Who is a dentist?


Who doesn't want to be able to smile wide with confidence? The key to such a smile is good oral health. Unfortunately, not everyone has good dental health. Tooth decay, cavities, plaque, tartar, and bleeding gums continue to impact millions worldwide. 


So, to avoid dental issues and diseases, appropriate oral hygiene is essential. For this, you need to see a trustworthy dentist regularly. Dentists assess teeth and gum problems and treat specific ailments to ensure optimal oral health.


In other words, dentists diagnose and treat dental and oral health issues. These practitioners usually focus on treating and preventing oral disorders, preserving teeth and tooth structure, and treating diseases that affect the mouth's soft tissues.


Dentistry also covers diagnosing and treating jaw abnormalities, dental alignment difficulties, and oral cavity malformations, such as cleft palate. 


What does a dentist do?


During routine dental checkups, a dental professional will go through the medical history you provided and request tests, such as X-rays, to determine the underlying cause of the problem. They generally also clean the patient's teeth before starting a procedure. Other everyday duties of a dentist include the following:

  • Using X-rays and manual examinations to discover the root cause of teeth, gums, or jaw-related issues.
  • Filling up spaces or gaps after removing deteriorated pulp in a root canal.
  • Taking accurate measurements to fit crowns, dental appliances, and dentures.
  • Extracting non-repairable broken teeth.
  • Replacing teeth with prosthetics.
  • Using sealants and whitening chemicals on stained teeth.
  • Giving dental care guidelines like brushing and flossing, nutrition, and dental equipment like a denture.
  • Straightening misaligned teeth and jawbones


Education and qualification of dentists


Like any other doctor, a candidate must complete an undergraduate chemistry, biology, math, or health program and obtain a bachelor of science degree. Next, they should pass the Dental Admission Test (DAT) to get into dental school. 


Dental training includes the following:

  • Two years of study in biomedical science, followed by clinical practice for two years
  • A Doctor of Dental Surgery (DDS) or Doctor of Dental Medicine (DDM) degree
  • Obtaining a dental license by clearing written and practical exams


Moreover, a dentist must get a license to practice legally in their state. Further, a dentist can get certified by the National Board of Dental Examination. Notably, the American Dental Association (ADA) recognizes 12 dental specialties that require additional professional certification after dental school and advanced education through residencies. 


What are the sub-specialties of dentistry? 


There are several sub-specialties that dentists can choose to pursue. These include the following:

  • Endodontics: These dentists treat problems related to the pulp and root canal system, such as tooth decay and infections.
  • Oral and maxillofacial surgery: This area focuses on surgical treatment of disorders and conditions of the mouth, jaws, and face. Oral and maxillofacial surgeons treat many conditions, including cleft lip and palate, TMJ disorders, and various types of cancer.
  • Orthodontics: This specialty studies the alignment of teeth and jaws. Orthodontists treat patients with crooked teeth or misaligned jaws. They use various methods—braces, retainers, and headgear—to straighten teeth and correct jaw problems.
  • Pediatric dentistry: It is the study of dental care for children. Pediatric dentists specialize in caring for children of all ages, from infancy to adolescence. They focus on preventive care and treating dental problems common to children.
  • Periodontics: These dentists treat problems related to the gums and other supporting parts of the mouth, such as tooth loss and gum disease.
  • Prosthodontics: This subject studies artificial teeth. Prosthodontists treat patients who have lost all or most of their natural teeth. Dentures, bridges, and implants are some methods to restore lost teeth.


What treatments and procedures do dentists perform?


Depending on your specific oral conditions, dentists can provide various treatments and procedures, such as:

  • Fluoride treatment: Fluoride treatment is a crucial preventive measure dentists offer to safeguard against gum disease and tooth decay. They help strengthen the tooth enamel and enhance its resistance to acid attacks from plaque bacteria by administering fluoride, including gels, foams, mouth rinses, supplements, and varnishes. Fluoride promotes remineralization, which can repair early signs of tooth decay and prevent its progression. This straightforward and painless procedure benefits individuals at higher risk of dental caries, including children, patients with orthodontic appliances, or those with dry mouth conditions.
  • Root canal treatment: It is essential in preserving severely infected or damaged teeth, thereby preventing the necessity for tooth extraction. Dentists perform this procedure when the tooth's inner pulp is infected or inflamed due to deep decay, repeated dental procedures, or trauma. During the root canal treatment, the dentist carefully removes the infected pulp, thoroughly cleans the root canal space, and seals it to prevent reinfection.
  • Dental bridges: Dental bridges are a durable and functional solution for individuals missing one or more teeth. These restorations are artificial teeth anchored to adjacent natural teeth or dental implants. Dental bridges help preserve facial structure, stop the remaining teeth from moving, and restore the ability to speak and eat normally. Dental bridges restore the capacity to speak and eat properly, help maintain facial structure, and prevent the shifting of remaining teeth.
  • Veneers: Veneers offer an effective cosmetic solution to address dental imperfections, such as chipped, stained, or misaligned teeth. The dentist transforms teeth instantly when these thin shells of tooth-colored material, made to order, are bonded to the front surface of the teeth. Veneers provide a natural-looking, durable, and long-lasting solution, and the procedure involves minimal tooth preparation. 
  • Crowns: Dental caps, or crowns, are versatile restorations crucial in protecting and strengthening severely decayed or damaged teeth. A crown fully covers the tooth's visible part, effectively restoring its shape, size, and strength. 
  • Pulpotomy: A pulpotomy is a dental procedure primarily performed on children when the pulp in the crown portion of a tooth becomes infected due to extensive decay or trauma. Unlike a complete root canal treatment, in a pulpotomy, the dentist removes only the affected pulp from the crown while leaving the healthy pulp in the root canal intact. This approach helps alleviate pain, prevent further infection, and allow the tooth to function normally until it naturally falls out, promoting the development of a healthy permanent tooth. 


What are some rare tooth disorders?


Some rare oral health issues may arise beyond our control and require professional treatment. These cases are unpredictable, but a dentist can treat them promptly. Here are four rare oral health conditions that everyone should be aware of:


Anodontia

Anodontia is a genetic dental condition in which a person is born without teeth. Dentists diagnose this condition when a baby has not developed teeth by 13 months or when a child has not developed adult teeth by age 10. Dentists use dental X-rays to confirm whether any teeth are hiding beneath the gums. If there are no teeth present, then it is likely anodontia.


Anodontia is a genetic disorder and cannot be reversed or cured. Therefore, treatment is required as missing teeth can affect a person's ability to eat, speak, and even breathe. Popular solutions for this condition include dentures, dental bridges, and dental implants.


Hyperdontia

Hyperdontia is a dental condition where a person has too many teeth. In most cases, it typically involves the appearance of one or two extra teeth. These teeth usually do not erupt, but since they develop in the gum, they can cause overcrowding and delay the appearance of other teeth, leading to crooked eruptions. 


When seeking treatment, your dentist may recommend waiting to see if there are any complications, tooth extraction, or orthodontic treatment. Fortunately, most cases require little to no dental attention!


Talon Cusps

Talon Cusps is a rare condition that affects 0.04 to 8 percent of the population, according to the Oral and Maxillofacial Pathology Journal (OMPJ). It's a conical-like growth at the back of one tooth, which can cause various oral health problems, such as plaque accumulation, gum irritation, and malocclusion. The most common treatment method involves grinding the cusps down unless they are small enough to be ignored. However, if they contain pulp, a root canal may be necessary.


Tooth Gemination

Tooth Germination occurs when two teeth develop from a single bud. This can cause a misaligned bite, overcrowding in the mouth, and tooth decay where the two chambers join, making it look like a single enlarged or disfigured tooth. Your dentist will recommend a specific treatment based on the individual case since this condition varies from person to person. 


Some patients may need sealants and fillings to prevent bacteria buildup, while others require shaping and crowns. Sometimes, it's best to leave it alone and monitor it to determine the best action.


Who should visit a dentist near them?


You should see the dentist every six months for routine checkups to maintain good dental health. Other probable reasons for visiting a dentist include the following:

  1. Preventive care: The primary reason to schedule an appointment with a dentist could be to get preventative care. During routine dental appointments, your dentist will look for gum disease, oral cancer, tooth decay, and other issues. Visit a dentist in your vicinity accepting new patients for regular checkups to help prevent problems from worsening and receive appropriate treatment in time. Furthermore, they clean your teeth and eliminate plaque and tartar buildup, which causes further gum disease and tooth damage.
  2. Discomfort or pain: Experiencing discomfort or pain in your teeth, gums, or jaws is relatively common. If you have been going through something similar, it is time to visit a good dentist. Furthermore, pain in the mouth and neck and swelling in the facial region might indicate a dental condition. Similarly, if you notice bleeding from your gums and have difficulty chewing food, it is prudent to seek dental care.
  3. Oral health maintenance: Visiting a dentist can help you maintain overall dental hygiene. Dentists can also help you improve your dental health if you have undergone a specific medical treatment or are a regular smoker.


What happens during a dental visit?


A trip to the dentist doesn’t have to be intimidating. Dentists as well as hygienists strive to make your visit comfortable with options like TV, movies, or sedation for procedures. Whether it’s your first visit or a routine checkup, it’s essential to maintain good oral health and a brighter smile.


To ease any anxiety, plan for enough time off work or school. Ask about the cleaning and exam duration, especially if it’s been a while since your last visit. Scheduling an end-of-day appointment can help you relax afterward. If you have dental insurance, confirm your dentist is in-network to save costs and check for any out-of-pocket expenses. Arrive early to complete the paperwork and bring your ID and insurance card.


A hygienist will clean your teeth during a routine checkup, removing plaque and tartar with specialized tools. Let them know if you feel discomfort so they can take breaks. After the cleaning is done, the dentist will polish your teeth with a spinning tool and flavored paste, followed by a rinse. They may take X-rays to detect hidden issues. Using a periodontal probe, the dentist will check your teeth and gums for potential problems, discuss findings, and suggest the next steps.


If it’s been a while since your last visit, expect a more detailed cleaning and possibly additional procedures. The dentist may take X-rays to assess your teeth, gums, and bone structure. Cleaning could be slightly uncomfortable with tartar buildup, but removing it is crucial for oral health. Don’t be discouraged by any issues identified during the visit—your dentist will guide you through the solutions for a healthier mouth.
