when having my implants [17] done in India @ one third the price in UK, the guy dropped one of the screws in my mouth, he promptly pressed a lever which jerked the chair up so I could spit it out, but instead as I shot up I swallowed it. Big panic as he should have apparently put a net in my mouth to prevent this, they hospitalised me and xrayed me gave me oatmeal and banana to eat but it took four days to go through my system and what they were worried was it would perforate my bowel, well CS did not tell me this and when I saw how big the screw was I nearly passed out, rang no 2 son at home in UK he said it could only happen to you mum ! hospital gave me the screw after it had been sterilised and dentist paid the hospital bill and CS negotiated a reduction in final bill. Having said that they do look good, but would I go back and have the bottom teeth done ? no thanks.
