Toothache is usually caused by:

• Missing / Broken teeth
• Gingivitis
• Cavity
• Bad crown installation
• Plaque
• Sleep apnea
• Temporomandibular joint disorder

Yes, toothache is a painful thing that sends a lot of people running straight to the dentist. We all know that toothaches have a nasty habit of striking in the night, thanks to changes in blood flow, and when the dentist’s office is closed. Sometimes, you just can’t go to a dentist.
