Anesthetic and sedation options are available to prevent you from feeling pain and discomfort during your dental procedure.
Sedation dentistry keeps you comfortable during dental procedures. It’s beneficial for people with dental anxiety or for those who are undergoing lengthy treatment. Options include nitrous oxide, oral conscious sedation and intravenous (IV) sedation. Dentists must have special certification to provide some forms of sedation dentistry.
What is sedation dentistry?
Sedation dentistry helps you feel calm, relaxed and at ease during dental procedures. It’s a moderate level of sedation, so you’re still technically awake but feeling very carefree. It’s sometimes called conscious sedation dentistry or “twilight sleep” because it creates a state of short-term amnesia (forgetfulness) where you experience insensitivity to pain without the loss of consciousness.
Who needs sedation dentistry?
People of all ages can benefit from sedation dentistry, including children. Dentists often recommend this option for those with:
- Dental anxiety.
- A fear of visiting the dentist.
- An overly sensitive gag reflex.
- A fear of needles (aichmophobia).
- Extreme teeth sensitivity.
- Feelings of claustrophobia while in the dental chair.
- Decreased sensitivity to local anesthesia.
- Difficulty controlling movements.
- Special needs (including physical, cognitive or behavioral).
What types of sedation are used in dentistry?
There are varying levels of sedation dentistry based on your unique needs. Factors include your level of anxiety, the length of your procedure, your health history and personal preferences. The most common types of sedation dentistry include nitrous oxide, oral conscious sedation and intravenous (IV) sedation.
Nitrous oxide is commonly known as “laughing gas.” You inhale nitrous oxide through a mask or nosepiece, and calming effects begin within three to five minutes. Your dentist controls the amount of sedation you receive and adjusts dosages accordingly throughout your procedure. Once your treatment is over, your dentist gives you pure oxygen to flush the nitrous oxide out of your system. Because the laughing gas leaves your system so quickly, you’ll be able to drive yourself home after the procedure.
Oral conscious sedation
With oral conscious sedation, your dentist gives you sedative medication (usually in pill form) about an hour before your procedure begins. Most dentists use triazolam (Halcion®), which is in the diazepam (Valium®) family. But your dentist might use other medications, too, including zaleplon and lorazepam. Dentists often used liquid sedation in pediatric dentistry, such as midazolam oral syrup.
Oral sedation makes you quite groggy, and you may even fall asleep. But you’ll still be able to communicate with your dentist if necessary, and you’ll awaken with a gentle nudge. Because oral sedation temporarily affects your memory and motor skills, you’ll need a friend or family member to drive you home after your procedure.
Intravenous (IV) sedation
IV sedation dentistry is the deepest form of conscious sedation available in a dental office setting. Your healthcare provider delivers sedative medications directly to your bloodstream through an IV line. During your procedure, your dentist monitors your heart rate, blood pressure and oxygen levels. They can adjust your dosage at any point and can use reversal medications if necessary. Most people who receive IV sedation dentistry fall asleep and have little to no memory of their treatment when they wake up. This option is best for people with severe dental anxiety or those who are undergoing lengthy procedures.
What happens before sedation dentistry?
You’ll talk with your dentist about sedation options during your initial consultation. They’ll discuss your health history and ask about any medications or supplements you’re taking. Once they’ve gathered all the necessary information, they’ll make sedation recommendations based on your specific needs.
In most cases, you shouldn’t eat or drink anything for at least six hours before your dental appointment. Unless otherwise noted by your dentist, you should take all routine medications without interruption.
Be sure to tell your dentist if you’re taking any blood thinners, though, such as warfarin. They may ask you to skip these medications for a few days leading up to your procedure.
What happens during sedation dentistry?
Your dentist gives you sedative medications before beginning your procedure. You’ll still receive local anesthetic to numb your teeth and gums, but your dentist usually does this once you’re already feeling comfortable from the sedatives.
What happens after sedation dentistry?
Unless you choose nitrous oxide as your sedation option, you’ll need a trusted friend or family member to drive you home after your appointment. You should go straight home and rest while the sedative medication wears off.
Note: Never take a taxi or rideshare home after sedation dentistry. You’ll need a trusted and familiar person to help you. Before leaving you alone, your driver should make sure you’re resting comfortably in bed or on your couch.
RISKS / BENEFITS
What are the advantages of sedation dentistry?
Sedation dentistry eases anxieties and phobias, helping you remain calm and comfortable during dental procedures. Because your dentist can often work faster when you’re under sedation, it can result in fewer appointments. Finally, many people have so much dental anxiety that they avoid going to the dentist altogether. Sedation dentistry helps you feel more comfortable so you can receive the care you need and deserve.
What are the risks or complications of sedation dentistry?
Sedation dentistry is typically safe when administered by a licensed healthcare provider. However, there’s a small risk of complications. Possible short-term risks include:
- Lingering drowsiness.
- Can be difficult to predict the effect of oral sedation medications.
- Dry mouth (xerostomia).
- Nausea and vomiting.
- Bruising from the IV.
It can also be difficult to predict the effect of oral sedation medications. Rarely, people may have an allergic reaction. There are drugs available that can counteract these issues.
Child sedation dentistry side effects
Sedation dentistry is safe for kids. But as a parent, it can still be scary when your child takes unfamiliar medications. Child sedation dentistry side effects are usually short-lived, but they can include:
- Nausea and vomiting.
Sometimes, your child can be slow to wake after sedation. If this happens, your dentist will monitor your child until they’re ready to go home. These side effects are normal and should go away on their own in a day or two. If you have specific questions or concerns, call your dentist.
Can I have sedation dentistry if I’m pregnant?
Generally, sedation dentistry isn’t recommended for people who are pregnant because some sedative medications can affect fetal development. Nitrous oxide may be given during the second trimester in some cases. But overall, most dentists wait until after pregnancy to administer sedation dentistry.
RECOVERY AND OUTLOOK
What is the recovery time?
Recovery times vary. It depends on what type of sedation you choose and how your body responds to the medications. In general, people who have nitrous oxide recover within 15 to 30 minutes and can drive themselves home following their appointment. Those who choose oral conscious sedation or IV sedation typically need about 24 hours for full recovery.
When can I go back to work or school?
If you’ve had nitrous oxide, you can return to normal activities once you leave the dental office. However, if you’ve had oral or intravenous sedatives, you’ll need to wait at least one full day before returning to work or school. Some people may need longer. Your dentist can tell you what to expect in your situation.
When can I drive?
If you’ve had oral sedation or IV sedation, you’ll need to wait a full 24 hours before driving again. If you’ve only had nitrous oxide, you can drive once you’ve been released from the dental office.
When can I eat?
You can eat and drink immediately after your appointment; though, most people prefer to wait until the numbness from the local anesthesia wears off. It’s best to start with something light, like clear liquids, and progress from there to a smoothie or milkshake. If you’re feeling up to it, you can eat something more substantial after a couple of hours.
Your dentist will provide you with a list of postoperative guidelines. These instructions will tell you which types of food you should avoid and which ones are safe to eat. For most dental procedures, you’ll be able to eat normally again within one week. It might take longer if you’ve had work done on both sides of your mouth.
WHEN TO CALL THE DOCTOR
When should I see my healthcare provider?
If you’ve recently had sedation dentistry, it can take at least 24 hours for the effects to wear off. If you develop worrisome symptoms, such as nausea or vomiting, a fever above 101 degrees Fahrenheit (38.33 degrees Celsius) or pain that doesn’t improve with medication, call your dentist for further instructions.
