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.
Relapse means that the teeth can take up to one year or more to stabilize after treatment. If you had gaps between your teeth before treatment, the retention period will be longer. Usually, retainers are worn for as long a time as you have had your braces.
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.
