Invisalign plastic sensitivity management is a clinical protocol at Enamel Dentistry Manor. For our patients who have chemical or other material hypersensitivities, our team utilizes medical-grade, USP Class VI SmartTrack polymers for your aligners. This hypoallergenic material is free from BPA, BPS, latex, and gluten. SmartTrack material is shown to have no cytotoxic effect on cells in the mouth [1] (Nemec et al., 2020). This ensures that your orthodontic tooth movement occurs without triggering systemic inflammatory or allergic responses in patients.
Choosing to wear a plastic aligner for 22 hours a day can feel daunting for the wellness enthusiast or the preventive planner near Manor. You may worry about chemicals leaching into your body or waking up with an itchy and inflamed mouth. Nobody wants to invest in a straight smile, only to suffer from a chronic allergic reaction. At Enamel Dentistry Manor, we prioritize your health. The advanced materials utilized in your aligners are thoughtfully engineered to be inert. This helps you to reach your cosmetic goals without compromising your body’s natural balance.
Plastic sensitivity, or contact stomatitis, is a rare immune response in patients with a hypersensitivity to specific plastics (polymers) used in dental appliances. Medical-grade polymers such as polyurethane and PET-G are designed to withstand mechanical stress while remaining biocompatible [3] (Ferreira et al., 2025). Invisalign consists of a patented multilayer SmartTrack material. Because this material is medical-grade, it does not contain common allergens found in household plastics.
It is common to experience mild discomfort when you start a set of new aligners near Shadow Glen. However, knowing the difference between normal biological movement and oral sensitivity is key.
Our team uses AI-assisted oral monitoring to track your gum health during your orthodontic treatment. If you experience any of these symptoms, we are able to adjust your wear schedule or provide protective barriers to ensure your comfort.
SmartTrack is not just clear plastic. It is a specialized polymer that was rigorously tested to earn a Class VI USP rating. This is the same safety standard required for medical implants and heart valves.

In Manor, a comprehensive Invisalign treatment typically ranges from $4,000 to $6,500. For patients with high plastic sensitivities, this investment provides a return on health that generic options are unable to match. We know Manor families are balancing budgets while living near the Hwy 290 corridor. To make this medical-grade care accessible, we offer:
The attachments are made of dental composite resin, the same material used for tooth-colored fillings. If you have had a filling before without a reaction, you are likely safe. We can perform a small “test bond” if you have extreme chemical sensitivities.
No. Invisalign trays are 100% metal-free. Making them an ideal alternative for patients who have a nickel allergy and are unable to wear traditional metal braces.
Itching can sometimes be a sign of trapped bacteria rather than an allergy. Try cleaning your trays in a 42,000 Hz ultrasonic cleaner. If the sensation continues, contact our Manor office for a professional clinical evaluation.
