I Am Very Worried About my Veneers. They Have a Very Rough Edge at the Seal Point on Top. Can Bacteria Get in There?

My dentist say no, they are fine. Really? Also I have a bright red sore spot between the two front veneers, on top of the roof of my mouth where the tooth meets the gum. The sides of my teeth are razor sharp and I have popping sounds (as if air is inside my veneers) when I push my tongue gently against the 5 veneers. In other words it's all a mess and my dentist says it's all good. What can I do?
