I remember seeing this movie when I was a kid. Like the 1990s maybe. The woman had her tongue cut off by a man and then later she is kissing that same guy with the healed severed tongue. I feel like that woman had blonde hair (maybe) and the guy might have been a serial killer. Perhaps her husband? I don’t know, all that sticks out is the tongue being gone. I also feel like maybe the woman was evil after that, she may have killed the man?? It was a color movie and in English of course
This is “The Dentist” (1996), or possibly its sequel “The Dentist 2”.
