Overview: What Is Soft Tissue Laser Dentistry?
Soft tissue laser dentistry uses focused beams of light energy to cut, reshape, or remove gum tissue. Unlike traditional surgery with scalpels and sutures, lasers interact with tissue at a cellular level. The light energy is absorbed by water and pigmented tissue in the gums, allowing the laser to vaporize targeted cells while leaving surrounding tissue largely unaffected.
Soft tissue lasers are specifically designed to work on gum tissue, the lining of the mouth, and other non-bony structures. They differ from hard tissue lasers, which are designed to cut tooth structure or bone. In periodontics, soft tissue lasers are used for procedures ranging from gum disease treatment to cosmetic gum reshaping.
The two main types of soft tissue lasers in periodontal practice are diode lasers and CO2 lasers. Each operates at a different wavelength and has specific strengths depending on the procedure.
Types of Soft Tissue Lasers
Understanding the differences between laser types helps you know what to expect during treatment and why your periodontist may choose one over another.
Diode Lasers
Diode lasers operate at wavelengths between 810 and 1,064 nanometers. They are compact, portable, and relatively affordable compared to other laser systems. Diode lasers are absorbed well by pigmented tissue, hemoglobin, and melanin, making them effective for cutting soft tissue and controlling bleeding at the same time.
Diode lasers are the most widely used lasers in general dental and periodontal practice. They are well suited for bacterial decontamination of periodontal pockets, gingivectomy (removing excess gum tissue), frenectomy, and treating aphthous ulcers or herpetic lesions. Their ability to seal blood vessels as they cut means procedures often require no sutures.
CO2 Lasers
CO2 lasers operate at a wavelength of 10,600 nanometers, which is strongly absorbed by water. Since gum tissue is rich in water content, CO2 lasers are extremely precise for soft tissue surgery. They provide excellent hemostasis (bleeding control) and create a very clean surgical field.
CO2 lasers have been used in medicine and dentistry for decades. In periodontics, they are often preferred for procedures that require precise tissue removal, such as gum contouring, removal of benign oral tumors, and treatment of leukoplakia or other mucosal lesions. CO2 laser systems tend to be larger and more expensive than diode lasers.
Diode vs. CO2: Key Differences
Both lasers are effective for soft tissue procedures, but they have different characteristics. Diode lasers penetrate deeper into tissue, making them better for pocket decontamination and bacterial reduction. CO2 lasers are more superficial in their action, providing cleaner cuts with minimal thermal damage to adjacent tissue. Diode lasers are more portable and less expensive. CO2 lasers offer greater precision for delicate cosmetic and surgical work. Your periodontist will select the laser type based on the specific procedure and your clinical needs.
What to Expect During Laser Gum Treatment
Laser gum procedures are typically performed in your periodontist's office with local anesthesia. Many patients report that laser procedures feel less invasive than traditional surgery.
Before the Procedure
Your periodontist will examine your gums, take X-rays if needed, and determine whether laser treatment is appropriate for your situation. Not every periodontal condition is best treated with a laser. For example, lasers cannot remove hardened calculus (tartar) below the gumline. Scaling and root planing with ultrasonic or hand instruments is still needed for that step.
If you are having a laser-assisted procedure, your periodontist will explain the specific type of laser being used, what it will do, and how it will feel. You will receive local anesthesia to numb the treatment area.
During the Procedure
You will wear protective eyewear during the procedure. The periodontist will direct the laser fiber or beam at the treatment area. You may smell a slight odor as tissue is vaporized, which is normal. Most patients report little to no discomfort beyond what the anesthesia covers.
For pocket decontamination, the diode laser fiber is inserted into the periodontal pocket to kill bacteria and remove diseased tissue lining the pocket wall. For gingivectomy or gum contouring, the laser precisely removes or reshapes excess tissue. Procedures are often faster than their scalpel-based equivalents.
How Long Does It Take?
Most soft tissue laser procedures take 15 to 60 minutes depending on the extent of treatment. A single-tooth gingivectomy may take 10 to 15 minutes. Laser decontamination of periodontal pockets across a full mouth may take 45 to 60 minutes. Many patients are able to return to normal activities the same day.
Recovery and Aftercare
One of the main advantages of laser gum treatment is the faster, more comfortable recovery compared to traditional surgery.
The First Few Days
Most patients experience mild soreness for 1 to 3 days after a laser procedure. Swelling is typically minimal. Because the laser cauterizes blood vessels as it works, there is usually little to no bleeding after the procedure. Over-the-counter pain relievers like ibuprofen are usually sufficient for any discomfort.
Your periodontist may recommend a soft diet for 2 to 3 days and ask you to avoid brushing directly on the treated area for a short period. Warm salt water rinses can help keep the area clean.
Healing Timeline
Soft tissue treated with a laser generally heals faster than tissue cut with a scalpel. The laser creates a coagulation layer over the wound that acts as a biological bandage. Most patients see significant healing within 7 to 14 days. Full tissue maturation may take several weeks.
Follow-up appointments allow your periodontist to check healing and evaluate whether additional treatment is needed. For periodontal pocket decontamination, your periodontist will re-measure pocket depths at a follow-up visit to assess improvement.
Long-Term Maintenance
Laser treatment is not a one-time cure for gum disease. Periodontal maintenance visits every 3 to 4 months are still essential to prevent recurrence. Good daily oral hygiene, including brushing twice daily and cleaning between teeth, remains the foundation of gum health after any procedure.
Cost Factors
Laser gum procedures may cost slightly more than their traditional counterparts due to the cost of the equipment. However, the reduced need for sutures, shorter procedure times, and fewer post-operative complications can offset some of that difference.
Laser gingivectomy or gum contouring typically costs $200 to $500 per tooth. Laser pocket decontamination as an adjunct to scaling and root planing may add $100 to $300 per quadrant on top of the base scaling and root planing fee. Laser frenectomy costs $250 to $1,200 depending on complexity.
Dental insurance coverage for laser procedures varies. Some plans cover laser treatment at the same rate as the equivalent traditional procedure. Others may classify laser treatment as elective and offer limited or no coverage. Check with your insurance carrier before scheduling. Costs vary by location and provider.
When to See a Specialist
Consider seeing a periodontist trained in laser dentistry if you have gum disease that has not responded well to standard scaling and root planing, if you need gum reshaping for cosmetic or functional reasons, or if you have a frenulum attachment that is causing gum recession or a gap between your front teeth.
Laser treatment is also a good option if you are anxious about traditional gum surgery, have a medical condition that makes bleeding control important (such as taking blood thinners), or simply want to explore less invasive treatment options. Not every periodontist offers laser procedures, so ask about their training and the type of laser they use.
Find a Periodontist With Laser Training
A periodontist is a dental specialist with 3 additional years of training beyond dental school in treating gum disease and performing gum surgery. Some periodontists have additional training and certification in laser dentistry through organizations like the Academy of Laser Dentistry.
Use our directory to find a periodontist near you who offers laser gum treatment. When calling to schedule, ask whether they use diode lasers, CO2 lasers, or both, and whether they recommend laser treatment for your specific condition.
