 As my toothache intensified, I found that I could get a few moments relief by taking cold water in my mouth. So I started swigging water occasionally and then it became more and more regular. On a break in the workshop, I took my cup of water and my phone and went to call my dentist back in Wisconsin. Thankfully, even though it was the weekend, I was able to speak with him and I described the symptoms I was having and he thought it was likely due to an infection in a tooth that had had a crown put on it.
