About Fasting and Teeth

Fasting and Teeth is an independent guide for adults who follow, or are thinking about, intermittent fasting and want to look after their teeth and gums while doing it. It is not a clinic and does not replace a dentist.

The guides cover everyday questions: dry mouth, how often your teeth meet sugar and acid, coffee and other drinks, brushing around an eating window, and breath. Each one ends with a practical next step or questions to bring to your dental team.

The aim is simple: to help readers make sense of everyday oral health topics in plain language, so they can make calm, informed choices and know when it is time to book an appointment.
