Laser dentistry is ideal for preparing teeth for veneers that achieve a precise, natural look.
Laser dentistry has well and truly landed in Australia. While it first appeared in forward-thinking dental practices during the 1990s, laser dentistry is now in relatively common use in daily practice across the country.
It is widely heralded for its superior precision and minimal invasiveness that typically leads to less patient discomfort, faster healing times, and better aesthetic results. Laser dentistry also gives dentists the opportunity to reduce chair time with more efficient workflows.
Laser dentistry can be used for a wide range of procedures, but common applications include:
- Soft tissue surgeries: Lasers are highly effective in reshaping the gum line, performing frenectomies, and treating periodontal disease. Lasers typically reduce trauma to soft tissues to minimise bleeding, reduce patient discomfort, and accelerate healing.
- Hard tissue procedures: Lasers reduce the need for traditional drilling by removing decayed material from teeth, preparing enamel for fillings, and reshaping teeth for crowns or veneers.
- Teeth whitening: Laser technology is widely used in the teeth whitening process to activate bleaching agents contained in whitening gels. This can help to achieve brighter teeth in a shorter time frame than conventional methods.
- Root canal treatments: Lasers can be used to enhance root canal therapy by disinfecting and shaping the inner canals more effectively to reduce the likelihood of post-treatment complications, and ensure the longevity and health of the treated tooth.
- Veneers: Lasers play a crucial role in the application of veneers. They can be used to reshape the gum line and prepare the tooth surface for bonding to ensure a precise fit.
Laser dentistry and veneers: A case study
Traditionally, the application of veneers involved reshaping teeth with dental drills, which could be uncomfortable for patients and require multiple appointments. Laser dentistry, however, has gone a long way to making veneer treatments far more patient-friendly with minimal bleeding, faster healing times, and fewer appointments typically required.
Many dental practitioners use lasers to create an optimal bonding surface that ensures a stronger attachment of the veneers, which enhances their longevity and appearance.
For patients, reduced discomfort and faster recovery times may make laser-assisted veneer procedures far more appealing than traditional drill-based alternatives, especially for those with dental anxiety.
For dentists, the use of lasers in veneer placement improves the efficiency and accuracy of the procedure. The ability to perform precise reshaping and bonding in fewer steps reduces the time required for each treatment. This allows dentists to treat more patients without compromising on the quality of care.
Advanced laser dentistry techniques for veneers
Mastering advanced laser techniques for veneer procedures can greatly enhance the precision, efficiency, and comfort of treatments. By utilising laser technology, dentists can achieve superior aesthetic results, improve patient recovery, reduce chair time, and streamline the overall process of veneer application.
Many of these techniques also apply to crown and bridge restorations, which makes laser dentistry a versatile skill set dentists can apply to a range of treatment modalities.
1. Gingival recontouring for optimal veneer fit
- Why it matters: Proper gum contouring is essential for the aesthetic success of veneers. When gum margins are uneven or excessive tissue covers part of the tooth, it can detract from the final appearance of veneers. Gingival recontouring with lasers helps establish the ideal framework for veneers.
- Technique explanation: Using a diode or erbium laser, you can sculpt the gum line with high precision. The laser’s ability to ablate soft tissue without significant bleeding makes it easier to see the gingival contours in real-time. The laser seals blood vessels as it cuts to improve your visibility, and reduce postoperative inflammation and patient discomfort.
- Practical tip: Start by marking the desired gingival margin line with a periodontal probe, then use the laser to carefully ablate tissue along that line. Always maintain a controlled and consistent pass to ensure even contours. Use short laser pulses to minimise thermal damage to the adjacent tissues.
2. Micro-etching with lasers for bonding
- Why it matters: The success of veneer bonding hinges on a proper surface texture that allows bonding agents to penetrate the enamel. Traditional methods like acid etching can cause over-etching or uneven surfaces. Lasers allow you to create a microscopically roughened enamel surface with precise control. This technique also applies to bonding crowns and creating a rough surface to assist cases where cementing is required.
- Technique explanation: When using erbium lasers for micro-etching, the laser removes a very fine layer of the enamel. The laser’s wavelength interacts with water molecules in the enamel for precise ablation without causing excessive heat or damage. The enamel surface becomes evenly textured, which helps adhesives bond more securely and improves the longevity of the veneers.
- Practical tip: Set the erbium laser to a low power setting, and use short pulses to prevent excessive removal of enamel. Conduct a final visual inspection under magnification to ensure an even texture before applying the bonding agent.
3. Laser frenectomy before veneer application
- Why it matters: A prominent frenulum can interfere with proper veneer placement and gum aesthetics. A laser frenectomy can be performed painlessly and efficiently to ensure better veneer positioning and symmetry.
- Technique explanation: A diode laser is commonly used for frenectomy procedures. The laser quickly severs the frenulum without the need for sutures, and it simultaneously cauterises the area to minimise post-operative discomfort and swelling. This procedure is often necessary when the frenulum pulls on the gum tissue and could potentially cause recession after veneers are placed.
- Practical tip: Aim the laser at the narrowest part of the frenulum for precise cutting, and move the laser in a continuous motion to avoid excessive heat buildup in the tissue. Perform a gentle stretch of the upper lip afterward to ensure the tissue’s mobility.
4. Precise gingival troughing for impressions
- Why it matters: Getting a perfect impression for veneers is essential for the fit and aesthetic appearance. Gingival troughing with a laser can be used instead of retraction cords to provide better visibility and cleaner margins during impression-taking.
- Technique explanation: Use the laser to remove minimal amounts of gingival tissue around the margins of the prepared teeth to create a well-defined trough. The procedure leaves a blood-free environment ideal for digital or physical impressions. Troughing with lasers is particularly useful for patients with inflamed or sensitive gums, where traditional methods could cause more discomfort or bleeding.
- Practical tip: A diode laser is ideal for soft tissue troughing. Ensure that the laser is set to a low power setting to avoid excessive tissue removal, and always move the laser in short, controlled passes. Make sure the gingival tissue is fully retracted before taking the final impression.
5. Laser-assisted osseous reduction
- Why it matters: In some cases, especially when significant gum recession or bone overgrowth is present, the bone may need to be reshaped for the veneers to sit properly. Traditional osseous surgery can be invasive, but lasers allow for minimally invasive bone reshaping. Laser-assisted osseous reduction can also be used to reshape or reduce bone tissue in preparation for dental implants.
- Technique explanation: An erbium laser allows for controlled bone removal with less thermal damage than traditional drills. This is particularly useful when creating a biological width for the veneers to prevent gum irritation and future complications. The laser ablation of bone also doesn’t require the intense water cooling needed in mechanical bone cutting.
- Practical tip: Ensure that the laser is set to a bone-specific wavelength, and adjust the power settings depending on the density of the bone. Work slowly and continuously monitor the bone level to avoid excessive removal.
6. Managing post-operative sensitivity with lasers
- Why it matters: Patients sometimes experience post-operative sensitivity following veneer placement, especially if enamel has been removed. Lasers can help desensitise the tooth and promote faster healing.
- Technique explanation: Use a low-power diode laser to apply gentle heat to the affected areas. This stimulates cellular activity and helps seal dentinal tubules. Additionally, lasers can be used to encourage blood flow in the surrounding tissue to promote faster healing and reduce inflammation.
- Practical tip: Use low-level laser therapy (LLLT) for 30 to 60 seconds over each sensitive area, and move the laser continuously to avoid heat buildup.
