Children may experience toothaches for various reasons. Usually, cavities or gum disease are the most common causes of toothaches, but sport or play-related injuries to the mouth area can cause toothaches for children. Brush and floss the area thoroughly to allow for a better view. If the child is capable of rinsing with warm salt water and spitting, it may temporarily relieve symptoms related to gum problems. If you can see a pimple on the gums near the teeth, call a dentist right away. This is an infected tooth and needs treatment immediately. Children’s motrin can help reduce inflammation until the child can be seen by a dentist. There are over the counter benzocaine gels available to relieve symptoms, however, be sure not to give this to children under 2.
