Laser Teeth Whitening

White, healthy teeth are important not only for a beautiful smile but also for boosting self-confidence. However, drinking beverages such as coffee, tea, or red wine, or smoking, can cause stains on your teeth. Fortunately, modern dentistry offers an effective and quick solution to this problem in the form of laser teeth whitening. Compared to traditional methods, this procedure is performed in a shorter timeframe in a clinical environment under the supervision of a specialist dentist and produces permanent, visible results. So, what is laser teeth whitening, what are its advantages, and is it suitable for everyone? Let's take a closer look at this method.

What are teeth whitening techniques and methods?

Teeth whitening techniques:

Mechanical Cleaning:

Mechanical cleaning is achieved by mechanically agitating the tooth surface using gels, pastes, or liquids (including toothpastes) to remove stains from the stained tooth surface by abrasive erosion. This routine polishing removes surface stains such as coffee, cigarettes, and red wine but does not change the color of the teeth.

Chemical Whitening:

Chemical whitening is done by leaving gels, pastes, or liquids in contact with the stained tooth surface for a certain period of time, which allows tooth staining to be removed by a chemical process. In this method, whitening is achieved by chemical degradation of chromogens in the tooth enamel. Typically, whitening gels containing hydrogen peroxide or compounds that release hydrogen peroxide in water are used. Gels may also contain thickening, stabilizing, and neutralizing agents.

Laser-Assisted Teeth Whitening:

Lasers aim to increase the effectiveness of whitening agents and accelerate the release of free ions to the tooth surface. There are different types of lasers used in teeth whitening.

Teeth whitening methods:

  Professional (in clinic) teeth whitening:

Laser teeth whitening:

It is performed using a special gel and laser beam under the control of a dentist. It gives significant results in a single session.

Bleaching whitening:

Whitening gels activated by LED or plasma light are used. Effective results are obtained in 30-60 minute sessions.

Home teeth whitening methods:

Dentist-controlled transparent trays:

Whitening is achieved in a few weeks with individually prepared trays and special gels.

Whitening strips:

Thin strips adhered to the tooth surface remove light stains by containing hydrogen peroxide.

Whitening toothpastes:

Contain abrasive particles or mild whiteners, but have a limited effect.

Natural and herbal methods:

• A mixture of baking soda and lemon: Although it provides short-term brightness, it can damage tooth enamel and should be used with caution.
• Oil pulling with coconut oil: It supports dental health with its antimicrobial effect, but its whitening effect is weak.

What is the principle of laser teeth whitening?

Laser teeth whitening is based on the principle that a whitening gel containing hydrogen peroxide or carbamide peroxide is activated by laser light to remove stains and discoloration of tooth enamel. The process works as follows:

Gel application:

 The dentist applies a high concentration of whitening gel to the tooth surface. This gel contains chemicals with oxidizing properties.

Laser activation:

Laser light with a special wavelength activates the whitening agents in the gel. The laser accelerates the gel to release oxygen molecules. These molecules chemically break down organic stains (coffee, tea, cigarettes, etc.) on the enamel.

Stain removal:

 The oxygen molecules oxidize the discoloring molecules (chromogens) in the enamel, making them colorless. This reveals the natural whiteness of the tooth.

Fast and controlled effect:

The laser accelerates the action of the gel and targets deeper stains. The procedure usually takes 30-60 minutes and is applied in a controlled manner so that the tooth enamel is not damaged.

Which types of lasers are used in laser teeth whitening?

In laser teeth whitening, low-intensity laser types that do not damage soft tissues are generally used. The most commonly used laser types are as follows:

Diode lasers:

It is the most preferred laser type for teeth whitening. It effectively activates the whitening gel containing hydrogen peroxide or carbamide peroxide. Safe, precise, and fast results. Compact devices, low heat generation, and minimal effect on gum tissues.

Argon lasers:

Used to activate the whitening gel and are particularly effective on superficial stains. It works with the blue-green light spectrum. It provides precise application and rapid activation but is less common than diode lasers.

Nd:YAG lasers:

Less commonly used Provides deep penetration and is effective in gel activation. It works without damaging the tooth enamel.

KTP Lasers (Potassium Titanium Phosphate):

It works in the green light spectrum and is used to activate the whitening gel. It offers high sensitivity, but is used less frequently than other lasers.

Step-by-step laser teeth whitening procedure

The laser-assisted teeth whitening procedure consists of certain steps, from the preparatory phase to the final steps. These steps are:

Preparatory phase:

Determining the tooth color:

The initial color of the patient's teeth is measured and recorded using the Vita color scale. A photograph of the "before" color can also be taken to help the patient better visualize the results.

Tooth cleaning:

The tooth surfaces are cleaned with a glycerine-free pumice. This removes dental plaque and superficial stains, taking care not to abrade soft tissue.

Lip protection and retractor application:

Vaseline is applied to the patient's lips and cheek retractors are placed. Cotton rolls can be used for additional protection and comfort. Vaseline application to the mucosa provides additional comfort in areas not protected by the liquid barrier.

Liquid barrier application (liquid dam):

• Teeth and gum tissue are rinsed and air-dried.
• The flow of the liquid barrier is started by pouring a small amount onto a mixing pad.
• Liquid barrier is applied to the gums in a strip approximately 2 mm wide and 1-1.5 mm thick. In the gaps, the liquid barrier is squeezed through the opening to completely fill the gap. Ensure that the material extends at least half a millimeter above the enamel and that the exposed root surfaces are covered.
• The liquid barrier is cured in sections with a standard light for 5-10 seconds per arch.

Mixing the bleaching gel:

• Remove the caps from the activator and base gel syringes. The two syringes are twisted together and connected until fully squeezed.
• Holding the pistons of both syringes firmly, the contents of the lavender syringe are pressed into the transparent syringe. This process is repeated 25 times, making sure that the gel is consistent throughout the syringe; continue mixing if necessary.
• Transferring the gel: The mixed gel is pushed into the gel base reservoir, then the syringes are separated.
• A brush applicator tip is attached.

Gel Application:

• The upper and lower arches are divided into four treatment zones (e.g., Q1 upper right, Q2 upper left, Q3 lower left, Q4 lower right).
• Teeth are dried with gauze or a cotton roll.
• A thin layer (approx. 1 mm) of the mixed LaserWhite gel is applied evenly to all four areas. Only half of the gel is used for this application; the remaining half is saved for the second application. If desired, half of the gel can be poured into a mixing bowl and applied with a small brush.
• Make sure that the gel does not come into contact with the patient's gums, tongue, or lips. The patient is checked for sensitivity or discomfort.

Laser Application:

First application:

• Ensure that everyone in the room is wearing appropriate eye protection and press the "Ready" button on the EPIC device.
• The whitening handpiece with the disposable transparent cap is placed approximately 1 mm away from Q1 without touching the gel.
• The laser is activated by pressing the foot pedal, and the handpiece is held in place for 200 J of laser energy (approx. 30 seconds). These steps are repeated for Q2, Q3 and Q4.
• This is repeated once more for all quadrants (each quadrant thus receives two doses of laser energy).
• The gel is removed using a surgical aspiration tip. If necessary, it is gently washed with air and water spray to remove the remaining gel.

Second application:

• The used brush applicator tip is replaced with a new tip, and the second half of the remaining LaserWhite gel is reapplied by repeating the above steps.
• The laser application steps are repeated (each quadrant receives a total of four doses of laser energy).
• After the last laser cycle, the gel is allowed to remain on the teeth for five minutes and then removed.

Final Steps:

• The teeth are thoroughly rinsed with water from the syringe.
• The liquid barrier is carefully lifted and removed by sliding the tip of an excavator or forceps between the gum and the barrier.
• The remaining liquid barrier is removed from the interfaces using an excavator or dental floss and rinsed again.
• A final polishing is performed with a fine-grained paste to give the teeth shine and luster.
• A damp cotton gauze pad is placed over the gums and teeth and left for a few minutes to rehydrate the tissues and enamel.
• The final shade is measured and recorded using the Vita Shade Guide Gloss Scale. The initial and final colours are compared with the patient.

Who are suitable candidates for laser teeth whitening, and who are not?

Although laser teeth whitening is an effective aesthetic dental treatment, it may not be suitable for everyone. The determination of suitable candidates is made by the dentist's examination.

          Suitable candidates for laser teeth whitening:

Those with healthy teeth and gums:

 People without tooth decay, gum disease (gingivitis, periodontitis), or enamel erosion are ideal. Oral health problems should be treated before the procedure. Those with External Stain Problems: Laser whitening is very effective for people with superficial stains (extrinsic stains) caused by external factors such as coffee, tea, red wine, and smoking. Yellowish or brown-toned teeth usually give good results.

Adults (18 years and over):

 Suitable for adults with complete tooth development. Generally not recommended for children and teenagers (under 18 years of age) as the enamel is still developing.

Those with realistic expectations:

Suitable for those who want to lighten their natural tooth color by a few shades. However, it may have limited effect on very dark (grey or blue-toned) intrinsic stains (intrinsic stains).

  People with no sensitivity problems or mild sensitivity:

The procedure is more easily tolerated in people with minimal tooth sensitivity. In case of severe sensitivity, the dentist may take additional measures.

For whom is laser teeth whitening not suitable?

• Pregnant and Breastfeeding Women
• Those with excessive wear or sensitivity of tooth enamel
• Those with gum disease (periodontitis) or recession
• Those with fillings, veneers, or porcelain crowns
• Those with deep internal discoloration, such as tetracycline stains or fluorosis
• Individuals under the age of 18
• Those with asthma or hypersensitivity to chemicals

Are there cases where whitening is not effective?

Although laser-assisted teeth whitening is usually successful, in some cases it may not have the expected effect:

• Teeth with exposed roots.
• Teeth with 'white' fillings.
• Teeth with crowns or veneers.
• Root canal-treated teeth.
• Unhealthy teeth

What are the benefits and advantages of laser teeth whitening?

Laser teeth whitening is a popular method in cosmetic dentistry and offers many benefits and advantages.

Fast and effective results:

• Laser teeth whitening usually lightens teeth by several shades in a single session (30-60 minutes), providing fast and noticeable results.
• It effectively removes external stains such as coffee, tea, and smoking.

Long-lasting effect:

With proper care and lifestyle changes (avoiding stain-causing foods), results can last for 1-2 years or longer.

Minimally invasive:

It works without damaging the tooth enamel, protects the tooth structure, and does not require a surgical procedure.

Increased self-confidence:

A whiter and brighter smile provides aesthetic satisfaction and increases self-confidence.

Professional control:

The procedure is safe and controlled because it is performed by a dentist. Gum and enamel health is protected.

Precision of laser technology:

The laser activates the whitening gel, providing deeper and more even results. A more homogenous whiteness is achieved compared to other methods.

Short-term process:

While home kits take weeks, laser whitening is completed in a single session, which saves time.

Customizable:

The dentist can adjust the gel concentration and laser application according to the patient's tooth color and sensitivity.

Low risk of sensitivity:

Modern laser systems and preventive measures (gum barrier, fluoride application) minimize sensitivity.

What are the risks and disadvantages of laser teeth whitening?

Although laser teeth whitening is generally a safe procedure, there are some risks and disadvantages.

Tooth sensitivity:

 Temporary sensitivity of the teeth after the procedure (especially to hot/cold foods) is a common side effect. This usually subsides within 24-48 hours but may be more uncomfortable for people with sensitive teeth.

Gum irritation:

 Mild irritation or burning sensation may occur if the whitening gel comes into contact with the gums. Although a gum barrier is used in professional applications, small leaks may create this risk.

Potential for enamel damage:

Although rare, when applied incorrectly or repeated too often, whitening gel may cause microcracks or weakening of the enamel. This is usually the result of inappropriate concentration or frequency of application.

Allergic reactions:

The risk of allergic reactions to gel containing hydrogen peroxide or carbamide peroxide is low, but some people may experience sensitivity or oral irritation.

Irregular whitening:

Existing fillings, veneers, or dentures on teeth are not affected by whitening. This can lead to a color mismatch between teeth.

High cost:

Laser teeth whitening is more expensive compared to at-home whitening kits or over-the-counter products. Since it is a professional procedure, the cost may vary depending on the clinic and region.

Temporary results:

The results are not permanent; teeth may re-yellow if exposed to staining agents such as coffee, tea, cigarettes, etc. Additional sessions may be required for maintenance.

What should the care be after laser teeth whitening?

Aftercare after laser teeth whitening is important to increase the effectiveness of the procedure, ensure the permanence of the results, and minimize possible side effects (sensitivity, irritation). The first 48 hours are the most critical period because the pores of the tooth enamel are open and more prone to staining.

Depending on the natural color of your teeth and your lifestyle, the whitening effect can last 1-2 years. Regular care prolongs this period.

First 24-48 hours: follow a "white diet."

• Avoid staining foods: Avoid foods that can stain teeth, such as coffee, tea, red wine, cola, colored sauces (tomato, soy), acidic drinks, and colored fruit juices (pomegranate, cherry).
• Recommended foods: Eat colorless and acid-free foods such as yoghurt, milk, white meat (chicken, turkey), rice, potatoes, bananas, apples (without skin), and cauliflower.
• Avoid smoking and tobacco: Nicotine can create new stains on teeth and reduce the whitening effect.

Pay attention to oral hygiene:

• Gentle brushing: Teeth may be sensitive after the procedure. Brush gently with a soft-bristled toothbrush and a low-abrasive toothpaste. Avoid brushing too hard in the first 24 hours.
• Floss and mouthwash: Use dental floss to clean between teeth. Choose a mouthwash that does not contain alcohol and is suitable for sensitive teeth.
• Fluoride products: If your dentist recommends it, you can use toothpaste or gel containing fluoride to reduce sensitivity.

Manage sensitivity:

• Avoid cold/hot foods: Tooth sensitivity can be common after a procedure. Avoid excessively hot or cold foods/drinks for the first few days.
• Sensitivity-reducing products: Your dentist may recommend desensitizing toothpaste or gel to reduce sensitivity.
• Painkillers (if necessary): If you experience mild discomfort, you can use a painkiller such as ibuprofen in consultation with your dentist.

Moisturizing and water consumption:

• Drink plenty of water; this removes debris from the mouth and reduces the risk of irritation from gel residues.
• Drinking through a straw minimizes contact with teeth and maintains the whitening effect.

Long-term care:

• Regular tooth brushing and checkups: Brushing twice a day and regular dental checkups maintain whitening results.
• Reduce staining habits: Limit habits such as smoking and excessive coffee/tea consumption.
• Touch sessions: Maintenance sessions at intervals recommended by your dentist (usually every 6-12 months) or low-dose whitening kits can be used at home to maintain the whitening effect.

Follow the dentist's recommendations:

Every individual's dentition is different; be sure to follow your dentist's specific instructions.

If you notice abnormal sensitivity, pain, or gum irritation after the procedure, contact your dentist immediately.

Laser teeth whitening price:

Laser teeth whitening prices vary depending on the region of the clinic and the materials used. You can contact MagicTouch Dental Clinic to get current prices.
