Laser Dentistry Waterloo
In recent years, laser dentistry has superseded many traditional dentistry practices, making treatments more precise and less painful. This newer style of dentistry utilizes intense beams of light projected by a dental laser.
Dental lasers can be used to perform a wide variety of treatments, including soft tissue shaping and removal.
The FDA deemed laser dentistry to be safe for public usage in 1990. Since then, many dentists have incorporated dental lasers into everyday procedures – reducing bleeding, anxiety and post-treatment recovery times. The beauty of dental lasers is that they damage far less of the surrounding tissue than traditional techniques – which means less discomfort and pain.
Here are some of the other benefits associated with laser dentistry:
- Faster healing and tissue regeneration.
- Preservation of more of the natural tooth.
- Reduced bleeding during and after treatment.
- Reduced need for anesthesia.
- Reduced need for stitches and sutures.
- Reduced risk of bacterial infections after procedures.
How Can Laser Dentistry Help Me?
Laser dentistry is incredibly versatile and plays an important role in a growing number of common dental procedures. Though laser dentistry is most notably associated with cosmetic treatments, it is equally effective for preventative purposes.
Here are some of the ways that dental lasers can be used:
- Tooth preparation – Prior to laser dentistry, a drill would be required to prepare the tooth for a filling. Lasers can now completely eliminate the need for drilling and anesthesia. Lasers also successfully kill oral bacteria around the surgical site.
- Reshaping soft tissue – Dental lasers can dissolve soft tissue to expose more of the natural tooth (crown lengthening), reshape soft tissue to make “gummy smiles” more attractive, and remove uncomfortable soft tissue folds caused by denture wear.
- Frenectomy – Lasers can improve speech and the feeding habits of babies, children and adults by untying the tongue.
- Tumor removal – When benign tumors have formed in the soft tissue areas of the mouth, a dental laser can completely remove them without causing pain.
- Whitening – Lasers can greatly expedite the tooth whitening process by increasing the activity of the particles in the peroxide bleaching solution.
- Biopsy – Lasers are sometimes used to perform a biopsy on suspicious areas of soft tissue. This biopsy procedure can be performed instantly and with great precision.
How Are Laser Procedures Performed?
Different types of dental laser have been created to treat different conditions. Each laser uses a different wavelength of light, which predicates its primary use. The most common types of dental laser are carbon dioxide lasers and diode lasers, which are usually employed to treat soft tissue problems. The dentist will decide which type of laser is most appropriate to use after conducting X-rays and a thorough examination.
The laser beam is extremely bright, and special glasses will be provided to protect the eyes. The dentist will then direct the beam at the affected area and carefully dissolve the soft tissue, harden the filling or whiten the teeth.
The procedure will take far less time than conventional methods, and cause far less anxiety and discomfort. The only real disadvantage of laser dentistry is that it can prove to be more expensive.

What to Expect From a Laser Dental Procedure
Dental lasers use focused light energy to perform tasks that traditionally required scalpels, drills, or aggressive scaling — removing or reshaping soft tissue, cleaning out infection in gum pockets, treating cold sores, and helping with certain decay-removal scenarios. Different wavelengths target different tissues, which is why several types of lasers exist for different procedures. The patient experience varies by procedure but generally involves less bleeding, less swelling, and faster healing than the equivalent traditional approach.
Before a laser procedure, your dentist explains what is being done, why a laser is the right tool for this case, and what to expect during and after. Local anaesthetic is used for procedures that would otherwise need it (such as gum surgery or decay removal); some minor procedures (such as cold sore treatment or removing a small piece of soft tissue) need only topical numbing or no anaesthetic at all. Everyone in the room wears protective glasses tinted for the specific laser wavelength being used.
During the procedure, the laser tip is positioned near the target tissue and pulses of light energy are delivered. Most patients report little to no sensation beyond a warm feeling. There is no drilling vibration or the loud sound that some patients find unsettling about traditional dental equipment. Bleeding is typically minimal because the laser seals small blood vessels as it works, which is one of the reasons recovery tends to be quicker. The same effect reduces the need for sutures in many soft-tissue procedures.
Procedures Where Dental Lasers Are Useful
Lasers are not the right tool for every dental procedure, but they have specific applications where they offer real advantages. Your dentist may suggest a laser approach for:
- Reshaping or trimming gum tissue for cosmetic crown lengthening or to expose more of a tooth before restoration
- Removing small benign soft-tissue growths, fibromas, or lesions
- Treating early-stage gum disease by cleaning bacteria from gum pockets (laser-assisted periodontal therapy)
- Treating cold sores or aphthous ulcers to speed healing and reduce discomfort
- Performing a frenectomy (releasing a tight lip or tongue tie), especially in infants and young children
- Removing soft tissue for biopsy with reduced bleeding
- Assisting with whitening procedures by activating bleaching agents
- Removing very early-stage decay in some cases (though most fillings are still placed using traditional handpieces)
- Reducing tooth sensitivity by sealing exposed root surfaces
For many traditional dental procedures (large fillings, root canals, crown preparations, extractions), conventional handpieces and instruments remain faster, more precise, or simply better suited to the task. The decision to use a laser is based on whether it offers real benefits for the specific case, not on novelty.
Recovery After a Laser Procedure
Recovery from laser dental procedures is typically shorter and more comfortable than recovery from the equivalent procedure done with traditional instruments. Soft-tissue procedures usually involve minimal bleeding, less swelling, and reduced post-operative discomfort. Many patients return to normal activities the same day and need only over-the-counter pain medication, if anything.
Specific aftercare depends on the procedure. After gum reshaping or other soft-tissue work, you typically avoid hard, crunchy, or spicy foods for a few days and rinse gently with warm salt water to keep the area clean. After laser periodontal therapy, follow-up cleaning visits every three to four months become part of maintaining the result. After a frenectomy, gentle stretching exercises may be recommended to prevent the tissue from reattaching. Your dentist provides written instructions specific to your procedure.
Patients with very specific medical conditions, certain medications (especially blood thinners), or active oral infections may not be suitable candidates for some laser procedures. This is assessed during the consultation along with whether the laser approach offers real advantages over conventional treatment for your specific situation.
Cost and Insurance Coverage
Laser dental procedure cost varies by what is being done. A small soft-tissue procedure costs less than a larger gum surgery or a periodontal therapy session. Trillium follows the current Ontario Dental Association Suggested Fee Guide for laser procedures, and we provide a written estimate before treatment starts.
Insurance coverage for laser procedures varies depending on the procedure code used. Some procedures (such as gum surgery) are covered under standard surgical codes regardless of whether a laser or scalpel is used. Other procedures may have specific codes that some plans cover and others do not. We submit a pre-determination to your insurer before treatment to confirm what is covered, and we can discuss payment options for any portion not covered.
Frequently Asked Questions
Does the laser hurt?
Most patients describe laser dental procedures as more comfortable than the conventional equivalent. Local anaesthetic is used for any procedure that would normally require it. Some minor laser treatments (such as treating a cold sore) require no anaesthetic at all because the sensation is minimal.
Will I need sutures?
Often no, especially for small to moderate soft-tissue procedures. The laser seals small blood vessels as it works, which reduces bleeding and the need for stitches. Larger procedures may still benefit from sutures; your dentist explains what to expect for your specific case.
Are dental lasers safe?
Yes, when used by trained professionals with appropriate protective equipment. Both the dental team and the patient wear specialized eyewear during laser procedures. Lasers used in dentistry are regulated and have established safety records when applied within their approved indications.
How long does recovery take?
Recovery time depends on the procedure but is typically shorter than recovery from equivalent traditional treatment. Many patients are back to normal activities the same day. Soft-tissue procedures often heal within a week to two weeks; deeper periodontal therapy may take longer for full results to develop.
Are lasers better than drills for fillings?
For most fillings, traditional handpieces remain the standard and are faster and more precise for the actual restoration step. Lasers are useful in specific scenarios — very early decay, decay in certain locations, or procedures where reduced bleeding matters more than speed — but they have not replaced conventional methods for most restorative work.
Will my insurance cover laser treatment?
Coverage varies by plan and by procedure. Many gum and soft-tissue procedures are covered under standard codes regardless of the tool used. We submit a pre-determination to your insurer before treatment so you know what your plan will pay before treatment starts.
