Managing allergies to aligner materials can be challenging, but with the right approach, it is entirely possible to continue orthodontic treatment safely

Symptoms like burning, hives, or persistent irritation in the oral area following aligner use may signal an allergic reaction

While aligners typically use FDA-approved thermoplastics like TPU or PETG, certain people react not to the base polymer but to stabilizers, colorants, or lubricants introduced during fabrication

Begin by scheduling a visit with your orthodontic provider

Avoid discontinuing aligner use unless directed by your clinician, since pauses may delay progress or require costly corrections

Your orthodontist can examine the exact polymer composition of your aligners and suggest compatible replacements

A growing number of companies now provide aligners formulated without known allergens, using safer polymer combinations

In the meantime, maintain excellent oral hygiene

Use lukewarm water and a non-abrasive brush to gently scrub your aligners after removal

Steer clear of abrasive pastes, bleach-based soaps, or alcohol rinses, as these may accumulate and provoke reactions

Clean your hands thoroughly before inserting or removing aligners to prevent transferring allergens

A professional allergy screening, such as a patch test, can determine if the reaction stems from the aligner or an external substance

When sensitivities cannot be resolved, your provider may transition you to a non-plastic orthodontic solution

Some patients find relief with non-prescription creams or pills, but self-medication risks masking underlying issues

Maintain a detailed log correlating symptom outbreaks with your daily routine, including cosmetics, dental products, and foods

The culprit may be your toothpaste, mouth rinse, or even your lipstick—not the aligner material

Sharing this information with your dentist can help pinpoint the cause

Remember, allergies are manageable

With careful communication and attention to detail, you can complete your orthodontic journey without compromising your health

Protecting your health is the foundation of successful orthodontics
