Typically, sedation is not necessary for a routine dental cleaning. A dental cleaning is a non-invasive procedure that involves the removal of plaque and tartar from the surface of the teeth, and most patients are able to tolerate the procedure with minimal discomfort.

However, if you have significant anxiety or fear related to dental procedures, your dentist may be able to provide some form of sedation to help you relax during a cleaning. This can include options such as nitrous oxide (also known as "laughing gas"), oral sedatives, or IV sedation, depending on the level of sedation required and the patient's overall health.

It's important to discuss any concerns or questions about sedation options with your dentist prior to the procedure to determine the best approach for your individual needs.
