Can You Be Allergic to Your Mouthguard? Causes & Symptoms

Can you be allergic to your mouthguard? While its possible, a true allergic reaction to mouthguards appears to be uncommon. If your night guard causes irritation, sensitivity, or discomfort, the cause may be related to the materials used, poor fit, or buildup on the appliance. Understanding what's behind your symptoms can help you find the right solution.

In this blog, we are going to discuss irritation and allergies, whether mouth guards cause allergies, other factors that may be causing your problem, and how you can protect your teeth.

Mouthguard Irritation vs. Allergic Reaction: What’s the Difference?

General Irritation

General irritation caused by a mouthguard can be attributed to some conditions such as improper fitting, cleaning, or usage of the oral appliance. According to Cleveland Clinic, an improperly fitted mouth guard might cause irritation on the gum, tooth, or jaw areas. Other causes may include pressure and friction on the gums, and contact wth chemicals in the cleaning product.

True Allergic Reaction

Unlike irritation that results from mechanical and chemical causes, an allergic reaction is triggered when the immune system reacts to a particular substance. The allergic reaction may occur when the body becomes allergic to some substances in dental products or oral appliances.

Can You Really Be Allergic to a Mouthguard?

Yes, some people can develop an allergy from wearing dental guards or mouthguards, although this is uncommon. If an allergic reaction occurs, it may present as contact stomatitis, an inflammation of the tissues inside the mouth caused by exposure to certain substances.

What is Contact Stomatitis?

According to DermNet NZ, contact stomatitis is a term used to define the inflammation that occurs within the mouth upon contact with a triggering agent. In some instances, the condition can occur in response to an allergen due to a reaction from the body's immune system.

What Materials in a Mouthguard Can Trigger an Allergic Reaction?

As the mouth guards are made from various materials, there might be cases where some people can be allergic or sensitive to some particular material used in the appliance. There have been various cases where certain dental materials have resulted in allergic contact stomatitis in individuals allergic to some materials.

Research on dental material allergies has identified substances such as latex and acrylates as potential triggers of allergic reactions in dental settings. This demonstrates that some ingredients in oral care products can lead to sensitization or allergic reactions in certain people. However, not all mouthguards use the same materials, and reactions may vary depending on the appliance and individual sensitivity.

Signs of a Possible Allergic Reaction to a Mouthguard

Possible signs of allergic reactions to a mouthguard may be as follows:

• Inflammation in the oral cavity
• Burning or itchiness feeling
• Swelling
• Pain and soreness
• Mouth lesions
• Pain even after cleaning the mouthguard

Because these symptoms can resemble irritation caused by a poor fit or inadequate cleaning, persistent or worsening reactions should be evaluated by a dentist or healthcare provider.

Other Common Causes of Mouth Irritation from a Mouthguard

In case the symptoms are not caused by allergy, then one of the following causes might be responsible for your condition:

• Ill-fitting mouthguard: A poorly fitting mouthguard can put stress on gums, cheeks, or teeth.
• Poor cleanliness: Fungi, bacteria, or dental plaque which is accumulated on the dirty mouthguard could irritate your mouth.
  
• Wear and tear: Damaged, cracked, or rough edges of the mouth guard can irritate the soft tissue in your mouth.
• Chemicals from cleaning products: Too strong or poorly washed mouthguards may have residues of chemicals left from cleaning products.
• Continuous use: Using the mouthguard for long periods of time can cause irritation, especially in case the mouth is dry.

What to Do If Your Mouthguard Is Causing Discomfort

In case the dental guard or mouth guard you have been using is causing you some discomfort, here are some approaches that can be used to solve the problem:

• Stop wearing your mouth guard for the time being if the problem persists or aggravates.
• Check the condition of your mouth guard.
• Think of using a mouth guard that suits you well and fits in properly and that is safe for sensitive people.
• Use an honest provider who reveals the composition of his products.
• Consult a dentist or healthcare provider if discomfort continues.
