Do You Really Need a Mouthguard? What Your Dentist Might Not Tell You

If you’ve ever told your dentist your jaw hurts,
Or mentioned you wake up clenching,
Or showed signs of wear on your teeth…

You’ve probably heard it:

“Just get a mouthguard.”

End of conversation. No further questions.

But here’s the real talk:

Not all mouthguards are the same.
Not everyone actually needs one.
And what most dentists don’t explain?
A mouthguard can help or harm—depending on what it does to your jaw, posture, and airway.

This post breaks it down. No fluff. No scare tactics. Just facts.

🧠 Why Dentists Recommend Mouthguards

Let’s start with what they do tell you:

Dentists recommend mouthguards to:

• Protect teeth from grinding (bruxism)
  
  
• Reduce wear and chipping
  
  
• Prevent bite changes
  
  
• Avoid cracked crowns and fillings
  
  
• Relieve pressure on the jaw joint (TMJ)
  

And they’re not wrong—if that’s all you’re solving for.

🤫 What They Often Don’t Mention

1. Not All Mouthguards Support Jaw Alignment

Some guards:

• Lock your jaw backward
  
  
• Force a bite that compresses the TMJ
  
  
• Cause more clenching over time
  
  
• Disrupt your airway during sleep
  

This is especially true with:

• Boil-and-bite guards from the pharmacy
  
  
• Bulky acrylic splints meant only to protect teeth
  
  
• Sports guards used incorrectly for sleep
  

2. They Don’t Retrain Bad Habits—They Mask Them

Protection is great.
But if your jaw is clenching due to stress, posture, or poor breathing mechanics?

A basic mouthguard doesn’t fix that.

It just puts rubber between your teeth—and hopes for the best.

😬 When You Don’t Need a Mouthguard (Yet)

You might not need one if:

• You have no signs of tooth wear
  
  
• You’re not waking up sore
  
  
• You’re not clenching during work or sleep
  
  
• You’re actively addressing posture and tongue position
  
  
• You’re already breathing exclusively through your nose
  
  
• You’ve ruled out other causes (sinus issues, sleep apnea, etc.)
  

But if you're not doing those things perfectly?
 Then yeah, you probably do need support.

✅ When You Absolutely Need a Mouthguard

• You wake up with jaw soreness or tightness
  
  
• You hear or feel clicking when you chew
  
  
• You’ve chipped teeth without knowing how
  
  
• You get regular tension headaches
  
  
• Your dentist sees enamel wear
  
  
• You clench while you work
  
  
• You breathe through your mouth at night
  
  
• You want to fix your posture + facial symmetry
  

And here’s the key:

You don’t just need a mouthguard.
You need the right kind.

🦷 So What Kind of Mouthguard Should You Use?

❌ Not a basic guard from the pharmacy

They’re too soft, poorly fitted, and often make clenching worse.

❌ Not a sports mouthguard

These are designed for impact, not decompression or posture.

❌ Not a dentist splint (for most people)

Great for extreme grinding—but often bulky, expensive ($800+), and built to block—not retrain.

🧠 FAQ

Q: Can a mouthguard fix TMJ?
It can help—but only if it decompresses the joint and supports rest posture. That’s what Reviv is built to do.

Q: What if I already use a mouthguard from my dentist?
If it’s not relieving tension or improving sleep/posture—you may need to switch. Reviv is a safe at-home option.

Q: How is Reviv different from boil-and-bite guards?
It molds to your resting jaw, not your clenched bite. Plus, it’s thinner, more breathable, and supports retraining—not just protection.

Q: How long before I notice a difference?
Most users feel relief within 3–5 nights, with deeper changes in posture and facial tension over 2–4 weeks.
