Have grinding habit. for back teeth 11, # 14 which type of gold crowns do you use best. yellow or white gold. how many carat gold you should use..

White Gold: It's harder than yellow gold, but it too can be worn away, so wear a bruxism appliance. It will be less expensive to replace a worn appliance than to fabricate new crowns.

Yellow plus NG: Yellow gold crowns are typically made from the relatively harder alloys because they need greater strength and wear resistance. After your final crowns are placed, you will need the nightguard (NG) to protect your teeth and crowns.
