Aphthous ulcers, sometimes called canker sores, form inside the mouth and cause pain and discomfort. While the sores usually resolve themselves in a few weeks, remedies are available to treat the symptoms and relieve pain. The aphthous ulcer remedies can take many forms including rinses, pastes, gels, and tablets. As clinicians treating the oral cavity, dental professionals are often among the first health care providers to recognize patients with canker sores. While many of these remedies are available over the counter, having a brand you are comfortable recommending or even dispensing from your practice can be a great way to provide a high level of service to your patients.
