LDL cholesterol sometimes is called âbadâ cholesterol. A high LDL level leads to a buildup of cholesterol in your arteries. (Arteries are blood vessels that carry blood from your heart to your body.) HDL cholesterol sometimes is called âgoodâ cholesterol. This is because it carries cholesterol from other parts of your body back to your liver.
Spacers are usually used to put spaces in between teeth before braces are established. It can be agitating or painful, but patients are often warned not to pick at them or they will fall out. They are usually rubber, but sometimes they can be metal. They can be used when a patient's teeth are too close together.
Ideally, your teeth should fit easily within your mouth without any crowding or spacing issues. Also, none of your teeth should be rotated or twisted. The teeth of your upper jaw should slightly overlap the teeth of your lower jaw so that the pointed ridges of your molars fit into the groves of the opposite molar. Deviations from ideal occlusion are known as malocclusion.
