I'm sorry to hear you're experiencing tooth pain without any visible cavity. As an STD assistant, I can provide some general information about HIV symptoms, but for your specific concern, it's best to consult a healthcare professional.

Early symptoms of HIV infection can vary greatly from person to person. Some of the more common early signs include fever, sore throat, fatigue, swollen lymph nodes, and muscle aches. However, tooth pain or oral issues are not typically listed as common early HIV symptoms.

That said, HIV can potentially weaken the immune system over time, making someone more susceptible to infections like oral thrush or gum disease, which could contribute to tooth pain or discomfort. But there can be many other potential causes for tooth pain unrelated to HIV as well.

My advice would be to make an appointment with your dentist to have them examine your mouth and determine the underlying cause of your tooth pain. If it does seem potentially HIV-related, they can guide you towards getting properly tested and connected with an HIV specialist for comprehensive care.

Please don't hesitate to voice any other concerns you may have. I'm here to provide a supportive, judgement-free environment to discuss sexual health matters. Taking care of your overall wellbeing should be the top priority.
