According to the Academy of General Dentistry, When one has braces on teeth, those teeth need extra attention to protect them from decay, staining and gum disease. One should also take precautions to avoid damaging the braces. For example, one must avoid eating chewy or sticky foods including sweets, eating hard and crunchy foods such as raw vegetables. It is also advised to avoid breathing excessively through the mouth or pushing the tongue against the teeth.
