The consequences of untreated pulp polyps are as follows: 1. The pulp cavity is open, the soft tissue of the pulp appears capillary hyperplasia under chronic stimulation, and it is easy to break down when chewing, and there is a lot of blood leakage, which makes the mouth smell corrosive bad breath. 2. The chronic hyperplasia of pulp polyps, which are nodular and cover the tooth surface, will produce chewing pain, affect chewing efficiency, and cause obstacles to the digestion and absorption of food. 3. The pulp polyp will gradually destroy the root canal structure, forming root canal resorption and gradually weakening the root canal wall, with the risk of root fracture or tooth loosening. 4. The pulp polyp will form apical granuloma or cyst after breaking through the apical hole.
