How Often Should You Change Your Toothbrush?

Most people take their dental care seriously by brushing their teeth daily. It is very recommendable. However, the thought of replacing the toothbrushes rarely crosses their mind. We constantly focus on getting rid of the bacteria in our teeth and forget the important part, the germs left on the toothbrush. Brushes are not meant to last forever. Over time, they go through wear and tear. Knowing when and how often to change toothbrush will improve your dental hygiene significantly.

How Often to Change Toothbrush

Dentists recommend you brush your teeth at least two times a day. While you are busy observing oral hygiene, the toothbrush undergoes wear and tear. How do you know it is time to throw the old or tattered toothbrush away? Doctors and toothbrush manufacturers advise clients to change toothbrush every 12 to 16 weeks to avoid bacteria build-up. It also helps you maintain a consistent optimal oral hygiene standard. Other circumstances that may force you to replace toothbrush sooner include if the bristles have become soft, someone else has mistakenly used your toothbrush, or if it falls in the garbage. Also, if one family member suffers from a bacterial infection, it is wise to replace everyone’s toothbrush to prevent the spread. If you can’t recall the last time you replaced your toothbrush, it is time you do so.

A toothbrush can only function efficiently if it is in good condition. Changing your toothbrush more often will help you prevent oral-related bacterial and fungal infections.

This makes the mouth vulnerable to harmful micro-organisms and infections. Changing your toothbrush regularly will protect your enamel and gum tissues.

These can lead to tooth decay, cavities, bad breath, and gum diseases. Dentists recommend we replace toothbrush every 3 to 4 months will minimize the risks of these dental conditions.
