Night guards, also known as mouthguards or occlusal splints, are custom-made or boil-and-bite devices designed to protect teeth from grinding (bruxism) and clenching. But how long do these protective devices actually last? The answer isn't a simple number; it depends on several factors. This guide will explore the lifespan of night guards, common issues, and when it's time for a replacement.
How Long Should a Night Guard Last?
The general lifespan of a night guard ranges from one to three years. However, this is just an estimate. Several factors influence how long your night guard remains effective and safe for use.
What Factors Affect the Lifespan of a Night Guard?
Several factors determine how long your night guard will last:
-
Material: Different materials have different durability levels. Harder acrylics tend to last longer than softer thermoplastic materials. Custom-made night guards, often made from higher-quality materials, typically outlast boil-and-bite varieties.
-
Usage: Daily use naturally wears down a night guard. Frequent grinding or clenching will accelerate wear and tear, shortening its lifespan.
-
Care: Proper cleaning and storage significantly impact a night guard's longevity. Neglecting proper hygiene can lead to faster deterioration and the build-up of bacteria.
-
Oral Habits: Certain oral habits, like chewing on the night guard or using it for purposes other than its intended use (e.g., biting nails), can damage it prematurely.
-
Manufacturing Quality: A poorly made night guard, whether custom-made or boil-and-bite, is more prone to cracking or breaking, reducing its useful life.
How Often Should I Replace My Night Guard?
There's no one-size-fits-all answer, but here are some key indicators that it's time for a replacement:
-
Visible Wear and Tear: Cracks, chips, significant wear, or changes in the fit are clear signs your night guard needs replacing. A worn-down guard won't offer the same level of protection.
-
Discomfort or Irritation: If your night guard starts causing discomfort, pain, or sores in your mouth, it's time to seek a new one. This could indicate a change in your bite or that the guard has become misshapen.
-
Loss of Effectiveness: If you notice an increase in teeth grinding or clenching symptoms, even while wearing the night guard, it may be losing its effectiveness.
-
Changes in Your Bite: Your bite can change over time due to various reasons. If your night guard no longer fits comfortably, it's a clear sign of needing a replacement. It's crucial for proper protection and alignment.
What Happens If I Don't Replace My Night Guard in Time?
Continuing to use a worn-out or damaged night guard can lead to several problems:
-
Reduced Protection: A damaged guard won't effectively protect your teeth from grinding or clenching, potentially leading to further damage.
-
Increased Discomfort: A poorly fitting or damaged night guard can cause jaw pain, headaches, and discomfort.
-
Increased Risk of Infection: A dirty or damaged night guard can harbor bacteria, increasing the risk of oral infections.
How Can I Extend the Life of My Night Guard?
Here are some tips to maximize the lifespan of your night guard:
-
Clean it regularly: Rinse your night guard thoroughly with water after each use and clean it with a toothbrush and mild soap at least once a day. Avoid harsh chemicals or abrasive cleaners.
-
Store it properly: Keep your night guard in its case when not in use to prevent damage or contamination.
-
Avoid extreme temperatures: Do not expose your night guard to extreme heat or cold, as this can warp or damage it.
-
Avoid chewing on it: Refraining from chewing on your night guard will significantly prolong its life.
-
Regular Dental Checkups: Regular visits to your dentist allow for monitoring of your night guard and overall oral health.
By understanding the factors influencing their lifespan and taking proper care, you can ensure your night guard provides optimal protection for as long as possible. Remember, consulting your dentist is crucial for determining when a replacement is necessary. They can assess your specific situation and recommend the best course of action for maintaining healthy teeth and a comfortable jaw.
