Hello, You may be experiencing a tooth erupting and some discomfort can be expected. Is this the first time you are noticing the teeth? Rinse the area, keep it as clean as possible and take some pain relief, anti-inflammatory medication. Do you think you have been grinding your teeth? This can be a reaction that causes some stiffness and discomfort similar to your symptoms. With tooth movement, this can change your bite and cause grinding. If the teeth have been present and are starting to move, then you must be careful and evaluate the situation for an infection. Are the teeth dark with decay? Is the gum covering part of the tooth and creating a pocket where something got caught? You can develop infections around the tooth (periodontal) or inside the tooth affecting the nerve. Spread of infection is dangerous and I do not recommend that you wait. Simple treatment and medication such as an antibiotic may control the situation untl you arrive home, but would require you seek professional help now. My advice is to see a dentist or oral surgeon specialist and explain you would like to delay treatment such as an extraction until you arrive home. Please answer some of my questions to help with your decision. I am glad to assist you with any additional questions and hope you will feel better soon.
