Your night guard works hard while you sleep. It acts as a reliable shield for your teeth, absorbing the pressure from grinding or clenching throughout the night. If you are looking for a reliable dental office near you, it is essential to understand that these oral appliances do not last forever. Even the highest quality materials will eventually wear down.
Regularly checking your nightguard ensures your smile stays protected. If you continue to wear a damaged or thin guard, you might start feeling jaw pain or noticing tooth wear again. Knowing the red flags can help you decide when it is time to visit a professional for a new one.
1. Visible Cracks or Tears
Physical damage is the most obvious sign of wear. Check your guard closely and under a bright light. Your wooden surfaces are compromised if you see small cracks, fractures, or deep scratches. Because they are so tiny, they can trap bacteria as well.
2. The Guard Feels Loose
A night guard should fit snugly against your teeth. It should stay in place even if you open your mouth. If it starts to feel loose or shifts while you sleep, it can no longer provide the right level of protection. When looking for night guards near you, remember that a custom-fit piece is always safer than a loose, worn-out one.
3. Thinning Material
Over time, constant grinding wears down the plastic or acrylic. You might notice certain areas, usually near the molars, looking much thinner or even see-through. If the material becomes too thin, your top and bottom teeth may touch while you grind. This defeats the device’s entire purpose.
4. Changes in Your Bite
Does your jaw feel “off” when you wake up? If your teeth do not seem to fit together correctly in the morning, your nightguard might be warped. A warped guard can shift your teeth into the wrong positions. This can lead to long-term alignment issues that are expensive to fix.
5. Persistent Discoloration or Odor
It is normal for a guard to lose some of its sparkle over time, but deep yellowing or white calcium deposits are signs of aging. If the guard has a foul smell or taste even after thorough cleaning, it is likely porous and harbors bacteria. Replacing it is the best way to maintain your oral hygiene.
6. Recurring Jaw Pain or Headaches
The main job of a night guard is to prevent symptoms of bruxism. If you start waking up with a sore jaw, earaches, or tension headaches again, your guard is likely failing. It may have lost its cushion, or the fit has changed enough that your muscles are straining.
7. Chips and Small Pieces Breaking Off
If you notice small bits of plastic in your mouth when you wake up, stop using the guard immediately. Sharp edges can cut your gums or tongue. Swallowing small pieces of the guard is also a safety hazard. This is a clear signal that the material has reached the end of its lifespan.

Frequently Asked Questions
What is the average lifespan of a night guard?
Most custom night guards last between one and five years. This depends on how heavily you grind your teeth and how well you clean the appliance daily.
Can I wear a cracked nightguard?
It is not recommended. Cracks can harbor bacteria and can also pinch or cut your soft oral tissues. A cracked guard is also more likely to break further while you are sleeping.
How do I keep my nightguard in good shape?
Rinse it with cool water every morning and clean it with a soft toothbrush and non-abrasive soap. Keep it in a ventilated case to prevent mold and bacterial growth.
Does insurance cover a replacement guard?
Many dental insurance plans cover a portion of the cost for a new guard every few years. It is best to check with your provider to see what your specific plan allows.
