Most people who grind their teeth have no idea they do it. It happens at night, it does not wake you, and the first sign is usually something that seems unrelated. A headache at the temples most mornings. A jaw that feels tired before you have eaten anything. A tooth that suddenly goes sensitive to cold. A partner who mentions the noise.
Teeth grinding, called bruxism, is one of the most common things we spot at checkups in Leesburg, and it is one of the easiest to do something about once it is found.
How we know you are grinding before you do
Enamel keeps a record. When we look at a mouth that grinds, we see patterns that do not come from chewing:
- Flattened, even wear across the biting surfaces, especially the canines, which should stay pointed.
- Small chips along the edges of the front teeth, giving them a ragged rather than a rounded line.
- Notches at the gumline, called abfractions, where flexing under pressure has fractured enamel away.
- Hairline cracks running down a molar, sometimes visible only with magnification.
- A scalloped tongue or a ridge along the inside of the cheek, from pressing against teeth.
- Teeth that have become sensitive as worn enamel exposes the softer dentin underneath.
None of that is guesswork or upselling. It is a physical pattern, and we will show you exactly what we are seeing in your own mouth.
Bruxism and TMJ pain are related, but not the same thing
Your temporomandibular joint, the TMJ, is the hinge just in front of each ear that lets your jaw open, close, and slide side to side. It is one of the busiest joints in the body.
Clenching and grinding load that joint and the muscles around it for hours at a stretch. Over time that can produce the cluster of symptoms people call TMJ or TMD: jaw soreness, clicking or popping when you open, a jaw that catches or locks, aching that spreads into the ear, temples, or neck, and tension headaches that are worst in the morning.
Grinding is not the only cause of TMJ pain, and not everyone who grinds develops it. But the two travel together often enough that if you have morning headaches and a sore jaw, grinding is the first thing worth ruling in or out.
Why you grind in the first place
Stress is the reason everyone knows about, and it is real. Bruxism reliably spikes during stressful stretches. But it is not the only driver.
An uneven bite matters, because if teeth do not meet cleanly, the jaw hunts for a comfortable position all night. Some medications, particularly certain antidepressants, list bruxism as a side effect. Caffeine, alcohol, and nicotine all increase nighttime muscle activity.
And there is an important overlap with breathing. Grinding is strongly associated with sleep apnea, because clenching and thrusting the jaw forward can be the body’s attempt to reopen a collapsing airway. If you grind and you also snore, wake unrefreshed, or feel sleepy through the day, the grinding may be a symptom rather than the root problem. Our article on snoring, sleep apnea, and oral appliance therapy covers that connection, and it is worth reading before you buy a guard.
Custom night guard versus the drugstore version
You can buy a boil-and-bite mouth guard for about twenty dollars. It is better than nothing in an emergency, and it is not what we recommend for nightly use.
A store guard is soft and bulky. Soft material tends to invite chewing rather than discourage it, so some people clench harder against it. Bulk pushes the jaw into a position it did not choose. And because it does not fit precisely, it can allow teeth to shift over months of wear, which is a genuinely expensive way to save money on a guard.
A custom night guard is made from an impression or digital scan of your actual teeth. It is thin, it fits one way only, it distributes force evenly across the arch rather than concentrating it on a few teeth, and it is built from a material chosen for your case, harder for heavy grinders and softer for light clenchers. It also lasts years rather than months.
We make custom nightguards here as part of our orthodontics and bite care services. The process is two short visits: one to scan and check the bite, one to fit and adjust.
What a night guard does and does not do
Be clear on this, because it matters.
A night guard protects your teeth. It puts a replaceable layer between the upper and lower arches so the guard takes the wear instead of the enamel. For most patients it also relaxes the muscles enough to reduce morning headaches and jaw soreness noticeably within a few weeks.
A night guard does not stop you grinding. The habit is neurological and it continues. That is fine, because the goal is to make it harmless rather than to eliminate it.
What grinding costs if you ignore it
Enamel does not grow back. Once it is worn through, the fix is not a night guard, it is restoration: fillings, crowns, or veneers to rebuild teeth that have lost structure. Cracked teeth can require root canal treatment or extraction. A worn bite can drop the height of the lower face over years, which is a much bigger conversation than a guard.
A custom night guard is one of the least expensive things in dentistry that prevents one of the most expensive outcomes. Most insurance plans cover part of it. Our membership plan applies a discount if you do not have insurance, and financing is available.
Simple things to try alongside a guard
Cut caffeine after midday. Keep alcohol away from bedtime, since it deepens muscle activity. Notice your daytime posture, because a lot of clenching happens at a desk with teeth touching, and teeth at rest should be slightly apart. Warm compresses on the jaw muscles before bed help many people. And if stress is the driver, treat the stress, not just the symptom.

If you wake up with a sore jaw, if your headaches are worst in the morning, if a partner has mentioned grinding, or if your front teeth are looking shorter than they used to, that is worth an exam.
