###Human: How to treat dentigerous cyst and odontoma present in the lower gums? ###Assistant: Hi. If the cysts are small, they can be left untreated. But the problem is that the cysts can create an infection later. They can also cause more issues like tooth mobility, bone loss or any other transformation. So it is better to remove it. Odontomas are developmental. They also create problems when they are left untreated. But again, there are chances of cyst formation and expansion later. So, if the oral surgeon suggests for removal of the cyst, try to go for it. I have gone through the reports (attachment removed to protect patient identity). It is better to remove the cyst. Currently, you do not have problems. If it is left untreated, it can form ameloblastoma in the future. You do not worry. These cysts are found in any person due to the impacted tooth.
