<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hello, I have found a 5 mm hard non tender lesion in alveolar vestibular fold over my daughters right top premolar. She is 9 years old. It was 2 days ago. Its hard, sharply demarcated with distinct borders, painless. I did not notice any surrounding LAD. I am a family NP and am a bit worried. Lisa  <response>: Thanks for your query, I have gone through your query. The non-tender lesion over the premolar region could be a periapical cyst or fibrosis abscess secondary to tooth infection or exocytosis. Consult your oral physician and take radiograph to rule out infection. If it is tooth infection it has to be root canal treated. If it is exocytosis then no need of treatment its an excessive bone formation it wont trouble. I hope my answer will El you. Take care.
