Improper bite after orthodontics. Does anyone know why I'm hitting my front teeth when I talk? (Photo)

I constantly hit my front teeth on my bottom teeth when I speak. My ortho doesn’t know why! He says my bite looks perfect but even that too, it feels crooked to me and I catch my back cheek on my right side when I chew. He wants me to wait until the bite settles to see if it fixes my issues. Why did he take braces off knowing I had these issues? I’m feeling regretful I let him take them off. Does anyone know why I’m hitting my front teeth on my bottom when I talk? Maybe I can share it with him.
