Brushed my teeth with toothpaste does that destroy the last four fasting days?

I ve been Water Fasting for the last four days, but I've been brushing my teeth with toothpaste, I think I even swallowed some today. So is the last 4 days of fasting wasted?

Should I assume from here going into day 5 that it's basically starting on day one again?

A quick note I was a bit hungry today, had a stomach growl.

Or perhaps does it have little effect?
