When Your Jaw Aches Before Your Day Even Starts

What Mouth Guards Fix
A dental mouth guard is a soft or firm shield that covers your teeth and sits over your bite, cushioning them from grinding, clenching, or a hit during sports. A custom one starts as a mold of your own teeth, so it’s shaped to fit your mouth exactly, unlike a generic one you’d buy off a shelf.
They’re typically recommended for:
- Grinding or clenching your teeth at night
- Jaw pain, popping, or soreness linked to TMJ
- Teeth that are wearing down or cracking from grinding
- Contact sports or activities with a risk of a blow to the mouth
- Protecting braces during sports or physical activity

⭐️⭐️⭐️⭐️⭐️ I had a fantastic experience at my dental cleaning today! From the moment I walked in, the front desk staff were welcoming, helpful, and made check-in a breeze. The office itself is clean, comfortable, and has a calming atmosphere that immediately put me at ease. The hygienist and dentist had such great bedside manner—friendly, professional, and genuinely caring. They explained everything clearly and made sure I was comfortable throughout the entire visit. It’s rare to find a team that combines excellent care with such outstanding customer service. I left feeling well cared for and grateful to have found a dental office that treats patients like family. Highly recommend!Posted on Google![]()

I’ve been going there for several years. It has been a great experience. They are very careful in the work they do—much better than other dentists I have gone to in the past. I strongly recommend them.Posted on Google![]()

Dr. Davis has been my dentist for years, ever since he took over the practice from Dr. Fong, and I think I've interacted with just about everyone in the office, and they are all INCREDIBLE. Seriously, these are some of the kindest, most professional, totally on the ball people you will ever have the pleasure of visiting for a dental appointment. I'm sad to be leaving the state, because it means I will no longer be able to go to Eastview Family Dental, which is a tragedy. They really are the best!Posted on Google![]()

What to Expect from Your Mouth Guard Process
Consultation & Exam
We check your bite, ask about grinding, jaw pain, or sports needs, and decide whether a night guard, a sports guard, or both fit your situation.
Impressions
We take a mold of your teeth, so your guard is shaped to your bite rather than a generic size.
Custom Fabrication
Your mouth guard is made from that mold, using a material suited to your specific use, softer for grinding, firmer for sports.
Fit Check & Adjustments
Dr. Hedayati checks the fit and makes small adjustments so it feels secure without being tight.
Mouth Guards Cost and Insurance
Cost depends on the type of guard and material used, since a night mouth guard and a sports mouth guard aren’t priced the same. Many dental insurance plans cover a portion of a custom night guard when it’s recommended for a medical reason like grinding, bruxism, or TMJ, though sports guards are typically not covered since they’re elective.
At Kirkland Dental Excellence, we go over your treatment options and estimated cost before anything begins. Call us at (425) 827-2003 to check your benefits. Our practice accepts Premera, Regence, Delta Dental, Cigna, and many more.
