For many people, dental visits can cause anxiety or fear. If you feel nervous about an upcoming procedure, sedation dentistry can help you relax while receiving the care you need. One of the most common and effective options is intravenous (IV) sedation. This method uses medication delivered through a vein to make you feel calm and less aware of what is happening during your treatment.
In this guide, we’ll explain everything you need to know about IV sedation — including how to prepare, what happens during the procedure, and the steps you should follow afterward for a safe and smooth recovery.
What Is Intravenous Sedation?
Intravenous sedation is a form of conscious sedation used in dentistry to help patients stay relaxed and comfortable. The sedative medication is given through a small needle inserted into a vein, usually in your arm or the back of your hand.
The goal of IV sedation is not to put you completely to sleep, but to create a deeply relaxed state where you remain awake and able to communicate with your dental team. Many patients remember very little about the procedure afterward, which can be a relief for those with dental anxiety.
Why Choose IV Sedation Dentistry?
There are several reasons why patients choose IV sedation over other types of sedation:
-
Reduces anxiety – Helps patients who are nervous or fearful about dental work.
-
Minimizes discomfort – Keeps you comfortable during longer or more complex procedures.
-
Provides quick effect – The medication works quickly once it enters your bloodstream.
-
Allows for adjustable dosage – Your dentist can control the level of sedation during the procedure.
-
Encourages regular care – Patients who avoid the dentist due to fear may feel more comfortable getting needed treatment.
If you struggle with dental anxiety, a strong gag reflex, or difficulty sitting still, IV sedation can make your visit more manageable.
Before Your Appointment: How to Prepare for IV Sedation
Good preparation is the key to a safe and successful IV sedation experience. Here’s what you should do before the day of your procedure:
1. Stay Hydrated
Drink plenty of water in the hours leading up to your appointment. Good hydration makes it easier for your dental team to find a vein for the IV and helps your body process the medication.
2. Eat a Light Meal
Have a light meal one to two hours before your appointment. Avoid heavy, greasy, or spicy foods, as these may upset your stomach. Your dentist will let you know if you need to adjust this based on your specific treatment.
3. Continue Regular Medications (Unless Told Otherwise)
If you take daily prescription medication, continue taking it unless your dentist or doctor advises otherwise. Bring a list of all your medications to the appointment.
4. Wear Loose, Comfortable Clothing
Loose sleeves make it easier for your dental team to access your arm. Comfort is also important since you’ll be in the chair for a while.
5. Remove Nail Polish
Clear nails allow your dental team to monitor your oxygen levels during sedation. Nail polish can interfere with pulse oximeter readings.
6. Avoid Alcohol and Drugs
Do not drink alcohol or use recreational drugs — including cannabis — for at least 48 hours before and after your appointment. These substances can interact dangerously with sedation medication.
7. Do Not Smoke
Smoking can delay healing and increase the risk of complications. Avoid it before and after your procedure.
8. Pregnancy and Breastfeeding Considerations
If you are pregnant, IV sedation is not recommended. If you are breastfeeding, you will need to pause for 12 hours after the procedure.
9. Arrange for an Escort
You must bring a responsible adult (over 18, able-bodied) to accompany you. They will check in with you, wait during your procedure, and help you get home safely. You cannot go alone, and you should not bring children to your appointment.
What to Expect During the Procedure
Knowing what will happen can help you feel more at ease. Here’s what typically occurs during IV sedation dentistry:
1. Check-In and Preparation
When you arrive, your dental team will review your medical history, confirm your escort’s details, and explain the procedure again. They may check your blood pressure, pulse, and oxygen levels.
2. Starting the Sedation
The dentist or sedation specialist will insert a small needle into a vein in your arm or hand. The sedative medication will begin flowing, and you’ll start to feel calm and relaxed within minutes.
3. Staying Awake but Relaxed
You will not be unconscious — you’ll still be able to respond to questions and follow simple instructions. However, your sense of time and memory of the procedure will likely be limited.
4. Continuous Monitoring
Your vital signs, such as heart rate and oxygen levels, will be monitored closely throughout the procedure to ensure your safety.
5. Completion and Recovery Room
Once your dental treatment is complete, you’ll be moved to a recovery room. You’ll rest there until you’re able to walk unaided.
After Your Appointment: Recovery and Safety Guidelines
The effects of IV sedation can last 12 hours or longer. It’s important to follow recovery instructions to avoid accidents or complications.
1. Getting Home Safely
It’s best to travel by car or taxi with your escort. Public transportation is not recommended, as you may still feel groggy or unsteady.
2. Rest for the Remainder of the Day
Go home and relax. Avoid strenuous activities and make sure an adult stays with you during this time.
3. Avoid Caring for Others
Since your thinking and judgment may be impaired, don’t take on responsibilities like watching children or caring for pets.
4. Eat and Drink When Ready
Start with water or soft, cool foods. Avoid hot or chewy items until you feel fully recovered.
5. Activities to Avoid for 12 Hours
Until the sedation fully wears off, do not:
-
Drive or ride any vehicles
-
Operate machinery or appliances
-
Return to work
-
Make important decisions
-
Sign legal documents
-
Handle financial transactions
-
Use social media
These restrictions help prevent mistakes or accidents while your mental clarity is affected.
Potential Side Effects of IV Sedation
While IV sedation is considered safe when performed by trained professionals, you may experience mild side effects such as:
-
Drowsiness
-
Lightheadedness
-
Dry mouth
-
Temporary memory loss of the procedure
-
Slight bruising where the needle was inserted
These effects typically fade within 24 hours.
The Role of Your Escort
Your escort plays a vital part in ensuring your safety after IV sedation. They should:
-
Accompany you to and from the dental office
-
Stay with you for the rest of the day
-
Help you with basic needs like preparing food or getting comfortable
-
Monitor you for any unusual symptoms
Sharing the pre- and post-care instructions with your escort ahead of time ensures they’re prepared.
