- <p> Dental fillings may be contributing to the spread of
- antibiotic resistance
- </p>
- <p> Tooth fillings have been accused of everything from
- picking up radio transmissions to causing learning disabilities.
- Now comes another charge that could stick: fillings may be
- partly to blame for the growing problem of antibiotic-resistant
- bacteria.
- </p>
- <p> The real villain is the mercury that makes up about 50% of
- dental amalgam. In a study reported in the journal Antimicrobial
- Agents and Chemotherapy, monkeys with mercury fillings showed
- a jump in drug-resistant bacteria from 9% to 70%; when the
- fillings were removed, resistance dropped to 12%. It seems the
- genes that protect bacteria from mercury lie close to those that
- protect against antibiotics, so bugs that survive one tend to
- survive the other.
