Mouth guards are an absolute necessity to protect your teeth , gums, and jaw from damage caused by high-impact sports, clenching, or other physical activities. But have you ever wondered, what are mouth guards made of? Are these materials safe, especially when you wear the device for extended periods?

This blog discusses various materials that are incorporated into mouth guards, their safety, and the importance of making the right selection. We’ll also explore ALIGNERCO’s custom sports mouth guards, offering a perfect combination of safety, quality, and affordability.

The Basics: What Are Mouth Guards Made Out Of?

Mouth guards are made from a range of materials to meet different requirements. These materials are chosen according to their strength, ductility, and safety. Here’s a closer look at the most common ones:

EVA (Ethylene Vinyl Acetate)

EVA is lightweight, durable, and shock-absorbing, making it the gold standard for most high-quality sports and custom mouth guards. Its flexibility allows it to mold to the unique shape of your teeth.

Polyvinyl Chloride (PVC)

PVC is often used in low-cost, stock mouth guards. While inexpensive, it lacks the durability and comfort of EVA, making it less suitable for high-intensity sports or prolonged use.

Acrylic Resins

Acrylic resins are rigid materials used primarily in night guards designed to protect against teeth grinding or clenching. They are highly durable, but their flexibility is insufficient to cover the demands of sport.

Medical-Grade Silicone

Medical-grade silicone is used in softer mouth guards. Though comfortable, it doesn’t provide the same level of protection as EVA or acrylic in high-impact sports.

BPA-Free Polymers

Modern mouth guards, such as those from ALIGNERCO, prioritize safety by using BPA-free materials. These polymers are non-toxic and safe for extended wear.

Why the Material Matters

The material of a mouth guard plays an important role in performance and safety. Different materials offer unique benefits:

  • EVA offers superior shock absorption for high-impact sports.
  • Silicone is ideal for individuals with sensitive teeth.
  • BPA-free materials provide peace of mind for those concerned about potential toxins.

The simple answer is yes but it depends upon the following factors:

Material Safety

Reputable manufacturers guarantee that their mouth guards are not contaminated with toxic substances such as BPA and latex. High-performance thermoplastics and medical-grade silicones are subjected to rigorous safety testing. For example, ALIGNERCO's custom sports mouth guards are made of non-toxic, BPA-free materials to better protect the user's health.

Proper Fit

An inappropriate-fitting mouth guard may lead to discomfort, irritation, or cause breathing problems. Tailored mouth guards designed for the individual’s dental contours offer close fit and reduce these risks.

Maintenance and Hygiene

A well-maintained mouth guard is crucial for safety. Poor hygiene can result in bacterial accumulation which can lead to infection. Follow these maintenance tips to keep your mouth guards in optimal condition:

  • Daily Cleaning: Rinse your mouth guard with tap water after each use.
  • Weekly Cleaning: Use a mild cleanser or specialized mouth guard cleaning solution.
  • Proper Storage: Store it in a ventilated box to avoid bacterial and mold growth.

FAQs

1. Can I wear a mouth guard over braces?

Yes, you can wear a mouth guard over braces, and it is very much recommended if you play sports or if you grind your teeth. Specially designed orthodontic mouth guards are made to accommodate the brackets and wires of braces without causing discomfort.

2. How do I know if my mouth guard fits properly?

An adequately fitted mouth guard should feel snug and fixed but not painful or uncomfortable. It should remain fixed at mouth opening or speech time and cover all the teeth without protruding over the gum line. If the mouth guard is too loose, too bulky or it's irritating, the mouth guard might not be the right choice.

3. Should I wear the same mouth guard for sports and teeth grinding?

It is not advisable to use the same mouth guard for both purposes. Sports bite guards are intended for impact protection in sports, and night guards are intended for protection against teeth grinding (bruxism). Everyone has a different function and has been made with a different material to be effective. For example, the sports mouth guard may lack the strength to resist grinding forces. ALIGNERCO provides customized designs for every application, providing the best possible protection that is individual to your requirements.

4. What should I do if my mouth guard gets damaged?

If your mouth guard is cracked, deformed, or otherwise compromised, it is important to substitute it right away. A defective mouth guard may offer insufficient protection and even have a negative impact. Have a routine Mouth guard check for signs of wear and tear, particularly if you wear it daily.

5. Is it safe to share a mouth guard with someone else?

No, sharing a mouth guard is unsafe and is therefore strongly discouraged. Mouth guards are personal dental devices designed to fit the specific shape of an individual’s teeth and mouth. Sharing has the potential to facilitate improper fit, less protection, and a higher risk of transmission of bacteria, viruses, and infections.
