When a patient has dental caries, it can cause some damage to the gum tissue, resulting in the gums being in a state of acute inflammation. At this time, the gums may be particularly sensitive, especially to hot and cold stimuli, but this does not necessarily mean that the nerves in the gums are exposed. It is recommended that patients pay attention to a light diet and avoid overly hot or spicy foods, as well as hard foods that may irritate the sensitive gum tissue, leading to discomfort. Therefore, patients are advised to maintain a light diet, avoid spicy and irritating foods, and drink plenty of water. Additionally, it is crucial for patients to develop healthy oral hygiene habits. It is recommended that patients visit the hospital in a timely manner for consultation, and receive specific treatment plans based on the extent of the damage caused by the caries.
