Is it obligatory to inform a suitor about losing a tooth and replacing it with a prosthetic one, especially since there is no direct communication between the two parties, and it is preferable that such information be exchanged only between the two parties?

May Allah reward you for your eagerness to deal with your fiancé according to Islamic law, and we ask Allah to complete your marriage with goodness. Such a defect does not necessitate informing the fiancé about it, and you bear no responsibility for not informing him.
