Do you wake up with a sore jaw, a dull headache, or teeth that feel strangely sensitive? You might be grinding your teeth — and you may not even realize it. Teeth grinding, clinically known as bruxism, is one of the most common and overlooked dental issues patients bring to Northridge Dentistry & Implants and Dr. Kevin H. Gropp.
Most people grind while they sleep, which makes it hard to catch without knowing the warning signs. Below are five signs that you might be grinding your teeth, plus practical steps you can take. If any of these sound familiar, contact the Northridge office at (818) 709-8645.
1. You wake up with jaw pain or soreness
One of the most telltale signs of nighttime bruxism is waking up with a tight, aching jaw. If your jaw muscles feel fatigued first thing in the morning — almost like you’ve been clenching all night — there’s a good chance you have been. Over time, constant muscle engagement can contribute to temporomandibular joint problems (TMJ/TMD), with chronic jaw pain, clicking, or limited range of motion.
2. You have frequent morning headaches
Headaches that show up right after you wake up — especially around the temples or the back of the head — are a classic bruxism symptom. Sustained clenching overnight puts significant stress on the muscles of your head and neck. If you’re reaching for a pain reliever before coffee more often than not, it’s worth mentioning at your next dental visit.
3. Your teeth look worn, chipped, or flat
Healthy teeth naturally have cusps, ridges, and contours. If your teeth look unusually flat, shorter than they used to be, or you’re noticing small chips that seem to appear out of nowhere, grinding may be the culprit. Enamel is extremely hard, but repeated grinding force can wear it down. Once enamel is gone, it does not grow back — so early detection matters.
4. You’re experiencing increased tooth sensitivity
Have hot coffee or cold ice cream started to feel more intense than usual? Worn enamel can expose more sensitive inner layers, making everyday foods and drinks uncomfortable. Many patients assume sensitivity is “just aging,” but it can also be a direct result of grinding that is stripping enamel.
5. Your sleep partner has heard you grinding
Nighttime grinding can be loud enough for someone nearby to hear — often described as a scraping or squeaking sound. If your partner has nudged you awake or mentioned the noise in the morning, take it seriously. You may be grinding with far more force than you’d expect.
What you can do about bruxism
The good news: bruxism is very treatable when caught early. At Northridge Dentistry & Implants, Dr. Kevin H. Gropp can help evaluate your symptoms and recommend options such as:
- Custom night guards — a professionally fitted guard is one of the most effective ways to protect teeth from grinding damage while you sleep. Custom fit generally offers better comfort and protection than over-the-counter versions.
- Stress management — stress and anxiety are common triggers; mindfulness, therapy, or lifestyle changes can meaningfully reduce grinding for some people.
- Bite evaluation — an uneven or misaligned bite can contribute to grinding; your dentist can assess whether alignment-related treatment is appropriate.
- Restorative care — if grinding has already caused visible damage, options such as bonding, crowns, or veneers may help repair and protect affected teeth.
Take action before damage adds up
Bruxism rarely causes dramatic pain overnight. It builds gradually, quietly wearing teeth and straining the jaw over months or years. If you recognize any of the signs above, schedule a dental exam so the team can help you get ahead of the problem.
