What Should You Do Before Your Sedation Appointment?

Preparation for sedation dentistry begins well before your appointment day. Taking care of logistics and health considerations in advance ensures a smooth experience.

Complete Your Health History

Provide your dental office with a complete and accurate health history, including all medical conditions, past surgeries, current medications (prescriptions, over-the-counter drugs, and supplements), allergies, and any previous experiences with anesthesia or sedation. This information helps your dentist select the safest sedation approach for you.

Obtain Medical Clearance If Needed

Patients with certain conditions—heart disease, respiratory disorders, sleep apnea, or other significant health issues—may need clearance from their physician before sedation. Your dentist will let you know if this applies to you. Schedule any required consultations early to avoid delaying your dental treatment.

Arrange Transportation and Support

For oral and IV sedation, you cannot drive yourself home. Arrange for a responsible adult to bring you to your appointment, wait during your procedure, drive you home, and stay with you for several hours afterward. This person should be someone you trust to monitor you and contact the dental office if any concerns arise.

Plan Your Recovery Time

Clear your schedule for the remainder of the day following oral or IV sedation. You won’t be able to return to work, care for children without assistance, or handle important responsibilities. Many patients feel back to normal by the next morning, but some grogginess may persist.

Fill Prescriptions in Advance

If your dentist prescribes any medications—either sedation medication to take before your appointment or post-procedure medications—fill these prescriptions ahead of time. Having everything ready prevents last-minute complications.

What Should You Do the Day Before Your Appointment?

The day before your sedation appointment involves final preparations and beginning any required restrictions.

Confirm Your Appointment and Transportation

Call your dental office if you have any last-minute questions. Confirm the appointment time and verify any specific instructions. Touch base with your designated driver to confirm they’re still available.

Avoid Alcohol

Do not consume alcohol for at least 24 hours before your sedation appointment. Alcohol can interact with sedative medications and affect how your body responds to sedation.

Take Any Pre-Appointment Medication

For some oral sedation protocols, you may be instructed to take a pill the night before your appointment to help you sleep and reduce anxiety. Take this medication exactly as directed, at the specified time.

Prepare Your Recovery Space

Set up a comfortable area at home where you can rest after your appointment. Have pillows, blankets, water, and anything else you might need within easy reach. Prepare soft foods if you expect to be hungry later but may have difficulty eating due to numbness or tenderness.

Get a Good Night’s Sleep

Rest well the night before your procedure. Being well-rested helps your body respond appropriately to sedation and aids in recovery.

What Should You Do the Morning of Your Appointment?

The morning of your sedation appointment requires careful attention to fasting guidelines and other final preparations.

Follow Fasting Instructions Precisely

Fasting requirements vary by sedation type and are critical for your safety:

Fasting prevents a dangerous complication called aspiration, where stomach contents could enter the lungs if vomiting occurs during sedation. If you eat or drink when you shouldn’t, tell your dental team immediately—your appointment may need to be rescheduled for your safety.

Take Approved Medications

Your dentist will tell you which regular medications to take the morning of your appointment. Typically, essential medications like blood pressure medicine can be taken with a small sip of water. Never stop prescribed medications without specific guidance from your dentist or physician.

Dress Appropriately

Wear comfortable, loose-fitting clothing. Choose a shirt with short sleeves or sleeves that roll up easily above the elbow for IV placement if applicable. Avoid tight waistbands, complicated outfits, or anything that might be uncomfortable while you’re reclined for an extended period.

Leave Valuables at Home

Remove jewelry, watches, and other valuables before leaving home. Leave unnecessary items in the car or at home to minimize what you need to keep track of while sedated.

Skip Makeup and Remove Contact Lenses

Avoid wearing makeup, especially around the eyes, as monitoring equipment may be placed on your face. Remove contact lenses before your appointment and wear glasses instead, or bring a case to store them.

What Happens During Your Sedation Procedure?

Understanding what happens during your procedure helps reduce anxiety about the unknown. While your experience will depend on which sedation type you receive, here’s what to generally expect.

Arrival and Check-In

When you arrive, the dental team will verify your identity, confirm your health information, and ask about your fasting compliance. They’ll take your vital signs (blood pressure, heart rate, oxygen saturation) to establish baseline measurements.

Sedation Administration

For nitrous oxide, a nasal mask is placed and you begin breathing the gas mixture—effects start within minutes. For oral sedation, you may have already taken your medication at home or you’ll take it upon arrival and wait for it to take effect (30–60 minutes). For IV sedation, a small catheter is placed in your arm or hand, and medication is administered directly into your bloodstream with effects beginning almost immediately.

Continuous Monitoring

Throughout your procedure, the dental team continuously monitors your vital signs. Equipment tracks your heart rate, blood pressure, oxygen levels, and breathing. A team member is dedicated to monitoring your status while the dentist focuses on your dental treatment.

The Dental Treatment

Once you’re appropriately sedated, your dentist proceeds with the planned treatment. Local anesthesia is still used to numb the treatment area—sedation relaxes you but doesn’t eliminate the need for local numbing. Depending on your sedation level, you may be aware of activity around you (nitrous oxide), drowsy and drifting in and out (oral sedation), or have no awareness at all (IV sedation).

Completion and Initial Recovery

When your procedure is complete, the sedation is either discontinued (nitrous oxide is turned off) or allowed to wear off naturally (oral and IV sedation). You’ll remain in the dental chair or be moved to a recovery area where staff continue to monitor you until you meet discharge criteria.

What Should You Expect Immediately After Sedation?

Your immediate post-sedation experience varies based on the type of sedation you received.

After Nitrous Oxide

Effects clear within 5–10 minutes of removing the mask. You’ll breathe pure oxygen briefly to flush the nitrous from your system. Most patients feel completely normal and can drive themselves home and return to regular activities immediately.

After Oral Sedation

You’ll feel drowsy and may have difficulty walking steadily. The dental team will help you to the waiting area where your driver meets you. You may not remember leaving the office or the drive home. Effects typically last 4–6 hours, though some grogginess may persist longer.

After IV Sedation

You’ll spend time in a recovery area while the sedation wears off enough for safe discharge. You may feel confused or disoriented initially. Your companion will be brought back to stay with you. Walking will require assistance. Effects typically last 6–12 hours, with some patients feeling groggy into the next day.

How Should You Care for Yourself During the First 24 Hours?

The first 24 hours after oral or IV sedation require special precautions. Even if you feel fine, sedative effects can linger and impair judgment, coordination, and reaction time.

Activities to Avoid for 24 Hours

• Driving or operating machinery: Your reaction time and judgment remain impaired even if you feel alert
• Making important decisions: Don’t sign contracts, make major purchases, or have serious conversations
• Drinking alcohol: Alcohol compounds sedative effects and delays recovery
• Taking sedatives or sleep aids: Unless specifically prescribed by your dentist
• Caring for others without help: Don’t be solely responsible for children or dependents
• Strenuous exercise: Rest and allow your body to recover

Eating and Drinking After Sedation

Start with clear liquids and progress to soft foods as tolerated. Avoid hot foods and beverages until any numbness from local anesthesia wears off—you could burn yourself without realizing it. Nausea is possible after sedation; if you feel queasy, stick to bland foods and small amounts of liquid until it passes.

Rest and Recovery

Plan to rest for the remainder of the day. Sleep is normal and helpful for recovery. Have someone check on you periodically. Keep your head slightly elevated if you feel dizzy when lying flat.

Follow Post-Procedure Dental Care Instructions

In addition to sedation recovery, follow any instructions related to your dental treatment—care for extraction sites, avoid certain foods, take prescribed medications, and so forth. Your dental team will provide written instructions covering both sedation recovery and procedure-specific aftercare.
