Why a Mouth Guard for Biting Tongue is Necessary

From my own experience, biting my tongue during sleep or intense activities was not only painful but also disrupted my daily routine. A mouth guard became essential because it provides a protective barrier that prevents my teeth from accidentally cutting or bruising my tongue. Without it, I would often wake up with painful sores that took days to heal.

Additionally, I noticed that whenever I was stressed or grinding my teeth, the chances of biting my tongue increased significantly. Using a mouth guard helped me manage this problem by cushioning my bite and reducing the pressure on my tongue. It made a noticeable difference in my comfort and overall oral health.

In short, a mouth guard is necessary for anyone like me who struggles with tongue biting. It’s a simple yet effective solution that protects the tongue, reduces pain, and improves quality of life.

My Buying Guide on ‘Mouth Guard For Biting Tongue’

When I first started looking for a mouth guard to prevent biting my tongue, I realized there’s more to consider than just picking the cheapest or most popular option. Here’s what I learned from my experience that might help you find the right mouth guard for your needs.

Understanding Why You Need a Mouth Guard

I found it crucial to identify why I was biting my tongue in the first place. Whether it’s due to teeth grinding (bruxism), sleep apnea, or just an accidental habit, knowing the cause helped me choose a guard designed for that specific issue. Some guards are softer for mild protection, while others are sturdier for heavy grinders.

Types of Mouth Guards Available

There are mainly three types:

  • Stock Mouth Guards: These are pre-formed and ready to wear but often feel bulky and don’t fit well. I avoided these because they didn’t stay in place for me.
  • Boil-and-Bite Mouth Guards: These let you soften the guard in hot water and mold it to your teeth. I found this option strikes a good balance between comfort and affordability.
  • Custom-Fitted Mouth Guards: Made by a dentist, these offer the best fit and protection but come at a higher price. If tongue biting severely affects your daily life, investing in one might be worth it.

Material and Comfort

Since I would be wearing the mouth guard for long periods (sometimes overnight), comfort was a top priority. Look for guards made from medical-grade silicone or EVA plastic as they tend to be softer and hypoallergenic. A bulky guard made me feel uncomfortable and tempted me to take it out during sleep.

Size and Fit

A good fit is essential to avoid irritation or the guard falling out. I recommend choosing a guard that you can mold yourself or getting a custom fit if possible. Make sure it covers your teeth and gums adequately without restricting your breathing or speech.

Ease of Cleaning

Since the mouth guard stays in your mouth, hygiene is critical. I chose a guard that’s easy to clean with just water and mild soap. Some guards come with a storage case that helps keep them sanitary between uses.

Durability and Replacement

Depending on how often you use the guard, durability matters. I noticed that some cheaper guards wear out quickly and lose their shape, so I opted for one with good reviews on longevity. Also, check the manufacturer’s recommendations on how often you should replace the guard.

Additional Features

Some mouth guards have extra benefits like anti-snoring properties or help with jaw alignment. If you have related issues, it’s worth exploring guards that address multiple concerns.

Price Considerations

I balanced cost with quality. While it might be tempting to buy the cheapest option, a poorly fitting or uncomfortable guard won’t help in the long run. Sometimes spending a bit more upfront saves money and discomfort later.

Final Thoughts

Buying a mouth guard for biting your tongue is a personal choice that depends on your specific needs and comfort. From my experience, starting with a boil-and-bite guard was a good middle ground, and if needed, upgrading to a custom-fitted one made a big difference. Take your time to read reviews, consider your lifestyle, and don’t hesitate to consult a dental professional if you’re unsure.

I hope my buying guide helps you find a mouth guard that keeps your tongue safe and gives you peace of mind!
