Why have a toothache in more than one tooth?

A toothache in more than one tooth can be caused by several factors, including dental decay, gum disease, or infection that affects multiple areas. Poor oral hygiene can lead to plaque buildup, resulting in cavities or gingivitis that can trigger pain in multiple teeth. Additionally, issues like teeth grinding or jaw problems may cause discomfort across several teeth. If experiencing this, it's important to seek dental care for a proper diagnosis and treatment.
