What is Teeth Whitening?

Teeth whitening is a professional dental treatment designed to lift stains and discoloration from the surface of your teeth, restoring a lighter, more youthful shade. Unlike over-the-counter whitening kits, the treatment at Lienjang Dental Clinic uses advanced dental-grade whitening systems that provide visible results while keeping your teeth and gums safe.

How the process works at Lienjang Dental Clinic.

Our one-day whitening treatment is designed for both comfort and precision:
Oral Examination & Intraoral Photography — Our dentist examines your oral health, assesses your teeth shade, and takes detailed photographs so you can see your results clearly.
Pre-Whitening Preparation — The tooth surface is gently cleaned, and a protective gum barrier (glue dam) is applied to shield your gums from the whitening gel.
Professional Whitening Gel Application — A high-grade whitening gel is applied and activated under specialized light technology to lift deep-set stains.
Final Polish & Care Guidance — Your final tooth shade is compared with the original, post-treatment photographs are taken, and you’ll receive expert advice to maintain your bright new smile.
