i recently had porcelin crowns done on teeth 6,7,8,9,10 and11. no. 6 is a little larger and higher than my original tooth and is pointing in a little bit. no. 10 is shaded with a tint of gray ( like my temp was on no.10) the dentist said ,don’t worry your new crown won’t have the grayish tint. BUT it does!! i now have two “black holes” at the gumline between teeth 6,7,and 8. and now smallish gaps between each of my new teeth which lead to alot of saliva that forms in my upper gum area.i did not have this problem before and do not see why after spending the money i did ,why i have it now.i am aware that gum lines receed as you age (56) but, again i did not have any of the “problems” before,so why do i have to accept them now. i am constantly wiping my upper gum to rid of foam and bubbles from the saliva. and this morning i left a phone message with them and asked for an appt. to polish the back of no. 9. they called be back and said the dentist cannot do anything about the “color” of no.9,.she obviously misunderstood my message but said, if you want to replace no.9 due to the grayish tint then you have to pay for it yourself. WHAT GIVES!!!! THANK YOU.
