<s>[INST] Hi I have an esix retainer which I only got last week. It is causing me incredible pain but am supposed to wear it everyday. It is digging into the skin that attached my power gums to my lip and also there is a sharp edge which digs on to my upper right cheek and is causing it get infected. What can I do to ease the settling of the retainer? [/INST] Thanks for your query, I have gone through your query. The possible cause for the pressure applied by the retainer can be either it is too active and has sharp borders. If the appliance is too active, then it causes pain in the teeth and gums, ideally the retainers should be passive. Regarding the pressure applied by the retainer on the gum causing damage to the gums is because of the extra extension of the retainer and the irregular sharp edges. Consult a dental surgeon and get the retainer in a passive state and also get the edges smoothened. I hope my answer will help you, take care. </s>
