A recent study has revealed some of the bacteria found on orthodontic retainers, worn after orthodontic treatment is completed, can be associated with the hospital superbug MRSA, a condition which can lead to blood poisoning.

The research, carried out by the UCL Eastman Dental Institute in London (1), also found a further two thirds of retainers examined contained a type of yeast connected with fungal infections, with both types of organism found potentially harmful to the population.
