Dental anxiety is far more common than most people realize. Surveys consistently find that roughly 30 to 40 percent of adults experience significant fear or apprehension around dental and oral surgical procedures. For some, that anxiety leads to postponed or avoided care, which often turns manageable problems into more complex ones. Sedation dentistry exists specifically to address this barrier, making it possible to get the care you need comfortably and safely.
At Legacy Oral Surgery and Implants, Dr. Nancy Herbst and our team work with anxious patients every day. Oral and maxillofacial surgeons complete four to six years of advanced hospital-based surgical training after dental school, which includes comprehensive education in administering and monitoring all forms of anesthesia. That depth of training means we can offer every level of sedation in-office, tailored to your specific needs and procedure.
Why Dental Anxiety Is So Common
Fear of oral surgery often has identifiable roots. Common triggers include a prior negative experience, fear of needles or injections, concern about feeling pain during the procedure, or discomfort with the loss of control that comes from being reclined while someone works in your mouth. For others, it is simply the unfamiliarity of sounds, sensations, or instruments in a clinical setting.
Understanding the source of your anxiety is the first step. The next is knowing that every level of discomfort, from mild unease to severe avoidance, has a sedation option that can help. You do not need to white-knuckle your way through a procedure because you are nervous about it.
Your Sedation Options
There are three primary forms of sedation available in our office, along with local anesthesia as a baseline for all procedures. The right option depends on your level of anxiety, the complexity of the procedure, and your overall health profile.
Minimal Sedation: Nitrous Oxide (Laughing Gas)
Nitrous oxide is inhaled through a small mask placed over your nose. Within three to five minutes, you will feel calm, relaxed, and at ease while remaining fully conscious and able to respond to instructions. Dr. Herbst controls the concentration throughout the procedure and adjusts it as needed. When the procedure ends, pure oxygen flushes the nitrous oxide from your system within 10 to 15 minutes. This is the only form of sedation after which most patients can drive themselves home.
Nitrous oxide works well for patients with mild to moderate anxiety, shorter procedures, or those who prefer to stay alert throughout.
Moderate Sedation: Oral Conscious Sedation
Oral sedation involves taking a prescription anti-anxiety medication, typically from the benzodiazepine family, approximately one hour before your appointment. You will feel drowsy and deeply relaxed, and while you remain technically awake and able to respond, you will likely have little to no memory of the procedure afterward. This amnesic effect is often a significant relief for highly anxious patients.
Because the effects linger, you will need a responsible adult to drive you to and from the appointment and to stay with you for several hours during recovery. Fasting for several hours before the procedure is usually required. Our team will provide specific instructions based on the medication prescribed.
Deep Sedation: IV Sedation (Twilight Anesthesia)
Intravenous sedation delivers medication directly into the bloodstream through an IV line, allowing for rapid onset and precise, moment-to-moment control of sedation depth. Most patients have little or no memory of the procedure at all. IV sedation is not general anesthesia, which renders a patient fully unconscious, but it is the deepest level of conscious sedation available in an outpatient oral surgery setting.
IV sedation is ideal for patients with moderate to severe dental anxiety, longer or more complex procedures, or those who have found lighter sedation options insufficient in the past. It is also commonly used for wisdom tooth extractions involving multiple impacted teeth and for dental implant placements where patients want maximum comfort. You will need a driver and a responsible adult with you for the rest of the day following the procedure.
Matching Sedation to Your Procedure
The right level of sedation depends on both your anxiety and the nature of the procedure itself. A single, straightforward extraction may be very comfortable with local anesthesia and nitrous oxide. A procedure involving multiple impacted wisdom teeth, or placement of multiple dental implants, naturally pairs better with IV sedation for the most comfortable experience.
During your consultation, we will discuss what your specific procedure involves and walk through the sedation options that are appropriate for your situation. We will also review your medical history and any current medications, as certain conditions or drugs can influence which sedation methods are safe for you.

Preparing for a Sedated Procedure
Preparation requirements vary by sedation type. For nitrous oxide, no fasting is typically required, though eating a light meal at least two hours beforehand is recommended. For oral sedation and IV sedation, you will generally need to avoid food and drink for six to eight hours before the appointment. Arrive with a responsible adult who can drive you home and stay with you during initial recovery.
Let us know about all medications you are currently taking, including over-the-counter drugs, supplements, and herbal remedies, as some can interact with sedatives or affect how they work. If you have questions about whether a specific medication or health condition affects your candidacy, our team will work through those details with you before the appointment.
Frequently Asked Questions About Dental Sedation
Will I feel pain during a sedated oral surgery procedure?
No. Regardless of the sedation level chosen, local anesthesia is also administered to completely numb the treatment area. This means you have a double layer of protection: sedation to manage anxiety and awareness, and local anesthesia to prevent any sensation of pain. Most patients are pleasantly surprised by how comfortable the experience is.
Can I drive myself home after dental sedation?
After nitrous oxide only, most patients can drive themselves home once the effects wear off, typically within 15 minutes of removing the mask. After oral sedation or IV sedation, you must have a responsible adult drive you home and remain with you for several hours during recovery. The sedative effects persist well beyond the end of the procedure, making driving unsafe.
Is IV sedation the same as general anesthesia?
No. IV sedation, sometimes called twilight anesthesia, produces deep sedation and amnesia but keeps you in a conscious state where you can still respond to verbal instructions if needed. General anesthesia renders a patient fully unconscious and requires advanced airway management not typically performed in an outpatient office setting. IV sedation is very effective for oral surgery and carries a favorable safety profile when administered by a trained oral and maxillofacial surgeon.
What qualifications do oral surgeons have to administer sedation?
Oral and maxillofacial surgeons complete four to six years of hospital-based surgical residency training after dental school, which includes extensive hands-on education in administering and monitoring all forms of anesthesia. This makes them uniquely qualified to provide sedation in an office setting. Dr. Nancy Herbst and our team follow all state and national safety protocols for in-office anesthesia administration.
What if I have a health condition that might affect sedation?
Certain health conditions and medications can influence which sedation options are appropriate for you. During your consultation, we conduct a thorough review of your medical history and current medications. If a particular condition requires coordination with your primary care physician or specialist, we will work through that process with you before scheduling the procedure. Your safety and comfort are the priorities, and we will not proceed with any sedation approach until we are fully confident it is appropriate for you.
You should not have to live with oral pain or avoid necessary care because of anxiety. Whether you prefer the light relief of nitrous oxide or the deep comfort of IV sedation, we are trained and equipped to help you through your procedure safely.
