute vinegar soak. After a refreshing rinse in cool water, follow up with a 30-minute soak in hydrogen peroxide. Then, rinse again before allowing the night guard to dry.
  • Denture Cleaners: Over-the-counter denture cleaning solution can be a handy way to deep clean your night guard. Be sure to choose a nonabrasive solution. You will also want to be mindful of any fragrances or dyes. Read the instructions on the packet, but be careful not to soak your night guard too long. Extended exposure may damage your appliance.

Don't neglect your night guard case. Keep your mouthguard case clean and dry as well because bacteria can accumulate there if not cared for properly. Fortunately, cleaning a night guard's case is simple. Just wash it with dish soap and warm water. Then, let it dry thoroughly. Cleaning your night guard's case every few days is generally sufficient.

When Should I Replace My Night Guard?

The cleaning methods mentioned above would help to remove yellow stains from night guards. But nothing lasts forever, including a night guard. There are a few different indicators that could signal it is time for a new night guard:

  • Black Spots: If you notice black or greenish-black spots on your night guard, you may have black mold on your night guard. This can be a real health concern, so it is definitely time to replace your night guard.
  • Calcium Buildup: Calcium buildup overtime can cause an ill fit and prevent the night guard from doing its job.
  • An Unpleasant Odor: If your night guard has developed an unpleasant smell that persists despite a deep cleaning, it's probably a sign that you should replace it.
  • Wear: Your night guard absorbs the pressure from teeth grinding as it protects your teeth. If you've been using it for a while, and it's getting worn out, then it may be time for a new one. Signs of wear may be obvious: tears, cracks, or holes. Or, they might be more subtle. It might fit more loosely, be slightly deformed, or be thinner from consistent grinding.

What Causes Discolorations on a Night Guard?

As Oral Care Experts point out, night guards turning yellow or generally dental night guards turn colors when they aren't cleaned off and dried properly before being returned to their case. These conditions create a breeding ground for any of the bacteria that lurk in saliva to build up and flourish. Unfortunately, bacteria buildup doesn't just pose a threat to your night guard.

Cleaning your night guard properly protects both you and your night guard from ill effects.
