Lidocaine‐based teething gels have been widely available in Australia for decades in both commercial preparations and those compounded by pharmacies. However, many case reports have highlighted potential risks and toxicity associated with lidocaine‐based teething gels when used in infants and young children, including seizures, respiratory arrest and death. The Australian and New Zealand Society of Paediatric Dentistry and the American Academy of Paediatrics do not recommend topical agents for teething, and the US Food and Drug Administration does not recommend topical lidocaine for this purpose due to concerns of toxicity. Literature supporting the efficacy of lidocaine for teething is scant and difficult to interpret due to the flawed design of the trials conducted and varied formulations used. This opinion article aims to summarise the available literature showing the limited effectiveness and associated risks of topical lidocaine gels for use in teething. In light of these findings, the authors recommend that regulatory bodies such as the Australian Therapeutic Goods Administration review the efficacy and safety of this type of medicine and consider removing the indication for teething or limiting the age of use to older children.
