Payment is typically handled directly by the dental office unless the payment terms specify "Cloud Direct Pay” or CDP. The booking agreement that’s linked to the booking, will specify the payment method as well.
When the office pays you directly, it can either be as an independent contractor (1099) or as an employee (W2). When you are paid through CDP, it’s always as an independent contractor (1099).
Taxes are not withheld when paid as an independent contractor (1099), so make sure that you set aside enough money from the payment in order to pay the tax when it’s due.
