Gum irritation is a common problem that can be caused by gingivitis, allergies, and dry mouth. However, it can be prevented with a few simple habits. According to dentist Sacheev Nanda, maintaining good oral hygiene is crucial. This involves brushing twice daily with a soft-bristled toothbrush, using mouthwash, and flossing regularly to remove plaque and food particles. Regular dental checkups are essential for early detection of issues like cavities and gum disease. A healthy diet also plays a vital role. Avoiding sugary foods that contribute to plaque buildup and staying hydrated by drinking plenty of water is recommended. Additionally, smoking and alcohol consumption can irritate gums, so it’s best to avoid or limit these habits. Finally, using a soft toothbrush to avoid gum injury and wearing mouthguards during sports can also help prevent gum irritation.
