Mouth Guards for Sports and Sleep: A Complete Guide in NZ

Has it ever happened that you wake up with a sore jaw and your teeth hurt like they were in a fight throughout the night? Or have you ever faced a scenario in which you get hit in the face with a basketball because you were not wearing any protection and your jaw got hurt, or your teeth got chipped? Whether it’s a rough night’s sleep or a rough tackle on the field, your teeth take the hit. To do that, you need to shield your teeth using a protective device.. We call that device a mouth guard. Mouth guards are not just for pro athletes or people with severe grinding issues; they are for anyone who values their smile and comfort.

In New Zealand, awareness of both sports and night mouth guards is growing. More Kiwis, from school-aged rugby players to stressed-out office workers, are turning to custom mouthguards to protect their teeth. So, what kind of mouth guards in New Zealand do you need? And how do you know which one’s worth it? Let’s break it down.

What Are Mouth Guards?

Simply put, a mouth guard is a device you wear over your teeth to keep them safe from injury or damage. You pop it in before bed if you're grinding, or before you hit the pitch, so that you can protect your teeth or jaw while playing any form of sport. Its job is to act like a cushion between the upper and lower teeth, absorbing shocks and preventing serious dental damage.

Types of Mouth Guards

Not all mouth guards are the same. In New Zealand, you will find three main types:

• Stock Mouth Guards

A stock mouthguard is commonly available at sports stores and is designed to be worn immediately without any customization. While it is an affordable option and easily accessible, it typically comes in standard sizes that may not fit everyone comfortably. Because it is not custom-molded, a stock mouthguard can feel bulky or loose in the mouth, making it harder to speak or breathe naturally. Still, for someone looking for quick, temporary protection, especially young athletes or beginners, it offers a simple and low-cost way to safeguard their teeth during physical activities. It's not perfect, but it’s a start toward prioritizing dental safety.

• Boil-and-Bite

A boil-and-bite mouthguard offers a personalized way to protect your teeth, whether you are gearing up for a game or trying to sleep peacefully through the night. Crafted from thermoplastic material, it becomes pliable in hot water, letting you bite into it to shape it around your teeth. This provides a secure, comfortable fit without requiring a visit to the dentist.

It's an accessible solution for anyone looking for both protection and convenience, especially for kids, athletes, or people dealing with nighttime teeth grinding. While it's not an alternative to a custom-fit mouthguard, it strikes a thoughtful balance between affordability and functionality.

• Custom Mouthguards

A custom mouth guards isn’t just a piece of plastic; it’s personal protection crafted just for you. Whether you’re hitting the rugby field or grinding your teeth in your sleep, it’s molded to fit the unique shape of your mouth, offering comfort, security, and peace of mind. Unlike bulky over-the-counter versions, a custom-fit guard feels so comfortable, allowing you to speak, breathe, and play without distraction. It’s a small but powerful investment in your long-term oral health, designed to shield your teeth, gums, and jaw with precision.

Why Your Smile Needs a Mouth Guard

Your smile needs a mouthguard in two situations. If you are grinding your teeth at night (a condition known as bruxism), you are slowly wearing away your enamel and possibly giving yourself chronic jaw pain. And if you are playing sports, especially contact sports, you are always one awkward fall away from a chipped tooth or worse. That is when you will need a mouthguard.

What Do Mouth Guards Offer?

• Injury prevention: A mouthguard helps you to stay safe from tooth fractures and jaw injuries.
• Bruxism protection: if you grind your teeth while sleeping, a mouthguard acts as a cushion, minimising wear and muscle tension.
• Better sleep: It also helps you get a better and comfortable sleep, especially if you have clenching issues or light sleep apnea.
• Improved sports performance: Wearing a mouthguard during high-impact sports increases your confidence as your teeth and jaw are protected, and you are more focused on your game.

And yes, they are not just for adults. There is a growing demand for kids' mouth guards, too, especially with school sports in full swing.

Sports Mouth Guards for Protection &Performance

If you're not wearing a mouth guard in New Zealand and you’re into sports, you’re asking for trouble. Rugby, hockey, boxing, basketball, even skateboarding or netball, all pose risks. And it’s not just the pros who need protection. Kids and teens are at even higher risk due to ongoing dental development.

Mouth guards for sports help prevent:

• Broken or knocked-out teeth
• Concussions
• Jaw dislocations
• Soft tissue injuries

There are options designed for kids' mouth guards with smaller sizes and softer materials, and more rigid versions of mouth guards for adults with better grip, longer wear, and improved shock absorption.

Just don’t make the mistake of using a sports guard as a night guard. They’re not interchangeable.

What is a Sleep Mouthguard?

Grinding, clenching, jaw pain, sore temples, sound familiar? A sleep mouth guard (often called a night guard) is a solution you are looking for. It is designed to prevent these exact problems. Unlike sports guards, they are thinner, designed for comfort during long wear, and are often softer (though some need a harder shell for heavy grinders).

Sleep mouthguards help prevent:

• Worn-down or cracked teeth
• Jaw pain and tightness
• Morning headaches
• Sore facial muscles
• Disrupted sleep
• Long-term enamel loss

How to Choose the Best Mouth Guard for Sleeping and Sport

To choose the best mouthguard for sleep and sports, you have to consider certain factors. This decision really comes down to how you’ll use it and what feels right in your mouth. Let’s first compare the types of mouth guards for a better understanding:

So ask yourself:

• Do you grind your teeth nightly?
• Do you or your kid play rugby every weekend?.
• Do you prefer budget-friendly option or the quality and comfort

Other Factors to Consider

Some other factors that are to be considered before choosing a sleep mouthguard or a sports mouthguard are given below:

Purpose

Start with the “why.”

• For Sports: You’ll need a mouth guard that can absorb heavy impacts, especially for contact sports like rugby, boxing, or hockey.
• For Sleep: Look for night guards designed specifically for bruxism (teeth grinding) or clenching. These offer jaw support and protect your enamel while you rest.

Fit & Comfort

If your mouthguard is not comfortable, you won’t wear it.

• Stock guards are the least comfortable and may feel bulky.
• Boil-and-bite guards offer a better fit and mold to your teeth at home.
• Custom mouth guards are made from impressions and provide the best, most personalized fit, especially for long-term use.

Ease of Maintenance

Choose a mouth guard that’s easy to clean and store.

• Look for antibacterial materials or guards that come with a storage case to keep things hygienic.
• You’ll be using it often, so make sure it’s simple to rinse, brush, or soak.

Budget & Value

Your mouth and your money both matter.

• Stock guards are budget-friendly but may compromise on fit.
• Boil-and-bite offers a nice balance of cost and customization but cannot be used for longer period of time.
• Custom guards are an investment, but often worth it for serious athletes or long-term sleepers.

Custom Mouthguards in New Zealand: Are They Really Worth the Hype?

After reading till now, you might be wondering, are custom mouthguards in New Zealand really worth the hype? In one word: absolutely. Stock guards can feel like chewing on rubber tires, and while boil-and-bite options are a step up, they are still not worth considering, especially for professional athletes and heavy grinders. Custom mouthguards, on the other hand, fit perfectly, feel comfortable, and offer the best protection.

• Dry thoroughly – Pat with a clean towel and air dry fully before storing.
• Store properly – Keep in a clean, ventilated case to avoid dirt, damage, and germs.
• Check regularly – Look for cracks, tears, or loose fit; replace yearly or if damaged.
