The toxicity of occlusal splints?

Hello, Doctor.
I am currently experiencing issues with temporomandibular joint (TMJ) dysfunction and have been using an occlusal splint for treatment.
However, during a previous adjustment of the splint at the hospital, the doctor heated and molded it.
During the adjustment process, I came into contact with the vapor released from the heated splint.
Although I rinsed my mouth immediately, I still swallowed some of it, which has left me feeling anxious.
I would like to know if this could have any adverse effects.
Additionally, with the long-term use of the occlusal splint at night, is there a possibility of ingesting toxic substances? I tend to be sensitive and anxious about such matters due to my hypochondriacal tendencies.
I hope you can provide some clarity.
Thank you.

Hello: The material of the occlusal splint is acrylic resin, which contains toxic organic monomers in its uncured liquid form.
However, due to the low concentration and relatively mild toxicity, most individuals can tolerate it.
(Modern dentistry has a history of nearly 300 years; if it were truly highly toxic, it would not have been used so widely and for such a long time.) If you are feeling anxious due to psychosomatic issues, it is advisable to discuss this with a psychiatrist.
However, not wearing the occlusal splint may worsen temporomandibular joint issues.
Sincerely, Lin Chia-Yung, Department of Dentistry, Taichung Hospital, Ministry of Health and Welfare.

More Info

When it comes to the use of dental splints, particularly occlusal splints for temporomandibular joint (TMJ) disorders, it is understandable to have concerns about potential toxicity, especially if you have experienced exposure to heated materials during the adjustment process. Let’s break down your concerns and provide some clarity on the safety of dental splints.

Firstly, dental splints are typically made from biocompatible materials, such as thermoplastic polymers, which are designed to be safe for oral use. These materials are chosen specifically because they do not leach harmful substances into the body under normal conditions. However, when these materials are heated for adjustments, there is a possibility that some volatile organic compounds (VOCs) could be released. While the immediate exposure you experienced during the adjustment may have caused some anxiety, it is important to note that most dental materials are tested for safety and are regulated to minimize any health risks.

If you inadvertently swallowed a small amount of vapor or liquid during the adjustment, it is unlikely to cause significant harm. The human body is generally capable of handling small amounts of foreign substances, especially if they are not toxic in nature. However, if you experience any unusual symptoms such as nausea, vomiting, or persistent discomfort, it would be prudent to consult a healthcare professional for further evaluation.

Regarding the long-term use of occlusal splints, there is minimal evidence to suggest that prolonged wear could lead to the ingestion of toxic substances. The materials used in dental splints are designed to withstand the conditions of the oral environment, including exposure to saliva and the mechanical forces of chewing. Regular cleaning and maintenance of the splint can further reduce any potential risks associated with bacterial growth or material degradation.

For individuals with health anxiety or hypochondriasis, it is common to feel heightened sensitivity to potential health risks. It may be beneficial to discuss these feelings with a mental health professional who can help you manage anxiety related to health concerns. Additionally, maintaining open communication with your dentist about your worries can provide reassurance and help you feel more comfortable with your treatment plan.

In summary, while it is natural to have concerns about the safety of dental materials, the risk of toxicity from properly manufactured and maintained dental splints is low. If you have ongoing concerns or experience any adverse symptoms, do not hesitate to reach out to your dentist or a medical professional for guidance. Regular check-ups and discussions about your treatment can help alleviate anxiety and ensure that your dental health is being managed effectively.
