What is Oral Sedation: The Ultimate Guideline!

Oral sedation is an excellent alternative to traditional sedation methods that have been used in dental procedures. It involves taking medication orally to help relax and calm the patient before and during the dental appointment. In this ultimate guideline, we will be discussing everything you need to know about oral sedation, its benefits, potential side effects, and how it works.

What is Oral Sedation?

Oral sedation is a type of conscious sedation used in dental procedures to help the patient relax and feel comfortable. It involves taking medication orally, usually in the form of a pill, to help the patient feel calm and at ease during the dental appointment. Oral sedation is suitable for patients who suffer from dental anxiety or for those who undergo a complex dental procedure.

How Does Oral Sedation Work?

Oral sedation medications work by suppressing the central nervous system, which leads to a feeling of relaxation and calmness. It helps the patient forget the procedure and alleviate anxiety. The medication typically takes about 30 minutes to an hour to take effect, and the effect can last for several hours.

The dosage and the type of medication used in oral sedation are determined by the dentist based on the patient’s needs and medical history. Nitrous oxide is a common medication used for oral sedation because it is fast-acting, and its effect wears off quickly, allowing the patient to drive themselves home after the procedure.

What are the Benefits of Oral Sedation?

Oral sedation offers several benefits, including:

  • Reduced dental anxiety and fear
  • Increased comfort during dental procedures
  • Ability to complete complex dental procedures in one appointment
  • Reduced gag reflex
  • Quicker recovery time compared to other sedation methods
  • Safe and effective for most patients

What are the Potential Side Effects of Oral Sedation?

Oral sedation is generally safe and has few side effects. Some patients may experience mild side effects such as drowsiness, dry mouth, and headache. It is crucial to discuss any potential risks or side effects with your dentist before undergoing oral sedation. It is important to note that oral sedation requires the patient to have a designated driver to take them home after the procedure.

Who is a Candidate for Oral Sedation?

Oral sedation is suitable for adults who suffer from dental anxiety, fear, or discomfort during dental procedures. It is also appropriate for patients who undergo complex dental procedures that require a longer appointment time. Patients who have difficulty sitting still or have a strong gag reflex may also be a candidate for oral sedation.

Who Should not Undergo Oral Sedation?

Oral sedation may not be suitable for patients with specific medical conditions or who are taking certain medications. It is essential to inform your dentist of any medical conditions, medications, or supplements you are currently taking before undergoing oral sedation. Patients with sleep apnea, severe respiratory problems, and liver or kidney disease may not be a candidate for oral sedation.

What to Expect During Oral Sedation?

Before the dental appointment, the dentist will review the patient’s medical history and discuss the oral sedation process, including any potential risks or side effects. The patient will receive instructions on what to eat or drink before the appointment and the dosage and medication to take.

On the day of the procedure, the patient takes the prescribed medication at the appropriate time. It is recommended that the patient have a designated driver or someone to accompany them home after the procedure. The dentist will monitor the patient’s vital signs and ensure they are comfortable. The patient will feel calm and relaxed throughout the procedure and may not remember much of it.

What are the Advantages of Oral Sedation over Other Sedation Methods?

Oral sedation has several advantages over other sedation methods, including:

  • No pain or discomfort associated with needle injections, which are necessary for intravenous sedation or general anesthesia
  • Less expensive than other forms of sedation
  • Quicker recovery time compared to general anesthesia or intravenous sedation
  • Can be administered at home, making it more convenient for the patient


Overall, oral sedation is an excellent alternative to traditional sedation methods, providing patients with a more comfortable and relaxed dental experience. It is safe, effective, and well-tolerated by most patients. If you suffer from dental anxiety or require complex dental work, oral sedation may be the right choice for you. Schedule a consultation with your dentist to discuss your options and see if oral sedation is the right choice for your dental needs.
