What is sedation dentistry?
Sedation dentistry uses medicine to help you feel calm and relaxed during treatment, on top of the local anesthetic that numbs the tooth. It treats anxiety, not pain: the numbing injection still does that job.
Sedation comes in levels. With minimal or moderate ("conscious") sedation, you stay awake enough to breathe on your own and respond to the dentist, but you feel drowsy and less aware of time. Many people remember little of the appointment. General anesthesia, where you are fully asleep, is a different service normally provided in a hospital setting with an anesthesia team.
Which types of sedation are used in dentistry?
Health authorities describe several options. Which ones suit you, and which ones a given clinic offers, is decided at consultation.
| Type | How it's given | How you feel | Recovery |
|---|---|---|---|
| Inhaled nitrous oxide ("laughing gas") | Mask over the nose | Relaxed, awake | Wears off quickly after the mask is removed |
| Oral anti-anxiety medicine | Tablet taken before the visit | Calmer, may be drowsy | Several hours; you need someone to take you home |
| Intravenous (IV) conscious sedation | Small cannula in the arm or hand | Deeply relaxed, may drift into light sleep but still responsive | Drowsy for the rest of the day; escort required |
| General anesthesia | Anesthesia team, usually in hospital | Fully asleep | Longer; pre- and post-operative checks |

Who is sedation dentistry for?
Sedation may help if you:
- Feel strong fear or panic about dental visits, or have avoided the dentist for years
- Have a strong gag reflex
- Need a longer procedure, such as wisdom tooth removal or dental implant surgery
- Find it hard to sit still for long periods
- Want to complete several treatments in fewer, longer visits during a short trip
It is not suitable for everyone. Some medical conditions, medicines, pregnancy, and certain breathing or sleep problems may rule it out or need extra precautions. Being honest about your health history is important for your safety.
What happens on a sedation appointment day?
- Health check. At an earlier consultation, the dentist reviews your medical history, medicines, allergies and previous reactions to anesthesia.
- Preparation instructions. You'll get written instructions, including any eating and drinking limits before the visit. Follow them exactly.
- Arrive with a companion. For oral or IV sedation, plan for an adult to come with you and take you back to your hotel.
- Monitoring. During sedation, your breathing, oxygen level and pulse should be monitored; ask how this is done.
- Treatment under local anesthesia while you are sedated.
- Recovery in the clinic until you are steady enough to leave with your companion.
- Rest for the day. Don't drive, drink alcohol, sign important documents, or make big decisions until the next day.
Is dental sedation safe?
For carefully selected patients, sedation performed by trained staff with proper monitoring is widely used in dentistry. It still carries risks, such as over-sedation, breathing changes, nausea and, rarely, allergic reactions, which is why screening and monitoring matter. The American Dental Association updated its guidelines on sedation and general anesthesia in April 2026, placing more emphasis on fasting guidance, supplemental oxygen and emergency preparedness. Ask any clinic you're considering how they monitor sedated patients and what their emergency plan is. Those are reasonable questions, and we're glad to answer them.
Is there a way to feel calmer without sedation?
Yes, and many nervous patients manage well with a few simple steps. Agree on a stop signal, such as raising your left hand, so you know you can pause at any time. Bring headphones and music. Ask the dentist to explain each step before doing it. Book a morning slot so you have less time to worry. Read more in our guide to dental anxiety for foreign patients.
Can I have sedation on a short trip to Seoul?
Often, yes, but it takes planning. Share your medical history before you arrive so the dentist can judge whether sedation is appropriate. Leave the rest of the sedation day free, and don't schedule a flight the same day. If you're traveling alone, tell us early so we can discuss options for getting back to your accommodation safely. Our treatment planning page and international patients hub explain how we schedule visits around your travel dates.
What should I ask before choosing sedation?
Good questions to bring to any consultation include:
- Which type of sedation do you suggest for my treatment, and why?
- Who gives the sedation, and who watches me while the dentist works?
- What will I be able to eat and drink beforehand, and which of my medicines should I still take?
- How long will I stay in the clinic afterward?
- What happens if I feel unwell later that evening, and how do I reach you?
How much does sedation cost?
Sedation is not listed on Lucid Dental's published non-covered fee table, because it depends on the method and the length of treatment. Ask for the fee in writing before your appointment. Sedation for anxiety is generally not covered by Korean national health insurance; confirm at consultation if you are enrolled.

Frequently asked questions
Will I be unconscious with conscious sedation?
No. You stay able to breathe on your own and respond to simple requests, though you may feel very drowsy and remember little. Being fully unconscious is general anesthesia, which is a different service.
Can I have sedation if I'm traveling alone in Seoul?
For oral or IV sedation, you should have an adult accompany you home and stay nearby for the rest of the day. If you're traveling solo, tell us early so we can talk through options, which may include lighter sedation or none.
Do I still get a numbing injection with sedation?
Yes. Sedation calms you, but the local anesthetic numbs the area being treated. Many sedated patients say they barely notice the injection.
How long does it take to recover from dental sedation?
Inhaled nitrous oxide wears off within minutes. Oral and IV sedation can leave you drowsy for several hours, so plan to rest for the remainder of the day.
Should I tell the dentist about medicines or supplements I take?
Yes, always. Some medicines, supplements and health conditions affect how sedation works or whether it is safe. Bring a written list in English, including doses.
