Hello there! I understand your concern. Wisdom teeth start erupting by the age of 17. It could be your second molar tooth which usually erupts by 12 to 14. Mild jaw aches, discomfort, gum swelling at the site of eruption are normal on any tooth eruption. You can attach pics of your teeth and jaw for examination.
Next Steps
If your symptoms are quite severe and unmanageable, please visit your nearest dentist.
Health Tips
Warm saline rinses multiple times a day is the best home remedy. You can also place an ice pack on the face of that side for relief. Avoid hot and spicy food till this settles. It should settle in a day or two.
Take care.
