As well as the challenge of writing and placing a job advertisement for a new member of staff to join your dental practice, there is also the task of sifting through applications, interviews and deciding between candidates. All of these things cost your practice time and money.
Dental practices often have a short time frame to find a new member of staff. If this takes longer than you anticipated it could cost more money. Also there is the risk that you may end up employing someone based on their availability rather than their suitability for the job.
