In recent years, many people have become much more cognizant of potentially harmful chemicals contained in a wide range of plastic products. For example BPA (bisphenol A)- now essentially a household name- is a chemical used to harden plastics that can be found in water bottles, food cans, plastic containers, dental sealants, and many other manufactured commodities. According to WebMD, animal testing has raised concerns that BPA in large amounts could affect hormone levels as well as cause brain and behavioral issues, cancer, heart problems, and other conditions such as diabetes and ADHD. It is no surprise, then, that people often question whether dental materials and appliances contain BPA. Individuals who suffer from teeth grinding (bruxism) may be particularly concerned as teeth night guards are used directly in the mouth for long periods of time and experience a high level of wear-and-tear.
Luckily, teeth grinders can rest assured that our teeth night guards do not put them at risk of BPA exposure. All of our suppliers have confirmed that none of the products we use to create our teeth guards contain BPA. Therefore, BPA exposure is not a risk in teeth guards purchased online at ProTeethGuard.
Phthalates and Methyl Methacrylate (MMA)
Another concern that has been raised by bruxism patients seeking out a teeth night guard is whether the materials contain phthalates. The CDC defines phthalates as such:
“Phthalates are a group of chemicals used to make plastics more flexible and harder to break. They are often called plasticizers. Some phthalates are used as solvents (dissolving agents) for other materials. They are used in hundreds of products, such as vinyl flooring, adhesives, detergents, lubricating oils, automotive plastics, plastic clothes (raincoats), and personal-care products (soaps, shampoos, hair sprays, and nail polishes).
Phthalates are used widely in polyvinyl chloride plastics, which are used to make products such as plastic packaging film and sheets, garden hoses, inflatable toys, blood-storage containers, medical tubing, and some children's toys.”
In regards to their effects on human health, the CDC comments, “Human health effects from exposure to low levels of phthalates are unknown. Some types of phthalates have affected the reproductive system of laboratory animals. More research is needed to assess the human health effects of exposure to phthalates.” As with any chemical substance, concern regarding the safety of phthalates is quite understandable. More information on phthalates can be found on the CDC's website here: https://www.cdc.gov/biomonitoring/phthalates_factsheet.html. Our hard acrylic night guard does contain dialkyl phthalate, a plasticizer that gives the material its thermoplastic nature, but this particular phthalate is not deemed dangerous and is not to be confused with other chemicals with similar names. For those individuals concerned about phthalate exposure, we would recommend seeking out other alternatives different from our teeth guards.
We have received inquiries regarding the chemical MMA (methyl methacrylate). In the past, this chemical was commonly used in nail salons for the application of acrylic (fake) nails. The FDA received many serious complaints by salon-goers regarding the safety of this chemical, as it was causing severe irritation when applied directly to the skin and nail bed as a liquid. In response, the FDA prohibited its use in nail salons by the end of the 1970s. Beyond this, methyl methacrylate is used much differently for safer consumer purposes such as the creation of plexiglass, building siding, advertising signs, light fixtures, bathroom fixtures, and medical cement for bone replacements according to the EPA. These are much different scenarios, as these items are cured and sealed. MMA is a concern for individuals who come in direct contact with the chemical, such as workers who manufacture these products. Given the fact that some of our teeth guards are made using acrylic, it’s understandable that a bruxism patient might be concerned about MMA exposure. For those individuals concerned about MMA exposure, we would recommend seeking out other alternatives different from our teeth guards.
Gluten and Latex
According to Celiac.org, Gluten is a general name for the proteins found in wheat (wheatberries, durum, emmer, semolina, spelt, farina, farro, graham, KAMUT® khorasan wheat and einkorn), rye, barley and triticale – a cross between wheat and rye. Gluten helps foods maintain their shape, acting as a glue that holds food together. Gluten can be found in many types of foods, even ones that would not be expected.
Natural rubber latex comes from the sap of the rubber tree, Hevea brasiliensis, found in Africa and Southeast Asia. Allergic reactions to products made with latex develop in persons who become allergic (or sensitized) to proteins contained in natural rubber latex.
Pro Teeth Guard takes latex allergy and gluten sensitivity concerns very seriously and we have contacted our suppliers. They have confirmed that none of the materials used to make our teeth guards contain gluten or latex, so rest assured there is no issue in using a custom dental night guard from Pro Teeth Guard for those with gluten sensitivities or latex allergies.
