Doctors where i preside suggest every 6 months due to decay and bacteria buildup.
Personally, i dont buy a new one until my bristles are ruined or there is obvious damage to my toothbrush. Regardless, i buy a new toothbrush yearly.
Im curious , what factors do others take into account when buying a new toothbrush?
