Since you will be introducing chemicals to the oral mucosa, there may be some irritation. Starting slow with take home trays and increasing exposure should give you an idea of your threshold. A well fitting tray system (not the flexible type found in most dental offices) should contain the gel and therefore limiting leakage and exposure to the gel.
