What is the difference between an orthodontist and a dentist?

December 25th, 2022

Orthodontists and general dentists are both dental professionals who work to maintain and improve the oral health of their patients, but they have different areas of focus and expertise.

Orthodontists are dental specialists who focus on the diagnosis, prevention, and treatment of dental and facial irregularities. This includes correcting misaligned teeth, malocclusions (improper bites), and other issues with the teeth, jaws, and bite. Orthodontists use a variety of techniques to straighten teeth, including braces, Invisalign, and other appliances. They often work closely with patients over a period of several months or years to achieve the desired results.

General dentists, on the other hand, provide a wide range of general dental care services to patients of all ages. This includes preventive care, such as cleanings and fluoride treatments, as well as restorative procedures like fillings, crowns, and bridges. They may also perform cosmetic procedures, such as teeth whitening or veneers, to improve the appearance of their patients' smiles.

One key difference between orthodontists and general dentists is the amount of training and education they receive. Orthodontists must complete a two- to three-year residency program in orthodontics after earning their orthodontic specialty certificate. This additional training allows them to gain expertise in the field of orthodontics and to specialize in the treatment of dental and facial abnormalities. General dentists, on the other hand, do not receive this specialized training and are more focused on providing a broad range of general dental care services.

Another difference between the two is the type of treatment they offer. Orthodontists primarily focus on straightening teeth and correcting misalignment, while general dentists offer a wider range of services including preventive care, restorative care, and cosmetic procedures.

Orthodontists are dental specialists trained to correct overbites, underbites, crossbites, deep bites, and open bites. Not only are they experts at using clear aligners when appropriate, but they also understand how and when to use expanders, functional appliances, braces, extractions, and surgery when necessary. You only have one set of teeth and you want a specialist handling your treatment.

It's important to note that both orthodontists and general dentists play important roles in maintaining the oral health of their patients. If you have concerns about the alignment of your teeth or bite, it's a good idea to visit an orthodontist for a consultation. If you have general dental health concerns or are in need of preventive care, a general dentist can help.

How do braces actually move my teeth?

December 25th, 2022

Orthodontics is a branch of dentistry that focuses on the alignment and straightening of teeth, as well as correcting bite problems. One of the most common treatments in orthodontics is the use of braces, which are devices used to apply constant, gentle pressure to the teeth in order to move them into the desired position.

But how exactly do braces work, and what is the biology behind orthodontic-facilitated tooth movement?

When teeth are subjected to constant pressure, they will naturally try to move in the direction of that pressure. This is because the teeth are held in place by a group of specialized cells called periodontal ligament cells, which are found in the periodontal ligament (PDL) that surrounds the tooth. These cells are responsible for anchoring the tooth to the jawbone, as well as allowing for movement of the tooth when subjected to force.

When a tooth is subjected to pressure from a brace, the PDL cells on the side of the tooth facing the direction of the pressure will become stretched and elongated. At the same time, the PDL cells on the opposite side of the tooth will become compressed and shortened. This creates tension in the PDL, which prompts the cells to divide and multiply in order to maintain their ability to hold the tooth in place.

As the cells divide and multiply, the tooth is slowly moved in the opposite direction of the pressure. This process is called orthodontic facilitated tooth movement. It occurs in small increments over a period of time, with the rate of movement determined by the amount of force applied and the duration of treatment.

The biology behind orthodontic facilitated tooth movement is a complex and fascinating process that involves the interaction of various cells and tissues in the mouth. By understanding how braces work and the role that the PDL plays in tooth movement, orthodontists are able to effectively straighten and align teeth to improve the overall health and appearance of their patients' smiles.
