Bad breath, or halitosis, is often overlooked but should be addressed when persistent. Keep records of your diet, medications, surgeries, and health history to discuss with your dentist. Factors like diet, oral hygiene, and tobacco use contribute to bad breath. It is important to adhere to a consistent routine of brushing, flossing, and optimal oral care. Seek personalized prevention advice from your dentist, who can provide information on reducing and preventing bad breath.
