Typical costs in Ontario, Canada for checkup and cleaning is CA$ 150 (what I've generally paid the last few years†):

I don't think dealing with "cavities" (plural) would be cheaper. And as the folks in the city of Calgary (AB) found up, cavity rates will go up:

Windsor (ON) decided to start adding it back in for public health reasons:

> According to the latest oral health report[1] from WECHU, the percentage of children with "decay and/or requiring urgent care" in 2016/2017 increased by 51 per cent compared to 2011/2012.

> "The most alarming trend was the three-fold increase in the proportion of children eligible for topical fluorides," the report reads.

† Many years I only go once a year, even though official advice is twice, since I've thankfully generally not experienced many dental problems.
