The bristles of the toothbrush cannot reach the adjacent tooth surfaces between the teeth to clean them
If the adjacent tooth surfaces are not cleaned
the dental plaque that is adhered to the surfaces will release toxins
causing the gums in the area to become inflamed, red, swollen and bleed easily
resulting in gum disease
Therefore, apart from daily toothbrushing, you need to floss everyday to clean the adjacent tooth surfaces
in order to prevent gum disease
