1 weeks post. Will my black triangles fill in? (photo)

Just had my 6 upper front crowns of 16 years replaced last week and now I have a couple of very small black triangles that pass saliva and air through when speaking. While the look is a significant improvement, the feeling Is driving me crazy. Dr said to give it a month or so and they should close. Is this true? He didn’t seem too receptive to redoing. This is causing me significant emotional distress.
