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
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 it's an excessive bone formation it won't trouble. I hope my answer will El you. Take care.
