I buy Dent-o-Care long head interspace brushes for cleaning between my teeth. They are not cheap, but since these brushes cannot be bought in shops anymore, I'm willing to pay the extra. I have had 25 years of service from teeth which would probably have fallen out by now without the use of specialised brushes. Dent-o-Care send my order by Royal Mail, and the brushes arrive next day. I recommend Dent-o-Care for the service I get as well as the quality of the brushes.
