A new study has warned that dentures, despite its clean look, could be teeming with killer bugs like MRSA.
Researchers have advised that putting infected false teeth in a microwave oven for three minutes makes them safe. Dentures are known to get covered with thin layers of bacteria called biofilms, which can lurk until they are breathed into the lungs.Nearly 20 million people in the U.S. wear full or partial dentures often infected with MRSA or drug-resistant staphylococcus aureus bacteria. The team of scientists from Brazil who carried out the research also suggested soaking them in a germicidal mouthwash solution of two per cent chlorhexidine gluconate for 10 minutes, the Daily Mail reported.
Either method is sufficient to disinfect dentures coated with the toughest MRSA biofilms for up to a week, according to the study led by Karen Tereza Altieri, a dentist at the Araraquara Dental School at the Universidade Estadual Paulista in Sao Paulo.
"To our knowledge, we are the first investigators to report the effectiveness of this method in killing MRSA," she said.
Leaving dentures in a glass overnight may not be enough to keep them clean, scientists say. Microwaving them for three minutes would be better, a study found. MRSA, full name Meticillin Resistant Staphylococcus Aureus, is a bacteria resistant to some antibiotics and usually found on false teeth, scientists said.
