Your toothbrush will eventually wear out, particularly if you’re cleaning your teeth twice a day for two to three minutes every time. Your dentist recommends that children and adults change their toothbrush every a quarter. If you happen to be using an electrical toothbrush, be totally sure to read the directions because you may not need to change toothbrush heads as often. Patients with gum illness are prompted to change their toothbrush every four to six weeks to keep any bacteria from spreading. After brushing, wash your toothbrush with warm water to kill germs and keep the bristles clean. If you’ve been sick, be totally certain to switch your toothbrush straight away.
