If you're talking about the missing part on the very tip, that's definitely not an issue. I will regularly dremel my problem birds past that point on their beaks safely, including one of my Greys. If my Greys beak was that overgrown, I will dremel it but I'm not advising you to do the same. You have to know what you're doing.
