DENTIN
Alloys are harder than the components.
Topaz is softer than quartz but harder than apatite on the Mohs scale of mineral hardness. It has a hardness of 8 on the scale, whereas quartz has a hardness of 7 and apatite has a hardness of 5.
Dentin is a hard tissue that lies beneath the enamel in a tooth, providing support and protection to the inner structures. It is not as hard as enamel but harder than pulp, the innermost part of the tooth.
The mineral that is softer than a steel file but harder than glass is typically quartz. Quartz has a hardness of about 7 on the Mohs scale, while glass usually ranges around 5.5, and steel files can be harder, often rated around 6.5 to 7.5 depending on the specific type of steel. Therefore, quartz fits the criteria of being softer than a steel file but harder than glass.
Calcite is a mineral that is harder than gypsum but softer than fluorite on the Mohs scale of mineral hardness. Calcite has a hardness of 3, while gypsum has a hardness of 2 and fluorite has a hardness of 4.
The root of a tooth are covered with cementum which is much softer than enamel.
Silver is harder than gold but softer than copper.
No, diamonds are harder than enamel. Diamonds rank as the hardest natural material known, scoring 10 on the Mohs Scale of Hardness, while enamel, the outer layer of teeth, ranges from 5 to 7 on the scale.
Dentine is a mineralized tissue that makes up the majority of a tooth's structure. It lies beneath the enamel covering of the tooth and is softer than enamel but harder than bone. Dentine plays a crucial role in supporting and protecting the inner pulp of the tooth.
It's softer. #1 softest, #2 slightly harder, #3 harder than #2, etc.Softer.a #1 pencil is softer than a#2 pencil
Enamel is the hard, outer material found on teeth. Underneath the enamel is dentin, which is softer and makes up most of the tooth. If a person has bad acid reflux, the enamel on their teeth comes off, and their teeth become very sensitive to temperature and certain foods.

Limestone is a form of calcium carbonate that is softer than marble but harder than chalk. It is commonly used in construction materials and can be found in different shades depending on the mineral impurities present.
Hardest compont of the human body is the Enamel of the tooth (above gum line - gingivi) with approximately 95% calcium concentration The Dentin of the tooth (within enamel) has approximately 80% concentration of calcium
