"I have pretty extensive damage from grinding my teeth for years. I’ve cracked three crowns and broken a veneer from teeth grinding. Needless to say, I should have been wearing a night guard a long time ago. Fast forward thousands of dollars later, I found Sentinel through an article online and decided to go for it. No complaints. The guard serves its purpose well. Thanks Sentinel:)"

How It Works

Is a Custom Night Guard for Teeth Grinding the Best Solution For Your Mouth?

Bruxism has many negative impacts. Tooth pain, jaw pain, joint inflammation, teeth erosion and breakage are just a few of the effects of constant teeth grinding and jaw clenching. To date, there is no known cure for bruxism. The only proven relief from the effects of bruxing is to wear a well-fitted custom dental night guard. Over the counter, store bought night guards can present an array of problems including bite issues and worsened bruxism. Luckily, lab-made custom night guards are now accessible and affordable. No multiple dental office visits. No hefty price tag. And delivery right to your door! It doesn’t get much better than that.
