Best whitening product that blinded the sun whenever you smiled lol
Jenever is good. A 100€ dental cleaning does better.
A toothbrush.
You have to use it twice everyday at least and buy this special paste for it though…. sometimes I wonder if there is a better solution
Listerine white strips. I notice a difference after only using one. Also, Rembrandt Intense Stain toothpaste.
use the kind with the trays. the other kinds just slip off your teeth. they all work, it’s the same stuff used in the office but weaker.
good ol timeie tooth powder if you can find it I order my online, its hard to get but it use to be comin product in the 60s 70s 80s.
Good maintenance which includes correct brushing twice a day.
