The Complete Guide to Night Guards: Protecting Your Teeth While You Sleep

A night guard is a custom-fitted dental appliance you wear while sleeping to protect your teeth from grinding and clenching. If you wake up with jaw pain, headaches, or notice your teeth becoming worn down, a night guard can prevent further damage and provide relief from these symptoms. These protective devices work by creating a cushioning barrier between your upper and lower teeth.

At Colonia Dental Associates, Dr. Singh and Dr. Apratim provide custom night guards to help patients throughout Woodbridge, Colonia, and the surrounding areas protect their smiles from the effects of nighttime teeth grinding. Our general dentistry services include comprehensive solutions for preventing and treating the consequences of bruxism.

What Causes Teeth Grinding at Night?

Teeth grinding and clenching, medically known as bruxism, happens for several reasons. Stress and anxiety are the most common triggers, as tension accumulates throughout the day and manifests during sleep. Sleep disorders like sleep apnea can also contribute to grinding, as your body struggles to maintain proper breathing patterns. Other factors include misaligned teeth, an abnormal bite, or missing teeth, creating an uneven surface when your jaws close.

Certain medications, particularly some antidepressants, can increase the likelihood of grinding. Lifestyle habits such as excessive caffeine consumption, alcohol use, and smoking have also been linked to bruxism. Research from the American Dental Association indicates over 70% of dentists observed increased signs of teeth grinding in patients during a 2021 survey, suggesting stress-related grinding has become more prevalent in recent years.

Signs You Need a Night Guard

Many people grind their teeth without realizing it until damage becomes visible. Recognizing the warning signs early can help you protect your teeth before serious harm occurs.

Common symptoms include:

• Waking with a sore jaw or facial muscles,
• Frequent morning headaches, especially around the temples, and
• Grinding sounds during the night, your partner might notice.

Physical changes to your teeth include flattened, fractured, or chipped tooth surfaces. You might develop increased tooth sensitivity to hot or cold foods and beverages as the protective enamel wears away. Indentations along the inside of your cheeks or tongue, caused by pressing them against your teeth, are also common indicators. If you notice any of these symptoms, schedule a consultation to determine whether a night guard could help protect your teeth.

How Night Guards Protect Your Teeth

Night guards create a physical barrier between your upper and lower teeth, preventing direct contact during grinding episodes. This barrier absorbs and distributes the force of clenching across the guard’s surface rather than concentrating it on individual teeth. By doing so, they prevent the gradual wearing down of tooth enamel, the hardest substance in your body, but still vulnerable to repeated grinding forces.

The protective appliance also helps reduce muscle tension in your jaw. When you wear a night guard, your jaw muscles often relax because they encounter resistance rather than the hard surface of opposing teeth. This can decrease the intensity of grinding episodes over time. Night guards maintain proper spacing between your jaws, preventing excessive pressure on your temporomandibular joint. This spacing helps minimize jaw pain, clicking sounds, and the risk of developing TMJ disorders.

The Custom Fitting Process

Getting a custom night guard starts with a thorough dental examination. Your dentist will assess your teeth for signs of grinding damage, check your bite alignment, and evaluate your jaw function. This examination helps determine which type of night guard will work best for your specific situation.

The next step involves taking detailed impressions of your teeth. These impressions capture the exact shape and position of your teeth, ensuring your night guard fits perfectly. The impressions are sent to a dental laboratory where skilled technicians fabricate your custom guard. This process typically takes one to two weeks. Once your night guard is ready, you’ll return for a fitting appointment where your dentist will check the fit, make any necessary adjustments, and show you how to properly insert and remove the guard.

Caring for Your Night Guard

Proper maintenance extends the life of your night guard and keeps it hygienic. Rinse your guard with cool water immediately after removing it each morning. Use a soft toothbrush and mild soap or denture cleaner to gently clean all surfaces. Avoid hot water, which can warp the material and alter the fit. Store your night guard in its protective case when not in use to prevent damage and contamination while allowing proper air circulation to keep it dry.

Deep clean your night guard weekly using a denture cleaning tablet or a mixture of equal parts water and white vinegar. Let it soak for about 30 minutes, then rinse thoroughly. Bring your night guard to your regular dental checkups so your dentist can inspect it for signs of wear or damage. Most custom night guards last between one and five years with proper care, though this varies based on grinding severity and maintenance habits.

When to Replace Your Night Guard

Even with excellent care, night guards don’t last forever. Visible signs of wear include holes, tears, or thin spots in the material. If your night guard becomes loose or no longer fits snugly, it’s no longer providing adequate protection. Cracks or fractures, even small ones, compromise the guard’s structural integrity and require replacement.

Changes in your dental work also necessitate a new night guard. If you get dental veneers, crowns, bridges, or have teeth extracted, your old guard won’t fit properly. Schedule an appointment to have a new impression taken and a replacement guard made.
