Before dental procedures, fasting may be advised. Fasting means abstaining from food and drink for a specific period before the procedure. Whether or not fasting is necessary prior to a dental appointment depends on the type of procedure being performed and the patient's medical history. For routine checkups or cleanings, fasting is typically not required.
However, for more complex procedures such as surgeries or sedation, fasting may be necessary to ensure patient safety. Fasting helps reduce the risk of complications during and after the procedure. It also helps to prevent nausea and vomiting, which can occur if food or drink is present in the stomach during the procedure.
