If you are changing $1000, an extra 50 satang adds up to 500 baht, which may not warrant going all over town, but would certainly cause me to seek out the exchange place if within a reasonable distance and cost.
The materials cost much the same, but the labour and caps would be significantly less in the cheaper countries. You've also got to check that inferior materials are not being used. But the information about the fixed dentures is useful. Can anyone attest that the pins work at holding the lower denture?
Huge price difference. I don't have dentures, but have researched them, and top dentures tend to sit quite happily in the roof of your mouth and are not that difficult to negotiate, whereas lower dentures are a different story altogether. Those with direct experience may however have a different tale to tell.
