Explanation:
In dentistry, choosing an antibiotic depends on coverage of the typical oral bacteria, and penicillin is usually a first-line option for many odontogenic infections. Cephalexin, a first-generation cephalosporin, serves as the primary alternative when a patient cannot take penicillin due to allergy, because it has a similar spectrum against common oral pathogens such as streptococci and anaerobes and good oral absorption. This makes cephalexin the best choice for treating dental infections in penicillin-allergic patients. It isn’t used for viral or fungal infections, and it isn’t related to fluoride exposure.
