If you wake up with headaches, a sore jaw, or teeth that feel tender for no obvious reason, there’s a good chance you’re grinding or clenching your teeth in your sleep. Nighttime grinding (bruxism) affects roughly 1 in 10 adults — and because it happens while you’re unconscious, most people don’t know until the damage shows. A custom night guard is the standard first-line fix, protecting your teeth and easing strain on your jaw joints.
Here’s how to tell if you need one, and why a custom night guard from your Lee’s Summit dentist outperforms anything from the pharmacy aisle.
8 Signs You’re Grinding Your Teeth at Night
- Morning headaches, especially around the temples
- Jaw soreness or fatigue when you wake up
- Clicking, popping, or locking when you open your mouth
- Flattened, chipped, or worn-down teeth — your dentist often spots this first
- Increased tooth sensitivity to hot and cold, from worn enamel
- Earaches or facial pain with no ear infection
- A partner who hears grinding sounds at night
- Scalloped tongue edges or cheek damage from clenching
Two or more of these — especially morning symptoms — usually point to sleep bruxism. Worn enamel also explains a lot of “mystery” sensitivity; if cold water makes you wince, grinding may be why, and tooth sensitivity treatment plus a guard addresses both cause and symptom.
Grinding vs. TMJ Disorder: What’s the Difference?
They’re related but not the same. Grinding is the behavior; TMJ disorder (TMD) is a condition of the jaw joint and surrounding muscles. Chronic grinding is one of the most common triggers of TMD — the constant overnight pressure inflames the joint, leading to clicking, restricted opening, and chronic facial pain.
If your symptoms go beyond tooth wear into persistent jaw pain, popping, or locking, you may need more than a guard. Our TMJ/TMD treatment in Lee’s Summit starts with identifying whether grinding, joint inflammation, bite misalignment, or stress is driving the problem.
For stubborn muscle-related TMD, dental Botox is an increasingly popular add-on — small doses relax the overworked jaw muscles that a night guard alone can’t calm. (Yes, the same Botox from our $11/unit offer.)
Custom Night Guard vs. Store-Bought: Honest Comparison
| Custom (dentist-made) | Boil-and-bite (pharmacy) | |
| Fit | Exact mold of your teeth | Approximate, often bulky |
| Comfort / sleep tolerance | High — most adapt in days | Low — many end up in a drawer |
| Durability | 3–5+ years | A few months |
| Bite protection | Calibrated to your bite; protects jaw joint | Cushions teeth only; can worsen some bites |
| Cost | $300 – $800 | $20 – $60 |
| Supervision | Dentist checks wear patterns at visits | None |
The honest take: a boil-and-bite guard is better than nothing for short-term use. But poorly fitted guards can change your bite or concentrate force in the wrong places — and most people stop wearing them because they’re uncomfortable. A night guard only works if it’s actually in your mouth at 2 a.m.
What Happens If You Ignore Grinding?
Untreated bruxism is a slow-motion dental emergency. Over years it leads to:
- Cracked and chipped teeth that need repair — we covered the fixes in how to fix a chipped tooth
- Worn enamel that can’t grow back, causing permanent sensitivity
- Failed dental work — grinding destroys fillings and crowns faster than anything else
- Teeth ground down enough to need dental crowns to rebuild lost height
- Chronic TMD that becomes harder to treat the longer it persists
A $300–$800 guard protecting against thousands of dollars in restorative work is one of the best returns in dentistry.
How a Custom Night Guard Is Made
It takes two short visits. First, we examine your teeth and jaw, confirm bruxism is the issue, and take digital impressions. A dental lab fabricates your guard from durable, BPA-free material calibrated to your bite. At the second visit (about 1–2 weeks later) we fit and adjust it. Most patients fully adapt within a week of nightly wear.
We’ll also check your guard’s wear patterns at each teeth cleaning — those patterns tell us exactly how hard you’re grinding and whether the guard is doing its job.
Stop the Damage Before It Spreads
If you recognized yourself in the symptom list, don’t wait for a cracked tooth to confirm it. Call Stehl Family Dental at (816) 844-7228 or schedule an appointment online — one exam can tell you whether grinding is wearing down your smile while you sleep.
