Conclusion: Pharmacological intervention utilizes either relative analgesia (nitrous oxide), conscious intravenous sedation or oral sedation, which can have undesirable side effects, risks and contraindications. These modalities increase the cost and availability of dental treatment.
Nitrous Oxide side effects
Across 4 first-hand reports, people mentioned a side effect 7 times (about 175 per 100 reports). The most common: brain damage, nerve damage, b12 destruction. User reports show what people notice — they can't tell you whether Nitrous Oxide is safe for you.

Nitrous Oxide and Midazolam Sedation: A Systematic Review and Meta-AnalysisConclusion: Two studies with 450 participants reported the time taken to recover from sedation, and the pooled estimate of SMD [95% CI] was obtained as -0.20 [-0.39, -0.01] and favored the combination technique. To conclude, the combination technique combines the pros and cons of both drugs in causing fewer adverse effects due to midazolam by reducing the total dose and also helps to provide better acceptance of nitrous oxide inhalation.
