In general, I don't think one doesn't ever not need lessons any more. A teacher provides an objective point of view. I am aware of top working pros who have gone for lessons with other working pros to problem-solve.
BTW, I'm neither a working pro, nor a trumpet teacher (although I used to teach privately), nor do I not need lessons anymore.
