This question often arises in the minds of health-conscious individuals who prioritize their well-being, particularly after battling a cold, flu, or other infectious ailments.

Should one err on the side of caution and invest in a new toothbrush after recovery, or could thorough sanitization suffice? What do dental professionals recommend on this matter?
