MLD is usually caused by the lack of an important enzyme called arylsulfatase A. Because this enzyme is missing, chemicals called sulfatides build up in and damage the nervous system, kidneys, gallbladder, and other organs. In particular, the chemicals damage the protective sheaths that surround nerve cells.
What is a dental crown? The anatomy of a tooth can be divided into two basic parts -- the root and the crown. In a person with healthy gums and bone, the root of the tooth is covered by the gums and bone. The part of the tooth that is visible in the mouth, above the gum line on lower teeth and below the gum line on upper teeth, is called the clinical crown. A cemented restoration that partially or completely covers the outside of the clinical crown is referred to as a dental crown or cap.
Hence, a few precautions that you must take for your temporary crown are: 1  Do not eat sticky food that adheres to your teeth like chewing gum. It might grab and pull off the temporary crown. 2  Try not to use the side of your mouth with the temporary crown and chew with the other side of your mouth.
