Fear No More: How Sedation Dentistry is Changing the Dental Experience

Sedation dentistry is a specialized field that combines the use of medication with dental procedures to help patients relax and minimize discomfort. Whether a simple cleaning or a more complex surgical procedure, sedation dentistry aims to make the experience as stress-free as possible.

Many people hold misconceptions about sedation dentistry, often confusing it with being “put to sleep” for a procedure. Questions like “Will I feel any pain?” or “Will I be completely unconscious?” are commonly asked, revealing a general lack of understanding about sedation dentistry. This article aims to clarify these misconceptions and provide a comprehensive look at this vital aspect of dental care.

What is Sedation Dentistry?

In sedation dentistry, pharmacological agents are used to calm and relax a patient before and during dental treatment. These sedative medications depress the central nervous system’s areas concerned with conscious awareness, allowing patients to undergo dental procedures with reduced anxiety, discomfort, and pain. Based on the patient’s needs and the complexity of the dental work, medications can be administered through inhalation, orally, or intravenously.

It has broken down barriers for individuals who have avoided dental treatment due to fear or anxiety, enabling them to receive necessary care for maintaining oral health. Moreover, it allows for more efficient and comfortable treatment experiences, even those undergoing complex dental procedures. By significantly improving patient comfort and cooperation, sedation dentistry has elevated the standard of care and expanded access to quality dental services.

What Sedation is Used in Dentistry?

Sedation dentistry is used to keep patients comfortable during dental procedures and is particularly beneficial for those with dental anxiety or those undergoing lengthy treatments. A variety of types of sedation are used in dentistry, including:

Nitrous Oxide

  • Also known as “laughing gas”. A mask is used to inhale nitrous oxide, which begins to calm the body within three or five minutes of inhalation. It leaves the system quickly, allowing patients to drive themselves home after the procedure.

  • Often used for less invasive procedures like dental cleanings, fillings, and minor tooth extractions.

Oral Conscious Sedation

  • This involves taking sedative medication, usually in pill form, about an hour before the procedure. Medications like triazolam (Halcion®), which is in the diazepam (Valium®) family, are commonly used. This form of sedation makes you quite dizzy, and you may even fall asleep but will still be able to communicate with the dentist.

  • Suitable for moderate procedures such as root canals, crown placements, and periodontal treatments.

Intravenous (IV) Sedation

  • This is the most profound level of conscious sedation that can be offered in a dental clinic. Sedative agents are directly injected into your circulatory system via an intravenous (IV) line. Most patients who experience IV sedation typically enter a sleep-like state and often have minimal or zero recollection of the procedure once they awaken.

  • Used for more complex and lengthy procedures like multiple tooth extractions, dental implant placements, or extensive periodontal surgery.

Each type of sedation is chosen based on factors like the patient’s anxiety level, the procedure length, health history, and personal preferences. Dentists must have special certification to provide some forms of sedation dentistry.

Are You Completely Asleep During Sedation Dentistry?

One of the most prevalent misconceptions about sedation dentistry is the belief that you’ll be “completely asleep” during the dental procedure. In reality, the level of consciousness you experience varies depending on the type of sedation administered.

With Nitrous Oxide, you remain fully awake and alert, albeit in a relaxed state, and can respond to verbal cues throughout the dental procedure. In the case of Oral Conscious Sedation, you might feel drowsy and even lightly doze off, but you’re generally still conscious and capable of responding to the dentist’s instructions.

However, you may not retain much memory of the procedure afterward. For Intravenous (IV) Sedation, the most profound form of conscious sedation available in a dental setting, sedative medications are directly infused into your bloodstream via an IV line. Most patients under IV sedation enter a sleep-like state and usually have little or no memory of the treatment upon waking.

It’s important to note that “being asleep” in sedation dentistry usually does not mean being fully unconscious, as in general anesthesia. Even with IV sedation, you are on the edge of consciousness and can be easily awakened.

So, to answer the question: No, you are generally not “completely asleep” during sedation dentistry unless general anesthesia is used, which is typically reserved for more complex surgical procedures or for patients who cannot be sedated by other means.

Is Dental Sedation the Same as Anesthesia?

A common question that arises when discussing sedation dentistry is whether dental sedation and anesthesia are the same. While both are used to make the patient more comfortable during dental procedures, they are not identical.

Dental Sedation refers to methods used to relax the patient and reduce pain and anxiety during dental procedures. Depending on the type of sedation (nitrous oxide, oral conscious sedation, or IV sedation), the patient may be awake but relaxed, drowsy, or on the edge of consciousness. However, they are generally not fully unconscious.

Anesthesia is often used to describe methods that induce varying levels of unconsciousness. Unlike local anesthesia, which numbs only a specific area, general anesthesia makes the patient unconscious from head to toe. Anesthesia is usually administered by an anesthesiologist or a dentist with specialized training.

Key Differences

  1. Level of Consciousness: Sedation generally allows for some level of consciousness, while anesthesia can induce complete unconsciousness.

  2. Administration: Sedation can often be administered by the dentist, while anesthesia may require a specialized anesthesiologist.

  3. Procedures: Anesthesia is typically reserved for more complex or invasive procedures, such as oral surgeries, where complete unconsciousness is necessary for the safety and comfort of the patient.

  4. Monitoring: Anesthesia usually involves more extensive monitoring of vital signs and may require a more extended recovery period.

Can You Feel Pain During Sedation Dentistry?

A common question among patients contemplating sedation dentistry is whether they will experience pain during the dental procedure. The answer to this question largely hinges on the type of sedation employed and the specific dental treatment. Nonetheless, the overarching aim of sedation dentistry is to reduce or completely eradicate pain and discomfort.

For instance, with Nitrous Oxide, you might still experience some sensations. Still, they are generally more tolerable than without sedation, and local anesthetics can be used to alleviate pain further. In the case of Oral Conscious Sedation, patients often feel relaxed and comfortable, with pain being significantly diminished or absent, mainly when combined with local anesthetics. As for Intravenous (IV) Sedation, primarily used for deep conscious sedation, patients are highly unlikely to feel any pain during the procedure and often have little to no memory of the experience afterward.

It's important to note that local anesthetics are frequently used with sedation dentistry to numb the treatment area, offering an added layer of pain relief.

Case Studies/Examples

Case Study 1: A Patient with Severe Dental Anxiety

Sarah, a 35-year-old woman, had avoided the dentist for over a decade due to severe dental anxiety. Her oral health had deteriorated, and she was in constant pain. After a consultation, her dentist recommended moderate IV sedation to help her relax during the necessary procedures, which included multiple fillings and a root canal. Sarah reported feeling relaxed and experienced minimal discomfort during the procedures. She has since returned for regular check-ups, and her oral health has significantly improved.

Case Study 2: A Patient Requiring Multiple Complex Procedures

Mark, a 50-year-old man, needed several complex dental procedures, including tooth extractions and dental implants. Due to the complexity and length of the procedures, deep sedation was recommended. This allowed the dentist to perform multiple procedures in one sitting without causing stress or discomfort to Mark. Mark successfully underwent all the necessary procedures in fewer visits, saving him both time and stress. He reported feeling no pain during the procedures and was pleased with the results.

Case Study 3: A Pediatric Patient

Emily, a 6-year-old girl, needed to have a cavity filled but was extremely fearful and uncooperative during initial attempts to treat her. Her pediatric dentist recommended minimal inhaled sedation (laughing gas) to help her relax. Emily was able to stay calm and relaxed throughout the procedure, allowing the dentist to complete the filling efficiently. Her parents were relieved, and Emily now has a more positive view of dental visits.

In each of these case studies, sedation dentistry played a crucial role in allowing the patients to receive the dental care they needed. Whether it was overcoming severe dental anxiety, enabling

the completion of multiple complex procedures, or helping a young patient have a more positive dental experience, sedation was the key to successful treatment.


In dental care, the introduction of sedation dentistry has been nothing short of revolutionary. Dental anxiety and fear have acted as significant barriers for too long, preventing countless individuals from seeking the oral care they need. Sedation dentistry effectively dismantles these barriers, offering a pathway to quality dental care that is both comfortable and stress-free.

Moreover, the psychological impact of a positive dental experience cannot be overstated. Sedation dentistry can act as a catalyst for a healthier way of life for individuals who have steered clear of dental visits for an extended period because of anxiety or previous negative experiences. Good oral health is intrinsically linked to overall well-being, and by making dental care more accessible and less intimidating, sedation dentistry plays a crucial role in promoting holistic health.

If you’ve been avoiding the dentist, now is the time to take action. Don’t let fear or misconceptions hold you back from achieving the oral health you deserve. Consult with one of the qualified dental professionals at Advanced Dental Care to discuss your options and determine if sedation dentistry is the right choice for you. It could very well be the decision that transforms your dental care experience, setting you on a path to a healthier, happier life.
