Preparing for wisdom teeth removal starts a few days before surgery and covers everything from what you eat that morning to what you stock in your kitchen for recovery. Most of the prep is straightforward, but missing a step (like eating too close to your appointment) can delay or cancel your procedure. Here’s what to handle ahead of time so the day itself goes smoothly.
Follow Fasting Rules Carefully
If you’re getting any form of sedation or general anesthesia, you’ll need an empty stomach. The standard guideline is no solid foods or dairy for at least 8 hours before your scheduled arrival time. Clear liquids like water, black coffee, or apple juice are fine and actually encouraged up until 2 hours before you arrive.
This matters because sedation relaxes the muscles that normally keep food out of your lungs. If your stomach isn’t empty, there’s a risk of aspiration during the procedure. If you accidentally eat within the fasting window, tell your surgeon’s office rather than hoping it won’t matter. They may need to push your appointment back. For procedures done under only local anesthesia (just numbing shots, no sedation), fasting usually isn’t required, but confirm with your surgeon.
Review Your Medications Early
Give your oral surgeon a full list of everything you take, including over-the-counter painkillers, supplements, and vitamins. Do this at your consultation, not the morning of surgery.
Blood thinners are the biggest concern because they increase bleeding during and after extraction. Interestingly, the American Dental Association notes that for most patients on common blood thinners or antiplatelet medications like aspirin, the medication regimen does not need to change before dental procedures. This applies to newer blood thinners as well. The key is that your surgeon and your prescribing doctor make that call together. Don’t stop any prescribed medication on your own.
For patients considered higher risk for bleeding, the timing of a daily dose might be shifted so the procedure falls as late as possible after the last dose, or therapy might be paused for 24 to 48 hours. Again, this decision involves your physician.
Mention Heart Conditions and Joint Replacements
Certain heart conditions require a dose of antibiotics before the procedure to prevent a rare but serious infection of the heart lining. According to American Heart Association guidelines, this applies to people with prosthetic heart valves (including transcatheter-implanted ones), a history of infective endocarditis, certain unrepaired congenital heart defects, or heart transplants with valve problems. If any of these apply to you, make sure your surgeon knows well before surgery day.
If you have an artificial joint (hip, knee, shoulder), you can relax on this one. The ADA reviewed the evidence and concluded there’s no proven link between dental procedures and joint replacement infections, so routine antibiotics aren’t recommended for that reason alone.
Stop Smoking and Vaping Ahead of Time
Smoking significantly raises your risk of dry socket, one of the most painful complications after wisdom tooth extraction. Dry socket happens when the blood clot that forms in the extraction site gets dislodged or dissolves too early, exposing the bone and nerves underneath. Inhaling on a cigarette or vape creates suction that can pull that clot loose, and the chemicals in tobacco also impair blood flow to the healing tissue.
The American Association of Oral and Maxillofacial Surgeons recommends discussing your smoking, vaping, and marijuana habits at your preoperative visit so your surgeon can give you a personalized timeline for stopping. The longer you can abstain before surgery, the better your healing will go. This applies equally to cannabis. If you use marijuana, tell your surgeon, because it can also interact with anesthesia.
Stock Your Kitchen Before Surgery
You won’t want to go grocery shopping after your procedure, so buy soft foods a day or two in advance. The goal is nutrient-dense options that require no chewing. The American Dental Association recommends these staples:
- Pureed or cream soups (butternut squash, lentil, chicken broth-based)
- Soft scrambled eggs
- Oatmeal or cream of wheat
- Yogurt (low sugar is easier on sensitive gums)
- Mashed potatoes
- Cottage cheese
- Smoothies or protein shakes
For extra protein, keep protein powder on hand to mix into shakes or stir into broth. Mashed avocado is a good source of healthy fat. Soft fruits like peaches, kiwi, and strawberries are high in vitamin C, which supports tissue repair. For dinners, think mild white fish with light seasoning, steamed soft vegetables like squash or peas, or polenta.
One thing to watch: keep soups and drinks warm, not hot. Piping hot liquids can irritate the surgical site and complicate healing. Your surgeon will tell you when you can return to crunchy or hard foods like chips and raw vegetables.
Prepare Your Recovery Setup
Pick up a few supplies so you’re not scrambling afterward. You’ll want gauze pads (your surgeon’s office will likely send you home with some, but extras help), an ice pack or bag of frozen peas for swelling, and salt for rinses. The standard recipe is 1 teaspoon of salt dissolved in 8 ounces of warm water. You’ll typically start these rinses the day after surgery and repeat up to four times a day, plus after meals.
Set up a comfortable spot where you can rest with your head slightly elevated. Lying flat can increase swelling and throbbing. Have entertainment ready because you’ll be sedentary for at least a day or two. Pillowcases you don’t mind staining are a practical touch, since some oozing is normal the first night.
Plan the Day-Of Logistics
If you’re receiving sedation of any kind, you cannot drive yourself home. Arrange for someone to pick you up, and ideally have them stay with you for the first few hours while the anesthesia wears off. Most offices won’t begin the procedure unless they know you have a ride confirmed.
Wear a short-sleeved shirt or something with loose sleeves, since a blood pressure cuff and pulse monitor will go on your arm. Skip contact lenses and wear glasses instead. Leave jewelry and valuables at home. Wear comfortable, flat shoes since you may be unsteady on your feet afterward.
If your surgeon prescribed anything to take the morning of the procedure (sometimes an anti-anxiety medication or antibiotic), take it with a small sip of water as directed. Otherwise, stick to the fasting guidelines. Brush your teeth normally that morning.
What to Skip the Night Before
Avoid alcohol for at least 24 hours before surgery. Alcohol thins the blood slightly, can interact unpredictably with anesthesia, and dehydrates you at a time when you want to be well-hydrated going in. Drink plenty of water the day and evening before (remembering to stop clear liquids 2 hours before your arrival time).
Try to get a full night’s sleep. Anxiety about the procedure is completely normal, but being well-rested helps your body handle anesthesia and begin healing faster. If you tend to be anxious about medical procedures, mention it at your consultation. Many oral surgeons can prescribe a mild sedative to take the night before or morning of your appointment.
