i was quoted from a private dental clinic that polishing was
$80. after I told the dentist got a tiny fragment of my tooth came
out, he said my tooth are decaying, especially my wisdom tooth, who
may needed to be extracted out. He did some filing and polishing,
the costs is $230 in the end.
That is why it is good to get a degree in dentistry in NUS and
become a local dentist.
The intake is about 1/6 of that of medicine though, so go figure
