<s>[INST] My orthodontist just told me he wants to put in springs instead of rubber bands. Apparently my rubber bands haven't been working well but they are the thinnest ones you can get and don't pull together very hard. Why wouldn't he try thicker rubber bands first? Is he stupid? [/INST] Hello,  Thanks for consulting HCM,   Here is Dr. Priyanka tiwari answering your query,   As per your query , No your doctor is not stupid , what happend is in orthodontic treatment doctor observe your tooth movement in your recall check up after then doctor decide what will be suitable for you , either Elastic , chain or Rubber band  or any other component.   So if your doctor decided to put rubbber band in treatment plan then it will be better for you . Hope I answered your query , Wishing you good health. </s>
