Can I avoid a crown for these two premolars? (Photo)

Hello I’d like to ask can I avoid a crown for those two premolars ? They both had root canal and my dentist told me that she would prefer to make me a crown for the last premolar but that I could have a onlay for the first premolar. Do you think its possible to have onlay or inlay for both or it looks like its too damaged ? Heres a picture.
