How Do You Protect Your Toothbrush If Someone In Your House Has COVID?

Ensuring the safety of your toothbrush amid a COVID-19 scenario is paramount for maintaining oral hygiene.

According to recommendations from the University of Southern Utah Extension, we advise avoiding the sharing of toothbrushes and maintaining distance between them to prevent potential cross-contamination risks.

This simple yet effective measure significantly reduces the likelihood of virus transmission within your household.

Furthermore, disinfecting the handle of the toothbrush is an additional precautionary step recommended by dental experts at SNOW.

Also, consider the toothbrush length to ensure it can be stored properly without touching other toothbrushes or surfaces, minimizing contamination risks.

Utilizing antibacterial mouthwash or hydrogen peroxide for this purpose can help minimize the risk of spreading the virus and maintain a hygienic oral environment amidst the pandemic.

Can Your Toothbrush Make Others Sick?

Yes, the toothbrush can indeed pose a risk of making others sick if proper hygiene protocols are neglected.

Sharing toothbrushes is particularly concerning as it can lead to the transfer of harmful viruses and bacteria, including COVID-19.

We strongly advise you to avoid sharing toothbrushes to mitigate the risk of illness transmission. Each person in the household should have their own toothbrush to maintain hygiene standards and prevent the spread of germs.

Regularly disinfecting toothbrushes and implementing effective oral hygiene practices are crucial steps in minimizing the likelihood of illness transmission.

SNOW emphasizes the importance of maintaining good oral hygiene habits, including proper toothbrush care and regular replacement, to ensure optimal dental health and reduce the risk of spreading illnesses to others.


Understanding the relationship between your toothbrush and COVID-19 is crucial for maintaining optimal oral health and preventing the spread of the virus.

By following the recommendations outlined in this guide, including avoiding sharing toothbrushes, regularly disinfecting your toothbrush, and replacing it after illness, you can effectively minimize the risk of reinfection and protect yourself and your loved ones from illness.
