The goal of this clinical trial is to learn if low level laser therapy works equivalent to benzocaine in reducing the pain caused by separators in fixed orthodontic treatment. The main questions it aims to answer are:

Is there any difference in mean pain scores with Low Level Laser Therapy (LLLT) and 20% Benzocaine anesthetic gel of patients receiving elastomeric separators in fixed orthodontic treatment?

Researchers will compare low level laser therapy to benzoaine gel to evaluate reduction in pain

Participants will be applied low level laser at the appointment of separator placement and patient himself will apply benzocaine gel thrice daily at the site of separator placement. patient will use placebo on the other side. Gel and placebo would be applied for one month.

Patient will take the gel for 7 days.
