<p>The lack of dental travel health care has been deplored for some time. Travel medicine’s remit is to prepare people for travel. People travel with their mouth firmly in their body, yet the mouth’s wellbeing does not rate a mention. This article represents the first exploration of a range of topics relevant to an until now neglected, yet potentially highly important, area of health care. A range of dental mishaps can occur while away from home, from simple toothache to accidents, serious emergencies, or restoration failures. Other problems originate in unwise behaviour, including holiday-inspired body modifications.</p><p>Unless there is pain, teeth are typically not thought about much. However, examining the practical side of dental hygiene during travels, several overlooked and perhaps surprising topics emerge that – through the travel lens – take on a different and important role: the oral microbiome, toothbrush hygiene, the toilet plume, and traveller diarrhoea. Based on this discussion, recommendations are made for clinical practice, education, and further research.</p><p>The historical chasm between dentistry and medicine, despite long-standing calls for change, does not seem to go away and impairs holistic high quality travel health care. Travel medicine can bypass this unproductive division. It has the unique opportunity to be the first medical specialty cooperating closely with dentists to bridge this gap by providing quality travel health care to travellers with all their body parts attached.</p>
