<s>[INST] My 12 year old son had an infection above one of his teeth with swelling to the face. the dentist scraped the area and suction out the infection and prescribed Amoxicillin. He has taken two of them as of today but the swelling is still increasing to his face and he has a temperature of 101. The dentist did advise that if the swelling should start to increase to the media range to the face to take to the ER. My concern at this moment is should we monitor for tonight or take him to the ER? [/INST] Hello, Antibiotic treatment usually takes at least 24 hours to be effective. Take all doses at correct prescription times. I suggest taking anti-inflammatory medication along with the antibiotic prescription at regular intervals. If possible, a combination of Tylenol and Advil can be very effective in controlling the spread of inflammation. Consult with your dentist for proper dosage based on weight and age of your child. I suggest calling the dentist to discuss the degree of increased swelling. This should help make the decision since your dentist is familiar with your sons condition. Any severe swelling should be treated at the ER. Sometimes one antibiotic is not effective and needs to be changed. Sometimes a stronger dose are required initially or during treatment to be effective. You must fully complete antibiotic prescriptions. If you are in any doubt about your sons' health, you cannot be wrong by making a trip to the ER. Close monitoring is advised as it is not uncommon for an increase in symptoms before the antibiotic is fully effective. Thank you for your inquiry. I hope your son will feel relief soon. </s>
