First crown I have had so I didn't know what to expect. Took at least 5 hours...think about that for a moment. Began having jaw problems and headaches. Took 5 years to figure out it was this crown that was way too big. Paid extra for a gold crown because I'm allergic to other metals, turns out it apparently wasn't gold after all. Just paid another dentist $1000 to fix it. I was begging to just have it , pulled but he insisted he knew what he was doing. Allergy is gone and it fits perfect. Believe me the headaches were awful and had no idea it was crappy dental work. Buyer beware. And after sitting in the chair mouth wide open @ 3 hours, I began involuntarily swallowing (reflexes) and she had the nerve to snap at me to stop it. Paid bill. Then they decided to add additional charges and billed me for more! Crazy!
