Roughly 10-20% of adults grind or clench their teeth during sleep. Most don’t know it until a spouse complains about the grinding sound, a dentist points out unusual tooth wear, or they wake up with jaw pain one too many times. A custom night guard from Glisten Dental Studio is the single most cost-effective intervention in dentistry for patients in Gilbert who grind — it protects every tooth in your mouth simultaneously and typically costs less than a single emergency crown replacement.
How we know if you’re grinding
Patients rarely report grinding directly — they report the downstream effects. At comprehensive exams we look for the tell-tale signs:
- Flattened or worn-down tooth edges, especially canines and premolars
- Chipped teeth without a clear trauma history
- Cracks visible on transillumination, particularly on molars
- Tooth sensitivity to cold, especially in the morning
- Tori (bony growths on the inside of the lower jaw or roof of the mouth) — a hallmark of long-term heavy clenchers
- Scalloped tongue edges where the tongue presses against the teeth
- Masseter muscle hypertrophy — enlarged cheek muscles from overuse
- Receding gums in characteristic patterns
- Repeated restoration failure — fillings popping out, crowns debonding, veneers fracturing
If three or more of these show up, you’re grinding even if you don’t know it. A spouse or sleep partner can confirm nocturnal grinding noise. Sleep studies occasionally capture it if a study is being done for another reason.
Why grinding matters (it’s not just jaw soreness)
Teeth can withstand normal chewing forces of roughly 20-40 pounds per square inch without structural damage. Clenching during sleep can exceed 250 pounds per square inch and lasts for hours. The damage is cumulative and irreversible:
- Enamel loss — once enamel is worn off, it doesn’t grow back. Teeth become more sensitive, darker, and more prone to decay.
- Cracked teeth — initially hairline cracks, eventually progressing to fractures that require crowns, root canals, or extractions. We’ve seen single molars cost $3,500+ to restore when they could have been protected for $400.
- Restoration failure — fillings, crowns, and veneers that would normally last 10-15 years fail in 3-5 years under grinding forces. Replacement costs add up over a lifetime.
- Jaw joint damage — chronic muscle overload leads to TMD, headaches, and sometimes degenerative joint changes.
- Root fractures — the worst-case outcome. Vertical root fractures from sustained clenching force can render a tooth unsalvageable.
A custom night guard prevents all of this by placing a protective surface between your upper and lower teeth. Instead of grinding enamel against enamel, you grind acrylic against acrylic — and acrylic is replaceable.
Custom vs over-the-counter guards
Pharmacies sell boil-and-bite guards for $20-$50. Online companies sell slightly better guards for $100-$300 from mail-in impressions. Custom guards from a dentist run $400-$700. The price difference reflects real differences in fit and outcome.
Boil-and-bite guards: thick, bulky, ill-fitting. Tend to fall out during sleep. Provide temporary protection but can actually worsen bite problems over months because they don’t fit your specific occlusion. Fine for a few weeks while you schedule a custom guard; not an acceptable long-term solution for most patients.
Mail-in impression guards: better than boil-and-bite but still not as precise as an in-office scan. The impression technique is harder for patients to get right without supervision, which affects fit. Fit issues mean reduced comfort, reduced wear adherence, and reduced effectiveness.
Custom in-office guards at Glisten Dental Studio: digital scan of your teeth (no goopy impression material), lab fabrication from high-quality acrylic or dual-laminate materials, in-person fitting with adjustments. Fits precisely, stays in place through the night, comfortable enough for most patients to wear consistently. Lasts 3-7 years depending on grinding intensity.
Types of custom night guards
Hard acrylic (standard occlusal splint)
Rigid acrylic material, worn on either the upper or lower arch. Most durable, best for heavy grinders, most predictable outcomes. Typical at Glisten Dental Studio. Cost: $400-$600.
Soft guards
Flexible thermoplastic material. More comfortable for mild grinders or patients who’ve never worn a guard before. Less durable — heavy grinders chew through them in months. Cost: $300-$450. We typically don’t recommend these for moderate-to-severe grinders; the durability tradeoff isn’t worth it.
Dual-laminate (soft inside, hard outside)
Combines comfort of soft material with durability of hard material. Good middle-ground for many patients. Cost: $500-$700.
NTI-style anterior-only devices
Small device that covers only the front teeth, designed to prevent molar contact and reduce clenching force. Effective for some patients with primarily tension-driven clenching. Less commonly used today because long-term unsupervised wear can cause posterior tooth over-eruption. Cost: $400-$550.
We recommend the type that best fits your grinding pattern and clinical situation — no one-size-fits-all default.
The fitting process
- Exam and assessment. We document existing wear patterns, identify any teeth at high risk, and confirm a night guard is the right intervention. Some patients benefit more from addressing underlying TMD; others need orthodontic evaluation first.
- Digital scan. 5-10 minutes. Replaces old-style impression trays.
- Lab fabrication. 10-14 days.
- Delivery and fitting. We seat the device, check the bite, adjust any high spots, demonstrate insertion and care. Typically 30-45 minutes.
- 2-week follow-up. Quick check to ensure comfort and adherence. Minor adjustments if needed.
- Annual follow-ups. Wear checks, replacement planning when the guard reaches end of life.
Caring for your night guard
Rinse with cold water after each use. Brush gently with a soft toothbrush (no toothpaste — abrasive ingredients scratch acrylic). Weekly soak in denture cleaner or a dental appliance cleaner. Store in the ventilated case provided — don’t leave it in a sealed container when wet. Keep out of hot cars and direct sun (heat warps the material).
Replace when visible wear, cracks, or odor develops. Don’t try to repair cracks with superglue — cyanoacrylate is toxic and the fix is temporary.
Is it worth it?
On pure economics: a custom night guard at Glisten Dental Studio costs $400-$700 and protects every tooth in your mouth for 3-7 years. A single replacement crown costs $900-$1,800. A root canal plus crown is $1,500-$3,000. An implant to replace a fractured tooth is $4,500-$6,500. If a night guard prevents a single one of these outcomes across its lifespan, it has paid for itself multiple times over.
