Maintaining good oral health with dentures is essential for preventing sores and infections. Poorly fitting or unclean dentures can rub against the gums, causing irritation, painful sores, and increasing the risk of fungal infections such as denture stomatitis. To prevent problems, dentures should be cleaned daily to remove plaque, bacteria, and food debris. Removing dentures at night allows the gums to rest and reduces moisture buildup that encourages infection. Regular dental checkups help ensure proper fit and allow early detection of oral issues. Healthy gums, good hygiene, and proper denture care are key to long-term comfort and oral health.
