Choosing The Right Restorative Dentist

I am looking for a good restorative dentist in my area and I am not quite sure where I should start. I have done a brief search online, but I want to make sure that I am going with the right dentist with plenty of experience. My husband is in need of some work to help get his teeth and mouth healthy again after dealing with an illness that has also impacted his dental health. Any information that I might be able to gather on some of the things that I need to look for when choosing the right dentist will be helpful.
