Why You Need to Replace Your Night Guards Every 6 Months  | Remi

If you wear a night guard, it’s essential to replace it regularly. Most medical professionals recommend replacing your night guard every six months, as this helps keep your teeth healthy and ensures you get a good night’s sleep. But how do you know when to replace your night guard? Let’s look at the importance of regularly replacing your night guard and the signs indicating it’s time for a new one - after all, it sustains the force of your jaw muscles every night!

Remi Night Guards

Regularly replacing your night guard is important for a few reasons:

1. Wearing a night guard helps keep your teeth and jaw healthy. Wearing a night guard each night effectively safeguards against tooth wear during sleep. By creating a physical barrier between teeth and other areas of the mouth, these dental night guards provide peace of mind by assuring your pearly whites remain pristinely intact.

2. Regularly replacing your night guard is essential to ensure a restful slumber. By wearing a night guard every night, you significantly decrease the chance of encountering toothache or other dental issues during the late-night hours - an issue that could otherwise be very inconvenient!

3. The plastic used in these devices often wears down over time and may no longer be properly fitted within the mouth. If you have been using it for more than six months, then it is time to invest in a new one!

4. Bacteria can accumulate on it over time, leading to odors and irritated gums that may reduce the quality of sleep you experience with it - so regular replacement ensures that your night guard protector stays germ-free to allow for restful slumber without any interruptions or discomfort.

Signs You Need to Replace Your Night Guard

So what are the signs that it's time to replace your night guard? Here are several signs that it's time for a new one:

1. Your Night Guard is Frayed or Damaged 

If your night guard is frayed, damaged, or has come loose, it's time to replace it. This is because wearing a frayed or damaged night guard can cause damage to your teeth and jaw and lead to toothache and other dental problems in the middle of the night.

2. You Experience Frequent Soreness or Pain in Your Jaws While Wearing the Current Night Guard

If you experience frequent soreness or pain in your jaws while wearing your current night guard, it's time to replace it. This is because, over time, the worn-out plastic used in most night guards can cause these types of problems.

3. Your Night Guard does Not Fit Properly

If your night guard does not fit properly, it is not creating a proper barrier between your teeth and the rest of your mouth. This can lead to tooth grinding and jaw clenching, both detrimental to oral health.

3. You're Wearing a Night Guard that's Too Small or Too Big

If you're wearing a night guard that's too small; it won't protect your teeth and jaw effectively. This is because a night guard must fit closely around your teeth to be effective. If the night guard is too small, it might not fit properly and cause toothache and other dental problems in the middle of the night.

4. Your Teeth Feel Looser or More Sensitive After Wearing the Same Night Guard

If your teeth feel looser or more sensitive after wearing the same night guard for a period of time, replace it. This is because wearing a night guard can help to protect your teeth and jaw by creating a physical barrier between your teeth and the rest of your mouth. However, if you're experiencing this symptom, it might be a sign that your night guard isn't fitting properly or is damaged. 

5. Your Current Night Guard Has Started to Lose Its Shape or Color

If your current night guard has begun to take on an unappealing appearance or become flimsy, it may be time to replace it. After all, the plastic used in such guards can become brittle over time, ultimately resulting in their breaking or becoming unsightly.

6. You're Experiencing More Difficulty Breathing While Wearing Your Night Guard

If you experience difficulty breathing, you should consult a medical professional.  If your difficulty in breathing persists when you're wearing your night guard, it may be time to replace it. This is because a poorly-fitted or damaged appliance can impede airflow and result in interrupted sleep during the wee hours of the night - something that could potentially exacerbate existing respiratory issues.

7.  You May Have Noticed Your Teeth Shifted Ever so Slightly

This movement may not be noticeable at first, but it can lead to an uncomfortable night guard fit over time. Luckily, several factors may prompt this change - such as simple behaviors, including chewing or speaking. 

8. You've Recently Completed Some New Dental Work 

In such instances, it is advisable to replace your current night guard with a replacement once the dental work has concluded to maintain optimal protection against damage. Examples of new dental work include tooth removal, crowns, dental implants, veneers, or starting to wear aligners. After this dental work, consider replacing your current night guard with a new one and then every six months.

The Bottom Line

Maintaining proper oral hygiene is essential for both dental health and overall well-being. Replacing your night guard every six months helps ensure that it fits properly so you can enjoy a good night's sleep without any distractions or discomfort. Keep an eye out for signs like loose teeth, soreness in jaws, loosening of the fit of the night guard, excessive bacteria build-up, etc., as these are all indicators that it might be time for a replacement! With regular replacement, you will surely enjoy many peaceful nights of restful sleep!
