Since we can’t get to a dentist in lockdown I’m noticing my lower teeth and getting really grubby - in between each tooth seems to be getting darker and looks awful. It doesn’t budge with standard cleaning. Any idea what I could try since it’s going to be months before I can get to see a dentist?
Try using interdental brushes if you don't already do so. They are readily available at most supermarkets. I recently bought a tin of Eucryl Toothpowder, also at the supermarket, and find it very good.
