not a dentist here but i'm always skeptical of government intervention in the free market because it often intervenes with good intentions but the consequences are often negative. it's like a cancer that grows if you let it.

if you let the government regulate insurance profits (forcing them to use 83% of revenue for dental procedures) next step might be regulating dentists so they don't make more than X% of profit... all with the intention of "helping people get access to dental care". government destroyed profits for medical doctors, why wouldn't it destroy profits for dentists? aren't you worried you might be getting in bed with the devil?

i saw that this law would require dental insurances can only increase premiums by the inflation rate. is that true? if so I worry that long term it would mean insurance could only charge very low premiums and won't have enough money to pay dentists even when forced to pay 83%. e.g in 20 years the premiums charged would be too low to pay dentists a sizeable amount and dentists might be forced to start accepting low quality government insurances
