If you don’t replace your toothbrush or dull razor blades regularly, watch this video, which shows a doctor explaining how this impacts your health.
Dr Saurabh Sethi, a gastroenterologist, took to Instagram on May 7 to share a list of '3 toxic bathroom items to get rid of right away'.

Dr Sethi also warned: be cautious with anti-microbial mouthwash, as it can harm beneficial bacteria in the mouth and affect gut health. According to him, by being mindful of the following 'toxic items', you can maintain good oral hygiene and skin care practices.
Old toothbrushes
Dr Sethi said, “According to recent studies, 75 percent people use their toothbrushes longer than the recommended 3 months. After 3 months, toothbrushes lose up to 30 percent of their cleaning power, and bacteria can start building up on the bristles. So, if it has been 3-4 months, it is time to toss it.”
Dull razor blades
“Dull razor blades cause 10 times more skin irritation. To avoid skin damage and infections, replace them after 5 to 7 uses,” he added.
Antimicrobial mouthwash
Dr Sethi concluded, “Studies show that antimicrobial mouthwash can harm beneficial bacteria in the mouth, which can affect the balance of the gut microbiome.”
