Dr. Kmak at Associated Dentists of NW Indiana did a terrible job on my crown, caused my a ton of pain, and generally was the worst dental/medical experience I've ever had. Here's the audit trail of events and an attached picture of their handiwork.
12/15/2015 - NW Dentist - initial visit - Dr. Kmak only looked in mouth for approx 20 seconds.
12/29/2015 - Crown prep, over 30 minutes late seeing me, felt ton of pain, only worked for five minutes or slightly less, left assistant to do bite check and sealant around temp. crown
12/30/2015, 8:30am approx - called in first part of day to complain about swelling mouth from sealant on my gums and get appointment scheduled.
12/30/2015, 12:50pm approx - mouth getting worse, called to see if they could see me any earlier at any time as swelling and pain was increasing; was told dentist not available, asked to see anyone, told no dentists were available all were gone on vacation, go to ER if needed
01/05/2016 - Dr. Kmak (dentist) at NW Dentist to get broken temporary fixed. He looked at it. I had to prod him with the fact that my four-day holiday weekend was spent in pain before I got a mumbled "sorry" and no further accountability taken. He left room after approximately 20-30 second exam and left assistant to re-seal tooth.
01/05/2016 - spoke with office manager at NW Dental about my concern. She offered to have me see a different dentist; I said no. She negociated $150 write-off on my remaining fees.
In effect I spent approximately $800 to feel a ton of pain, be treated poorly, and walk away to another dentist (who is awesome!). I did get the crown to take with me and it fit. And the tooth preparation was good enough for me new dentist.
So, visit this office after making your own assessment, but there is a better place out there.
