Waking up with a sore jaw, headache, or damaged teeth may be a sign that you are clenching or grinding your teeth during sleep. This common condition, called bruxism, can contribute to tooth wear, jaw discomfort, and related dental issues over time. Effective dental devices, such as bite splints and night guards, can help protect your teeth and manage symptoms of bruxism.
While they may appear similar, a custom-made device worn at night has different purposes and designs. Understanding these differences is important in choosing the option that best suits your needs.
This guide explains the purpose, design, fitting, and care of bite splints and night guards to help you make an informed decision. We also outline which option may be suitable based on your symptoms, to support better sleep and protect your teeth.
What is a Bite Splint?
A bite splint, sometimes called an occlusal splint, is a custom-made dental device used to help manage jaw muscle tension and discomfort. Unlike a basic mouthguard, a bite splint is designed to modify the way the upper and lower teeth meet, thereby reducing muscle strain.
A dentist will create a bite splint tailored to your mouth, ensuring it provides support and guidance for your jaw muscles. Bite splints are usually made from hard acrylic and cover the upper or lower teeth, depending on the treatment plan.
The primary goal is to alleviate strain on the jaw muscles and support the temporomandibular joint (TMJ). This can be especially helpful for individuals experiencing symptoms of temporomandibular joint disorder (TMD), such as jaw soreness or limited jaw movement.
The flat, stable surface allows the jaw muscles to relax, reducing the habitual clenching that can contribute to discomfort. While it also helps protect teeth from grinding, the focus is on managing muscle tension and supporting jaw function.
What is a Night Guard?
A night guard is a dental device designed to protect your teeth from wear caused by clenching or grinding during sleep. It works by creating a barrier between the upper and lower teeth to reduce tooth-to-tooth contact.
Night guards are usually made from a softer, flexible material to absorb grinding forces. Custom-made by a dentist, night guards primarily absorb the forces of grinding to help prevent tooth wear, chipping, or cracks.
The night guard absorbs the pressure from clenching or grinding, reducing strain on the teeth. This prevents direct contact between teeth, helping to preserve enamel and dental structures.
Night guards are available over the counter or custom-made by a dentist, with the latter providing a better fit and protection. Custom night guards offer enhanced comfort and protection, as they are specifically designed to fit your teeth.
Differences Between Bite Splints and Night Guards
While both devices are worn in the mouth at night to help with jaw issues, their key differences lie in their purpose, material, and design.
Purpose
- Bite Splint: Corrects the underlying jaw position and muscle tension. It’s a therapeutic device for TMD and chronic jaw pain.
- Night Guard: Protects teeth from the physical damage of grinding and clenching. It’s a protective shield.
Material
- Bite Splint: Usually made from a hard, rigid acrylic. This material is essential for providing a stable biting surface and guiding the jaw.
- Night Guard: Often made from a softer, more flexible material, or a dual-laminate material (a soft inner layer and a hard outer layer).
Design and Fit
- Bite Splint: Designed to create a very specific, therapeutic bite relationship. The dentist will take precise measurements and impressions to ensure the splint guides the jaw into the correct position.
- Night Guard: A simpler design focused on creating a protective barrier between the teeth. It’s made to fit snugly over either the top or bottom teeth.
Think of it this way: if your jaw pain is the main issue, a bite splint is the treatment. If protecting your teeth from wear is the main issue, a night guard is the solution.
Benefits of Using a Bite Splint
A bite splint offers a range of benefits, particularly for those dealing with more significant jaw problems:
- Reduces Jaw Pain and Discomfort: By repositioning the jaw joint, a bite splint can significantly alleviate chronic pain in the jaw, face, and head.
- Relaxes Jaw Muscles: It helps to break the cycle of muscle clenching, leading to long-term muscle relaxation and reduced soreness.
- Treats TMD Symptoms: It’s an effective, non-invasive treatment for a wide range of TMD symptoms, including clicking, popping, and locking of the jaw.
- Protects Teeth: While it’s a treatment for the jaw, it also provides excellent protection against the forces of grinding and clenching, preventing tooth wear and damage.
- Improves Sleep Quality: By reducing discomfort and muscle tension, it can lead to a more restful night’s sleep.
Benefits of Using a Night Guard
For many people, a night guard is all that’s needed to manage their bruxism:
- Protects Teeth from Damage: This is the primary and most important benefit. It prevents enamel erosion, chipped teeth, and cracked fillings.
- Reduces Headaches and Jaw Soreness: By absorbing the force of clenching, it can help alleviate morning headaches and jaw soreness, which are common symptoms of bruxism.
- Prevents Further Wear and Tear: It’s a proactive way to preserve the long-term health and integrity of your teeth, saving you from costly dental work down the track.
- Cost-Effective: While custom-made night guards are an investment, they are generally less expensive than bite splints and are a far more affordable solution than extensive dental restorations caused by grinding.
- Easy to Use: Once you get used to it, a custom night guard is comfortable and easy to wear.
Which Option is Right for You?
The choice between a bite splint and a night guard ultimately depends on your specific symptoms and the diagnosis from your dentist.
You might need a Night Guard if:
- Your primary symptom is teeth grinding (bruxism), and you are worried about damage to your teeth.
- You wake up with a sore jaw, headaches, or notice wear on your teeth, you might be experiencing teeth clenching or grinding during sleep.
- A dental examination reveals signs of tooth wear, including flattened chewing surfaces or chipped teeth.
- Your dentist determines that your jaw joint is healthy and your bite is well-aligned.
A dentist Chatswood, a Lindfield dentist, or a dentist in Balmain can help you determine if a night guard is the right solution for your bruxism.
You might need a Bite Splint if:
- You have been diagnosed with temporomandibular joint disorder (TMD).
- You experience chronic jaw pain, as well as locking, clicking, and popping sounds in your jaw.
- Your jaw muscles feel constantly tense and sore.
- Your dentist recommends a device to reposition your jaw and relieve muscle strain.
A specialist in TMD, a dentist in Artarmon, or a Willoughby dentist with experience in treating complex bite issues will be able to provide a comprehensive evaluation and recommend the appropriate bite splint.
It is absolutely crucial to consult a qualified dentist to get a proper diagnosis. They will examine your bite, check your jaw joints for any issues, and help you decide on the best course of action.
How They Are Made and Fitted
Both devices are custom-made by a dental laboratory based on impressions of your mouth, but the process has some differences.
- Consultation and Examination: The process begins with a thorough examination by your dentist. They will assess your jaw, teeth, and muscles. For a bite splint, this examination is more detailed.
- Impressions and Models: The dentist will take precise impressions or use a digital scanner to create a 3D model of your teeth.
- Fabrication: The impressions are sent to a dental lab where the device is created. A bite splint requires more precise measurements to ensure the jaw is guided correctly. A night guard is a more straightforward process.
- Fitting and Adjustments: Once the device is ready, you’ll return to the dentist for a fitting. The dentist will make sure it fits perfectly and feels comfortable. Bite splints often require a few follow-up appointments for minor adjustments to ensure the jaw is properly aligned.
Caring for Your Bite Splint or Night Guard
Proper care is essential to keep your device clean and hygienic, ensuring it lasts for a long time.
- Clean Daily: Rinse your device with cold water after each use. Use a soft toothbrush and mild soap or a non-abrasive denture cleaner to gently scrub it. Avoid using toothpaste as it can be too abrasive and scratch the surface.
- Store Properly: Keep your device in its protective case when you’re not wearing it. This prevents it from getting lost, damaged, or collecting dust.
- Avoid Heat: Never clean your device in hot water or leave it in direct sunlight. High heat can warp the material, ruining the fit.
- Regular Check-ups: Bring your night guard or bite splint with you to your regular dental check-ups. Your dentist can inspect it for wear and tear and give it a professional cleaning.
Cost Comparison
The cost of a custom-made dental device can vary depending on the material, the complexity of the case, and the dentist’s fees.
- Night Guard: A custom-made night guard is an investment, but it’s much cheaper than repairing chipped or worn-down teeth. The price can range from a few hundred dollars to around $1000 AUD.
- Bite Splint: Due to the more complex design and therapeutic purpose, a bite splint is generally more expensive than a night guard. The cost can be higher, reflecting the materials and the precision needed for its fabrication.
Check with your private health fund, as many policies provide coverage for dental appliances like night guards and bite splints.
Conclusion
Both a bite splint and a night guard are fantastic tools for protecting your smile and managing bruxism. However, they are not the same thing. A night guard is a protective device for grinding, while a bite splint is a therapeutic device for more serious jaw issues like TMD.
The most important step is to speak with a qualified dentist. They can properly diagnose the cause of your symptoms and recommend the best treatment plan for you. Whether you’re in Balmain, Chatswood, Lindfield, Artarmon, or Willoughby, a local dentist can help you find relief and protect your teeth for years to come.
