The KNMT has published 10 practical guidelines for dentists treating patients who observe Ramadan, the Islamic fasting period that ran from 18 February to 18 or 19 March 2026. During Ramadan, observant Muslims fast from before sunrise to sunset, which affects treatment planning, medication schedules, and oral hygiene routines. Most dental treatments can proceed during Ramadan provided no fluids or water are swallowed as a result of the procedure. Dentists should allow more frequent rinsing and spitting. Flavoured products, including mint, should be avoided during cleaning. Medication timing requires adjustment: prescribing twice daily instead of three times daily avoids the daytime fasting window, and consultation with a pharmacist is advised when necessary. Pain medication may be taken if pain is severe enough to interrupt the fast. Some patients view local anaesthesia as medication and may decline it or request to postpone treatment. At the start of Ramadan, patients may present with headaches, nausea, or general malaise. Increased sugar consumption during non-fasting hours raises caries risk, so dietary advice is appropriate. Fasting can also cause halitosis, which may be reduced by tongue scraping and maintaining standard oral hygiene.
