The world has become a much better place today, and indeed, the advent of modern technology has played a significant role in making this possible. Modern technology has impacted our world in so many positive ways, and it has made living our lives more manageable and a lot less stressful with all its numerous inventions. If you look around, you indeed find a couple of these tech inventions being used in several sectors to maneuver through complex tasks. One of the most significant inventories that we have seen over the years is laser technology, and this article will highlight how it is used in dentistry.

A laser is a device that emits high-energy light beams through the optical amplification process. The laser typically stands for light amplification by stimulated emission of radiation, and it has been used in many sectors for many assignments since it was first introduced. The use of laser technology has also been adopted in the medical field, and it is used by many medical practitioners, including dentists. More information about this concept will be discussed below. 

What Is Dentistry?

Dentistry, in simple terms, refers to the science of caring for the teeth professionally. It is also known as dental medicine, and it is the branch of medicine that deals with the study, diagnosis, and treatment of oral-related problems. Over the years, dentistry has developed into a crucial branch of medicine, and it can be attributed to the many detriments that accompany bad oral health. According to general dentist Dr. Hashimi, oral health is as essential as the wellness of other parts of the body because a decline in your oral health can cause life-threatening health problems. Hence, oral health and the practice of oral treatments are now held in high significance.

Introduction Of Laser Technology To Dentistry

Laser treatments and the use of lasers in dentistry are some of the newest and most sophisticated additions to dentistry and the entire medical field. Laser technology was introduced in dentistry in the 1960s, and it has since proven to be a crucial addition by many standards. Although many dentists experienced problems with the functionality and usage in the early days, several modifications have been made to improve the usability of these lasers. Dentists were also re-educated on the process and uses of laser technology to perform better. Today, laser technology is utilized correctly by dentists for the treatment of oral diseases without any problem or difficulty.

Uses Of Laser Technology In Dentistry

Laser has become a formidable and versatile tool in dentistry. It is used in almost all the departments for tasks that include oral surgery, preventive dentistry, periodontology, etc. Here are some of the most significant applications of lasers in dentistry, among others.

  1. Oral Surgery: Although laser is not often the first choice for oral surgeries, there is no doubt that it is a suitable alternative to conventional oral surgery methods. The standard lasers used for this purpose are the Co2 and diode lasers due to the accuracy and precision they cut and drill while performing maxillofacial surgeries.

  2. Preventive Dentistry: Laser technology is used to prevent oral diseases like cavities and other infections, and here's how. The enamel is the protective layer of the teeth, and it is often affected by phosphoric acid, which can cause total damage to the teeth in severe circumstances. However, laser irradiation of the enamel helps keep the phosphorus at a moderate level and improves the teeth' resistance to cavities.

  3. Restorative dentistry: Laser technology was first introduced to dentistry for this purpose, and it has proved to be excellent for the task. The argon laser produces a blue light beam, and it is used for the treatment and restoration of semi-decayed teeth and gums. Using a laser to restore the teeth to normalcy is called laser polymerization.

  4. Cutting Hard Tissues: At first, this task proved quite tricky because the laser was always too hot and caused damages to the pulp. However, revised laser versions have proved to be perfect for cutting hard tissues around the teeth without causing any damage to the oral system.

Advantages Of Laser Technology In Dentistry

- Lasers are less painful than traditional drills, thereby minimizing the need for anesthesia.

- Reduces post-surgical bleeding and swollen gums.

- Requires less time to heal.

- Keeps the chances of infections at minimal.

- Lasers are precise and promote accurate operations.


Laser technology is a brilliant addition to dentistry, and there is no doubt that this technology has come to stay. Lasers are versatile tools, and the fact that it is safe and reliable further increases their appeal, especially in the dental industry.
