My dentist (Dr. Amy from Silver State Smiles) merged with Image Dental and I have been in for a couple cleanings. Long story short - snickers candy bar pulled out an old filing, had my first root canal, got my NEW FAVORITE TOOTH!! I went for the more expensive zirconium (something like that) crown and it's the neatest tooth ever. It has ridges and edges just like a real tooth, not smooth like my filings or other crown. Go science!
