Laser dentistry has transformed modern dental care by offering more precise, minimally invasive, and patient-friendly treatment options. It is divided into hard-tissue lasers and soft-tissue lasers; each is designed for specific structures and clinical applications.
Understanding the differences helps patients know what to expect and how lasers can improve comfort and outcomes.
What Are Hard and Soft Tissues in Dentistry?
Each tissue type interacts differently with laser energy, so dentists use different wavelengths and devices for different procedures.
Hard Tissue vs. Soft Tissue Laser Dentistry: Key Differences
| Parameter | Hard Tissue Laser Dentistry | Soft Tissue Laser Dentistry |
|---|---|---|
| Primary Use | Treats teeth and bone | Treats gums and oral soft tissues |
| Common Procedures | Cavity removal, enamel reshaping, bone contouring, and tooth preparation | Gum reshaping, frenectomy, periodontal therapy, biopsy, ulcer treatment |
| Best For | Tooth decay, enamel defects, and bone surgery | Gum disease, gummy smile correction, soft tissue lesions |
| Laser Types Used | Er:YAG, Er,Cr:YSGG lasers | Diode, Nd:YAG, CO₂ lasers |
| Who Benefits Most | Patients needing fillings, tooth sensitivity treatment, and minimally invasive cavity removal | Patients with gum disease, excessive gum tissue, oral lesions, or cosmetic gum concerns |
| Pain Level | Often less than drilling; may still need local anaesthesia | Typically minimal; many procedures are done without injections |
| Bleeding | Minimal compared to traditional drilling | Very little bleeding due to laser cauterisation |
| Healing Time | Faster than conventional drilling or bone surgery | Faster healing with reduced swelling and infection risk |
| Noise & Vibration | No drilling noise or vibration | Silent and vibration-free |
