Tooth and Mouth Problems

I received 4 crowns on teeth 7,8,9, & 10. In July 2019. Teeth 8-10 were previously treated with root canals 10 years ago. I am now having issues with a bad smell when flossing especially on tooth 8. I was informed that the crown on teeth 8 is "sub margin". Do you recommend replacing the crown? Also, based on my x-rays is there anyway to tell if the crowns are all sub marginal? Aesthetically I do not like the appearance (too square, bulky, and white) but am now more concerned about the health implications . Lastly I was not warned that the crowns would flare.
