Hello, Your dentist most likely would refer you to an oral surgeon for an evaluation and possible biopsy if there is a great concern that the bumps may be cancerous. I would need more details to provide a reasonable opinion. Hard or soft? Moveable or fixed? Exact location? Has your sensitivity changed? Any concern with x-rays for this location? Sensitive bumps may be a result of an infection from a tooth or due to some trauma. Any habits that may be associated with this condition. A cyst, fibrous tissue, or excess bone may give this appearance as well. Changes, especially an increase in size and irregular border with pain, should be reported to your dentist. Monitor the area. Keep the area clean and follow good daily hygiene. Thank you for your inquiry. I do not think you should worry if your dentist only suggests checking the area in two weeks. You should be aware of the area and continue to monitor the condition. I am glad to offer assistance if you have additional details to share with me.
