Preparing for wisdom teeth removal mostly comes down to practical logistics: arranging your ride home, stocking up on soft foods, following fasting rules, and knowing what to wear. Most of the prep happens in the 24 to 48 hours before your appointment, though a few things, like sorting out insurance and talking to your surgeon about medications, should happen as early as possible.
Fasting Rules Based on Your Sedation Type
How long you need to stop eating and drinking depends on the type of sedation your surgeon plans to use. If you’re getting IV sedation or general anesthesia, most offices require you to have nothing to eat or drink for at least 6 to 8 hours before surgery. Clear liquids (water, apple juice, anything you can see through) are typically allowed up to 4 hours before the procedure. If you’re only getting nitrous oxide (laughing gas), the window is shorter: no food or drink, including water, for at least 3 hours beforehand.
You can still brush your teeth the morning of surgery. Just be careful not to swallow any toothpaste or mouthwash. A clean mouth actually helps reduce bacteria at the surgical site, so don’t skip your normal oral hygiene routine.
Medications and Supplements to Discuss Early
If you take blood thinners, this conversation needs to happen well before surgery day. Blood thinners include prescription medications like warfarin, as well as newer options like rivaroxaban and apixaban. But over-the-counter pain relievers like ibuprofen (Advil, Motrin) and naproxen (Aleve) also increase bleeding risk. So do many herbal supplements, including fish oil, ginkgo, and garlic capsules.
The important thing: do not stop any medication on your own. Suddenly stopping a blood thinner can trigger serious complications like blood clots. Your oral surgeon and prescribing doctor will coordinate whether to pause, adjust, or continue your medication. This discussion can take a few days to sort out, so bring it up at your consultation, not the night before.
If you have a heart condition, artificial heart valve, history of endocarditis, or certain congenital heart defects, your surgeon may prescribe a preventive antibiotic to take before the procedure. Patients with diabetes should ask about timing their insulin or oral medications around the fasting window. Your surgeon may also request medical clearance from your cardiologist or primary care doctor, which can take a week or more to process.
Arrange Your Ride and Post-Surgery Help
If you’re receiving any level of sedation beyond local anesthesia, you cannot drive yourself home. Your escort needs to be a responsible adult who can stay in the waiting area during the procedure and drive you back. Many offices require this person to walk you in, not just wait in the parking lot.
Plan to have someone with you for at least a few hours after you get home. Sedation affects coordination, judgment, and reaction time, and these effects can linger well into the afternoon or evening. If you live alone, ask a friend or family member to stay with you or check in regularly for the rest of the day.
What to Wear on Surgery Day
Wear a short-sleeved shirt. Your surgical team needs access to your arm for IV placement and blood pressure monitoring. You can layer a sweatshirt or jacket over it for the drive, but you’ll need to remove it before the procedure starts. Stick to loose, comfortable clothing overall.
Wear closed-toe shoes with a secure fit, not sandals or flip-flops. You may be unsteady on your feet afterward, and slip-on footwear increases your fall risk. Skip makeup, especially around your eyes, and remove contact lenses before the appointment. Glasses are fine.
Stock Up on Recovery Supplies
You will not want to run errands after surgery, so get everything you need the day before. Here’s what to have at home:
- Soft foods: yogurt, applesauce, pudding, mashed potatoes, smooth soups (not hot), smoothie ingredients. You’ll eat these for several days, so buy more than you think you need.
- Cold packs: a reusable ice pack or even a bag of frozen peas works well. You’ll apply it to the outside of your cheek for 15 to 20 minutes at a time to control swelling.
- Gauze pads: your surgeon will likely send you home with some, but having extra on hand is smart. You’ll bite down on folded gauze to control bleeding for the first few hours.
- Extra pillows: keeping your head elevated while resting helps reduce swelling. Stack two or three pillows so you’re propped up rather than lying flat.
Avoid buying anything that requires a straw. The sucking motion can dislodge the blood clot forming in the extraction site, leading to a painful complication called dry socket.
Smoking, Alcohol, and Cannabis
Stop smoking as far in advance of surgery as you can. Smoking restricts blood flow and slows healing, and the inhaling motion carries the same dry socket risk as using a straw. The American Association of Oral and Maxillofacial Surgeons recommends discussing your smoking, alcohol, and cannabis habits with your surgeon during your preoperative visit so they can give personalized guidance on when to stop and when it’s safe to resume.
Alcohol should be avoided in the 24 hours before surgery at minimum. It can interact with anesthesia and increase bleeding. Cannabis is worth mentioning specifically because it can affect how your body responds to sedation, potentially requiring higher doses or causing unexpected reactions.
Sort Out Insurance and Costs Ahead of Time
Wisdom teeth removal can be covered under dental insurance, medical insurance, or both, depending on your plan and the reason for extraction. This is worth investigating well before surgery day. Call your insurance company’s customer service line directly to verify what’s covered for the specific procedure codes your surgeon’s office provides.
For costly procedures, you can request a predetermination of benefits. This is a voluntary process where the insurance company estimates what they’ll pay based on your current coverage. It’s not a guarantee of payment (your eligibility or remaining benefits could change by the surgery date), but it gives you a realistic picture of your out-of-pocket costs. Submit this request as close to your planned surgery date as possible to get the most accurate estimate. Many offices will handle this step for you if you ask.
Managing Anxiety the Night Before
Nervousness before oral surgery is completely normal. A few things genuinely help. Deep breathing, meditation, or progressive muscle relaxation (tensing and releasing muscle groups one at a time) can lower your stress response and make it easier to fall asleep. Prioritize sleep: being well-rested makes a measurable difference in how you handle both the procedure and the initial recovery.
If your anxiety is severe enough that relaxation techniques aren’t cutting it, mention this to your surgeon’s office. Some practices prescribe a mild sedative to take the night before or the morning of surgery. This is separate from the sedation you’ll receive during the procedure itself, and it needs to be arranged in advance.
