Do I Need to Replace The Toothbrush After Strep Throat?

When recovering from strep throat, it’s important to consider your oral hygiene routine, especially your toothbrush. Many people wonder whether they need to replace their toothbrush after an illness like strep throat to avoid reinfection. Let’s dive into why replacing your toothbrush post-illness can be beneficial and how to maintain good hygiene during your recovery.

What is Strep Throat? 

Strep throat is a bacterial infection caused by Streptococcus bacteria. It can cause a sore throat, fever, and swollen lymph nodes, and it’s highly contagious. Once you’re diagnosed and start treatment, you’ll likely want to minimize any chance of reintroducing the bacteria back into your system—and this is where your toothbrush plays a role.

Should You Replace Your Toothbrush After Strep Throat?

Yes, it’s generally recommended to replace your toothbrush after recovering from strep throat. Here’s why:

• Bacteria on the Toothbrush: Strep bacteria can linger on your toothbrush, and continuing to use it may increase the risk of reinfection.
• Reduced Immunity: After recovering from strep throat, your immune system may still be weakened, making you more susceptible to another round of illness if you’re exposed to lingering bacteria.
• General Oral Hygiene: Even without strep throat, it’s good practice to change your toothbrush every 3-4 months or after any illness to maintain optimal oral hygiene.

How to Clean or Disinfect a Toothbrush After Strep Throat?

If you’re unable to replace your toothbrush immediately, here are some steps to disinfect it:

• Rinse with Hydrogen Peroxide: Soaking your toothbrush in hydrogen peroxide can kill bacteria and reduce the risk of reinfection.
• Boil Your Toothbrush: Boiling the toothbrush in water for a few minutes can help kill any remaining germs.
• Use an Antibacterial Mouthwash: Rinse the bristles with antibacterial mouthwash to clean the toothbrush.

However, while these methods can disinfect your toothbrush, replacing it altogether is the safest option.

When Should You Replace Your Toothbrush?

In addition to after illness, here are other times when you should consider changing your toothbrush:

• Every 3-4 Months: Over time, toothbrush bristles wear out and become less effective at cleaning your teeth.
• After Recovering from Illness: Whether it’s the flu, a cold, or strep throat, replacing your toothbrush after being sick is a good hygiene practice.
• If the Bristles are Frayed: Frayed bristles won’t clean your teeth as effectively, and they can harbor bacteria.

How to Maintain Toothbrush Hygiene Going Forward?

To keep your toothbrush clean and reduce the risk of reinfection or contamination:

• Store it Upright: Allow your toothbrush to air dry in an upright position. Avoid storing it in closed containers, which can promote bacterial growth.
• Avoid Sharing Toothbrushes: Sharing toothbrushes can spread bacteria and infections.
• Rinse Thoroughly After Use: Rinse your toothbrush under tap water after each use to remove any toothpaste and debris.
• Use a Toothbrush Cover: If you’re traveling or storing your toothbrush in a shared bathroom, consider using a cover to protect it from bacteria.
