Custom Dental Nightguards for Teeth Grinding & TMJ Relief in Southeast Portland, OR
Protect your natural enamel, sensitive gumlines, and porcelain crowns from nighttime clenching and grinding with a precision 3D-scanned custom nightguard.
Many people who clench or grind their teeth during sleep (sleep bruxism) have no idea it is happening until they wake up with a sore jaw, a dull morning temple headache, or a sudden sharp zing when biting down on a cracked molar. While normal daytime chewing places roughly 20 to 40 pounds of pressure on your back teeth, unconscious nighttime clenching and grinding can generate up to 250 pounds of lateral force without your brain’s normal protective reflexes to stop it.
At Mountainside Family Dentistry in Southeast Portland (3740 SE 122nd Ave), Dr. Anthony El Youssef, Dr. Raphael Joseph, and Dr. Aziz Azar design custom, digitally scanned occlusal nightguards that act as a precision shock absorber between your upper and lower teeth. Using our putty-free 3D intraoral optical scanner, we craft slim, comfortable guards that stop enamel flattening, prevent worn notches along the gumline (paired with tooth-colored composite fillings), relieve TMJ jaw tension, and safeguard your same-day CEREC® Zirconia crowns and dental implants.

Why Patients Choose a Custom 3D-Scanned Nightguard Over a Store-Bought Guard
4 Warning Signs You Are Clenching or Grinding Your Teeth at Night
Because nighttime bruxism happens during deep sleep transitions, most patients only discover they grind when a partner hears it or when their teeth begin showing structural signs of overload:
1. Sensitive Worn Notches Along the Gumline
When heavy lateral grinding forces push back and forth on your premolars and molars, the tooth bends microscopically at its narrowest neck right at the gumline. Over time, enamel prisms pop off at the gumline, leaving a V-shaped notch that zings with cold water or toothbrush bristles (repaired with bonded tooth-colored fillings and protected from returning with a nightguard).
2. Flattened Chewing Cusps & Chipped Front Edges
Healthy teeth have rounded, contoured cusps and smooth incisal edges. Chronic grinding wears through the white outer enamel like sandpaper, exposing flat yellow craters of softer inner dentin that wear down 7 times faster than enamel and make front teeth look shorter, translucent, or chipped.
3. Cracked Molars & Fractured Fillings
Vertical hairline craze lines in your molars—especially around older fillings—can deepen under nighttime clenching until a cusp fractures or the tooth hurts sharply when releasing your bite (Cracked Tooth Syndrome), requiring a full-coverage same-day CEREC® Zirconia crown.
4. Morning Jaw Tightness, Clicking TMJ & Temple Headaches
Clenching for hours overnight exhausts the powerful masseter and temporalis muscles and compresses the shock-absorbing cartilage disc inside your temporomandibular joint (TMJ), causing stiff jaws at breakfast, ear-area soreness, jaw clicking, and tension headaches.
How We Craft Your Custom Nightguard in 4 Simple Steps
Getting a custom nightguard at Mountainside Family Dentistry is fast, comfortable, and completely free of messy impression putty:
1. Bite, TMJ & Enamel Wear Evaluation
Your dentist examines your chewing surfaces, gumline necks, existing crowns or fillings, and TMJ jaw joint mobility to determine whether a dual-laminate (hard/soft), all-hard acrylic, or specialized anterior deprogrammer guard best fits your bite pattern.
2. Putty-Free 3D Optical Intraoral Scan
Instead of biting into trays of goopy alginate putty, we glide a compact 3D optical camera wand across your upper and lower teeth for 2 minutes, recording a micron-accurate digital model of your arches and natural bite relationship.
3. Precision CAD/CAM Guard Fabrication
Your digital scan is used to fabricate a slim, crystal-clear, BPA-free medical-grade nightguard contoured to snap snugly over your teeth (typically the upper arch) with a balanced, flat occlusal bite plane that prevents back molars from locking together.
4. Custom Bite Calibration & Delivery
At your quick delivery visit, we verify that your nightguard seats with gentle, even retention, check your bite contacts with ultra-thin articulating paper so every tooth touches evenly, and provide a ventilated storage case and easy cleaning instructions.
Custom Dental Nightguard vs. Over-the-Counter “Boil-and-Bite” Pharmacy Guards
Patients often ask why an over-the-counter rubber guard from the drugstore cannot replace a custom dental occlusal guard:
Why Soft Pharmacy Guards Can Actually Increase Clenching
Over-the-counter boil-and-bite guards are made of thick, spongy, chewy rubber that is not calibrated to your bite hinge. To a sleeping brain, a thick rubbery material between the teeth feels like food—triggering a subconscious “chewing toy” reflex that can make your jaw muscles clench even harder overnight and worsen morning TMJ soreness.
How a Balanced Occlusal Splint Quiets Jaw Muscles
Our custom dual-laminate nightguards combine a comfortable inner liner with a smooth, hard outer acrylic surface calibrated to your exact bite plane. Instead of catching on steep molar cusps or giving your jaw something spongy to chew on, opposing teeth glide friction-free across the smooth surface—signaling your jaw muscles to relax and protecting your teeth for years.
🩺 Just Had New Crowns, Veneers, Implants, or Gumline Fillings Placed?
If you have invested in same-day CEREC® Zirconia crowns, porcelain veneers, dental implants, or tooth-colored gumline fillings, a custom nightguard is the single best insurance policy for your restorations. Unlike natural teeth, which have a microscopic shock-absorbing ligament (the periodontal ligament) that lets the root give slightly under pressure, a dental implant is fused solidly to bone. Wearing a custom nightguard cushions both your restorations and the opposing natural teeth against nighttime overload. (And if you already own a nightguard, always bring it with you when getting a new filling or crown so our doctors can adjust the inside of your guard to fit your new restoration!)
Frequently Asked Questions About Custom Dental Nightguards
Does a custom nightguard go on my top teeth or bottom teeth?
Because your upper and lower teeth meet together when you clench, wearing a nightguard on one arch (most commonly the upper arch) protects both your top and bottom teeth simultaneously! We occasionally design a lower nightguard if a patient has a sensitive gag reflex or specific front-tooth crowding that makes a lower guard more comfortable.
How do I clean and care for my nightguard each morning?
Each morning when you take your nightguard out, rinse it with cool or lukewarm water and gently brush it with a soft toothbrush and a drop of mild clear dish soap or non-abrasive hand soap (avoid gritty whitening toothpaste, which can scratch the clear acrylic). Let it air-dry in its ventilated case away from pets, and NEVER place it in boiling or hot water, which can warp the custom fit.
Will my dental insurance cover a custom occlusal nightguard?
Many dental insurance plans include benefits for a custom occlusal guard (CDT code D9944 / D9945) when there is clinical evidence of bruxism, tooth wear, or TMJ symptoms, while other plans classify guards as an optional benefit. Our team always checks your specific insurance coverage up front and gives you a clear, transparent breakdown before taking your 3D scan.
Can I use a nightguard as a sports mouthguard?
No—a nightguard and an athletic sports mouthguard are engineered for two completely different jobs. A nightguard is a slim, firm occlusal splint designed to let opposing teeth slide smoothly during sleep without locking the jaw. A sports mouthguard is made of thicker, shock-absorbing EVA material that wraps high over the front gums to protect against sudden external impacts from balls, elbows, or falls.
