Many people continue using the same toothbrush for many months without knowing the risks. Dentists recommend changing toothbrushes every 3 months, but this habit is often ignored due to carelessness or lack of awareness. Old toothbrushes lose their cleaning power as bristles wear out and become ineffective. They also gather bacteria which can cause gum infection, tooth decay, and mouth ulcers. This problem is commonly seen among children, teenagers, and adults, especially in areas where dental health education is low. Even educated people sometimes forget or avoid replacing their toothbrush on time. This can lead to expensive dental treatments later.
Awareness campaigns in schools, homes, and public places can help promote this simple but important habit. Changing a toothbrush every 3 months is a small step, but it protects us from big dental problems.
