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.
After active treatment retainers will need to be worn. Removable retainers are worn full-time for the first 1 to 3 months. They are then worn only at nights for the next few months, phasing down to every other night for a few months, and eventually 1 or 2 nights a week.
