Oman today_ Consuming certain foods can play an important role in maintaining oral and dental health and in preventing issues such as tooth decay, gum inflammation, and bad breath. For example, green tea contains protective plant compounds that help reduce the growth of harmful bacteria in the mouth and, in addition to protecting the teeth, can also help keep breath fresh. Plain dairy products such as milk and yogurt, without added sweeteners, help prevent gradual tooth erosion thanks to their low acidity and contribute to strengthening tooth structure. Cheese, which is rich in calcium and phosphorus, also stimulates saliva production, helping to keep the mouth clean and reducing the risk of cavities and gum disease. Fresh fruits such as apples, strawberries, citrus fruits, and especially kiwi are excellent sources of vitamin C, which is essential for healthy gum tissue and for preventing inflammation. Alongside these, vegetables like carrots, pumpkin, potatoes, and broccoli provide vitamin A, which is vital for strengthening tooth enamel, while crunchy vegetables naturally help cleanse and stimulate the gums. Onions, particularly when consumed raw, contain strong antibacterial compounds that can help reduce harmful microbes in the mouth. Finally, drinking water helps keep the mouth moist and washes away food particles that can cause bad breath, supporting overall oral and dental health.
