Mouth guards, also known as night guards, are dental appliances that fit over teeth to protect them from the damaging effects of bruxism, a condition characterised by teeth grinding and jaw clenching during sleep. They are also recommended for those who play contact sports. Mouth guards can be store-bought or custom-made, with the latter being more comfortable and durable. Custom-made mouth guards are created by dentists to fit a patient's exact dental anatomy. They are made from dental impressions, which are sent to a dental lab where a technician fabricates the mouth guard. Common materials used in the manufacturing of night guards include acrylic, polyvinyl chloride (PVC), thermoplastic elastomers (TPE), and ethylene-vinyl acetate (EVA) copolymers. While mouth guards are designed to protect teeth, there are concerns about the potential release of microplastics and the presence of harmful chemicals such as BPA, phthalates, and MMA.

What You'll Learn
Custom-made vs. store-bought
Mouth guards are dental appliances that fit over the teeth. They are recommended for a variety of reasons, including teeth grinding, clenching or gnashing (bruxism), playing contact sports, and activities with a high risk of falling. Mouth guards can be either store-bought or custom-made.
Custom-made mouth guards are created by a dentist to fit a patient's exact dental anatomy. The process involves taking an impression of the patient's teeth using dental putty or a digital handheld wand, which is then sent to a dental lab where the mouth guard is fabricated. Custom-made mouth guards offer a more comfortable and precise fit, providing effective protection against bruxism and sports-related trauma. They are also durable and can last several years with proper care. However, they are usually more costly than store-bought options.
Store-bought mouth guards, on the other hand, are readily available and generally cheaper. However, they are not customised to an individual's teeth and may not fit as comfortably or securely as custom-made guards. Store-bought guards are also less durable and may need to be replaced a few times a year.
When deciding between custom-made and store-bought mouth guards, it is important to consider factors such as cost, comfort, durability, and the level of protection required. Custom-made guards offer superior comfort and protection but come at a higher price. Store-bought guards provide a more affordable option but may not fit as well or last as long.
It is worth noting that the materials used in both custom-made and store-bought mouth guards can vary, and it is important to ensure their safety. Some mouth guards may contain harmful chemicals such as Bisphenol A (BPA) and phthalates, which can have negative health effects. It is recommended to consult with a licensed dentist or dental supply store to ensure the mouth guard is made from safe and approved materials.

Potential health risks of chemicals used
It is important to be aware of the potential health risks associated with the chemicals used in dental guard plastic preparation. Here are some key points to consider:
Bisphenol A (BPA) is an industrial chemical that has been widely used in plastic manufacturing since the 1950s. The concern with BPA is that it can leach into the body and cause potential health issues. Studies have suggested a link between BPA exposure and adverse health effects in infants and adults, including impacts on the brain, diabetes, and heart disease. While the threat of BPA is still debated, with some arguing the risk is low, it is important to be cautious, especially when it comes to dental products.
Phthalates are another group of chemicals used to make plastics more durable. The health effects of low doses of phthalates are not yet fully understood, but some research indicates that exposure may damage the liver, kidneys, lungs, and reproductive system. Phthalates can be released into the environment and potentially expose humans, so it is important to check with your dental guard provider about the presence of phthalates.
Methyl Methacrylate (MMA) is a chemical used in the manufacturing of resins and acrylic plastics. MMA gained a negative reputation due to its use in liquid form for acrylic nails, which caused skin reactions. While manufacturers of dental guards containing MMA claim that the "cured" form cannot leach into the body, there are MMA-free options available for concerned individuals.
Silicone, a lab-made chemical composed of silicon, oxygen, carbon, and hydrogen, is sometimes used in flexible, plastic dental guards. Experts consider silicone to be safe and unlikely to be toxic due to its chemical stability. However, it is important to note that some individuals may have an allergic reaction to silicone, resulting in a red rash.
In addition to these chemicals, there is ongoing research into the potential release of microplastics from dental guards. While the extent and health implications are not yet fully understood, it is important to stay informed about emerging findings and consult with dental professionals for personalized advice.
When preparing dental guard plastic, it is crucial to prioritize safety and choose materials that are rigorously tested and approved. Consulting with a licensed dentist or dental supply store can help ensure the use of safe and appropriate materials, minimizing potential health risks associated with harmful chemicals.

How to make your own
Mouth guards are dental appliances that fit over your teeth to protect them from damage caused by teeth grinding, jaw clenching, or sports-related trauma. They can be custom-made by a dentist or bought from a store, and they are typically made from plastic-based materials such as acrylic, polyvinyl chloride (PVC), thermoplastic elastomers (TPE), and ethylene-vinyl acetate (EVA) copolymers.
If you want to make your own mouth guard, you can create a DIY night guard by purchasing a stock night guard or mouth guard from a drugstore, sports store, or online retailer. Boil some water and place the mouth guard in it for about 30 seconds to soften the material. Then, let it cool slightly for a few seconds before pressing it firmly against your teeth. You can choose to fit the guard to either your upper or lower teeth, whichever is more comfortable for you. The molding process should take about 30 seconds.
After you have achieved a comfortable fit, trim any excess material from the night guard to reduce bulkiness. Scissors can be used to cut away the extra plastic, and sandpaper can be used to smooth out any rough edges that remain. It is important to note that DIY guards may not offer the same level of precision, durability, or protection as custom-made guards, and they might cause discomfort or dental issues due to a poor fit.
Additionally, when creating your own mouth guard, it is essential to be aware of the potential health and safety concerns associated with the materials used. Some mouth guards contain harmful chemicals such as Bisphenol A (BPA), phthalates, and methyl methacrylate (MMA), which have been linked to negative health effects. It is recommended to check with your dental provider about the ingredients used in your mouth guard and prioritize your health and safety.

Safety and durability
Safety:
It is important to choose the right materials for your dental guard to ensure safety. Some materials used in dental guards, such as Bisphenol A (BPA) and phthalates, have raised concerns due to their potential health risks. BPA is a chemical used in creating hard plastics, and exposure to it has been linked to various health issues, including heart problems, diabetes, and brain and behavioural issues. Phthalates are chemicals that enhance the durability of plastics, but exposure to them may cause damage to the liver, kidneys, lungs, and reproductive system. It is best to opt for dental guards that are explicitly labelled as BPA and phthalate-free.
Another material to consider is methyl methacrylate (MMA), which has a history of causing skin reactions in liquid form. While manufacturers of dental guards containing MMA claim that the cured, non-liquid form cannot leach into the body, there are MMA-free options available if you have concerns. Silicone-based dental guards are also considered safe and non-toxic, although some people may experience allergic reactions, resulting in a red rash.
