Dental procedures can be nerve-wracking, and most people aren’t keen on having pointy tools inside their mouths. So, how do dentists manage anxiety and discomfort during procedures?

Dentists will often use some kind of sedation to prevent pain and discomfort. In some cases, patients will have little to no memory of the procedure.

In this article, we’ll cover what sedation dentistry is, its cost, and its safety.

What is Sedation Dentistry?

Sedation dentistry involves using pharmacological agents to help people relax during dental procedures. It reduces anxiety, fear, stress, and discomfort associated with dental visits and procedures.

It can also minimize or outright eliminate pain, helping dentists perform complex procedures with minimal issues. Additionally, sedation dentistry offers several benefits, including:

  • Optional amnesia — Some sedatives can induce partial or complete amnesia during the procedure, which is beneficial for people with extreme dental phobia.
  • Increased efficiency — Reduced anxiety and fear can enable dentists to work more efficiently and potentially shorten appointment times.
  • Suppressed gag reflex — Sedation can suppress the gag reflex. This can help facilitate certain procedures that may otherwise be difficult due to a sensitive gag reflex.

For heightened anxiety or complex procedures, dentists may combine multiple sedation methods. This depends on your level of anxiety, the specific dental procedure, and your overall health status.

Sedation Procedures and Techniques

There are different types of sedation, ranging from mild relaxation to full general anesthesia. Each type of sedation is used to meet different anxiety levels and dental needs.

If you have dental fears, learning how sedation works can help make the whole idea less scary. Here's a breakdown of some common techniques and what it's like:

Inhaled Sedation

Laughing gas (nitrous oxide) is inhaled through a nasal mask. It acts on GABA receptors in the brain to help put you in a relaxed state while awake.

While under the effects of laughing gas, you may feel light, warm, and mildly euphoric. It’s a great option for short, simple treatments, such as cleanings or small fillings.

It’s also good for people with mild dental anxiety or a sensitive gag reflex. Lastly, its effects go away once the gas stops, making it a great option for patients who want to drive home after treatment.

Oral Sedation

Oral sedation involves taking a pill (or occasionally a liquid) approximately one hour before the dental appointment. Dentists usually use benzodiazepine pills like Valium or Halcion.

The effects of oral sedation vary depending on the dose. Generally, you’ll experience significant drowsiness and may even fall asleep during the procedure. 

The medication effectively manages anxiety and discomfort, and you’ll have little or no memory of the treatment afterward. Throughout the procedure, you’ll remain responsive but groggy.

Oral sedation is great for moderate anxiety and procedures that take a while to complete, like getting multiple fillings at once. Lastly, full alertness may return after 6 to 8 hours.

IV Sedation

With IV sedation, the sedatives are given directly into your bloodstream through a small IV in your arm. It works very quickly, and the level of sedation can be adjusted easily.

Depending on the dosage, you may feel deeply relaxed or even asleep. Most people have little memory of the treatment.

IV sedation is suited for more involved treatments like root canals or crown work, especially when you have notable fear or need efficiency in one or two sittings.

In some cases, an IV may be used for deep sedation, which minimizes your awareness and results in little to no memory of the procedure. This is typically used for serious anxiety, complex oral surgeries, or lengthy procedures.

General Anesthesia

General anesthesia induces a state of unconsciousness. It’s typically reserved for complex dental procedures or for people with severe dental anxiety that can’t be managed with other sedation methods.

Recovery from general anesthesia takes longer compared to other sedation methods. You’ll be monitored in a recovery area until you fully awaken and may require assistance getting home due to the lingering effects of the anesthesia.

General anesthesia is often administered through an IV and/or inhaled gases It results in near-zero awareness and recollection of the procedure.

How Safe is Sedation Dentistry?

Although sedation may sound intimidating, it’s considered safe and standardized under strict guidelines, provided you’re in skilled or prepared hands. 

Trained dentists and anesthesia professionals follow protocols to ensure sedation is both safe and effective:

  • Safety measures — Dentists will perform a comprehensive review of your medical history. They’ll also monitor your vitals throughout the procedure while having emergency equipment and reversal medications on hand.
  • Common side effects — Sedation may lead to drowsiness, dry mouth, mild nausea, and memory lapses during the procedure. Most of these side effects are mild and go away without any problems.
  • Rare complications — Allergic reactions to sedative drugs are rare, especially if your dentist is diligent. Additionally, respiratory issues can be avoided by administering sedatives properly.

The ADA (American Dental Association) sets standards, requiring sedation practitioners to maintain advanced life support certifications and consistent emergency readiness.

How Much Do Sedatives Cost?

Sedation fees vary depending on the method, time involved, and your location:

Sedation TypeCost Range (Approx.)Notes
Nitrous Oxide$20–$150 per sessionMild sedation, short-acting.
Oral Sedation (Pills)$175–$600For moderate relaxation.
IV Sedation$500–$1,000 per hourDeep sedation; billed hourly.
General Anesthesia$1,000 to $2000 per hourRequires an anesthesiologist.

Does insurance cover Sedation Dentistry?

Many dental plans don’t routinely cover sedation unless it’s deemed medically necessary (e.g., special needs, severe anxiety disorder, large-scale surgery).

Some partial coverage might exist for nitrous oxide or oral sedation, but it’s plan-specific. Fortunately, financing options, like CareCredit or in-house payment plans, can help reduce the cost.

Which Sedation Method is Best for You?

The ideal sedation method is tailored to your unique needs and anxieties. Open communication with your dentist is essential to determining the most suitable option for you.

Discuss your specific fears openly, whether it's needles, pain, or feeling a loss of control. Be transparent about your medical history, including:

  • Existing conditions
  • Current medications (including supplements)
  • Past reactions to medications or anesthesia

After a comprehensive physical examination of your airway, heart, and lungs, your dentist will recommend the safest option for you. For complex or unstable health conditions, your dentist may consult with your primary care physician.

How Does a Dentist Make a Tailored Sedation Plan?

Your dentist will create a personalized sedation plan based on your needs. These include:

  • Your health status
  • Current medications
  • Complexity of the procedure
  • Your anxiety level regarding the procedure

Sedation in dentistry isn’t solely about inducing unconsciousness. Instead, it involves finding the optimal level of relaxation that allows you to receive necessary dental care without experiencing undue anxiety or discomfort.

The most important thing is being honest about everything related to your health. You and your dentist are a team, and working together ensures your safety and a positive experience with sedation dentistry.
