...how do you handle it?

This used to happen with our son, but he grew out of it. Hoping our daughter does the same, as it still happens now and then!

We usually try to make toothbrushing more fun with special toothbrushes, brushing together, singing songs, etc. We also always let the kids brush their teeth first, and then we "check" it by rebrushing their teeth. But when nothing works and the kids absolutely refuse to let us brush their teeth, we would either wait and try a little later... or if need be, force a quick tooth brushing. Otherwise if I let it slide once or twice, then the kids start refusing to brush their teeth more. Now it's non-negotiable, and there have been a lot less incidents.

When your LO absolutely refuses to let you brush their teeth, how do you handle it?
