We all know the mouth houses a lot of germs. That also goes for when you’re sick as well. Generally one should only use a toothbrush for about 90 days. Then toss it. When you catch a cold or flu, this little stick helps maintain the cooties in your mouth. By all means, as soon as your cold or flu starts to clear up, toss that bad boy in the trash and get a new toothbrush.
Your immune system will thank you!
