Dentist guessed the sex - anyone else's dentist?

I went to the dentist and they have a "test" for their pregnant patients to predict sex. Anyone else ever heard of this (maybe my dentist is unique/crazy)? They had me touch my tongue to the roof of my mouth and depending which side the blood flows on the underside of my tongue determines the sex. Right side girl, left side boy - or vice versa, I forget

They guessed girl with DD and this time guessed boy, we'll see!
