Why daatho and not daath here
Because it is oblique case plural for a male plural adjective ending with a consonant (hope my English is ok)
Do we need को after दांतों because दांतों is the direct object, or is it there for another reason?
Ko means at here
It accepted मेरे दाँत देखो for me. I don't know whether that's an error though.
I think it should be accepted without the को
