How long to use a toothbrush?

Hai akalya
Be sure to change your toothbrush, or toothbrush head (if you're using an electric toothbrush) before the bristles become splayed and frayed. Not only are old toothbrushes ineffective, but they may harbor harmful bacteria that can cause infection such as gingivitis and periodontitis. Toothbrushes should be changed every three to four months. Sick people should change their toothbrush at the beginning of an illness and after they feel better Hope is help

Dear Akalya,

I had recently visited the dentist for tooth removal. He suggested changing toothbrush atleast every 2 months, and not to use more than that.

When the bristles start looking frayed,its time to discard your toothbrush.
Usually this happens in 1-1/2 months if u brush regularly day & night.
Too soft a toothbrush is also not advisible.

 

Hi

My dentist said you have to change toothbrush every three months.

bye.

 

Many toothbrushes today have a part of them that changes color as it is used (eg. Oral B). If you are uncertain, that is the way to go. Personally, I toss mine when the bristles start to fray.
