In order to see your rewards in your wallet, first, you have to request a withdrawal from your Dentacoin account. The withdrawal option becomes available when your account is verified with CIVIC. See how to do it here: https://youtu.be/-iCofoHguco.
After verification of your account, you will see the time until your first withdrawal. When the counter goes to zero, you will be able to insert your wallet address and make the withdrawal. Note that first withdrawals go through a security check which may take up to 5 business days.
