When a patient has gingivitis, generally, dental cleaning can reduce some of the inflammatory irritation. However, there is no specific time frame for how long it will take to recover from gingivitis solely through dental cleaning. If a patient has gingivitis, it is still advisable to use some medications, such as oral anti-inflammatory drugs. For example, antibacterial drugs against anaerobic bacteria like metronidazole, tinidazole, or ornidazole, can be combined with some antibiotics, commonly amoxicillin or cephalosporins, or erythromycin. Additionally, patients must pay attention to oral hygiene, rinse their mouths promptly after meals, brush their teeth morning and night, and cultivate correct dietary habits. It is important to avoid spicy and overly hard foods in the diet. Furthermore, patients should ensure to eat plenty of fresh vegetables and fruits and schedule regular teeth cleanings to reduce the irritation caused by gingivitis.
