My dentist made me a temp crown while we waited for a perm. The temp fit fine but when the perm crown came in, it felt huge. He started drilling and I noticed I could fill it hitting the men's in my top tooth. He took a small break and I noticed that he had flattened out my top tooth completely. Now I can no longer eat hot or cold things on that side. I can't even eat chips now! Any input on what to do would be great!
