That Starmer fella...

"Guys! We employed a bunch of people with consciences! We can get them to do a load of shit that they're not paid to do by leaning on their sense of morality! WAHEY!"

The tories made the exact same arguments in the 1970s when they took free milk away from early years school children. But they didn't give a shit about teacher workload. They just wanted to make a political point and save a bit of money.

The teachers incidentally were against the removal of free milk, despite the additional overhead it took out of their day to distribute it.

I've a feeling if another leader came up with this policy you'd be in favour of it.

EDIT: And let's not pretend teachers aren't already doing this. From the BDA:

1. 83% of secondary teachers say they or their school have given
   students toothbrushes and toothpaste. 81% said there are children in
   their school who don't have regular access to supplies
   
2. 40% said this leads to students being socially excluded by their
   peers because of oral hygiene issues. Half report children isolating
   themselves. One third have witnessed bullying directly
   
3. 25% say children miss school because of poor oral hygiene. Three
   quarters (74%) said children who don't have regular access to oral
   health products have discoloured teeth. Half said children had
   noticeable tooth decay. 30% noted children in dental pain or
   suffering from halitosis
   
4. Nearly a third (31%) of teachers who witness poverty in the
   classroom said it affected their mental health. 1 in 4 are kept
   awake at night worrying about their students' wellbeing. 38% report
   feeling helpless.
