There are a wide variety of oral health issues that can arise, but we are highly trained to identify and recognize them. Common problems include salivary problems, halitosis (bad breath), canker sores, cold sores (herpes simplex virus), thrush (fungal infections), and other infections and lesions in the mouth. We also can help diagnose periodontal disease (gum disease), macroglossia (an enlarged tongue), and geographic tongue. Sometimes we do encounter less common concerns, such as oral cancer, as well.
