Disclaimer: I am not saying that this method is safe and/ or effective. Best practice is emergency room for the first paragraph and dentist for the 2nd.
For cuts: someone helps you with a pressure point to temp stop bleeding or you make a tourniquet and temp stop blood flow, then just coat wound with the glue and gradually release pressure and restore normal blood flow. Tourniquets should NOT be on longer than 10 minutes.
You can also temporarily put crowns and fillings back in. It works great, but expect the dentist to tell you that you're nuts. And use a tweezers b/c your fingers will stick to the filling or crown.
