Teeth grinding, known medically as bruxism, is surprisingly common, and a lot of people who do it have no idea. Because it usually happens during sleep, the first clues often show up as aches and worn teeth rather than the grinding itself. Left unchecked, nighttime grinding can wear down enamel, crack teeth, and strain the jaw. The good news is that it is very manageable once you recognize it. Here are the signs to watch for and how a custom nightguard can help.
Why grinding goes unnoticed
Most nighttime grinding happens unconsciously, so unless a partner hears it, you may never catch yourself in the act. Instead, your body sends indirect signals. The forces involved in grinding and clenching can be substantial, far more than normal chewing, and they add up night after night. That is why the damage and discomfort tend to build gradually until they become hard to ignore.
Common signs of nighttime grinding
If you grind your teeth at night, you may notice one or more of these:
- A sore or tired jaw, especially in the morning.
- Frequent headaches, often starting near the temples.
- Teeth that are flattened, chipped, or increasingly sensitive.
- Aching or tightness in the face or around the ears.
- A clicking or popping jaw, or trouble opening wide.
- Disrupted sleep, for you or your partner who hears the grinding.
Some people also notice small ridges or indentations along the edge of the tongue or the inside of the cheek, which can be signs of clenching pressure.
What grinding does to your teeth
Over time, grinding wears away the enamel that protects your teeth, which can lead to sensitivity, flattened chewing surfaces, and tiny cracks. It can also chip or loosen existing dental work, including fillings and crowns. In fact, grinding is one of the most common reasons a crown or filling fails earlier than expected. Catching grinding early helps you avoid this kind of cumulative damage.
What causes teeth grinding
Bruxism has several possible contributors. Stress and anxiety are among the most common, but an uneven bite, certain medications, sleep issues, caffeine, and alcohol can all play a role. Because the causes vary, part of addressing grinding is talking through what might be driving it. During a routine exam, Dr. Anna Yi can spot the telltale wear patterns of grinding even before you are sure you do it.
How a nightguard helps
The most effective and straightforward protection is a custom nightguard. Worn over your teeth while you sleep, it cushions the forces of grinding and clenching, protecting your enamel and your dental work from wear and fracture. A custom guard made to fit your mouth is more comfortable and durable than a generic one, which we explain in our comparison of custom vs store-bought nightguards.
