Gold is the way to go. I have four. I am a retired dental lab tech. If you don't mind the color of the gold it's the best restoration material . . . especially for molars. I made thousands of gold crowns, and when old amalgam fillings gave way, I wasn't going to use anything but Au. Ceramic, porcelain fused to metal crowns are great. I have a Lava crown on my canine and it's a spot-on match. However, I knew I often eat hard foods (e.g. nuts, granola, etc) and wanted a restoration that would last. First, gold being a noble metal does not react with the oral environment. It takes a licking and keeps on ticking. Second, gold isn't has hard as a porcelain restoration. It gives slightly like a real tooth, helping reduce the load on the periodontal membrane holding the tooth in its socket. Third, there's no chance of the porcelain cracking, shearing off, breaking, etc. Before the pandemic, I went in for my six-month checkup. My dentist was away, and I had done work for the dentist who was filling in that day. I reclined back in the chair, we chatted for a moment, opened my mouth, and as the dentist checked things out he said: "I see you know a thing or two about dentistry." I asked him to clarify, and he said "your gold crowns. That's what we dentists use as well." Granted, when I smile you can see my gold mandibular molars, but I really don't care. I'm not a GQ model, and value function over form. All I can say is that my gold crowns have stood up well these past 20 years. I made two of them myself! Gold is not high-tech, but I saw Roman gold crowns recently discovered in the ocean that looked like they had just been minted yesterday. Good choice of restoration!
