Mouth Guards: Protecting Your Smile in Multiple Ways

Mouth guards, also known as mouth protectors, are more than just a piece of plastic worn by athletes. They offer a variety of dental and health benefits for people of all ages. This article will delve into the different types of mouth guards, their uses, and the advantages of wearing one.

Understanding Mouth Guards

A mouth guard is a resilient appliance worn over the teeth, typically the upper ones. It safeguards your teeth, lips, tongue, cheeks, and jaw from injuries. Mouth guards come in various designs and materials, each suited for specific purposes.

Types of Mouth Guards:

There are three main categories of mouth guards:

  • Stock Mouth Guards: These are readily available at sporting goods stores and pharmacies. They come in pre-formed sizes that you can fit yourself by boiling and biting down on the material to mold it partially to your teeth. While affordable and convenient, they may not offer the most comfortable or secure fit.
  • Boil-and-Bite Mouth Guards: These are an improved version of stock mouth guards. They come in a more generic shape and require boiling and biting to conform better to your individual mouth shape. This offers a slightly more customized fit than generic guards.
  • Custom-Made Mouth Guards: Dentists create these guards using impressions of your teeth. This results in the most comfortable, secure, and effective mouth guard. While more expensive than store-bought options, they offer superior protection and may be more tolerable for prolonged wear.

Uses for Mouth Guards:

Mouth guards have various applications, including:

  • Sports Protection: In sports with a high risk of contact or falls, such as football, hockey, basketball, and martial arts, mouth guards are essential for preventing chipped, fractured, or knocked-out teeth.
  • Teeth Grinding (Bruxism): If you grind or clench your teeth unconsciously during sleep (bruxism), a mouth guard can cushion your teeth and minimize damage. Additionally, it can lessen bruxism-related headaches and jaw pain.
  • TMJ Disorders: Temporomandibular joint (TMJ) disorders can cause jaw pain, clicking, and difficulty chewing. Mouth guards can help stabilize the jaw joint and reduce discomfort.
  • Sleep Apnea: In some cases, specially designed mouth guards can help maintain an open airway during sleep, improving symptoms of sleep apnea.

Benefits of Wearing a Mouth Guard:

The advantages of wearing a mouth guard go beyond just protecting your teeth. Here are some key benefits:

  • Reduced Dental Injuries: Mouth guards significantly lower the risk of injuries to your teeth, lips, tongue, cheeks, and jaw during sports or accidents.
  • Preserves Dental Work: If you have dental restorations like crowns, bridges, or veneers, a mouth guard can safeguard them from damage.
  • Improved Sleep Quality: For those who grind teeth at night, mouth guards can promote better sleep by preventing teeth grinding and clenching, and the associated discomfort.
  • Reduced Jaw Pain: Mouth protectors can help alleviate pain caused by TMJ disorders by stabilizing the jaw joint.
  • Enhanced Athletic Performance: Some athletes report feeling more confident and focused while wearing a mouth guard, potentially improving performance.

When to Wear a Mouth Guard

The need to wear a mouth guard depends on the reason you're using it. Here's a breakdown of the different scenarios:

For Sports Protection:

  • During all practices and games:If you participate in contact sports with a high risk of falls or collisions, such as football, hockey, basketball, martial arts, or even gymnastics, it's crucial to wear your mouth guard consistently throughout practices and games. Even seemingly minor falls or contacts can damage teeth.

For Teeth Grinding

  • Every night while sleeping:If you grind or clench your teeth unconsciously at night, a mouth guard is most effective when worn nightly. This protects your teeth from the wear and tear caused by grinding and clenching, and can also help alleviate jaw pain and headaches associated with bruxism.

For TMJ Disorders:

  • As directed by your dentist:For TMJ disorders, your dentist will determine how often you should wear a mouth guard. It might be recommended for daytime use, nighttime use, or both, depending on the severity of your symptoms.

Choosing the Right Mouth Guard:

When selecting a mouth guard, consider the following factors:

  • Your Needs: If you need a mouth guard for sports, a boil-and-bite or custom-made option might be ideal. For teeth grinding, a custom-made guard is usually recommended.
  • Comfort and Fit: A comfortable and well-fitting mouth guard is essential for prolonged wear. Custom-made guards offer the best fit and comfort.
  • Budget: Store-bought mouth guards are the most affordable, while custom-made guards are more expensive.

Consulting your dentist is crucial to determine the most suitable type of mouth guard for your specific needs. They can also advise on proper care and cleaning of your mouth guard.

How to Maintain a Mouth Guard

Keeping your mouth guard clean and functional is crucial to get the most out of it. Here's a breakdown of the key maintenance practices:

Cleaning Routine:

  • After Each Use: Rinse your mouth guard thoroughly with cool water immediately after taking it out. This removes saliva and loose debris that can harbor bacteria.
  • Gentle Brushing (Optional): You can give your mouth guard a gentle brushing with a soft-bristled toothbrush and non-abrasive toothpaste. This helps remove any remaining debris, especially if you grind your teeth at night.
  • Deep Clean (Monthly): For a deeper clean, at least once a month, soak your mouth guard in a denture cleaner solution or a mixture of equal parts white vinegar and water. Let it soak for 15-30 minutes, then rinse it thoroughly with cool water. Avoid harsh chemicals, bleach, or hot water, as they can damage the guard.

Drying and Storage:

  • Air Drying is Key: After rinsing, allow your mouth guard to air dry completely. Moisture can promote bacterial growth. Leave it out in its vented container or on a clean cloth.
  • Store Wisely: Keep your mouth guard in a vented container when not in use. This allows for proper air circulation and drying. Avoid storing it in direct sunlight or extreme heat.
  • Travel Ready: When transporting your mouth guard, keep it in its container to protect it from dirt, debris, and getting crushed.

Common Myths about Mouth Guards

Despite their well-established benefits, mouth guards are shrouded in a few common myths. Let's debunk some of these misconceptions to ensure you make informed decisions about protecting your smile:

Myth 1: Mouth guards are only for athletes.

Fact: While mouth protectors are widely used in sports, their benefits extend far beyond the athletic field. Anyone participating in activities with a risk of falls or impacts, like skateboarding, cycling, or even horseback riding, can benefit from mouth guard protection. Additionally, dentists often recommend mouth protectors for people who grind their teeth at night (bruxism) or suffer from temporomandibular joint (TMJ) disorders.

Myth 2: Mouth guards make breathing and speaking difficult.

Fact: Well-fitting mouth protectors, particularly custom-made ones, shouldn't significantly hinder breathing or speaking. If you experience discomfort, it might be due to an ill-fitting mouth guard. Consult your dentist to ensure you have the right type and proper fit.

Myth 3: Children don't need mouth guards.

Fact: Children's teeth are still developing and more susceptible to damage. Even during seemingly harmless activities like playing on the playground, falls or collisions can lead to dental injuries. Mouth protectors offer valuable protection for children participating in sports or high-impact activities.


Mouth guards are a valuable tool for protecting your oral health and overall well-being. Whether you're an athlete, teeth grinder, or someone suffering from TMJ issues, a mouth guard can offer significant benefits. By understanding the different types and their uses, you can choose the right mouth guard to keep your smile healthy and protected.
