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.
The temporary crown is also important, but for different reasons. The temporary crown is essential for comfort, appearance and to maintain the position of the adjacent teeth for the permanent crown. When a tooth is shaped for a crown, the more sensitive areas of the tooth are usually exposed. The temporary crown acts as a blanket for the tooth, insulating it from hot and cold foods and drinks. The temporary crown is also needed to help maintain the appearance of the tooth while the permanent crown is being made. A trimmed tooth can be unattractive without the temporary, especially if the tooth is near the front of the mouth.
