Unfortunately, it’s unlikely your toothache will simply “go away.” Unless you have a piece of food stuck between your teeth that you can dislodge with dental floss, there’s a good chance a more serious issue is the culprit. This is why it’s best to see a dentist as soon as possible to try and rule out any underlying problems. Because there are many reasons a toothache can form, a thorough examination can identify issues early on, allowing for more immediate treatment.
