For many people, changing toothbrushes is not a priority like it is to restock the fridge, buy new skincare products or empty the trash. It's something that only crosses our mind when the old toothbrush completely wears off.
But that’s not how things should be! Good dental health starts with using a clean and relatively new toothbrush. You also need to brush at least twice a day. If you’re confused about what “relatively new” means, below is our informed analysis of how often you need to replace your toothbrush.
When to Change Your Toothbrush
The American Dental Association recommends replacing your toothbrush every 3 months. The association based their advice on various studies that showed toothbrush bristles started degenerating after 3 months, which means they start becoming ineffective in getting rid of plaque and food particles in the teeth.
Moreover, toothbrush bristles can attract and harbor germs and bacteria, which can threaten your dental health. This buildup, and the health issues it can cause, may prompt you to change your toothbrush even before the recommended time. For instance, you are advised to replace your toothbrush if you happen to get a sore throat or any other bacterial infection, even if you’ve only been using it for a week. This simple act helps to avoid re-infection.
