When A Tooth Brush Can Be Changed?
- A tooth brush can be safely used until it's fibers become hard and brush fibers spreading. When brush fibers becomes hard and start spreading we should change our tooth brush. Continuous use of a harden and spreading tooth brush cause more abrasion of tooth and puncture of gums and bleeding of gums. At long time use of this can cause gingival recision and thermal sensation of teeth.
- A brush can be safely used approx 20 to 30 days.
