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 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.
