Mouth guards are indispensable for protecting your teeth, gums, and jaw from damage caused by high-impact sports, clenching, or other physical activities. They are typically made from a range of materials, including basic plastics like PVC, thermoplastics like EVA, and premium polymers that are BPA-free. While disposable mouth guards are often made from cheaper plastics, custom mouth guards are designed to be more durable and sustainable. The material used for custom mouth guards is chosen based on its strength, ductility, and safety, with EVA being a popular choice for its lightweight, durable, and shock-absorbing properties. Hard night guards, made from acrylic materials, are often recommended for severe cases of grinding and clenching, while soft night guards, made from ethylene-vinyl acetate, are more comfortable and flexible.

Mouth guards are made from hard plastic to protect teeth, gums, and jaws during high-impact sports or physical activities
Mouth guards are an essential piece of protective equipment for individuals engaging in high-impact sports or physical activities. They shield the teeth, gums, and jaws from potential damage caused by forceful contact or clenching. To fulfil this protective role, mouth guards are often made from hard plastic, which offers several advantages.
The use of hard plastic in mouth guard construction provides superior impact resistance compared to softer materials. This rigidity is crucial for absorbing and distributing the forces exerted on the teeth and jaws during high-impact activities, such as boxing, hockey, or rugby. The hardness of the plastic helps dissipate the impact energy, reducing the risk of dental injuries.
Additionally, hard plastic mouth guards are more durable and long-lasting. The material's toughness and resistance to deformation ensure that the mouth guard retains its shape and protective capabilities over extended periods. This durability is especially important for individuals who consistently engage in high-impact sports, as it provides a reliable level of protection throughout the lifespan of the mouth guard.
While hard plastic mouth guards excel in impact protection and durability, they may be less comfortable than their softer counterparts. Soft mouth guards, often made from ethylene-vinyl acetate (EVA), are more flexible and conform better to the unique contours of an individual's teeth. This flexibility can make soft mouth guards more comfortable for light grinders or during sleep, as they may feel less bulky or intrusive in the mouth.
However, for individuals who clench or grind their teeth severely, hard mouth guards made from acrylic or copolyester resins are usually recommended. These materials are more rigid and better able to withstand the forces exerted by powerful clenching or grinding. Hard mouth guards can provide the necessary support to alleviate pressure on the jaw and prevent further dental damage caused by heavy grinding.
In conclusion, mouth guards made from hard plastic are specifically designed to offer maximum protection during high-impact sports or physical activities. While comfort and flexibility may be compromised, the hardness of the plastic ensures superior impact absorption and durability. For individuals requiring maximum protection for their teeth, gums, and jaws, hard plastic mouth guards are the optimal choice.

They are also used to treat chronic teeth grinding and clenching, which can cause significant damage to teeth
Mouth guards are used to treat chronic teeth grinding and clenching, also known as bruxism. This condition can cause significant damage to teeth, including chipped teeth, knocked-out teeth, and damage to the tooth pulp. Mouth guards provide a barrier between the teeth, giving teeth something to grind on other than other teeth. They can also help to reduce the risk of soft-tissue injuries to the gums, lips, and inner cheeks.
There are different types of mouth guards available, and the choice of material can affect the comfort and durability of the mouth guard. Basic plastics like PVC are inexpensive and easy to find, but they may not provide adequate protection for high-impact sports or prolonged use. Thermoplastics like EVA are affordable and semi-customizable, but they are less durable and comfortable than professionally crafted options. Premium EVA or BPA-free polymers offer a tailored fit, maximum comfort, and superior protection, but they are more costly. Soft, flexible night guards are often made from ethylene-vinyl acetate (EVA), which is considered safe.
Custom-fitted mouth guards are recommended for treating bruxism, as they provide the best comfort and protection. They can be made from hard, durable, heat-cured plastic, or softer acrylic-based materials for increased patient comfort. The material used should be non-toxic and safe for extended wear. Some mouth guards are made from copolyesters, which are thermoplastic resins that retain their strength and clarity and can be customized through thermoforming. Medical-grade silicone is used in softer mouth guards, but it may not provide the same level of protection as EVA or acrylic for high-impact sports.
While mouth guards can be effective in preventing tooth damage caused by bruxism, they do not solve the underlying dental problems. In some cases, over-the-counter mouth guards can even make underlying conditions worse. Therefore, it is important to consult a dentist or healthcare provider to determine the best treatment approach for bruxism, which may include a combination of a mouth guard and other treatments.

Hard night guards are made from acrylic resins, copolyesters, or ethylene-vinyl acetate copolymers
Mouth guards are made from a variety of materials, including plastics, resins, and silicone. Hard night guards, in particular, are typically made from acrylic resins, copolyesters, or ethylene-vinyl acetate (EVA) copolymers. These materials are chosen for their durability and strength, making them ideal for protecting teeth against grinding and clenching during sleep.
Acrylic resins are rigid materials commonly used in night guards to protect against teeth grinding and clenching. They are highly durable but lack the flexibility required for sports mouth guards. Acrylic resins have been associated with methyl methacrylate (MMA), which has been linked to respiratory and neurological issues in humans upon direct exposure. However, manufacturers of hard night guards that contain MMA claim that the "cured" state of the material prevents it from leaching into the body. As a result, individuals concerned about MMA exposure can opt for MMA-free night guard alternatives.
Copolyesters are a type of thermoplastic resin used in hard night guards. They retain their strength and clarity and can be thermoformed to create custom-fitted night guards. Copolyesters are considered safe, with no reported toxicity in MSDS sheets. However, it is always advisable to follow the manufacturer's guidelines and best practices when handling and using these products.
Ethylene-vinyl acetate (EVA) copolymers are another common material used in hard night guards. EVA is known for its excellent shock absorption and lightweight properties, making it a popular choice for sports mouth guards as well. EVA has been thoroughly studied and is not considered carcinogenic by several health organizations. It is also used in soft night guards, providing a comfortable and safe option for users.
In conclusion, hard night guards made from acrylic resins, copolyesters, or ethylene-vinyl acetate copolymers offer durability and protection for teeth grinding and clenching. While concerns about the presence of harmful chemicals like MMA and BPA exist, reputable dental labs prioritize human safety by using the highest quality materials. The choice of material depends on individual needs, and consulting with dental professionals is essential for personalized guidance on night guard selection.
