When gingivitis occurs, if the inflammation is not controlled in time, severe cases may lead to purulent infections. Also, long-term chronic inflammation can cause the gingival tissue to shrink. As it progresses, this shrinkage may no longer adequately cover the roots of the teeth, leading to loose teeth, and in more severe cases, tooth loss. Therefore, when patients have gingivitis, they can undergo timely treatment, taking anti-inflammatory drugs orally for treatment. Additionally, diet and lifestyle are also important. It is vital to develop correct oral hygiene habits, avoid spicy and irritating foods, and eat more light foods rich in vitamins and vegetables to aid the nutritional repair of soft tissues.
