Is there a better option than composite fillings?

I had bad staining on my front teeth. My dentist decided at my last appointment that he would cover the two stained teeth with composite fillings, however my gums started bleeding mid treatment so he stopped saying he would have to redo it at next appt. when I went to appointment today (2 weeks later) he said the discolouration on the filling is due to me smoking, but it wasn't the right colour to begin with, is he right and if so is there a better option than composite fillings?
