A tooth fracture can be temporarily covered with calcium hydroxide for pain relief. Start with a supraperiosteal nerve block (reviewed in a separate video), reviewed in a separate video. Dry the tooth first with gauze and then with air through a Yankaeur suction catheter or other device. The tooth must be completely dry for the calcium hydroxide to stick. Mix the calcium hydroxide and catalyst in a 1:1 ratio and apply to the exposed portion of the crown using a small brush or wooden end of a cotton tipped applicator. Allow a couple of minutes to dry. The patient will need dental follow up for definitive treatment.
