Nightguards for Teeth Grinding: Signs You May Need One and How They Help

Jul 2, 2026

Teeth grinding, also called bruxism, often happens during sleep. Many people do not realize they are grinding or clenching until a dentist notices worn enamel, small chips, jaw tension, or other signs during a dental exam.

A custom nightguard can help protect your teeth from the pressure of grinding and clenching. At Gardena Family Dental, nightguards are used as a preventive option to reduce damage, improve comfort, and support long-term oral health.

What Is a Nightguard?

A nightguard is a dental appliance worn while you sleep. It creates a protective barrier between your upper and lower teeth, helping reduce the impact of grinding and clenching.

Unlike over-the-counter guards, a custom nightguard is made to fit your mouth more comfortably and securely. This can make it easier to wear consistently and may provide better protection over time.

Signs You May Be Grinding Your Teeth

Because teeth grinding often happens at night, the symptoms can be easy to miss. Common signs include:

Jaw soreness or tightness in the morning
Frequent headaches
Worn, chipped, or flattened teeth
Tooth sensitivity
Pain while chewing
Clicking or discomfort in the jaw
A partner noticing grinding sounds during sleep

If you have any of these symptoms, a dental exam can help determine whether grinding may be affecting your teeth.

How Nightguards Help Protect Your Smile

Nightguards do not stop every cause of grinding, but they can help reduce the damage it causes. By cushioning the teeth, a nightguard helps protect enamel, dental fillings, crowns, and other restorations from excess pressure.

This protection can lower the risk of cracks, chips, sensitivity, and uneven wear. It may also help reduce muscle strain caused by clenching.

For patients who already have restorative dental work, a nightguard can be especially helpful in protecting that investment.

When to Talk to Your Dentist

If you wake up with jaw pain, notice tooth sensitivity, or see changes in the shape of your teeth, it may be time to ask about a nightguard. Your dentist can examine your bite, check for signs of wear, and recommend the right option for your needs.

Protect Your Teeth While You Sleep

Teeth grinding can cause long-term damage when left untreated. A custom nightguard offers a simple, comfortable way to protect your smile while you rest.
