8 Types of Dentists and Why You May Need to See Them

In the last 40 years, Canadians have started to take their dental health more seriously. Every year, 75% of Canadians visit dental clinics for everything from basic cleanings to oral surgery. The type of dentist a patient will see depends on the person’s oral health.

Every two years, over 86% of Canadians visit their dentist. A general dentist is who most people need to see, but there are multiple dentists that specialize in different areas of dentistry.

General Dentist

Most dental practitioners in Canada practice general dentistry and that includes our team at Lighthouse Dental Centre. There is, roughly, 1 dentist for every 1,600 people in Canada. Rather than focusing on one area of dentistry, general dentists offer a wide array of services, including:

Preventative Care

Oral health starts with preventive services. These services aim to stop decay from occurring through services that include structured care, x-rays, educating patients on proper cleaning techniques, sealants and fitting patients for custom mouth guards if they play sports.


If you have a cavity or other dental problem, timely treatment is required. Decay is removed from the tooth and a filling is placed in the tooth for a cavity. Additional treatments may include replacing missing teeth, crowns, bridgework and even fitting patients for dentures. Some general dentists may also offer implants, root canal therapy or orthodontic services.

Your general dentist can also examine your oral health and identify issues with dental infections, sleep apnea and provide oral conscious sedation for highly anxious patients.

Your bite is important, and if your teeth are misaligned or crooked, an orthodontist is the specialist that you’ll want to see. These professionals can help with a variety of conditions, including but not limited to:

If you’re suffering from poor sleep, headaches or migraines that are a result of your dental or oral health, an orthodontist can help with these issues as well.

An endodontist is a dental specialist that focuses on the tooth’s pulp, or the soft tissue in the teeth. These specialists undergo the same training as a general dentist, but they also take an additional two years of education to become endodontists.

You may be referred to these specialists when your dentist has difficulty diagnosing an issue or treating a more advanced dental issue. If you need a root canal, you may be referred to these specialists, who spend more time studying root canal procedures and techniques than other dentists. These professionals aim to save your teeth rather than remove them.

Oral Surgeon

If major surgical procedures are required, an oral or maxillofacial surgeon is often the dental professional that is best suited for the surgery. These professionals are required to enter a four-year residency at an accredited hospital where they’ll train in:

During their training, they’ll spend a lot of time working alongside an otolaryngologist, or a person specializing in the ears, nose and throat.

Surgeons will also spend some of their training learning about emergency medicine and plastic surgery. A major focus is put on the jaw, face, mouth and the tissues surrounding these areas.

The wealth of knowledge that these surgeons bring to the dental industry often make them the best candidate for serious dental and oral conditions, including but not limited to:

These surgeons can also assist with issues relating to your wisdom teeth, implants, facial trauma and even issues with your temporomandibular joint.

Pediatric Dentist

Infants and children have different concerns with their teeth and tooth development than an adult. Also known as pedodontists, these dental professionals work in a very similar capacity to a general dentist, with the key difference is that they specialize in pediatrics.

Pediatric dentists are trained to deal with a myriad of behavioural issues that occur with infants and children when visiting the dentist. When a teen reaches the age of 18, most pediatric dentists will refer them to a general dentist and will cease treating these patients.

Entering the office of these dentists also provides a different experience. These offices are often designed and decorated to keep young patients occupied. It's common for a pediatric dentist’s office to have play areas, books and games that aim to keep kids occupied while they wait to be called into the office.

An important yet lesser-known area of dentistry is that of an oral pathologist. These professionals are experts in diagnosis and are trained to diagnose any issues that you may have with your:

When a general dentist has issues diagnosing conditions, these professionals can use the x-rays and/or take biopsies of a person’s soft tissue or bone to make a diagnosis. The conditions that they can pinpoint include dental issues, but they also understand that gum disease can be linked to other serious conditions, such as stroke, heart disease and even bowel cancer.

These professionals spend a lot of their learning how to identify cancers in the head or neck.

Complex cases sometimes can best served by visiting a prosthodontist. These dental specialists focus their training on restoring damaged or missing teeth and the oral structures surrounding these areas. If complex oral procedures are needed, it’s not uncommon for a prosthodontist to be called in for the procedure. Some of the many procedures that a prosthodontist may offer are:


Dental disease impacts 3.5 billion people worldwide. A periodontist is responsible for the diagnosis, prevention and treatment of periodontal disease. These professionals will focus on treating the inflammation caused by the disease and also specialize in the placement of dental implants.

A periodontist will undergo three additional years of schooling where they learn how to properly treat and diagnose periodontal disease. Cosmetic procedures are also learned at this time. The treatments they offer depend on the patient’s condition, but may include:

If the disease is advanced, these dentists can offer surgical treatments and are highly trained in dental implant placement.

There are a wide variety of dentists that can help you along your dental journey, from a pediatric dentist that will see you when you’re under 18 to a surgeon that can offer options if you have advanced dental issues. For most people, the first type of dentist they’ll see is a general dentist. From here, their general dentist may then recommend them to one of the many dental specialists listed above.
