Waking up with a dull headache or a sore jaw isn’t just an annoying way to start the day. It is often a sign of a common, yet frequently overlooked, dental issue: bruxism.

Bruxism is the medical term for grinding or clenching your teeth. While some people do this during the day when stressed, many do it unconsciously while they sleep. Over time, this nocturnal habit can wreak havoc on your dental health, causing significant tooth wear, fractures, and chronic pain.

If you suspect you might be grinding your teeth, you are not alone, and there is a simple solution. At Lighthouse Dental Practice, we often recommend custom night guards as a preventative measure to safeguard your smile while you rest.

Understanding Bruxism: Why We Grind

Teeth grinding is a complex condition with various potential causes. It is rarely triggered by a single factor but rather a combination of physical, psychological, and lifestyle elements.

Stress and Anxiety

The most common cause of bruxism is stress. When we are anxious, our bodies hold tension, and for many, that tension manifests in the jaw muscles. Even if you feel relaxed before bed, your subconscious mind might be processing the day’s worries, leading to intense clenching throughout the night.

Sleep Disorders

There is a strong link between bruxism and sleep disorders, particularly Obstructive Sleep Apnoea (OSA). When breathing is interrupted during sleep, the body may respond by moving the jaw or grinding teeth to reopen the airway. If you snore loudly or wake up gasping for air, your teeth grinding might be a symptom of this broader respiratory issue.

Lifestyle Factors

Certain substances can increase the likelihood of grinding. High consumption of caffeine or alcohol, smoking, and certain medications (particularly antidepressants) are known to exacerbate the condition.

Misaligned Teeth

Sometimes, the cause is purely mechanical. If your top and bottom teeth do not fit together smoothly (malocclusion), your jaw muscles may work overtime trying to find a comfortable resting position, resulting in grinding.

The Consequences of Ignoring Tooth Wear

It is easy to dismiss a bit of jaw stiffness, but ignoring bruxism can lead to expensive and painful dental problems down the road. Your teeth are incredibly strong, but they are not designed to withstand the immense pressure of nightly grinding.

1. Enamel Erosion
   The most immediate effect is the wearing down of tooth enamel. Once this protective outer layer is gone, it cannot grow back. This exposes the sensitive dentin underneath, leading to sharp pain when consuming hot or cold foods and drinks.
2. Flattened or Fractured Teeth
   Chronic grinders often have teeth that look flat or short. The constant friction acts like sandpaper, slowly filing down the natural peaks of your teeth. In severe cases, the pressure can cause teeth to crack, chip, or fracture entirely, requiring crowns, root canals, or even extraction.
3. TMJ Disorders
   The temporomandibular joint (TMJ) connects your jaw to your skull. Constant clenching puts excessive strain on this joint, leading to inflammation, clicking or popping sounds, and difficulty opening or closing your mouth.
4. Chronic Headaches
   The tension in your jaw muscles can radiate upwards, causing tension headaches that typically present in the morning. It can also cause referred pain in the ears, face, and neck.

How a Night Guard Helps

Think of a night guard as a safety barrier for your teeth. It is a removable appliance, typically made of durable plastic, that fits over your upper or lower teeth.

The primary function of a night guard is to absorb the force of clenching. Instead of your top and bottom teeth grinding against each other—enamel on enamel—they glide against the protective material of the guard. This prevents wear and tear, reduces muscle strain, and protects your jaw joint.

While you can purchase over-the-counter “boil-and-bite” guards at pharmacies, they are rarely the best solution for long-term use.

The “Boil-and-Bite” vs. Custom Night Guards

When it comes to protecting your dental health, precision matters.

Store-Bought Guards:
These generic guards are designed to fit “most” mouths. You boil them in water and bite down to shape them. However, they are often bulky, uncomfortable, and can impede breathing during sleep. Because the fit is not precise, they can sometimes fall out or even encourage more chewing because the brain interprets the soft, ill-fitting rubber as food.

Custom Night Guards from Lighthouse Dental Practice:
A custom guard is fabricated specifically for your mouth. We take a precise impression or digital scan of your teeth, which is then used to create a guard that fits perfectly.

• Comfort: They are slim and unobtrusive, making it easier to sleep.

• Durability: Made from high-quality materials, they last much longer than store-bought alternatives.

• Protection: They are designed to distribute the force of grinding evenly, ensuring maximum protection for your jaw and teeth.

What to Expect at Your Appointment

Getting a custom night guard is a straightforward and painless process.

1. Consultation: During your check-up, we will examine your teeth for signs of wear and discuss your symptoms. We will also check your jaw muscles and joints.

1. Impressions: If we determine a night guard is right for you, we will take impressions or a 3D scan of your teeth.

1. Fabrication: These measurements are sent to a dental laboratory where your custom guard is crafted.

1. Fitting: Once your guard is ready, you will return to the practice. We will check the fit, make any necessary small adjustments, and show you how to care for it.

Caring for Your Night Guard

To keep your night guard clean and effective, simple maintenance is required:

• Rinse it with cool water immediately after wearing.

• Brush it gently with a toothbrush (but avoid abrasive toothpaste).

• Store it in its perforated case to let it dry and prevent bacterial growth.

• Bring it to your regular dental check-ups so we can inspect it for wear.

Safeguard Your Smile Tonight

Your sleep should be restorative, not destructive. If you are waking up in pain or have noticed changes in the shape of your teeth, do not wait until a tooth cracks to seek help.

A custom night guard is an investment in the longevity of your smile. It offers a simple, non-invasive way to stop the damage of bruxism in its tracks, allowing you to wake up refreshed and pain-free.

Frequently Asked Questions

Can a night guard cure bruxism?

A night guard does not “cure” bruxism in the sense that it stops you from clenching. However, it manages the condition effectively by preventing damage to the teeth and reducing strain on the jaw muscles. Addressing underlying causes, such as stress or sleep apnoea, may help reduce the frequency of grinding.

Is it hard to sleep with a night guard?

Most patients adjust to their custom night guard within a few nights. Because custom guards are made to fit your specific bite, they are significantly more comfortable and less bulky than over-the-counter options.

How long does a custom night guard last?

The lifespan of a night guard depends on the severity of your grinding. Heavy grinders may need a replacement every 1-3 years, while others may find their guard lasts for 5 years or more. We will check the condition of your guard at your regular check-ups.

Can children wear night guards?

Children often grind their teeth, but because their jaws are still growing and they are losing baby teeth, custom hard night guards are not always recommended. In many cases, children outgrow bruxism. However, if you are concerned about your child’s teeth, please bring them in for a consultation so we can monitor the situation.
