Have you tried oil pulling?

I tried oil pulling with olive oil a few months ago but it made me gag so I stopped. I've started again with coconut oil instead which I can tolerate and it feels like it's doing something but idk how effective it actually is long term or if it's all hype?

My routine is oil pull for 20 minutes first thing in the morning with just a teaspoon of oil then brush my teeth and have breakfast etc. brush teeth at night and use mouthwash plus floss. I've always had sensitive teeth and my enamel isn't great (I get cavities from fruit) so I'm hoping this routine might help, my sensitivity is down a bit bit idk if it's placebo or what.

Any experiences with oil pulling?
