Orabase Protective Paste is a medicated dental paste used to treat a variety of oral conditions, including canker sores, denture sores, and other mouth sores. It contains two active ingredients, benzocaine and aluminum hydroxide, which work together to numb the affected area and protect it from further irritation. Benzocaine is a local anesthetic that helps to numb the area and provide pain relief, while aluminum hydroxide acts as a protective barrier that helps to soothe and protect the sore from further irritation. The paste also contains other ingredients such as petrolatum and mineral oil, which help to create a thick, protective layer over the affected area. To use Orabase Protective Paste, clean and dry the affected area before applying a small amount of the paste directly to the sore. You can use your finger or a cotton swab to apply the paste. The paste should be left on the sore for several hours or overnight before gently rinsing it off with water. You can repeat the application up to four times a day or as directed by your dentist or healthcare provider.
