People with a pleural effusion may experience the following symptoms: 1  Shortness of breath. 2  Dry cough. 3  Pain. 4  Feeling of chest heaviness or tightness.
But why do you need braces spacers and why spacers hurt so much? The answers are right here. Once you decide on getting braces, the first thing your dentist do is place spacers back in your teeth. Braces spacers are placed mainly to create enough room for the anchors used to join the braces. The role of anchor is to slide over your back teeth smoothly and get attached to braces for extra support.
Hmmm you should ask you dentist, since you said they are telling you that before having braces they need to do teeth extraction, WHY is it? Is it damaged/chipped? If not then why they would do the extraction? You should make things clear before deciding since braces improves the alignment of the teeth.
