For me it is about age + price
Full upper mouth of dentures cost 3,500 baht vs 7 implants cost 200,000 baht this was a few weeks ago.
Age 74 cannot see the point of spending all that... 2003/4 had 3 crowns and 2 bridges on posts, so lasted over 20 years cost back then 60,000 baht, these days appears the options are dentures or implants
Problem as you get older your gums shrink and whatever you have may well not fit well after time..... Thai friend has just had to have his Implant re-down after 5 years - 5 visits + 180.000 baht bill
so if when I get them my 3,500 baht dentures need replacing in a few years it will not be a big outlay........ at moment all 5 crowns have fallen out + my 3 own teeth have broken off, so far 2 weeks ago had 1 root removed, dentist say's better to have 1 x root removed every 3 weeks.
