Dentists in Spain

My family is moving to Valencia for about 13 months. I am wondering about purchasing dental coverage before leaving home. I am not sure however if I even need that. The coverage would cost me $1000.00 CDN so it might be worthwhile to skip the coverage and pay for services as needed as its possible we won't even need dental services. Does anyone have any thoughts? What have you done? Is there anyone out there that has gone to a dentist in Spain? What were the costs? Any help or advice would be much appreciated.
