Laser (Light Amplification by Stimulated Emission of Radiation – light reinforcement is done with a focused beam of radiation) is a strong light and has a high intensity that can provide treatment and more accurate results in a wide range of medical action. Unlike ordinary light composed of multiple wavelengths that overlap, the laser beam provides a more centralized and aligned. Treatment with laser teeth are all sorts of measures for dental problems using laser energy. Although its use in this field has been a long time, there is still controversy in the use of lasers in dentistry, especially when it comes to the safety and effectiveness in the use of laser light to some dental care measures by below:

• Root Dental Care – Care tooth root is one type of action dentistry which showed positive results when done with a laser. Tooth root treatment is a thorough dental cleaning action on the tooth root, especially in the areas found their cavities.

• The diagnosis of caries – caries is tooth decay. Certain types of lasers can be used as a fluorescence light, which makes the process of detecting problems in the enamel becomes more effective and efficient.

• Hard Tissue Ablation – lasers can also be used to measure cutting or removal of tooth enamel and the inside of the teeth.

• Endodontics – Endodontics is root canal treatment for swelling or infection.
