So the highest was about 8 ppm. That doesn't really alarm me.
I used to design and perform trace metal assays on incoming raw materials for a factory that made supplements out of powdered botanicals. A typical specification would say "no more than 20 ppm lead". Soil naturally has around 10 ppm lead, so it ends up in practically every plant.
Also think about the doses involved here. How much toothpaste do you consume (swallow) each day. A couple milligrams? Now compare it to the amount food you consume.
Toothpaste would be one of my last concerns.
It does make me question the common advice not to rinse out after brushing though.
Could rinse with mouth wash work. I assume, perhaps naively, it's less likely to have lead, and it would keep the fluoride present.
Mouthwash has a much lower fluoride content than toothpaste, so using mouthwash is still removing the fluoride that brushing applied to your teeth. Though I’m not an expert on this, I’m sure there are studies already comparing these two methods.
If you're on city water in the USA, we thankfully have flouride in the water supply. Unless you're in one of those places where the local government took it out.
it got banned across my entire state
Hell yeah,
