We Must Change Toothbrush After Three Months, Here is Why

For good hygiene, we must change the toothbrush after 3 or 4 months. Using the same brush for many months and for a year could be harmful for the teeth.

You must change your toothbrush every three to four months because worn out bristles are less effective at cleaning teeth and the brush can store bacteria, viruses and fungus that can lead to oral infections.

Additionally, older toothbrushes have higher concentrations of mold, fungus and microbes that might harm your oral health.

Also, after about three months, bristles get frayed and lose their hardness, making them unable to properly remove plaque and food particles from your teeth and gums.

When kept in moist conditions, toothbrushes can serve as a haven for bacteria, fungi and viruses. Gum disease and poor breath can be caused by an unclean toothbrush. (Disclaimer: Given the input is on an information basis, please seek professional advice.)
