Millions of Americans avoid dental care not because they don’t need it, but because they can’t face it. Dental anxiety keeps patients from scheduling appointments, delaying care until small problems become expensive ones. If that describes you, sedation dentistry may be the reason you finally get the care you’ve been putting off — without the dread that has been stopping you.
At Seattle Smiles Company, Dr. Ajay Kashi offers the full spectrum of dental sedation options — from mild nitrous oxide to general anesthesia administered by a certified registered nurse anesthetist (CRNA) — all at our downtown Seattle office. Whether your barrier is anxiety, a sensitive gag reflex, or the need for extensive work in a single visit, we tailor a sedation plan around your specific needs, your medical history, and your comfort goals. Free consultations are available for all new patients.
What Is Sedation Dentistry?
Sedation dentistry uses medication to help patients relax and remain comfortable during dental procedures. It is an effective solution for patients who experience dental phobia, anxiety, or sensitivity, as well as those undergoing extensive or invasive treatments. The level of sedation ranges from mild relaxation to complete unconsciousness, depending on your procedure and your needs.
Many patients confuse sedation with pain management — they serve different purposes. Local anesthesia numbs the treatment area so you don’t feel pain. Sedation manages anxiety, suppresses the gag reflex, and keeps you calm from start to finish. Most appointments combine both approaches. According to the Washington State Department of Health, dentists in Washington must meet specific training and permitting requirements to administer moderate and deep sedation — a standard our team meets and maintains for every sedation level we offer.
The Four Sedation Options We Offer
Seattle Smiles Company offers four distinct levels of dental sedation. Here is how they compare across the dimensions that matter most to patients.
Nitrous Oxide (Laughing Gas)
Nitrous oxide is the mildest form of dental sedation. Administered through a small mask over your nose, you inhale a gentle blend of nitrous gas and oxygen. Most patients feel deeply relaxed within minutes while remaining fully conscious and responsive. Effects wear off completely within five minutes of removing the mask, so you can drive yourself home afterward.
Oral Sedation
Oral sedation involves taking a prescribed pill — typically from the benzodiazepine family — about an hour before your appointment. You will feel deeply relaxed and drowsy, though still able to respond to questions. Patients often have little memory of the procedure afterward. Because effects last several hours, you will need a responsible adult to drive you home. This option suits patients with moderate to severe dental anxiety who want minimal awareness during treatment.
IV Sedation
IV sedation delivers medication directly into your bloodstream through a small needle, allowing precise, real-time control over sedation depth. You enter a deeply relaxed twilight state with little to no memory of the procedure — most patients feel the appointment lasted only minutes, even when treatment took hours. A responsible adult must drive you home and remain with you for several hours after treatment.
General Anesthesia
General anesthesia is the deepest level of dental sedation and the only option that produces complete unconsciousness. You will not feel, hear, or remember anything during your procedure. A certified registered nurse anesthetist (CRNA) monitors your vital signs continuously throughout treatment. This option is ideal for extensive surgical procedures, patients with severe dental phobia, or those with special needs requiring complete immobility.
Who Benefits Most from Sedation Dentistry?
Dental anxiety affects a significant portion of the population and is one of the leading reasons patients defer necessary care for years. Estimates suggest dental fear and anxiety affect 30 to 80 percent of people in the United States. Sedation dentistry works especially well for patients who:
- Experience mild to severe dental phobia or anxiety
- Have a sensitive gag reflex that makes procedures uncomfortable
- Require complex or extensive dental work across multiple treatment areas
- Have had past negative dental experiences or dental trauma
- Have difficulty sitting still for extended appointments
- Need multiple procedures completed in a single visit
- Have special needs requiring additional comfort accommodations
Sedation also allows Dr. Kashi to work more efficiently — completing in one visit what might otherwise require multiple shortened appointments — reducing cumulative anxiety and saving you time overall.
What to Expect at Your Sedation Appointment
Your appointment follows a clear, monitored sequence designed to keep you safe and comfortable from arrival through recovery.
Is Sedation Dentistry Safe?
Yes — when administered by a trained team following current clinical protocols. At Seattle Smiles Company, every sedation appointment includes a thorough pre-treatment assessment to match the sedation type to your medical profile. For general anesthesia cases, a CRNA is present and monitoring throughout treatment. Our team holds all required Washington State certifications and maintains current emergency response protocols for every level of sedation we offer.
Do You Qualify for Dental Sedation?
Most healthy adults are candidates for at least one form of dental sedation. During your consultation, we conduct a thorough medical history review to identify any factors that may affect which sedative agents are appropriate. Please bring a complete list of your current medications, including over-the-counter supplements and vitamins.
Nitrous oxide is generally safe for patients of all ages. IV sedation and general anesthesia require a more detailed health assessment. When specific concerns arise, our team collaborates with your primary care provider to confirm your safety before proceeding with treatment.
Frequently Asked Questions About Sedation Dentistry
Here are answers to the questions patients ask most before their sedation appointment.
Will I be asleep during the procedure?
Not necessarily — it depends on which sedation option you and Dr. Kashi select. Nitrous oxide and oral sedation keep you conscious but deeply relaxed. IV sedation places you in a twilight state with little to no awareness. Only general anesthesia produces complete unconsciousness. During your consultation we will explain exactly what to expect from each option and help you choose the right fit.
How long does dental sedation last?
Duration varies by type. Nitrous oxide wears off within five minutes of the mask being removed — you can drive home immediately. Oral sedation effects typically last four to six hours. IV sedation clears within a few hours after your appointment. General anesthesia requires the longest recovery, generally several hours under supervision at our office before you are cleared to leave with your driver.
Will I remember anything from my procedure?
With nitrous oxide, most patients retain full memory of the appointment. With oral sedation or IV sedation, most patients remember very little, if anything. General anesthesia produces no memory of the treatment at all. This amnesic effect is one of the features patients with severe dental anxiety find most reassuring about deeper sedation options.
Does dental insurance cover sedation dentistry?
Coverage varies by plan and the clinical reason for sedation. Some insurance plans cover sedation when it is medically necessary — for example, for patients with severe anxiety, special needs, or for complex surgical procedures. We recommend contacting your provider directly to confirm your benefits. Our team also offers flexible financing through Cherry, Alphaeon Credit, Proceed Finance, Scratch Pay, and CareCredit, plus an in-house membership plan for patients without insurance.
Can sedation dentistry be used for children?
Nitrous oxide is commonly used for pediatric patients and is considered safe for children. IV sedation and general anesthesia may also be appropriate for children with significant dental anxiety or special needs, subject to a medical evaluation. Our team will assess your child’s situation and recommend the appropriate option during the consultation.
