I’ve used Bleach on My Teeth for years

So yeah as the title says I did this to myself for years. Ever since news of h5n1 potentially becoming the next human pandemic at any time I’ve done this. I know it’s really bad. I want to stop but idk how. I feel embarrassed that I have done it for so long. I don’t know how to stop being afraid of h5n1. Not to mention I stepped near where a dead American robin was at so now I’m just scared. I want at least a close alternative but there is little to no research on any mouthwash or toothpaste that would help kill h5n1. Please give advice I know I should see a professional but I don’t have the time or money at the moment to make an appointment
