If you have a tooth that hurts when you press it, it is recommended that you go to a professional oral health care institution to check and make a differential diagnosis of the disease, most commonly called chronic periapicalitis, chronic periapicalitis has typical chewing pain, which is often referred to as pain when eating, not pain when not eating, because the lesion itself is located at the root tip, so when eating or a press is transmitted to the root tip by the pressure, at this point there will be pain. The pain will occur at this time. And if no pressure is given, the pain is not particularly pronounced because it is chronic inflammation without stimulation. It is recommended to perform systematic root canal treatment for the tooth, and if there is pain when you press but not when you do not press, it is recommended to go to the dentistry department to check carefully what the problem is.
