The Ultimate Buying Guide: Choosing a Mouthguard for Working Out
Many athletes wear mouthguards during contact sports like boxing or rugby. However, more people now wear them during heavy weightlifting or high-intensity interval training (HIIT). Clenching your jaw during a tough set can lead to tooth damage or jaw pain. A good mouthguard protects your teeth and helps you stay focused.
Key Features to Look For
When shopping for a mouthguard, look for a slim design. You need to breathe easily while you push through your workout. A bulky guard will make it hard to talk or drink water. You should also look for a secure fit. The guard should stay in place without you having to bite down hard to hold it.
Important Materials
Most mouthguards are made from medical-grade silicone or thermoplastic. These materials are soft enough to feel comfortable but strong enough to absorb impact. Look for “BPA-free” and “latex-free” labels. You put this item in your mouth daily, so you want to ensure the materials are safe and non-toxic.
Factors That Improve or Reduce Quality
Quality often comes down to how the guard fits your teeth. “Boil-and-bite” guards are popular because they mold to your unique mouth shape. If a guard does not mold well, it will feel loose and uncomfortable. High-quality guards usually feature a thinner profile in the front to improve airflow. Low-quality guards are often too thick, which can cause excess saliva and gagging.
User Experience and Use Cases
If you lift heavy weights, you likely clench your teeth during the “sticking point” of a lift. A mouthguard acts as a cushion for your jaw muscles. This helps prevent tension headaches. For HIIT athletes, a thin, lightweight guard is best. It won’t interfere with your heavy breathing. Always clean your guard with mild soap or a specialized tablet to keep it fresh.
Frequently Asked Questions
Q: Can I drink water while wearing my mouthguard?
A: Yes, most slim-profile mouthguards allow you to drink water without taking them out.
Q: How do I clean my mouthguard?
A: Rinse it with cold water after every use. Once a week, use a gentle mouthguard cleaner or mild dish soap.
Q: How long does a mouthguard usually last?
A: Most guards last between 3 to 6 months depending on how often you clench your teeth.
Q: Will a mouthguard help me lift more weight?
A: It may help you feel more stable. By relaxing your jaw, you can focus more energy on your actual lift.
Q: Can I wear a mouthguard if I have braces?
A: You should talk to your dentist first. Some guards are specifically designed for braces, but standard ones might not fit correctly.
Q: What is the “boil-and-bite” process?
A: You place the guard in hot water to soften the material. Then, you bite down on it to create a custom mold of your teeth.
Q: Does a mouthguard prevent jaw pain?
A: Yes, it acts as a shock absorber. It reduces the strain on your jaw joints during heavy exertion.
Q: Should I choose a thick or thin guard?
A: For lifting, thin is usually better. It is more comfortable and lets you breathe much easier.
Q: Can I talk while wearing it?
A: A well-fitted, slim mouthguard should allow you to speak clearly enough to communicate with your gym partner.
Q: What should I do if my mouthguard feels loose?
A: If it is a boil-and-bite style, you can try molding it again. If it remains loose, it is time to replace it.
