Say this louder for the people at the back. Teeth are NOT supposed to be killer white. You can get them white yes, but with chemicals that will be not very nice to the enamel on your teeth. Just brush your teeth, have a dentist clean and possibly whiten them every now and again. Natural teeth are gorgeous, even wonky ones..... Full of character! Tik tak teeth are not for me.They think their teeth are yellow cos they are used to seeing those ridiculous bright white teeth by their Turkish dentist. Teeth are not supposed to be pure white.
