Why does the tooth that fills end meet ache

When a tooth has a caries, it needs to be filled. However, it usually does not cause obvious pain after filling. Instead, it should be able to resume normal diet after filling and relieve the pain of cold and hot stimulation. If there is pain after filling, it may be because the tooth is not well filled. The filling material stimulates the dental nerve tissue. You need to go to the stomatology department for a review. Consider removing the filling material and pacifying the pulp. When the symptoms are relieved, you can re-perform a good base and filling. If there is already dental neuritis, you need to perform a perfect endodontic treatment before filling the teeth to prevent pain.
