Do You Need to Change Your Toothbrush After Getting Sick? Here's How to Keep It Clean

JAKARTA - When we are sick, germs in the mouth can stick to the toothbrush. However, this does not always mean that you have to immediately replace your toothbrush after recovering. Although toothbrushes can contain germs, it is very likely that the germs will not make you sick again.

Reported from the Verywell Mind website, there are certain conditions where replacing toothbrushes, both your own and other family members. This is a safer option. In addition, how to properly care for toothbrushes is also very important to prevent the spread of germs.

When you have a cold, flu, COVID-19, or other infectious disease, viruses or bacteria can stick to your toothbrush. Some types of viruses, such as the flu virus, can even survive for several days.

If your immune system is working well, you don't have to worry too much about being reinfected from the toothbrush. The body has an immune system that forms antibodies when fighting diseases, so after recovering, you are usually not easily exposed to the same disease again.

In cases of bacterial sore throat (such as strep throat), research shows that the toothbrush used does not necessarily contain more bacteria that cause the disease. This means that changing the toothbrush is not always necessary.

The risk of transmission is actually greater for others. If you keep your toothbrush in one container with family members while you are sick, you should replace all toothbrushes. Germs from one toothbrush can spread to other toothbrushes and make others sick.

In addition, toothbrushes should be replaced after experiencing oral herpes (cold sore). The virus that causes herpes remains in the body and can cause re-infection. To prevent this, experts recommend throwing away toothbrushes, lip balms, cosmetics, or other items that have come into contact with herpes sores.

According to the American Dental Association (ADA), scientific data on toothbrush sterilization is still limited. However, there are small studies that show that soaking a toothbrush in a 3% hydrogen peroxide solution for about seven minutes can help reduce bacteria.

Another method that is considered quite effective is the use of special ultraviolet (UV) sterilization tools for toothbrushes, which are now widely sold online. However, this sterilization is optional, not mandatory.

How to Care for a Toothbrush to Stay Clean

To keep your toothbrush hygienic, here are some simple steps recommended by experts:

1. Don't share toothbrushes or toothpaste with others.

2. Rinse the toothbrush with running water after use to remove any toothpaste and dirt.

3. Let the toothbrush dry naturally in a standing position. Avoid closing or storing it in a closed container because the moist condition makes it easier for bacteria to grow.

4. Replace your toothbrush every three to four months, or sooner if the bristles are damaged or swollen.

Experts do not recommend sterilizing toothbrushes with a microwave or dishwasher because the heat can damage the toothbrush.
