Generally speaking, having a dental crown placed should not cause any pain during or after the procedure itself due to local anesthesia used before treatment; any discomfort experienced afterward should be minimal and can typically be managed with over-the-counter pain medications such as ibuprofen or acetaminophen if necessary. However, there may be some pressure felt during placement due to tightness caused by having your mouth open for long periods of time during treatment so you should advise your dentist if you experience any pain or discomfort at any time during your visit so they can address it accordingly.
