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.
The last negative aspect is that you may have to wear them longer than traditional braces to get the same results. Most adults have to wear braces for twelve to twenty months, possibly more. Once the braces are removed, a retainer will need to be worn to keep your teeth from moving back.
