Laser dental fillings

At DENT ESTET, we use Biolase Waterlase laser technology for modern treatments to restore teeth affected by decay. The laser allows the dentist to precisely remove the affected tissue while keeping the healthy structure of the tooth intact — an important step in minimally invasive dentistry.

This revolutionary technology eliminates the need for the classic drill and, in many cases, even anaesthesia. The result is a painless, vibration-free experience with natural tissue healing.

The treatment process begins with the precise identification of tooth decay. Using a laser, the dentist removes the affected tissue layer by layer, without mechanical contact with the tooth. The laser beam vaporises the decayed area, sterilises the cavity and leaves the healthy dentine intact.

After cleaning, the area is prepared for the application of composite material, which integrates perfectly with the tooth structure.
Because the laser creates a natural microtexture of the enamel, the adhesion of the filling material is superior to that achieved by traditional methods.

Studies published in Lasers in Medical Science and the Journal of Conservative Dentistry show that the use of the Er:YAG laser for preparing dental cavities significantly reduces postoperative sensitivity and improves long-term filling retention. 

The durability of a filling depends on the quality of the cavity preparation, the adhesion of the material and the absence of residual bacteria. Lasers excel in all these areas.
Through their sterilising effect, they completely eliminate bacteria from inside the cavity, reducing the risk of caries recurrence.

Furthermore, the laser energy causes a slight change in the crystalline structure of the enamel, which improves the chemical bond between the tooth and the composite material. Biolase studies have shown that laser-made fillings have a retention rate up to 30% higher after 3 years compared to those made by mechanical drilling.

To prevent cavities, dentists recommend regular check-ups and professional cleanings every 6 months. Also, the importance of gum health in dental treatments means that we should not delay consultation when inflammation, redness or bleeding occurs during brushing. 

Although the purpose of both types of fillings is the same — to restore the structure of the tooth affected by decay — the method used to perform the treatment is completely different.

In the case of traditional fillings, the dentist uses a mechanical rotary drill to remove the affected area. The procedure may require local anaesthesia due to the vibrations, noise and pressure exerted on the tooth. In addition, the drill often removes more healthy tissue to ensure access to the decay. Although the results can be good, postoperative tooth sensitivity sometimes occurs, and the contact surface between the composite material and the enamel depends largely on the operating technique.

Laser dental fillings, on the other hand, use a concentrated beam of light (Er:YAG) that acts without direct contact with the tooth. In most cases, anaesthesia is not necessary, as the treatment is completely painless, with no vibrations or disturbing sounds.
The laser instantly sterilises the treated area, eliminating bacteria from deep within, and allows for a much more conservative preparation — only the affected tissue is removed, preserving as much of the natural tooth structure as possible.

The result is a clean, microtextured surface that promotes superior composite adhesion and natural aesthetic integration. In addition, patients report rapid healing and no post-operative sensitivity, completely transforming the experience of dental caries treatment. 

Benefits of painless and minimally invasive laser treatment

• Elimination of drill noise and vibration
• Reduction of dental anxiety, including in children
• Fast treatments without discomfort
• Maximum preservation of healthy tissue
• Complete sterilisation of the cavity

Post-treatment recommendations for maximum durability

• Avoid hard or very cold foods in the first few hours after treatment
• Maintain proper oral hygiene by brushing at least twice a day
• Schedule professional cleanings every 6 months
• Have regular dental X-rays to check the stability of the filling

Why choose laser dental fillings at DENT ESTET

The right doctor and the right technology make the difference between a simple filling and a long-lasting treatment.
At DENT ESTET, laser dental fillings are performed by doctors trained in the use of Biolase technology, as part of internal training programmes coordinated by Dr. Codruța Ciurescu, an internationally recognised expert in laser dentistry.

The laser offers precise control without touching the tooth and a painless experience for the patient — a rare combination of science and comfort.
