The development of teeth and those teeth pushing through the gums is called teething. Teething typically begins in young children as early as four months old and may continue until they reach two years of age. Experts report that teething children may experience pain and discomfort in the gums. Additionally, children may have symptoms such as vomiting, diarrhea, or a slight increase in body temperature.
If teething pain becomes severe, an over-the-counter (OTC) pain reliever such as ibuprofen (Advil, Motrin) or acetaminophen (Tylenol) may be taken to reduce pain and discomfort. Ibuprofen and acetaminophen work by blocking chemicals in the body that cause pain, fever, but ibuprofen may reduce swelling of irritated gums. They are available in formulations such as syrups and chewable tablets. Side effects of ibuprofen include nausea, diarrhea, and upset stomach. Side effects of acetaminophen include itching and tiredness.
