Night Guards in San Antonio TX

Custom night guards for teeth grinding in San Antonio's Medical Center District, with Dr. Chris Cappetta, DDS, a member of the Academy of General Dentistry with over 35 years of experience.

Your Teeth Are Grinding Down While You Sleep

Most people who grind their teeth have no idea they are doing it. Bruxism happens during sleep, which means the patient wakes up with a sore jaw or a dull headache while enamel quietly wears away night after night. Patients from Castle Hills and Balcones Heights trust Fountain of Youth Dental for their general dentistry care because Dr. Cappetta, DDS, a member of the Academy of General Dentistry with over 35 years of general dentistry experience, identifies the signs of grinding at routine exams and fits custom night guards before the damage becomes irreversible.

Over time, the force of nighttime grinding flattens cusps, fractures enamel, cracks existing restorations, and wears teeth down to the point where crowns or veneers become necessary to restore what was lost. A custom night guard does not stop the grinding reflex. It redirects the force onto a replaceable appliance instead of onto the tooth surfaces.

What Causes Bruxism and Who Is at Risk

Bruxism is driven by a combination of factors. Stress and anxiety are the most commonly cited contributors. Sleep disorders including sleep apnea are strongly associated with nighttime grinding, which is why Dr. Cappetta screens patients for both conditions when bruxism is identified at an exam.

Other contributing factors include certain medications, particularly SSRIs, caffeine and alcohol consumption before sleep, bite misalignment, and genetic predisposition. Patients who wake with sore jaw muscles, notice their teeth look flatter than they used to, or have a partner who reports hearing grinding during the night are strong candidates for a custom night guard evaluation.

What Grinding Damage Looks Like Over Time

The earliest visible signs of bruxism are flattened cusp tips on the back molars and a slightly translucent or chipped appearance at the edges of the front teeth where enamel has thinned. Patients often attribute these changes to normal aging and do not connect them to nighttime grinding.

As bruxism progresses untreated, existing fillings crack, crowns fracture, and teeth develop temperature sensitivity because the enamel insulating the nerve has worn through. In advanced cases the vertical dimension of the bite collapses as the back teeth wear down, changing the appearance of the face and jaw position. Catching bruxism early with a custom night guard is significantly less expensive than restoring the damage after years of accumulation.

How Dr. Cappetta Fits a Custom Night Guard

Getting a custom night guard at Fountain of Youth Dental starts with an exam. Dr. Cappetta evaluates the grinding damage, assesses your bite, and checks for airway clues like snoring. He then takes impressions so the guard is shaped to fit your teeth.

When the guard is ready, it’s adjusted so your bite feels even when you close. Dr. Cappetta also reviews how to wear it and care for it. Many people need a few nights to get used to it, and a guard that stays sore needs an adjustment rather than more nights of pushing through.

Night Guards in San Antonio, TX

Can a Night Guard Make Sleep Apnea Worse?

For some people it can, which is why the airway question comes first. A 2004 sleep lab study fitted 10 adults with sleep apnea with a flat upper guard. On the guard night, breathing pauses rose by more than half in 5 of them. The study was small, and the group average didn’t change significantly. NIH clinical guidance still lists sleep apnea as a reason to avoid a flat guard.

In Dr. Cappetta’s experience, grinding often traces back to the airway. The jaw works forward at night to keep breathing open, and the teeth take the wear. That changes which guard makes sense. A flat guard shields enamel and does nothing for the airway, while a forward-holding guard may help both. So if you snore and your teeth show wear, the breathing question gets answered before any guard is made.

Custom Night Guard vs Over-the-Counter Guard

Over-the-counter boil-and-bite guards are available at pharmacies and seem like a convenient lower-cost alternative. For patients with mild occasional grinding they provide some protection. For patients with moderate to severe bruxism they fall short in ways that matter clinically.

Custom Night Guard Over-the-Counter Guard
Fit Fabricated to exact impressions of your teeth One-size or boil-and-bite approximation
Bite accuracy Checked by your dentist Not checked by anyone
Durability Hard acrylic that holds up to grinding Soft plastic that wears faster
Comfort Adjusted so your bite feels even Shaped by biting into softened plastic
Protection level Hard acrylic, which works better than soft guards Soft plastic, which can raise clenching in some people
Cost over time Higher upfront Lower upfront

Dr. Cappetta recommends custom night guards for patients with documented bruxism because an ill-fitting appliance that shifts the bite can create new problems while solving the one it was designed to address. Protecting worn teeth usually costs less than rebuilding them later, though every case and plan varies.

How to Care for Your Night Guard

Rinse the guard with cool water immediately after removing it each morning, then clean it with a soft toothbrush and mild liquid soap. Never use hot water or toothpaste. Hot water warps the material and distorts the fit. Toothpaste is abrasive enough to scratch the surface, creating grooves where bacteria build up over time.

Store the guard in the ventilated case provided at delivery so it dries completely between uses. Bring it to every checkup so Dr. Cappetta can assess fit and wear. When the material is bitten through or no longer seats correctly, replacement is the right call.

Frequently Asked Questions

How do I know if I need a night guard?

The most reliable way to know is a dental exam, since most people grind without realizing it. The American Dental Association lists jaw pain, dull headaches, and sore ears or neck as signs you might be grinding. A partner who hears grinding at night is another strong clue. If any of these sound familiar, bring them up at your next visit.

How do I stop myself grinding my teeth?

Start with the clenching you can catch while awake. Cleveland Clinic notes that awake grinding often eases with more awareness and less stress, through steps like exercise, meditation, or cognitive behavioral therapy. Cutting back on caffeine and alcohol in the evening helps too. Sleep grinding is much harder to stop on your own, which is where a guard protects your teeth.

What medication stops teeth grinding?

No pill reliably does. NIH clinical guidance on bruxism management rates the evidence for drugs like clonazepam and clonidine as too limited. It doesn’t recommend them for routine use. Botox injections every 6 months can weaken the jaw muscles in severe cases, but they don’t reduce how often grinding happens. Any medication decision belongs with your physician.

Can teeth be fixed from grinding?

Often, though the repair depends on how much tooth is gone. Mayo Clinic explains that a dentist may reshape chewing surfaces or place crowns once wear causes problems. Sensitivity and trouble chewing are the usual triggers. Repairs last longer when the grinding is controlled first, since the same force will wear new work too. Outcomes vary by person and by tooth.
