Plaque buildup is the cause of tooth decay. If left untreated, it can lead to gingivitis or gum disease. Over time, it can progress to periodontal disease and tooth loss. Using a toothbrush that is more than 3 months old with worn bristles will not be able to effectively clean plaque from the tooth surface.

Bacteria and viruses can live up to three days on a toothbrush. Although the body has built up antibodies to fight them, if you use an old toothbrush and damage your gums, the risk of oral diseases is quite high.

To avoid bacteria and fungus from accumulating on the toothbrush, after each use, wash thoroughly, shake vigorously under running water, and keep the toothbrush upright to dry. It should be inserted into a separate slot to avoid touching other people's toothbrushes.

Remember to change your toothbrush after a cold, flu, or infection to avoid the risk of reinfection. Also, replace your toothbrush sooner than 3 months if the bristles are worn or frayed.
