You should not eat or drink anything—solid food, gum, mints, or even water—for at least 6 hours before your wisdom teeth removal surgery, especially if general anesthesia or sedation will be used. This fasting rule is important because eating beforehand increases the risk of complications like nausea, aspiration (food or liquid entering the lungs), and other anesthesia-related issues during the procedure.
Key Guidelines
- If you are receiving only local anesthesia, your fasting instructions may vary, but most oral surgeons still recommend having an empty stomach before surgery—always follow your specific surgeon's advice.
- Before fasting begins, it is safe to eat soft, easily digestible foods like scrambled eggs, yogurt, or soup the evening prior to your surgery.
- You may be allowed a very small sip of water to take prescribed medications, if instructed.
- Avoid heavy, fatty, or greasy foods at least 8 hours before your appointment, and stay hydrated with non-caffeinated beverages the day before, stopping all clear liquids two hours prior to surgery.
What Happens If You Eat?
- Eating or drinking during the restricted hours can increase risks under sedation, such as aspiration into the lungs, which can lead to severe complications and may even cause your procedure to be canceled or postponed for safety reasons.
Always check and follow the specific instructions your oral surgeon provides, as guidelines can vary depending on your health history and the anesthesia chosen.
