Betamethasone is a type of glucocorticoid, or corticosteroid, with a long half-life. It can be taken orally, applied topically, or inhaled to achieve the required effect. Betamethasone is often used to treat skin conditions to reduce swelling, itching, redness, and irritation. This drug has also been found to have applications in the dental field by promoting healing and reducing swelling. Following more extensive dental procedures, patients often experience inflammation which leads to pain and a delay in the healing process. The use of betamethasone has been shown to lessen these complications. It is generally administered as a mouthwash with one soluble betamethasone tablet being dissolved in water. Patients usually experience a reduction in inflammation, swelling, and pain due to the effects of the drug. For oral lesions, betamethasone can also be administered via inhaler with the inhaler positioned in the mouth so that it is close to the site of the lesion.
