TL;DR
- The daily cleansing routine includes rinsing the guard immediately and gently brushing it with a soft-bristled toothbrush and mild, non-abrasive toothpaste. You must also rinse the night guard and air-dry it before storing it in a container.
- Thorough cleaning once a week involves a deep clean with cleanser tablets, a vinegar solution, and baking soda.
- However, remember to follow the manufacturer’s guidelines and your dentist’s instructions to make the most of your night guards.
- Avoid using hot or boiling water, alcohol-based products, and dishwashers for cleaning the night guards.
- You must replace your guard based on the intensity of teeth grinding, and the timeframe may vary from 1 to 5 years.
- If you notice signs like visible cracks, worn-out surfaces, foul smell, and changes in the fit, it’s time to change your night guard.
Why Regular Night Guard Cleaning is Important?
Your night guard spends hours in your mouth every night, so it is bound to collect bacteria and plaque over time. If it is not cleaned properly, that buildup becomes visible, starts to smell, and can even affect the fit of the mouthguard.
That is why knowing how to clean nightguards is important. A simple, consistent routine can keep it fresh, comfortable and doing its job properly. It also ties into preventative dental care. When your night guard is clean, you are less likely to experience unnecessary bacterial buildup that could affect your oral health.
The best part is that this does not take much effort. Just a few minutes each day, along with some extra care during the week, is usually enough to keep it in good shape. This blog details safe and effective methods you can use to clean your night guard on a daily and weekly basis.
What is the Right Daily Routine for Cleaning Your Nightguard?
At Norwood Dental, our doctors, Dr. Daniel Ross, Dr. Brandon Bussler, and Dr. Kristina Lecount, recommend following these simple tips to keep your appliance in great shape:
1. Rinse the Night Guard Immediately
After taking out your night guard, rinse it right away with lukewarm water. This helps wash away saliva and debris and prevents the accumulation of harmful compounds that harden over time, making them more difficult to remove with a toothbrush and toothpaste.
2. Use a Soft Toothbrush and Mild, Non-Abrasive Soap
Use a soft-bristled toothbrush and mild soap or non-abrasive toothpaste. You should not use regular toothpaste because it can create tiny scratches on your night guard that bacteria can grow in.
3. Use the Right Brushing Technique
Use mild pressure and gently brush the entire surface of your night guard, including both sides, the inside grooves, and the areas where your teeth contact it.
4. Rinse the Nightguard Before Storage
Be sure to rinse your nightguard well with lukewarm water after brushing to remove any soap or paste residue. Also, check for any buildup to make sure it is clean and ready to be stored.
How to Clean a Nightguard Weekly?
Along with daily washing and gentle scrubbing, having a thorough cleaning process each week can aid in removing stubborn residue and/or odor. Here’s what we at Norwood Dental suggest:
1. Use Cleanser Tablets
When learning how to clean night guards, perhaps the most recommended method would be to soak your appliance in denture nightguard cleaning tablets. These tablets effectively clean the night guard without damaging the actual material. They are also great for people who want to know how to clean a night guard mouthpiece without resorting to using abrasives.
- Pour warm water into a cup (do not use hot water)
- Put the cleanser tablet in the glass
- Submerge the nightguard in the solution for 15-20 minutes
- Rinse the nightguard until it is clean and dry before wearing it
2. Vinegar and Water Mixture
A simple and practical option is an overnight soak using vinegar and water. Vinegar is effective at dissolving mineral deposits and mild plaque buildup. This solution will work well for hard residue; however, you should not use this method excessively. Using it for long periods might damage certain materials.
- Combine with equal parts white vinegar and lukewarm water
- Let soak overnight for 15-30 minutes
- Rinse completely with cool water
3. Baking Soda for Odor Control
Baking soda is an excellent way to eliminate lingering odor on your night guard. This is effective without being aggressive or abrasive and will serve as a safe way to add to your routine for cleaning night guards.
- Dissolve one tbsp. of baking soda in one cup of water
- Let it soak for 30-60 minutes
- Rinse very well before reinserting your nightguard.
Why Manufacturer and Dentist Instructions Matter?
Different types of nightguard materials (such as soft thermoplastic and hard acrylic) require different cleaning methods to avoid damage. Therefore, what works well for one could be very ineffective for another. You should always follow the recommended cleaning methods provided by the dentist or manufacturer.
Our team at Norwood Dental will provide tailored cleaning instructions for your personal night guards to ensure cleanliness and maintain the structural integrity of your appliance. Alongside that, routine visits allow us to professionally clean the appliance, check for cracks, and catch any wear before it becomes a bigger issue.
What not to Do When Cleaning Your Nightguard?
At Norwood Dental, we advise patients to be mindful of what they use when cleaning their night guard, as the wrong methods can damage the material or affect its fit. Here’s what to avoid:
- Hot or boiling water, as it can warp the shape and affect the fit
- Toothpaste with abrasive ingredients, which can leave scratches where bacteria can build up
- Harsh chemicals or bleach, as they may damage the material and leave unsafe residues
- Dishwashers or washing machines, since heat and movement can distort or crack the appliance
- Alcohol-based cleaners, which can dry out and weaken the material over time
- Hard-bristled brushes, as they can wear down the surface and make cleaning less effective
How to Properly Store Your Nightguard?
How you store your night guard matters just as much as how you clean it. Here are some storage tips from our experts at Norwood Dental:
- Let it air-dry fully before putting it away, as trapped moisture can lead to bacterial growth and odor.
- Use a case with small ventilation holes to allow airflow and prevent dampness.
- Keep it away from heat and direct sunlight, which can alter the shape and affect the fit.
- Rinse it before storing, even after cleaning, to remove any remaining residue.
- Clean the storage case regularly, since it can collect bacteria just like the appliance.
- Store it in a safe place to avoid accidental damage, warping or misplacement.
When Should a Night Guard Be Replaced?
Replacement timelines will depend on how much you grind your teeth and how often you use your night guard. Experts at Norwood Dental suggest the following replacement guidelines:
| Severity of Grinding | Replacement Timeframe |
| Mild | 3-5 years |
| Moderate | 2-3 years |
| Severe | 1-2 years |
What are the Signs You Need to Replace Your Nightguard?
Even with consistent care, a night guard will eventually need to be replaced. Here are some of the most common signs to watch out for:
- Visible cracks or thinning
- Flattened or worn bite surfaces
- Persistent odour even after proper cleaning
- Changes in fit or comfort
- Increased discomfort in the jaw

Taking care of your night guard is one of the simplest things you can do to protect both your appliance and your oral health. Daily rinsing, gentle brushing, weekly deep cleaning, and proper storage all go a long way in keeping bacteria at bay and helping your guard last as long as it should.
