Toothbrushes should be thoroughly rinsed with water after brushing.  Store toothbrushes in an upright position and allow them to air dry.  Replace your toothbrush every 3 months or when bristles are frayed and worn.  Replace toothbrushes after illness and do not share your toothbrush.  Call Dr. Nadine Hutchins 970-242-7373 with any questions.
