Health Tips
1.Please ensure that your lip frenum (labial frenum)attachment is normal and is not the cause of this gap as if that is causing this gap then you need to get the attachment corrected simultaneously.
2.Also get one X ray done for this region to look for the supernumerary tooth (extra tooth)which may be lying underneath your gums and could have led to this gap formation
