Does Invisalign glue cause stains?

Dear meanu,Thank you for posting your question on RealSelf.  I will do my best to provide an answer with the information provided.Invisaling 'glue' or attachment bonding material does not cause staining.  Although, depending on your diet or habits, the attachments may turn yellow.  Once the attachment bonding material is removed, the discoloration will go away.I hope that this helps and best of luck.Dr. Jennifer StachelJennifer Stachel Orthodontics
