Approximately one-tenth of all antimicrobials used globally are prescribed by dentists. They are most frequently used in urgent care cases rather than routine dentistry, and although considered appropriate for the treatment of certain infections and ailments, they are sometimes less appropriately prescribed for other conditions (e.g. dry socket). Whilst antimicrobials can be immensely useful, dentists have an important role to play in helping to tackle the threat of antimicrobial resistance. This collection gathers together the best evidence about the use, and the consequences of misuse, of these important drugs.
