Patients have been asking about laser treatment for fungal nails. The laser podiatrists are using is the Pinpointe. According to this linked article (see below) it was approved for use in denistry by the FDA. So doctors using this process for toe nail fungus are using it off label. One doctor is quoted in this article says the only risk with using the laser is financial. Treatment IS expensive and NOT insurance approved. Any treatments for onychomychosis or toe nail fungus have a high reoccurance rate. Anywhere from 40-50%. Most of us who live in Southern California want to wear sandals in the summer. Fungal nails are not attractive. I assess my patients risk vs. benefit of using an oral or topical medication. I also have my patients bleach their white socks, clean their rubber sandals with lysol, put powder in their closed shoes, and clean their shower/bathtub with chlorine bleach.
