The phrase "do dentists work on themselves" refers to the practice of dentists performing dental procedures on themselves. While this may seem unusual, there are several reasons why dentists might choose to do so.
One reason is that dentists are highly skilled professionals who are familiar with the latest dental techniques and materials. This means that they are well-equipped to perform dental procedures on themselves safely and effectively. Another reason is that dentists often have access to discounted or free dental care, which can make it more affordable for them to get the dental work they need.
