TLDR : Answer Summary
Yes, as an American traveling on a tourist visa for less than 30 days, you can leave Thailand to visit Vietnam and re-enter Thailand without needing to apply for another tourist visa. Upon your return, you will receive a new visa-exempt stamp for either 30 or 45 days, depending on current regulations. When exiting Thailand, your original visa becomes void, so there's no need for a re-entry permit. Just ensure you have a valid ticket leaving Thailand within the allowed period.
