You take a bite of your sandwich, and suddenly your jaw has something to say about it.
Maybe it aches when you chew. Maybe you hear a click or pop every time you open wide. Or perhaps your jaw feels tired before you’ve even finished dinner. While it can be tempting to ignore these little annoyances, recurring jaw discomfort may be related to your temporomandibular joint, better known as the TMJ.
First, What Exactly Is Your TMJ?
You actually have two temporomandibular joints, one on each side of your head. They connect your lower jaw to your skull and work along with surrounding muscles, ligaments, and other structures to help your jaw move.
Think about everything you ask these little joints to do in a day. They’re involved when you:
- Chew your food
- Talk and laugh
- Yawn
- Open and close your mouth
- Move your jaw from side to side
When there’s a problem involving the joint or the muscles controlling it, it may be referred to as a temporomandibular disorder, or TMD. However, many people simply use the term “TMJ” when talking about jaw pain and related symptoms.
So, why might your jaw be protesting every time you sit down to eat? Here are five clues.
1. You’re Clenching or Grinding Your Teeth
Your jaw may be working overtime even when you aren’t eating.
Clenching and grinding can put extra strain on your jaw muscles and joints. It may happen while you sleep or during the day when you’re stressed, concentrating, driving, or staring down a particularly long to-do list.
Possible clues include morning headaches, sore jaw muscles, tooth sensitivity, or worn teeth. If your jaw is already tired from hours of clenching, chewing dinner can make that discomfort much more noticeable.
2. Your Jaw Is Clicking, Popping, or Catching
Does opening your mouth come with its own sound effects?
Jaw clicking or popping isn’t always a sign that something is wrong. However, it may be time to have your TMJ evaluated when those sounds happen along with:
- Pain
Limited movement - Stiffnessa
- Catching, or locking,
Pay attention to whether your symptoms are becoming more frequent or interfering with normal activities like eating.
3. Stress Is Settling Into Your Jaw
Stress doesn’t only live in your head. It can show up in your muscles, too.
When you’re stressed, you may unconsciously tighten your jaw, clench your teeth, or tense the muscles in your face, neck, and shoulders. Over time, all that tension may contribute to TMJ discomfort.
Try checking your jaw periodically throughout the day. If your teeth are pressed tightly together while you’re answering emails or tackling your afternoon schedule, consciously relaxing them may help reduce unnecessary strain.
4. Your Food Choices Are Giving Your Jaw a Workout
Chewy bagels, gum, caramel, steak, crunchy snacks. Your taste buds might be thrilled, but a sore TMJ may disagree.
Foods that require lots of chewing can make an already irritated jaw work harder. If your jaw is uncomfortable, temporarily choosing softer foods, taking smaller bites, and giving chewing gum a break may help reduce strain.
You don’t have to swear off your favorite foods forever. The goal is simply to give an irritated jaw a little less work while you determine what’s going on.
5. The Discomfort Is Showing Up Somewhere Else
One tricky thing about TMJ disorders is that symptoms aren’t always limited to the jaw.
Some people may also experience:
- Headaches or temple pain
- Facial soreness
- Ear-area discomfort
- Neck or shoulder tension
- Difficulty opening the mouth comfortably
- Jaw stiffness or fatigue
That’s one reason it can be helpful to look at the bigger picture rather than treating each symptom as an unrelated annoyance.
When Should You Have Your TMJ Checked?
An occasional tired jaw after an especially chewy meal may not be unusual. But recurring pain deserves attention, particularly if your jaw locks, your range of motion changes, chewing becomes difficult, or the discomfort is interfering with your everyday life.
