What you do before oral surgery is almost as important as the surgery itself. Proper preparation identifies health risks, optimizes your body for surgery and healing, reduces complications, and ensures your surgery goes smoothly. Let's talk about what your surgical team needs to know about you and what you need to do to prepare.

Your Medical History: Everything Your Surgeon Needs to Know

Your surgeon needs complete information about:

Heart conditions: Previous heart attacks, heart failure, arrhythmias, high blood pressure. Any of these affects anesthesia choice and surgical approach.
Breathing problems: Asthma, COPD, sleep apnea. These affect oxygen management during surgery.
Bleeding disorders: Any history of excessive bleeding, clotting problems, blood thinners (warfarin, aspirin, Xarelto, etc.). This directly affects bleeding control during and after surgery.
Diabetes (especially your most recent blood sugar level).

High blood sugar impairs healing and increases infection risk.

Medications: Everything you take, including over-the-counter drugs, supplements, and herbal products. Some interact with anesthesia or affect bleeding.
Prior anesthesia problems: Any bad reactions to anesthesia previously. This helps your anesthesiologist choose safer agents.
Recent surgeries: What was done and when. Helps identify healing issues or ongoing complications.

Don't minimize or forget things—your surgeon needs complete information to keep you safe. Write down your medications and conditions before your appointment so you don't forget anything.

Medications: What to Take, What to Skip

Herbal supplements: Products like ginkgo, ginger, and garlic thin blood. Stop them 1-2 weeks before surgery. Yes, these are "natural"—so is hemlock, which is poisonous. Natural doesn't mean safe for surgery. Blood thinning effects add up and can cause excessive bleeding during surgery. Blood thinners: This is complex and depends on what you're taking and why. Generally:

Warfarin (Coumadin): Minor procedures (single tooth extraction, implant): Keep taking it. Your surgeon will check your INR level beforehand. Major surgery (multiple extractions): Stop 3-5 days before surgery. Talk to your cardiologist—they'll coordinate with your surgeon.

The reason you're taking warfarin (probably heart condition or stroke prevention) is serious, so you can't just stop without medical guidance.

Apixaban, dabigatran, edoxaban, rivaroxaban (newer blood thinners): Minor procedures: Usually keep taking. Major procedures: Ask your surgeon and cardiologist. These newer agents work differently than warfarin and often don't need stopping.
Aspirin alone: Usually keep taking for minor procedures. It provides less bleeding risk than warfarin.
Aspirin + other antiplatelet drugs (like after a stent): Don't stop without talking to your cardiologist. Stopping too soon risks stent clots, which is dangerous.

Never stop blood thinners on your own. Call your doctor. Other medications: Take your normal medications the morning of surgery unless told otherwise. Critical medications (high blood pressure, heart, thyroid) usually need to be taken even before surgery. Your surgeon will give you specific instructions about what to take and what to skip. Diabetes medications: If you take insulin, take 50% of your usual morning dose the day of surgery (because you're fasting and won't be eating). If you take pills only, ask your surgeon—different pills have different rules. Bring blood sugar level information and your glucose meter.

Pre-Surgery Bloodwork and Tests

Your surgeon might order:

Blood work: INR if you take warfarin (checks how thin your blood is), blood glucose if diabetic (checks sugar control). These directly affect surgical safety.
X-rays or CBCT scan: To see exactly where teeth are, where nerves are, any complications. This helps your surgeon plan exactly what they'll encounter.
EKG: Only if you have significant heart issues or are very high-risk. This checks your heart rhythm before surgery.

These tests catch problems before surgery, when they can be managed safely.

Anxiety Management

If you're nervous (totally normal!), tell your surgeon. You might be able to take an anti-anxiety medication before surgery, which helps tremendously. Anxiety increases heart rate and blood pressure, which increases bleeding risk. Taking something to calm down is actually safety optimization, not coddling.

Some options: oral anti-anxiety medication 30-60 minutes before surgery, or IV sedation where you're relaxed throughout. Your surgeon can discuss options.

Fasting and Preparations

If you're having sedation or general anesthesia:

No food 6+ hours before surgery (solid food should be completely gone)
No liquids 2 hours before surgery (small sips of water up to that point)
This prevents your stomach contents from going into your lungs if you vomit (aspiration). It's a critical safety measure.

Transportation: Arrange someone to drive you home. Sedation impairs judgment for 12-24 hours, so you can't drive yourself. This isn't optional—it's your safety and everyone else's on the road. Day before: Get good sleep, eat well, stay hydrated. Your body needs good baseline condition going into surgery.

Your surgeon will discuss:

Risks: Bleeding, infection, swelling, temporary numbness, nerve injury, dry socket (after extraction), implant failure (if applicable). Every surgery has risks. Your surgeon is obligated to tell you what can go wrong so you can make an informed choice.
Benefits: Removing the tooth/problem, fixing your bite, creating space.

The reasons you're having surgery.

Alternatives: What could happen if you don't have surgery. Sometimes waiting and watching is an option. Sometimes the problem gets worse without treatment.
Your specific situation: If your case has unique risks (nerve is very close, tooth is difficult, etc.). Individual risk factors matter.

Read the consent form carefully. Ask questions. Make sure you understand everything before you sign. This isn't a bureaucratic formality—it's your right to understand what's happening to your body.

The Surgical Team's Checklist

Before you even get on the surgical chair, your team verifies:

You're the right patient (matches wristband)
It's the right procedure (matches your chart)
Your medical history is accurate (anything new today?)
Your vital signs are normal (baseline blood pressure, heart rate, oxygen)
Imaging is available and reviewed (they can see what they're operating on)
Instruments and medications are ready (everything they need is available)
Emergency medications are available (if something goes wrong, they can respond immediately)

This systematic checklist prevents serious mistakes. It might feel repetitive, but that redundancy saves lives.

Final Preparations

Day of surgery:

Take any medications you're supposed to take (unless told not to fast)
Wear comfortable, loose clothing (you might be swollen post-surgery)
Bring a list of your medications and allergies (for the record)
Don't wear jewelry, contacts, or makeup (jewelry can catch on things, makeup prevents seeing if you're pale from blood loss, contacts can be uncomfortable if you're sedated)
Leave valuables at home (reduce theft risk from hospital/office)

After arriving:

Be honest with staff about anything new (new illness, bleeding, etc.)
Ask any last-minute questions
Tell them if you're especially anxious (they can adjust sedation plans)

The Goal

Proper preparation identifies risks, lets your surgeon plan perfectly, prevents surprises, and ensures you heal well. Don't skip these steps or hide information—they exist to keep you safe. Your surgeon has probably done your procedure hundreds of times, but each person is different. Complete information lets them customize the approach for you specifically.

The surgeon who knows your complete medical history and has seen your imaging can perform surgery more safely and faster than one who's surprised by something unexpected.

Always consult your dentist to determine the best approach for your individual situation.

Conclusion

Your dentist can help you understand the best approach for your specific needs. The surgeon who knows your complete medical history and has seen your imaging can perform surgery more safely and faster than one who's surprised by something unexpected.
