Why does beer or alcohol give me a toothache?

Beer or alcohol can contribute to toothaches due to their acidic content, which can erode tooth enamel and lead to sensitivity. Additionally, alcohol can cause dehydration, reducing saliva production and increasing the risk of dental problems. If you have existing cavities or gum issues, the irritation from alcohol can exacerbate pain. It's important to maintain good oral hygiene and consult a dentist if you experience persistent discomfort.
