From the Guidelines
For treating canker sores on the tongue and lips, the most effective approach is to use a combination of topical anesthetics, antiseptic oral rinses, and good oral hygiene practices, as recommended by the most recent and highest quality study 1. To manage canker sores, start by applying a topical anesthetic preparation, such as viscous lidocaine 2%, 15 mL per application, to reduce pain and discomfort 1. Additionally, use an antiseptic oral rinse, like 1.5% hydrogen peroxide mouthwash or 0.2% chlorhexidine digluconate mouthwash, twice daily to reduce bacterial colonization of the mucosa 1. Some key considerations for managing canker sores include:
- Avoiding spicy, acidic, or rough foods that can irritate sores
- Using a soft-bristled toothbrush to prevent further irritation
- Practicing good dental and mouth hygiene, including regular brushing and flossing
- Evaluating the use of dental appliances, such as braces or dentures, to ensure they are not causing irritation 1
- Considering the use of a topical corticosteroid, such as betamethasone sodium phosphate or clobetasol propionate, to reduce inflammation and promote healing 1 It is essential to note that canker sores can be caused by immune system reactions, minor injuries, or nutritional deficiencies, particularly B vitamins, iron, and zinc. Maintaining good oral hygiene and addressing potential triggers can help prevent future outbreaks. If sores are large, extremely painful, last longer than two weeks, or occur frequently, it is recommended to consult a healthcare provider for further evaluation and treatment.
