When is the best time to replace your toothbrush?

Who among us does not use a toothbrush on a daily basis? But have you ever thought about how long it takes to change it?

In this context, dentist Hajra Sarwar provided some advice on the appropriate time to get rid of your old toothbrush.

Every 3 months or sooner

She said, "It is recommended to replace the toothbrush every 3 months, or earlier if the bristles are worn out. Worn out bristles are less effective in cleaning the teeth and gums," according to the British newspaper "Mirror."

She also added, "If you suffer from a cold, it is wise to buy a new toothbrush when you get better, to prevent any chance of getting sick again."

Electric brush

For persons who use electric toothbrush heads, she confirmed that “Similar to the manual toothbrush, it is recommended to replace it every 3 months, or earlier if its bristles are corroded.”

It was also directed to choose an electric toothbrush equipped with a pressure sensor, and to make sure to clean the base of the handle regularly to stop the accumulation of toothpaste and water.

Always adhere to the manufacturer's instructions for caring for the smart device.


As for interdental brushes, she advised replacing them every 7 to 10 days, or sooner if the bristles appear worn out, or if the wire begins to deform. They can wear out quickly, especially with regular use.

She concluded with a recommendation about mouthguards, saying, “If you use a mouthguard while exercising or to treat teeth grinding, replace it as needed or according to your dentist’s recommendations. Check it regularly for signs of damage.”
