Night guard for grinding: when I recommend one, and when I don’t.

Looking for a night guard for grinding in Irvine? At mend dental, I recommend a custom night guard when clenching or grinding is wearing enamel, stressing fillings, or leaving your jaw sore, and I do not treat it as an automatic add-on for every adult.

Custom night guard on a clean tray at mend dental

A guard protects teeth overnight. It does not fix an uneven bite, active gum disease, or a tooth that already needs a crown.

What grinding does overnight

Clenching and grinding put heavy load on enamel and on old fillings. Over time teeth can look shorter or sharper, fillings can crack, and jaw muscles stay tight in the morning.

At a checkup I look for wear facets, cracked cusps, and bitten-through restorations. Digital X-rays and a 3D scan help us see damage you cannot feel yet.

When a custom night guard helps

  • Wear or cracks point to nighttime grinding
  • You wake with jaw tension and your teeth show matching wear
  • We have restored a tooth that still needs protection from grinding forces

We scan digitally so the guard fits your bite precisely. Store-bought boil-and-bite trays are softer and less accurate. I would rather fit one that holds up than sell you something that does not protect the teeth that need it.

When I look past the guard first

  • A crack or large failing filling needs a crown or onlay before protection will help
  • Gum disease or decay should be treated first
  • The bite is so uneven that we need to understand contact points before hard appliance wear
  • Stress, sleep, or airway concerns dominate the story and need the right medical partner alongside dental protection

I will say when a guard alone is not enough. Protection without fixing a failing tooth just delays the break.

What the appointment looks like

Exam and imaging first. If a custom guard is appropriate, we take a digital scan, the lab makes it, and we check the fit and bite when it arrives. You get clear instructions on wear and cleaning.

Price and insurance vary by plan. We verify benefits and give a written estimate before you commit.

Sore jaw or worn teeth?

Call (949) 251-0011 and we will look before we recommend anything. Details on fit and care are on our night guards page.

Quick answers

Morning jaw tension, teeth that look shorter or sharper, cracked fillings, or wear facets we see at your exam. Many people do not know until we show them.

Boil-and-bite trays are softer and less accurate. A custom guard scanned to your bite protects better and lasts longer.

No. A crack or failing filling needs a crown or onlay first. The guard protects the repair afterward.

It varies by plan. We verify benefits and give a written estimate before you commit.
