Are You Grinding Through Summer? What Bruxism Is Really Doing to Your Teeth — and How to Stop It

Most people who grind their teeth have no idea it’s happening. It occurs during sleep, leaves no obvious clues in the moment, and tends to develop gradually enough that the symptoms get attributed to other things. A headache that appears every few mornings becomes just part of the week. Jaw soreness on waking gets blamed on a stiff pillow. Tooth sensitivity that wasn’t there a year ago gets chalked up to age.

By the time a patient at Rivers + West Family Dentistry in Mount Pleasant sits in the chair and learns for the first time that they’ve been grinding, the evidence is already visible in the enamel. The wear patterns don’t lie — and once enamel is gone, it doesn’t come back.

The good news is that bruxism is highly manageable when it’s identified and addressed. And June — when routines shift, travel ramps up, and sleep patterns tend to go slightly sideways — is actually one of the most relevant times of year to understand what bruxism is, whether you might have it, and what to do about it.

What Bruxism Is and Why It Happens

Bruxism is the clinical term for the unconscious clenching or grinding of teeth, most commonly occurring during sleep. The jaw muscles are capable of generating enormous force — far more than the controlled, purposeful force of normal chewing. During a grinding episode, teeth make sustained or repetitive contact under this elevated load, abrading the enamel surfaces with each cycle.

The exact causes of bruxism aren’t fully understood, but several factors are consistently associated with it. Psychological stress is the most significant driver — the jaw is one of the places where the body unconsciously holds tension, and higher-stress periods tend to produce more intense bruxism episodes. Sleep architecture plays a role as well, with grinding often occurring during lighter stages of sleep and correlating with conditions like sleep apnea. Certain medications, caffeine intake, and alcohol consumption have also been linked to higher rates of nocturnal bruxism.

Summertime introduces a specific set of bruxism triggers. Travel across time zones disrupts sleep patterns. Irregular schedules associated with vacations or out-of-town guests create stress of their own, even when the stress is technically positive. Social obligations, heat affecting sleep quality, and changes in alcohol consumption patterns during summer entertaining all create conditions where bruxism tends to worsen for patients already prone to it.

The Damage Bruxism Does — and Why It Compounds

Enamel is the hardest substance in the human body, but it is not self-repairing. The body cannot regenerate enamel once it’s been worn away. This means that every night of unmanaged grinding represents permanent, cumulative loss that alters the teeth in ways that eventually require restorative intervention.

The progression of bruxism damage tends to follow a predictable pattern. In early stages, wear is visible on the biting surfaces of the teeth — particularly the canines and molars — and patients may notice increased sensitivity to temperature changes. As wear continues, teeth shorten. The once-distinct biting edges become flattened and uniform. The bite relationship begins to change as the vertical dimension of the teeth is reduced, which places additional stress on the jaw joint and muscles.

In advanced cases, teeth fracture. The repeated stress concentration from grinding creates microfractures in the enamel that eventually propagate into cracks — visible lines that can travel into the dentin beneath and, if untreated, into the pulp of the tooth. Teeth that fracture significantly may require crowns or, if the fracture reaches the root, extraction.

Beyond the teeth themselves, chronic bruxism is a primary driver of temporomandibular joint (TMJ) dysfunction. The sustained, elevated load on the joint from nightly grinding damages the disc and surrounding tissues, producing the clicking, limited jaw opening, and facial pain that characterizes TMJ disorder.

How Bruxism Is Identified

Because bruxism occurs during sleep, patients often don’t recognize it themselves. The most common pathway to diagnosis is through a routine dental exam, where the examining dentist identifies the characteristic wear patterns that distinguish grinding damage from normal age-related changes.

Dr. Chris Rivers, a Mount Pleasant native who completed his Doctor of Dental Medicine at the Medical University of South Carolina, and Dr. Kate West, a Clemson graduate who earned her DMD at MUSC and completed a General Practice Residency at Prisma Health, approach every comprehensive exam with attention to these markers. The subtle flattening of cusp tips, the loss of surface anatomy on molars, the presence of scalloping on the tongue or linea alba on the cheeks — these are the physical signs that tell the clinical story.

Patients who come in with unexplained jaw soreness, morning headaches, or tooth sensitivity that doesn’t have an obvious cause are often found, upon examination, to have bruxism as the underlying explanation for all of it.

The Nightguard: What It Does and Why It Works

The primary treatment for bruxism is a custom-fitted nightguard — an oral appliance worn during sleep that creates a physical barrier between the upper and lower teeth. The nightguard does not stop the grinding behavior; the brain’s unconscious drive to clench or grind continues. What the nightguard does is redirect the grinding forces onto a durable, replaceable surface rather than onto the tooth enamel. The appliance absorbs and distributes the load, protecting the teeth from further wear and reducing the mechanical stress transmitted to the jaw joint.

The critical distinction is between a custom-fitted nightguard and an over-the-counter boil-and-bite device. The mass-market alternatives provide some degree of protection but are typically too thick, fit imprecisely, and in some cases can actually make bruxism worse by stimulating more grinding in response to the unfamiliar bulk in the mouth. A well-fitted custom nightguard is made from a precise impression of the patient’s teeth, is fabricated to the correct thickness for their bite, and is designed to distribute force evenly — producing results that the drugstore version simply cannot match.

Summer Is a Practical Time to Address It

For patients who’ve been told they show signs of bruxism at previous appointments and have been meaning to follow through, summer’s somewhat lighter schedule and the availability of dental appointments with less competition from school-year obligations make it a practical window to take action. The nightguard fabrication process involves two relatively brief appointments — one for impressions and one for fitting — and the device is ready to use within a week or two of the initial appointment.

For those who travel frequently in summer, a nightguard is also easily portable and requires no special storage. It travels in a small case, which is considerably more practical than managing bruxism without one while your sleep patterns are already disrupted.

Protect Your Enamel Before More Is Lost

Rivers + West Family Dentistry is independently owned and driven by a simple philosophy: treat patients like family, recommend only what’s genuinely needed, and focus on conservative care that protects natural teeth for as long as possible. A nightguard for a bruxism patient is exactly the kind of preventive intervention that makes expensive restorative treatment less likely down the road.
