Night Guard vs Splint vs Reviv: What’s Right for Your Jaw Pain?

Here’s the no-fluff, side-by-side breakdown of Night Guards vs Splints vs Reviv, what each does (and doesn’t do), and how to pick the one that actually helps.

What Is a Night Guard?

A night guard is a plastic shield you wear over your teeth—usually while sleeping—to prevent tooth grinding and clenching (bruxism).

Think of it like a helmet for your teeth.

Pros:

• Protects enamel from grinding
  
  
• Reduces tooth sensitivity
  
  
• Minimizes damage to crowns/fillings
  

Cons:

• Doesn’t reposition the jaw
  
  
• Doesn’t relieve TMJ pressure
  
  
• Doesn’t retrain muscle patterns
  
  
• Can actually worsen jaw posture over time

What Is a Dental Splint?

A splint is a more precise dental appliance that can alter jaw position and is usually used for TMJ treatment or post-surgery stabilization.

It’s often prescribed by a neuromuscular dentist or orofacial pain specialist.

Pros:

• Can reposition jaw
  
  
• Reduces joint inflammation
  
  
• May be helpful for severe TMJ dysfunction
  

Cons:

• Bulky and expensive
  
  
• Requires professional fittings and adjustments
  
  
• No muscle retraining
  
  
• Often uncomfortable for long-term use

What Is Reviv?

Reviv is not a splint.
It’s not a traditional night guard either.
It’s a biomechanically engineered mouthguard designed to:

• Reposition the jaw to its natural rest position
  
  
• Retrain overactive facial and jaw muscles
  
  
• Relieve chronic tension and TMJ symptoms
  
  
• Restore posture from the jaw down to the spine
  
  

It’s designed around posture science, jaw alignment, and neuro-muscular decompression.

Pros:

• Repositions AND retrains
  
  
• Helps correct posture and sleep position
  
  
• Improves nasal breathing
  
  
• Aesthetically improves jawline symmetry
  
  
• Comfortable for long-term use
  
  

Cons:

• Not made for post-surgical stabilization
  
  
• Not a “quick fix”—works progressively over weeks

Real Talk: Why Most Guards Fail

Let me guess.
You’ve tried:

• Drugstore guards that made things worse
  
  
• Dentist guards that cost $600+
  
  
• Splints that felt like medieval torture devices
  

None of them addressed the root problem:
Jaw misalignment + muscle memory + posture collapse

That’s what Reviv is designed to solve.

FAQs

1. Is Reviv a splint or a night guard?
Neither—it’s a third category: a therapeutic oral appliance built on posture science and jaw neurology.

2. Can I use Reviv without a dentist?
Yes. It’s designed for direct-to-consumer use.

3. Does Reviv hurt to wear at first?
No. It’s comfortable by design and adjusts over time as your jaw relaxes.

4. How long until I feel relief?
Many users report noticeable relief in 7–14 days. Long-term changes take 6–8 weeks.

5. Will it stop me from clenching?
Yes—by retraining the habit loop, not just cushioning it.

Final Verdict

• Night guards protect but don’t fix.
  
  
• Splints correct but don’t retrain.
  
  
• Reviv protects, corrects, retrains, and relieves.
  

If you want real TMJ relief, choose the only option designed around the entire body, not just the teeth.
