Choosing the Right Reviv Model: A Practical Guide
Share
If you're new to Reviv and unsure which model is right for you, this guide covers the meaningful differences between models, how to choose based on your situation, and what to expect when you start.
The Three Reviv Models — What Distinguishes Them
Reviv offers three models — R1, R2, and R3 — distinguished primarily by structural robustness. All three use the same flat-plane non-locking design philosophy. The difference is how much structural integrity each provides under clenching load.
This matters because:
A guard must hold its shape under your specific clenching force throughout the night to provide consistent mechanical support. A guard that's too soft for your grinding intensity will compress under load — changing jaw height unpredictably and reducing the consistency of mechanical support. A guard appropriately matched to your grinding intensity maintains consistent height throughout the night.
R1 — First-time users, mild to moderate grinding
- Appropriate for people new to guard use without a history of significant grinding
- Suited to smaller jaw structures
- Lightest structural profile — most comfortable for initial adjustment
- May not provide sufficient structural integrity for heavy grinders
R2 — Regular grinders, consistent morning jaw tension
- Appropriate for people who grind consistently and notice morning jaw tightness regularly
- Suited for people who have worn through lighter guards previously
- More structurally robust than R1 — maintains shape under moderate to significant clenching load
- The most commonly appropriate model for people with established overnight grinding patterns
R3 — Heavy grinders, largest jaw structures
- Appropriate for people with significant overnight grinding intensity
- Suited to larger jaw structures
- Highest structural integrity — designed to maintain shape under the heaviest clenching load
- Appropriate for people who have compressed or worn through R1 or R2 previously
If you're unsure between two models: choose the larger. A guard that's slightly more robust than needed provides appropriate support. A guard that's not robust enough for your grinding intensity will compress under load and provide inconsistent mechanical support.
Choosing Based on Your Situation
"I've never used a guard before and want to start." Start with R1 unless you have specific reason to believe your grinding is heavy. R1 provides appropriate structural support for most first-time users and has the most comfortable initial profile for adjustment.
"I've used guards before but they haven't improved morning jaw tightness." If you've used soft or compressing guards, switching to any Reviv model represents a design change — flat-plane non-locking vs compressing or bite-locking. R2 is the most common appropriate starting point for people with established grinding patterns.
"I've worn through guards relatively quickly in the past." This suggests significant grinding force. R3 is likely the most appropriate model — it provides the highest structural integrity under heavy clenching load.
"My jaw size is smaller / I have a narrower mouth." Consider R1 in the smaller size option. Reviv models are available in multiple sizes — choosing the right size alongside the right model is important for appropriate fit.
"My jaw size is larger / I have a wider mouth." R2 or R3 in larger size options. When between sizes, choose larger.
What to Expect When Starting
Week 1–2: Adjustment period. Initial awareness of the guard in the mouth during sleep. Possible mild jaw awareness upon waking. Possible waking with the guard out in early nights. This is normal — not a sign the guard is wrong for you. Wear it every night regardless of initial comfort.
Week 2–4: Adjustment settles. Guard begins to feel more familiar. Some people notice early reduction in morning jaw tightness. Others take longer.
Month 1–3: Where meaningful trends in morning jaw tightness typically emerge. Track morning jaw tightness — 1 to 10 upon waking — weekly to assess whether consistent use is producing gradual improvement.
Beyond 3 months: Where cumulative mechanical change tends to consolidate with consistent nightly use.
Individual experiences vary significantly. There is no single reliable timeline.
If the Guard Doesn't Feel Right After Adjustment
If significant discomfort, worsening morning jaw tightness, or persistent waking with the guard out continues beyond two to three weeks:
Check model selection. If using R1 and morning jaw tightness is not improving, the guard may be compressing under your clenching load. Consider switching to R2.
Check size selection. A guard that doesn't fit the jaw width appropriately may cause discomfort unrelated to the model's structural properties.
Contact Reviv support. Reviv's support team can advise on model and size selection based on your specific situation.
Consult a dental professional. If significant discomfort persists, professional assessment is appropriate before continuing use.
Reviv is a pre-formed appliance — it is not designed to be heated or reshaped at home. Do not attempt to modify your guard.
Care and Maintenance
Consistent daily care extends lifespan and maintains hygiene:
- Rinse with cool water immediately after removal each morning
- Clean with mild soap and soft brush — not toothpaste
- Rinse thoroughly and air dry completely before storing
- Store in ventilated case — never store wet or in a sealed container
- Weekly deep clean with diluted white vinegar or non-alcohol denture tablets
Replace when the guard shows visible compression, shape change, cracks, or persistent odour despite cleaning.
Expected lifespan: 6–12 months depending on grinding intensity and care consistency. Heavy grinders may need replacement at the shorter end of this range.

When to Seek Professional Assessment Before Starting
Consult a dental professional before purchasing if you have:
- A diagnosed TMJ disorder being professionally managed
- Significant dental restorations, implants, or active orthodontic treatment
- Jaw clicking accompanied by pain or limited mouth opening
- Significant jaw pain
- Any dental or jaw concerns that suggest professional guidance is needed before adding any oral appliance
A consumer oral appliance is not appropriate as a substitute for professionally managed care when that's indicated.
Summary
| Situation | Recommended Model |
|---|---|
| First-time user, no history of heavy grinding | R1 |
| Regular grinder, consistent morning jaw tightness | R2 |
| Heavy grinder, worn through guards previously | R3 |
| Unsure between two models | Choose the larger |
| Smaller jaw structure | R1, smaller size |
| Larger jaw structure | R2 or R3, larger size |
