What kind of disease is it that I have fleshy pimples on my teeth? A flesh-colored soft bump on the toothbed and the soft bump can drain pus. Sometimes healing often recurs, what is the problem. Most of the fistula openings are located on the buccal side of the affected tooth, but they can also open on the lingual and palatal side, or occasionally several teeth away from the tip of the affected tooth. In this case, a combination of hot and cold examination and electrodiagnosis should be performed to help determine the origin of the sinus tract and to avoid misdiagnosing a healthy tooth near the sinus tract opening as the affected tooth, and if necessary, to confirm the relationship between the sinus tract and the affected tooth using the missing tip method. Sinus tracts can also open in the skin and are called cutaneous sinus tracts. The sinus tract opening sometimes drains pus and sometimes does not, in a pseudo-healed state. The sinus type is less likely to turn into acute inflammation because pus can drain from the sinus tract opening. How to deal with it in the clinic, first of all, dental radiographs should be taken to observe the resorption of the apical tissue of the affected tooth. For teeth with retention value, root canal treatment can be done. Root canal treatment is divided into three steps, root canal preparation, root canal disinfection and root canal filling. For teeth that really have no retention value, they should be extracted as soon as possible.
