The presence of loose tooth is a concern for the anesthesiologists during oxygenation and laryngoscopy. Although patients are routinely explained about the risk of inadvertent tooth damage or even the need for extraction, still the resultant cosmetic disfigurement and possibility of tooth misplacement into the oropharynx or laryngopharynx keep the anesthesiologists on their toes. Various techniques have been described to save the tooth especially the loose incisors during laryngoscopy like tying the tooth at its base by a suture or using molar approach  or paraglossal approach  to intubation with various blades. However, the preliminary stage of mask ventilation is often overlooked and is not been adequately addressed by researchers till now. Mask ventilation can itself be enough to dislodge a loose tooth by the shear pressure of the mask cushion on the lower jaw or the pressure and friction on the incisors and canine teeth of the lower jaw by the upper jaw or vice versa. Not much information is available in the literature on the “tooth saving” technique of mask ventilation.
We at our clinical practice are following a modified technique of mask ventilation in patients with loose incisors or canines – the open jaw technique. After preoxygenation, when anesthesia is induced, we open the mouth of the patient by jaw thrust and keep it open without letting the anterior part of both the jaws bearing the incisor and canine teeth touch one another [Figure 1]. This way the pressure on the loose tooth during mask ventilation that would otherwise be exerted by a closed mouth technique is avoided. In our experience, this carries a great safety profile in terms of protecting the loose tooth and at the same time allows easy mask ventilation. We hope the anesthesia fraternity would benefit from our technique which we fondly call the “Medanta Awe.”
