Why a Mouth Guard for Biting Cheeks Is Necessary
I never realized how much damage I was doing to the inside of my mouth until I started biting my cheeks regularly. It’s not just a minor annoyance—those constant bites can lead to painful sores, swelling, and even infections. Using a mouth guard has been a game-changer for me because it creates a protective barrier between my teeth and my cheeks, preventing further injury while I sleep or go about my day.
For me, the mouth guard also helps break the habit. Without it, I’d unconsciously bite down on my cheeks, especially when I’m stressed or anxious. Wearing the guard reminds me to be more mindful and gives my cheeks time to heal. Overall, having this simple device has improved my comfort and confidence, making it an essential part of managing my cheek-biting problem.
My Buying Guides on Mouth Guard For Biting Cheeks
When I first started dealing with the frustrating habit of biting my cheeks, I knew I needed a solution that would protect my mouth and help me break the cycle. That’s when I discovered mouth guards designed specifically for biting cheeks. If you’re in the same boat, here’s what I learned through my own experience to help you choose the right one.
Understanding Why You Need a Mouth Guard
Before buying a mouth guard, I realized it’s important to understand why cheek biting happens. It can be due to stress, misaligned teeth, or even just a nervous habit. A mouth guard acts as a protective barrier, preventing your teeth from damaging the soft tissues inside your mouth.
Types of Mouth Guards
There are several types of mouth guards available, and knowing which one suits your needs is key:
- Stock Mouth Guards: These are pre-formed and ready to use. I found them easy to buy but they didn’t fit perfectly, which made them less comfortable.
- Boil-and-Bite Mouth Guards: These allow you to soften the guard in hot water and then mold it to your teeth. This was my favorite type because it offered a customized fit without the higher cost of a professional guard.
- Custom-Fitted Mouth Guards: Made by a dentist, these provide the best fit and comfort. While pricier, I found them very effective if you have severe cheek biting or other dental issues.
Material and Comfort
Comfort was a big deal for me since I needed to wear the guard regularly. Look for mouth guards made from soft, flexible materials like silicone or EVA (ethylene-vinyl acetate). These materials reduce irritation and make it easier to talk and breathe while wearing the guard.
Size and Fit
A proper fit is essential. I measured my mouth and teeth before purchasing, and if possible, chose adjustable or moldable guards. Poorly fitting guards can worsen the problem by causing additional irritation or discomfort.
Durability and Maintenance
Since I planned to wear my mouth guard nightly, I wanted one that was durable and easy to clean. Look for guards that are resistant to wear and can be cleaned with simple soap and water. Some even come with a storage case to keep them hygienic.
Additional Features to Consider
Some mouth guards come with extra features like:
- Anti-bacterial coatings to reduce germs.
- Breathability for easier airflow.
- Thin profiles for less bulk in the mouth.
I found these features helpful for long-term comfort and health.
Price vs. Quality
While it might be tempting to go for the cheapest option, I learned that investing a little more in quality pays off. A well-made mouth guard lasts longer and offers better protection, saving you from further discomfort or dental problems.
When to Consult a Dentist
If your cheek biting is severe, persistent, or causing sores, I strongly recommend seeing a dentist. Sometimes, the issue may be linked to teeth alignment or other oral health concerns that need professional attention. Your dentist can also provide a custom mouth guard tailored to your needs.
Final Thoughts
Choosing the right mouth guard for biting cheeks made a huge difference in my comfort and healing process. By considering fit, material, type, and your specific needs, you can find a guard that protects your cheeks and helps you stop this habit. Remember, patience is key—breaking the cycle takes time, but with the right guard, it’s definitely doable!
