It is permissible for you to use gold teeth if the dentist you consulted is skilled and sees that it is best for you,
otherwise this is not permissible to use them. Further, when a person dies, gold teeth should be removed in order to maintain the (heir's) wealth and to avoid wasting money as the Prophet (peace be upon him) has stressed. However, if removing these gold teeth will cause the corpse to be mutilated or the gum to split, then they should be left. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
