Who Benefits from Sedation Dentistry

Sedation is not reserved for severe dental phobia. Many patients with reasonable anxiety or practical concerns choose sedation simply because it makes treatment more comfortable and efficient.

Dental Anxiety

Patients who feel anxious or fearful about dental visits to any degree. Sedation removes the barrier to care and makes appointments feel manageable, even after years of avoidance.

Complex or Lengthy Procedures

Oral surgery, multiple extractions, implant placement, and full-mouth reconstruction. Sedation allows more treatment in fewer visits and makes long appointments comfortable.

Sensitive Gag Reflex

A hyperactive gag reflex can make routine procedures difficult. Even mild nitrous oxide can reduce gag sensitivity enough to allow comfortable completion.

Difficulty Getting Numb

Patients with dental anxiety or active infection sometimes require higher anesthetic doses. Sedation reduces anxiety-driven sensitivity and lowers the threshold for adequate numbness.

Special Needs

Patients with cognitive or physical disabilities, autism spectrum disorder, or movement disorders may benefit from deeper sedation or general anesthesia to receive safe, thorough care.

Personal Preference

Some patients simply prefer not to be fully aware during dental procedures. This is a valid reason to choose sedation, and we fully support that preference.

Sedation Options at SmileScience

We offer the full spectrum of sedation. Dr. Dawson will recommend the level that matches your procedure, health history, and preferences.

  1. Nitrous Oxide: Light Sedation

    Inhaled through a small nasal mask, nitrous oxide produces a calm, relaxed feeling within minutes. You remain fully conscious and able to respond. Effects wear off within a few minutes of removing the mask. You can drive yourself home. Best for mild anxiety and shorter procedures.

  2. Oral Conscious Sedation: Moderate

    A prescription-strength benzodiazepine taken by mouth before your appointment. You will feel drowsy and deeply relaxed, though still conscious. Most patients have little to no memory of the appointment. A driver is required to take you home. Best for moderate anxiety and procedures of any length.

  3. IV Sedation: Deep (Twilight)

    Medication delivered intravenously produces deep relaxation that can be adjusted in real time. You are deeply relaxed with minimal awareness and virtually no memory of the procedure. At SmileScience, IV sedation is administered by a board-certified anesthesiologist (not Dr. Dawson) who focuses exclusively on your sedation while Dr. Dawson treats you. A driver is required. Best for surgical cases, significant anxiety, and complex multi-procedure appointments.

  4. General Anesthesia: Full Unconsciousness

    You are completely unconscious and unaware throughout the procedure. General anesthesia is administered and managed entirely by a board-certified anesthesiologist in our office. Reserved for the most complex surgical cases, patients with severe phobia, and medically complex patients requiring dedicated anesthesiologist oversight. A driver and responsible adult at home for the day are required.

Board-Certified Anesthesiologist On Site

Many dental offices offer "IV sedation" administered by the treating dentist. At SmileScience, IV sedation and general anesthesia are managed by a board-certified anesthesiologist who comes to our office specifically for your appointment.

This means two specialists in the room: one focused entirely on your sedation and safety, and one focused entirely on your dental treatment. It is the same model used in hospital operating rooms, and it is a significant safety distinction.

  • Continuous vital sign monitoring: heart rate, blood pressure, O2 saturation, respiratory rate
  • Reversal medications and emergency equipment on-site
  • Thorough medical history review before sedation selection
  • Physician-level oversight for medically complex patients

What to Expect on a Sedation Day

  1. Step 1

    For oral, IV, or general anesthesia sedation, you will receive fasting instructions (typically nothing to eat or drink for 6 to 8 hours before your appointment). A driver must accompany you. Wear comfortable, loose-fitting clothing.

    Pre-Appointment Instructions

  2. Arrival and Pre-Sedation Check

    Step 2

    Vital signs are taken when you arrive. For IV sedation and general anesthesia, the anesthesiologist reviews your health history, places monitoring leads, and establishes IV access before any medication is given.

  3. Step 3

    Sedation is administered and the team waits until you are at the appropriate comfort level before beginning treatment. For IV sedation and GA, the anesthesiologist manages your sedation depth throughout while Dr. Dawson treats you.

  4. Treatment

    Step 4

    Your procedure is completed while you are comfortable and largely unaware. More treatment is often completed in a single sedation visit, reducing your total number of appointments.

  5. Step 5

    You are monitored in our recovery area until you are stable. Your driver takes you home. Plan to rest for the remainder of the day. Most patients resume light activities the following morning.

Sedation Dentistry FAQs

Yes, when performed by appropriately trained practitioners on medically suitable patients. Lighter sedation carries minimal risk for healthy adults. Deeper sedation, including IV sedation and general anesthesia, carries more risk, which is why SmileScience uses a board-certified anesthesiologist for these cases. A thorough health history review ensures the right sedation level is matched to your medical profile.

Not technically. IV sedation produces a state of deep relaxation and minimal awareness, often called "twilight sedation." Most patients can still respond to verbal cues if necessary but have no memory of the procedure. General anesthesia is the option that produces complete unconsciousness.

Nitrous oxide wears off within minutes after the mask is removed. Oral sedation can leave you drowsy for several hours; full mental clarity may not return until the following morning. IV sedation effects typically resolve within a few hours, though you should not drive or make important decisions for 24 hours. Plan for adult supervision at home if needed.

Coverage varies significantly by plan. Nitrous oxide is sometimes covered. IV sedation and general anesthesia are less commonly covered for routine procedures but may be covered when medically necessary, for example, for patients with documented anxiety disorders or special needs. Our team will help you verify your benefits before your appointment.

For nitrous oxide, no fasting is required. For oral sedation, light fasting is typically recommended. For IV sedation and general anesthesia, you must not eat or drink anything, including water, for 6 to 8 hours before your appointment. Specific instructions will be provided when you schedule.

It depends on the level. Nitrous oxide and oral conscious sedation are administered by Dr. Dawson, who holds OCS certification in Arizona. IV sedation and general anesthesia are administered by a board-certified anesthesiologist who comes specifically to our office for these cases. This two-provider model is the same standard used in hospital operating rooms.

Yes. Nitrous oxide and oral sedation can be used for routine cleanings if anxiety makes them difficult. Many patients who have avoided the dentist for years use sedation for their first few visits until they feel comfortable. There is no procedure too small to justify sedation if it helps you receive care.

Some medical conditions require adjustments to sedation protocol or limit which levels are safe. Obstructive sleep apnea, obesity, uncontrolled hypertension, certain respiratory conditions, and some medications can affect sedation planning. Your full medical history is reviewed before any sedation is recommended. In some cases, we may consult with your physician before proceeding.

Sedation fees vary by level and length. Nitrous oxide is typically a low per-visit add-on. Oral sedation is a moderate fee. IV sedation and general anesthesia carry a higher fee due to the anesthesiologist. Many patients find that completing more treatment per sedation visit actually reduces total appointments and total cost over time. We provide a clear fee estimate before scheduling any sedation appointment.

Yes. Patients with a history of painful or frightening dental experiences are excellent candidates for sedation. Because sedation produces amnesia for most patients, each sedation visit replaces a potential negative memory with essentially no memory. Over time, many patients become more comfortable with dental care generally and require less sedation as trust builds.

Who Is a Good Candidate for Sedation Dentistry?

Most patients with dental anxiety, a strong gag reflex, or complex treatment needs qualify for at least one level of sedation. Here is what we look for.

Severe Dental Anxiety

Patients who have avoided the dentist for years due to fear. Sedation provides a genuine reset.

Strong Gag Reflex

Sedation significantly reduces gag sensitivity, enabling procedures that are otherwise difficult to complete.

Multiple Procedures in One Visit

Sedation allows far more treatment time without fatigue, distress, or discomfort -- fewer appointments overall.

Physical or Cognitive Challenges

Conditions that make staying still difficult benefit greatly from deeper sedation -- where staying cooperative is not required.

History of Traumatic Dental Experiences

Sedation breaks the cycle of anxiety. Most patients form far more positive associations with dental care after a sedation visit.

Difficulty Getting Numb

Anxiety-driven heightened sensitivity is a real phenomenon. Sedation addresses the neurological component that makes local anesthetic less effective in anxious patients.

When Additional Planning is Needed

IV sedation requires additional planning for certain respiratory conditions, some medications (including benzodiazepines and MAOIs), pregnancy, obstructive sleep apnea, and uncontrolled cardiovascular conditions. Your full medical history is reviewed at every sedation appointment. This review is not a barrier to care -- it is how we match the right sedation level safely to your profile. The vast majority of patients qualify for at least one level.

What Does Sedation Cost?

Sedation fees vary by type and case length. Here is a general guide to what to expect, along with how we handle estimates.

Nitrous Oxide

$50 -- $100

per visit, light sedation

No fasting required. You drive yourself home.

Oral Conscious Sedation

$150 -- $300

moderate sedation

Driver required. Most patients remember little to nothing.

IV Sedation

The Value of Combining Sedation with Longer Appointments

Many patients find that combining sedation with a longer appointment -- completing multiple procedures in one visit -- reduces total treatment cost compared to multiple shorter visits. Fewer appointments also means less time off work and fewer co-pays or visit fees. We will discuss this approach with you at your consultation.

Sedation Dentistry Glossary

A colorless, odorless gas inhaled through a nasal mask that produces a calm, relaxed feeling within minutes. Consciousness is fully maintained. Effects resolve within minutes of removing the mask, and you can drive yourself home. Also called laughing gas.
A prescription benzodiazepine taken by mouth 30 to 60 minutes before an appointment. Produces deep relaxation while maintaining consciousness. Arizona requires a separate OCS permit for dentists administering it. A driver is required; most patients have little to no memory of the visit.
Medication delivered intravenously that produces a deep state of relaxation adjustable in real time. At SmileScience, IV sedation is administered exclusively by a board-certified anesthesiologist. Also called twilight sedation. A driver and responsible adult escort home are required.
Complete unconsciousness induced and maintained by a board-certified anesthesiologist. Reserved for the most complex surgical cases, patients with severe phobia, or medically complex patients who require physician-level monitoring throughout their treatment.
American Society of Anesthesiologists physical status score (ASA I-VI) used to evaluate patient health before administering sedation. ASA I is a healthy patient; ASA VI is a brain-dead organ donor. Most dental sedation candidates are ASA I or II.
Nothing by mouth prior to sedation. Required for oral sedation, IV sedation, and general anesthesia to reduce aspiration risk during sedation. Specific fasting windows (typically 6 to 8 hours) are provided when you schedule.
