What Is IV Sedation Dentistry?

Intravenous conscious sedation is used in dental surgery to achieve a high level of relaxation and comfort by administering sedatives right into the patient’s bloodstream. IV sedation allows you to serenely endure a bunch of invasive dental treatments such as implant placement, wisdom tooth extraction, and bone grafting. This method is indispensable when local anesthesia isn’t enough but general anesthesia is not required.

How Does IV Sedation Work?

Intravenous sedation is performed by an experienced dentist or anesthesiologist, who leads you to a state of deep relaxation by administering sedative drugs through your vein. The qualified professional monitors your vital signs during the whole procedure for utmost safety. The state of conscious sedation enables you to follow the doctor’s instructions, but you aren’t likely to remember the events after the effect of sedation elapses.

The role of the intravenous line

A peripheral intravenous line is a compact plastic catheter placed through the skin into a vein to give you sedative medications during conscious sedation. The process looks as follows:

1. A doctor applies a numbing medicine and finds a vein.
2. They secure an elastic band over the vein.
3. The dentist uses a needle to position a thin plastic tube into a vein.
4. When they extract the needle, the tube remains in place.
5. The doctor may protect the intravenous line with a plastic cover.

It typically takes a few minutes to be accurately positioned.

Types of sedative medications used

Common intravenous sedative drugs used for modern dental procedures include:

• Midazolam: decreases the excitability in neurons and eases the symptoms of anxiety;
• Dexmedetomidine: drives a patient to a condition that highly resembles normal physiological sleep, while decreasing the heart rate and blood pressure;
• Propofol: an effective agent with rapid recovery;
• Ketamine: produces dissociative sedation and causes mild cardiovascular stimulation, not recommended for patients with hypertension.

A dentist chooses an intravenous sedative type based on your medical history and current health concerns. 

How long the effects last

The treatment time depends on the applied type of sedative medications, loading dose, and whether it is a single drug or a combination. 

Intravenous Sedative	Effect Longevity
Midazolam	60-120 min
Propofol	3-10 min
Ketamine	5-10 min
Dexmedetomidine	60-120 min

What Does IV Sedation Feel Like?

The sedation drugs put you into a drowsy, semi-awake condition, but you won’t be entirely asleep. You will breathe on your own and react to the doctor’s guidelines. Afterward, you either won’t completely remember the procedure or have only a few hazy recollections. This enables a dentist to perform more treatments in a single visit if required, even if you suffer from dental anxiety. 

If you worry “Do you feel pain with IV sedation?”, we have good news. A pain-free experience is ensured by a combination of sedative medications and local anesthesia applied to the treated area.

Who Is a Good Candidate for IV Sedation?

While intravenous sedation isn’t recommended for people with particular medical conditions such as respiratory or heart issues, pregnant or breastfeeding women, and patients with experience in substance abuse, it handles many concerns.

Anxiety, fear of needles, or complex procedures

Intravenous sedation can help a range of patients comfortably undergo essential dental treatments:

• Dental Anxiety. IV sedation dentistry helps patients experiencing dental anxiety feel more at ease during the treatment. 
• Fear of Needles. If you have a distinct phobia, for example, a fear of needles, IV anesthesia can help you endure dental appointments.
• Complex Procedures. Some large-scale dental procedures such as a smile makeover, wisdom tooth removal, or dental implant placement may need much time to complete, raising the need for IV sedation. 

Conscious sedation ensures your comfort and enables a dental professional to perform the necessary treatment in the meantime. 

Medical history considerations

Your eligibility for IV sedation dentistry depends on your medical history. A dentist provides a comprehensive medical assessment prior to undertaking sedation dentistry for your safety. The doctor examines former and current health conditions, allergies, and medications to ensure you have no past experiences that can interfere with sedation. A comprehensive evaluation of your health status diminishes potential risks associated with receiving IV sedation.

What to Expect Before, During, and After the Procedure

We’ve divided the entire procedure into three parts for your convenience. Let’s see what you can expect from each stage.

Before: Consultation and preparation (fasting, medication, health check)

At the initial dental consultation, a doctor meticulously evaluates your medical history to ensure this type of sedation fits your specific needs. They inform you about the advantages and risks associated with IV sedation and provide all-encompassing instructions about fasting and medication. 

The average guidelines prescribe you to avoid eating or drinking for nearly 6–8 hours preceding the surgery. You should stick to expert instructions to prevent adverse reactions and ensure a consistent recovery.

During: How sedation is administered and monitored

A dentist places an intravenous line in your arm to provide you with sedative medications. You might wonder, “How long does sedation take to kick in?” The onset time varies, starting from 9 seconds for propofol and ending with 10 minutes for dexmedetomidine. While you are in a state of relaxation, the doctor incessantly monitors your vitals (including heart rate, oxygen saturation, and blood pressure) and adjusts the sedation level if necessary.

After: Recovery, side effects, and post-care instructions

Upon the procedure completion, you come out of the sedative state, feeling a bit drowsy. Since the medications wear off in a 24-hour timeframe, you need a helping hand to drive you home. Except for driving, avoid drinking alcohol, undertaking strenuous activities, and making significant choices till the 24 hours elapse. Minor post-sedation fatigue is considered normal and eventually reduces. Afterward, you can resume routine life, but always prioritize your dentist’s post-treatment instruction. 

Benefits and Risks of IV Sedation Dentistry

Let’s examine a bunch of benefits provided by IV sedation dentistry.

Why patients choose IV sedation
