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.
After your braces are removed, your orthodontist (a special dentist who helps straighten teeth and correct jaw problems) will fit you for a retainer and tell you how long to wear it and when. For example, you might have to wear it all day for 3 months but then only at night after that. Some kids may wear their retainer only at night right from the start, but they may have to wear it for more than a year. The retainer keeps the teeth in line and you won't even notice it while you're sleeping!
