The evolution of lasers in Dentistry

The use of lasers in dentistry dates back to the mid-1960s when researchers first experimented with laser beams on tooth structure. However, it was not until the 1990s that lasers were approved by the Food and Drug Administration (FDA) for dental use. Since then, there has been significant progress in laser technology specifically designed for dental procedures.

Types of dental lasers

There are different types of lasers used in dentistry today depending on their wavelength and usage. The two most commonly used ones are hard tissue and soft tissue lasers.

Hard tissue lasers

These types of lasers emit light at specific wavelengths that can be absorbed by mineralized tissues like enamel or bone without affecting other tissues’ surrounding areas. They are commonly used for cavity detection, removal of tooth decay or old fillings, and preparing teeth for bonding or receiving crowns.

Soft tissue lasers

These types of lasers emit light at wavelengths that are absorbed by the water in soft tissues, making them ideal for cutting and removing soft tissue without causing any damage to the underlying structures. They are commonly used for gum disease treatment, reshaping gums, and removing excess tissue.

How lasers are transforming dentistry

Minimally invasive procedures

One of the main advantages of using lasers in dentistry is that they offer minimally invasive treatments compared to traditional methods. For example, when treating cavities, a laser can target only the affected area without damaging healthy tooth structure. This leads to less pain, bleeding, and swelling for the patient and faster healing times.

Precision

The use of lasers in dentistry allows for precise targeting of specific areas without affecting surrounding tissues. This makes it possible to remove decay or diseased tissue while preserving healthy structures, leading to improved outcomes and reduced risk of complications.

Common procedures that utilize laser technology

Laser technology has revolutionized the field of dentistry, providing a more efficient and precise alternative to traditional dental procedures. The use of lasers in dentistry is becoming increasingly common, with many dental professionals incorporating this technology into their practice.

In this section, we will discuss some of the most common procedures that utilize laser technology and how they have transformed the way dental treatments are performed.

1. Laser cavity detection

One of the most significant advancements in dentistry made possible by lasers is the early detection of cavities. Traditional cavity detection methods involve X-rays or manually probing each tooth for signs of decay. This process can be time-consuming and uncomfortable for patients.

With laser cavity detection, a low-powered laser light is used to scan the teeth for any signs of decay. As the light passes through healthy teeth, it reflects evenly, but if there is a cavity present, it scatters differently, indicating its presence. This method allows for faster and more accurate identification of cavities without exposing patients to radiation.

2. Gum disease treatment

Gum disease is a prevalent oral health issue that can lead to serious complications if left untreated. Traditionally, treating gum disease involves invasive procedures such as surgery or deep cleaning with sharp instruments that could cause discomfort and bleeding.

With laser technology, dentists can now perform minimally invasive procedures to treat gum disease effectively. The focused energy from lasers can remove diseased tissue and bacteria while sealing blood vessels and nerve endings at the same time, promoting quicker healing and  reducing discomfort for patients.

3. Teeth whitening

Laser technology has also been incorporated into teeth whitening procedures, providing faster and more effective results than traditional methods. With laser whitening, a bleach solution is applied to the teeth, and then a laser is used to activate the whitening agent, speeding up the process.

The energy from the laser helps to break down stains on the surface of the teeth, leaving them noticeably whiter in just one session. This method produces less sensitivity and can achieve more significant results than over-the-counter whitening kits.

4. Biopsies

In some cases, dentists may need to perform a biopsy to diagnose certain oral health conditions such as oral cancer or lesions. Traditional biopsies involve surgically removing a piece of tissue for examination under a microscope.

With laser technology, dentists can now perform non-invasive biopsies using high-energy lasers that remove small pieces of tissue without causing any bleeding or discomfort. This method allows for quicker healing times and more precise results.

5. Tooth desensitization

Sensitive teeth can be caused by various factors such as tooth decay, receding gums, or worn enamel. Traditional methods of treating sensitive teeth involve applying topical products or using special toothpaste to help reduce sensitivity.

With laser technology, dentists can now perform tooth desensitization procedures by sealing the tubules responsible for transmitting pain signals to the nerves. This procedure provides long-term relief for patients and can be completed in just one session.
