Summary
This study tests two ways to activate a bleaching gel on teeth: using a laser or an LED light. Researchers want to see which method whitens better, causes less tooth sensitivity, and leaves teeth smoother. 45 adults aged 20-35 who want whiter teeth will take part in this single-session treatment.
