how much does a new retainer cost?

You would have to call and ask them. Everybody is different.

Hi Miaha, the cost of the retainer will depend on the type of retainer needed and if the retainer is used to move teeth or to hold the position of the teeth. Please feel free to give us a call at 359-4480. We can make an appointment, at no charge, to discuss the best retainer for you and the cost associated with that service. We look forward to hearing from you! - The Braces Place
