Unless you and your dentist have worked out something different, dental bonding is usually not included with your Invisalign costs. Every dentist is different, so it really depends on your specific case. In my office, dental bonding is billed separate because it is way more labor intensive than adjusting Invisalign trays. It really depends how much bonding you need and how long it takes the cosmetic dentist that is doing it. In my photo section in my Real Self profile, I posted a photo of dental bonding on anterior teeth. That particular case took me more than an hour to apply bonding to 6 teeth. If you are talking about just one tooth and it is minor, then the price may be very cheap. I hope this helps.
