Is it time to change your toothbrush?


You should change your toothbrush every 3-4 months for hygiene. However, if you have just recovered from an illness it is advisable to change your toothbrush immediately. Since many diseases and illnesses can be transmitted through the mouth and saliva, it's possible that your toothbrush still has a virus or bacteria on it. Replace it with a new one to avoid the spread of germs and cross-contamination.
