Mixed colors: Sometimes you need to mix colors of tooth colored filling material to match the existing tooths color if u have a white and grey stripe on the tooth seen the dentist who did the filling to modify the restoration.

Ask treating Dentist: Sometimes when an old silver mercury amalgam is removed the gray stain is left behind. This could give the appearance of a blended gray and white filling. The best person to resolve this with you is the dentist who you went to for your filling.
