Dear Bryanna, thank you so much for your quick reply. its really very informative and helpful. just wanted to let you know that I live in Pakistan (third world country) and sometimes in Australia. the dentistry work in Pakistan is good and verrrrrrryyyy cheap. the dental bridge i just put in is $240. Due to the reason of low cost and good quality, I was thinking to replace the bridge (which was a mistake I regret) with two separate crowns to increase the longevity of the abutment teeth, and replace missing tooth with some flexible partial denture like valplast. thanks
