Is It Better to Have a Mouthguard for Teeth Grinding on Top or Bottom Teeth?

If you’re struggling with teeth grinding (bruxism), you’re likely considering a mouthguard to protect your teeth and alleviate discomfort. But one common question arises: Is it better to wear a night guard on the top or bottom teeth?

The answer isn’t one-size-fits-all, as it depends on your specific needs, comfort, and the severity of your condition. In this blog, we’ll explore the pros and cons of each option, helping you make an informed decision about the best mouthguard for teeth grinding.

Understanding Teeth Grinding and the Role of a Mouthguard

Teeth grinding, or bruxism, is a condition where you unconsciously clench or grind your teeth, often during sleep. Over time, this can lead to worn-down enamel, jaw pain, headaches, and even cracked teeth. A mouthguard for teeth grinding acts as a protective barrier, absorbing the pressure and preventing damage to your teeth.

But where should you place the mouthguard—on the top or bottom teeth? Let’s break it down.

Top Teeth vs. Bottom Teeth: Which is Better for a Mouthguard?

1. Mouthguard on Top Teeth

Placing a mouthguard on the top teeth is the most common recommendation by dentists. Here’s why:

Stability and Comfort: The upper jaw is typically more stable, making it easier to keep the mouthguard in place throughout the night.
Protection for Lower Teeth: When you grind, the lower teeth move against the upper teeth. A top mouthguard cushions this impact, protecting both arches.
Ease of Use: Many people find it more comfortable to wear a mouthguard on their top teeth, as it feels less intrusive.

However, some individuals may find a top mouthguard bulky or uncomfortable, especially if they have a strong gag reflex.

2. Mouthguard on Bottom Teeth

While less common, a bottom teeth mouthguard can be a suitable option for certain individuals. Here are the benefits:

Less Intrusive: A lower mouthguard can feel less bulky, making it a better choice for those who struggle with the sensation of a top guard.
Suitable for Specific Cases: If you have dental work on your lower teeth, such as crowns or bridges, a bottom mouthguard may provide better protection.
Custom Fit: Some people find that a lower mouthguard fits more securely, especially if they have a smaller jaw or unique dental structure.

On the downside, a bottom mouthguard may not provide as much protection for the upper teeth, and it can sometimes shift during sleep.

Factors to Consider When Choosing a Mouthguard for Teeth Grinding

1. Comfort and Fit

The most important factor is how comfortable the mouthguard feels in your mouth. Whether you choose a top or bottom mouthguard, it should fit snugly without causing discomfort or interfering with your sleep.

2. Severity of Bruxism

If you have severe bruxism, a top mouthguard may offer better protection. However, mild cases may benefit from either option.

3. Dental Work and Jaw Structure

Consider any existing dental work, such as crowns, bridges, or implants, as well as your jaw structure. Your dentist can help you determine which option is best for your unique situation.

4. Personal Preference

Ultimately, your preference plays a significant role. Some people simply find one option more comfortable than the other.

Types of Mouthguards for Teeth Grinding

Not all mouthguards are created equal. Here are the main types to consider:

1. Custom-Fitted Mouthguards

Made by your dentist, these offer the best fit and protection. They are tailored to your teeth, ensuring maximum comfort and effectiveness.

2. Boil-and-Bite Mouthguards

These are available over-the-counter and can be moulded at home. While more affordable, they may not provide the same level of protection as custom-fitted guards.

3. Stock Mouthguards

Pre-made and ready to wear, these are the least expensive option but often lack a proper fit and can be uncomfortable.

Tips for Maintaining Your Mouthguard

To ensure your mouthguard lasts and remains effective, follow these maintenance tips:

Clean Daily: Rinse your mouthguard with cool water after each use and brush it with a soft toothbrush and mild soap.
Store Properly: Keep it in a ventilated case to prevent bacteria growth.
Avoid Heat: Don’t expose your mouthguard to hot water or direct sunlight, as this can warp the material.
Replace When Needed: Over time, mouthguards can wear out. Replace yours as soon as you notice signs of damage or wear.

What Do the Experts Say?

Here are some key insights:

Highlights that upper mouthguards are more common due to their stability and ease of use. They also emphasise the importance of a custom-fit guard for maximum protection.
Discusses how lower mouthguards can be beneficial for individuals with specific dental work or those who find upper guards uncomfortable.
Focuses on the importance of comfort and fit, recommending a consultation with a dentist to determine the best option.

Combining these insights, it’s clear that the choice between a top or bottom mouthguard depends on individual factors like comfort, dental structure, and the severity of bruxism.

Final Thoughts

Choosing the right mouthguard for teeth grinding whether for the top or bottom teeth is a personal decision that depends on your unique needs. While upper mouthguards are more commonly recommended, lower mouthguards can be a viable alternative for some individuals.

If you’re unsure which option is best for you, consult your dentist. They can assess your condition, recommend the most suitable type of mouthguard, and ensure it fits perfectly. Remember, the goal is to protect your teeth, alleviate discomfort, and improve your quality of sleep.

By following these guidelines and understanding the pros and cons of each option, you can make an informed decision and take the first step toward protecting your smile. Whether you choose a top or bottom mouthguard, the most important thing is to address your teeth grinding before it leads to more serious dental issues.
