Sedation dentistry is generally considered safe when administered by qualified and experienced professionals in a controlled environment. The level of sedation varies, ranging from mild to deep, and is tailored to the patient's specific needs and medical history. Common methods include oral sedatives, intravenous sedation, and nitrous oxide gas. While complications are rare, potential risks such as respiratory issues or allergic reactions exist, underscoring the importance of thorough pre-screening and monitoring during the procedure.
