Patients with gingivitis can eat grapes, as grapes contain rich vitamins and nutrients, which can be very beneficial to the body. However, it is recommended that patients rinse their mouth and brush their teeth immediately after eating grapes to remove any residual grape juice. Since grapes are sweet, leaving residues in the mouth can lead to bacterial growth and worsen gingivitis. Therefore, patients can consume a moderate amount of grapes, and eating other fresh fruits can also be beneficial for inflammation recovery. In daily life, it is also recommended for patients to eat more fresh vegetables and fruits. For gingivitis, it is important to identify the causes, whether it is due to wisdom teeth, periodontitis, or apical periodontitis. In such cases, it is generally advised to seek medical advice and receive appropriate treatment under the guidance of a doctor.
