Temporary tooth repair

I was at a restaurant and bit something hard hidden in a piece of cake. It broke off part of my molar, and the jagged tooth cut into my cheek whenever I talked. I made an appointment to see the dentist the next day, and in the meantime, I bought a little container of orthodontic wax to smooth over the sharp part. The next day, the dentist told me I'd done the right thing. The container is so small that I keep it in my toiletries bag when I travel. I hope I never have to use it. — MF
