TMJ is a problem with the joint that connects your jaw to your skull. It can feel sore, stiff, or tight. You might notice pain in your jaw, face, or even your head. Some people hear a pop or click when they chew or open their mouths. Others grind or clench their teeth, often while sleeping, and don’t even know it. This puts more stress on the joints and muscles. Over time, it can wear down your teeth and make your jaw feel tired. One simple thing can help a lot: a night guard for TMJ.
A night guard goes in your mouth while you sleep. It keeps your teeth from touching and helps your jaw relax. It sounds simple, but it can really change your life.
Do Night Guards Help with TMJ?
Yes, they do. A night guard for TMJ helps in many ways. It gives your jaw a break. It makes sure your top and bottom teeth don’t press or grind against each other at night. That’s when most people grind their teeth. You don’t even know you’re doing it.
Night guards Phoenix, AZ, create a soft barrier between your upper and lower teeth. This space stops them from pressing together. It takes pressure off the jaw joint. It also keeps your muscles from working so hard through the night. The jaw has a chance to relax instead of being in constant tension.
When your Phoenix dentist makes your night guard, they shape it to fit your bite. That’s important. A custom-fit guard is more comfortable and works better than a store-bought one. It stays in place, doesn’t slide, and protects your teeth and jaw the way it should.
Once you start wearing it, your jaw doesn’t grind or clench as much. This means the joint isn’t being pushed or strained all night. Many people feel that their jaws are looser in the morning. It opens and moves more easily. The muscles aren’t as tired. You may even sleep better because you’re not waking up from pain or tension.
The night guard for TMJ also helps prevent damage to your teeth. Grinding can wear down enamel or cause tiny cracks. Over time, that damage adds up. A night guard for TMJ keeps your teeth safe and helps avoid future dental problems.

Should You Use a Top or Bottom Night Guard for TMJ?
Most dentists recommend the top night guard. That’s because it usually stays in place better. The upper teeth don’t move as much, so the guard fits snugly and doesn’t shift. It’s also easier for the dentist to shape it around your bite.
The bottom night guard for TMJ can work, too, but sometimes it feels looser. It might also bump into dental work or feel odd with the tongue. If you have a reason to need a bottom guard, your dentist can tell you. But for most people, the top guard works best for TMJ pain.

Can Wearing a Night Guard Make TMJ Worse?
Usually, it helps a lot. But if the night guard doesn’t fit right, it can cause more problems. It might change how your teeth come together. That can lead to new pain or more tension in your jaw.
Over-the-counter guards from the store don’t always fit well. They’re made for all mouth shapes, not yours. A custom night guard for TMJ is much safer. It’s made just for you. If you feel new pain while using your guard, call your dentist Phoenix.
The biggest issue with a night guard for TMJ is that it doesn’t stop the root cause, which is clenching and grinding. Yes, a night guard helps manage symptoms, but it doesn’t fix the underlying joint problem permanently.
