What is the primary use of codeine in dentistry?

The primary use of codeine in dentistry is to suppress cough and relieve pain. Codeine is an opioid analgesic, which means it is effective in managing pain by acting on the central nervous system to alter the perception of pain. In dental settings, it is often prescribed for patients who are experiencing moderate pain following procedures such as extractions or after root canal treatments.

Additionally, codeine has antitussive properties, making it useful in cases where patients may have a cough that is exacerbated by their dental condition or treatment. Its dual action—both as a pain reliever and a cough suppressant—makes it a valuable medication for dentists when managing discomfort in their patients.

The other options, while relevant to dental care, do not align with the primary indication for codeine. For example, while infection treatment is crucial, this often involves antibiotics rather than analgesics. Similarly, anxiety reduction is typically addressed through sedatives or anti-anxiety medications rather than opioids. Lastly, tissue healing is supported through other medications and therapies, such as anti-inflammatory or healing agents, rather than pain relievers like codeine.
