This tag implies that the bands and artists are Serbian or originated in Serbia. Music represented by this tag is often highly commercial. Other, possibly better, Serbian tags are, for example Novi Val or nova srpska scena.
For how long do I need to wear retainers? It takes time for the bone and all the tissues around your teeth to reorganise and therefore it is necessary to use retainers until your bite stabilises. In the first month after the braces are removed, the risk of relapse is very high.
For the average patent, you will wear your removable retainer full-time for the first 3-6 months, and thereafter only while sleeping. If your orthodontist recommends a period of time longer or shorter than this, he or she is protecting your smile.
