Banning more than one daily triple cheese burger would be net benefit to society as well. Likely more than we’re getting on dental cost savings. I doubt most would be okay with that though.
If you have strong evidence for your proposal, I haven't come across it in my literature reviews.
The only food I am aware of that has strong evidence that it contributes to poor health outcomes is sugary sodas. (The only other nutritional thing that consistently shows a negative impact on BMI is dieting: for everything else, populations are too heterogeneous for effects to be consistent. There are people whose combination of genetics + lifestyle make two or more triple cheese burgers a day a perfectly healthy diet.)
Outright bans and limitations on size of soda cups were both struck down by the courts, but soda taxes have been an effective public health intervention that reduce consumption and improve health outcomes: https://www.frontiersin.org/journals/public-health/articles/... And they do get widespread support among technocrats.
