I notice metal in peoples hind teeth all the time. This is still a cosmetic need.
Food for thought. If teeth are constantly grinding against each other, is it good for the opposing teeth to constantly be grinding against a hard material like metal?
- realityking 7y agoI agree with your point about regularly noticing metal crowns but note that dental ceramics are way harder than metal. Dental ceramic is a 7 on the Mohs scale while gold and silver are in the 2.5 to 3 range.
- loco5niner 7y agoInteresting. And tooth enamel apparently ranks a 5.
- iends 7y agoIt’s not just about hardness. It’s about biocompatibility.
