Common Dental Terms

We've put together this handy reference guide of terms you might hear when speaking with your dentist or support staff.

Please don't hesitate to ask your dental care provider for clarification of any terms. We're here to help make your experience as pleasant as possible!

Abrasion: Loss of tooth structure caused by a hard toothbrush, poor brushing technique or bruxism (grinding or clenching the teeth).

Bonding: Adhesive dental restoration technique. A tooth-colored composite resin to repair and/or change the color or shape of a tooth.

Bone Resorption: Decrease in bone supporting the roots of teeth, which is a common result of periodontal (gum disease).

Braces: Devices used by orthodontists to gradually reposition teeth to a more favorable alignment.

Bridge:

Bridges resemble natural teeth, and are designed to take the place of areas where there are gaps between teeth. bridge is a stationary dental prosthesis (appliance) fixed to teeth adjacent to a space. It replaces one or more missing teeth, cemented or bonded, to supporting teeth or implants adjacent to the space. If you need a crown or bridge you’ll be expertly fitted by one of our specialists.  No more worrying that the crown or bridge is going to be ill fitting or look unnatural.

The world of dentistry is growing by leaps and bounds, and soon crowns and bridges will be much more affordable for anyone who would like to have them. While some are covered by some types of insurance (wholly or partly), it depends on the company and the reason for the crown and/or bridge. Those put in place solely for cosmetic purposes may not always be covered, or may only be covered after a specific deductible has been met.  Let us help keep your smile flawless.

Bruxism: Grinding or gnashing of the teeth, most commonly while the patient is asleep.

Calcium: Chemical element needed for healthy teeth, bones and nerves.

Cleaning:

Cleaning is a word that has been misused to identify a procedure that is routinely completed on a patient that is free of disease or has a healthy mouth. The appropriate word for this type of “cleaning” is prophylaxis, which is the specific type of cleaning that most insurance companies cover two times per year. There are several different types of “cleanings” that are recommended by the dentist and hygienist depending on the patient's oral health. To determine which type of “cleaning” is prescribed for you, please ask your dental professional.

Composite Resin: Material composed of plastic with small glass or ceramic particles that is usually cured with filtered light or chemical catalyst.

Cosmetic Dentistry: If you’re interested in correcting minor flaws in your smile we can help. Your teeth may be stained from years of coffee or wine drinking that has dulled your smile.

Crossbite: Reverse biting relationship of upper and lower teeth also known as underbite, as in Class III malocclusuion (prognathic jaw).

Crown:

Dental crowns and bridges are very popular among people of all ages, of either sex, and regardless of ethnic diversity. These are mostly cosmetic forms of treatment, covering unsightly teeth or replacing missing teeth for most. Because they look (and feel) more like real teeth, they are most commonly sought for those who have crooked, broken, cracked, or chipped teeth as a way of improving overall mouth health and achieving a beautiful smile.   Tooth crowns are placed over existing teeth, and are typically a way to cover teeth that have metal fillings or misshapen teeth. Because they go on over what is already there, there is no need for the tooth to be pulled. Teeth crowns are an excellent way to improve a smile quickly and efficiently, and more permanent crowns normally replace temporary ones in less than a week.

If you need a crown or bridge you’ll be expertly fitted by one of our specialists.  No more worrying that the crown or bridge is going to be ill fitting or look unnatural.  Let us help keep your smile flawless.

Orthodontics:

Orthodontics is somewhat similar to prosthodontics, since both use artificial means of replacing, repairing, or correcting the smile and jaw. However, where prosthodontics focus on bridges, dentures, and implants, orthodontics normally involves dental braces and similar features in order to do the job. Whether traditional metal braces or innovative invisible braces are used, the effect is normally a straight smile in a relatively short time.  

Dental braces are normally metal or metallic braces made from an alloy that hold teeth in a certain position and then are gradually adjusted to straighten crooked teeth, close gaps between teeth, or push teeth apart in some cases. Invisible braces are tools used to straighten teeth (normally minor repairs), but are nearly invisible to other people. Tools such as plates, retainers, and similar dental appliances aid in these efforts, and some are worn long after the braces are removed permanently. Orthodontists make their living in diagnosing, applying, and caring for braces in most cases.  

Most orthodontists must attend the normal four-eight year course required for a dentist, with the addition of a two-four year program for the specialty of orthodontics. This procedure is commonly covered by dental health insurance plans, although most times a yearly deductible must be met first. Without insurance, the treatment can cost thousands. Talk to the dental carrier to find out how much a treatment would cost for sure.  

Medical and healthcare professionals sometimes call this area of study dentofacial orthopedics. Those who have had procedures done in this field have improved self-esteem, along with an obviously straighter smile. However, what most do not realize is that orthodontic procedures normally decrease the instance of migraines, relieve tooth or gum pain, and can fix the cracking or popping in the opening/closing of the jaw common to many teens and adults.Not every person’s teeth grow in perfectly spaced and straight. Whether you are considering braces for a child or an adult, we can help determine the best orthodontics to meet every need.

Partial Denture: A removable dental prosthesis (appliance) that replaces one or more natural teeth.

Pathology: The study of disease.

Pedodontics or Pediatric Dentistry:

As the name implies, pediatric dentistry is the field of medicine that deals with dentists for children. A children’s dentist specializes in the care of a child’s small mouth and teeth, normally including braces, invisible braces, crowns, fillings, cleanings, plates, x-rays, and similar tools in everyday work. Caring for the growing mouth of a child is hard work, and requires more education for the specialty of pediatric dentistry.  

A pediatric dentist can give parents and caregivers special information regarding habits that can cause trouble later, such as thumb sucking, cavity-causing eating habits, and much more. They also understand the process of teeth growing, falling out, and allowing adult teeth to grow. Sometimes, teeth must be pulled for a variety of reasons, even for small children.  

Dentists for children are not solely concerned with tooth maintenance. They are also a vital part of a healthy smile as an adult, and can help a child grow up with an improved self-image. Learning about things that make a child healthy and happy is an important part of being a good parent, and finding a dentist that specializes in pediatric dentistry can do just that.Our pediatric dental specialists are trained to deal with the unique needs of children.  This includes calming their fears, specialized equipment and educating them about good oral health.

Prosthesis: An artificial appliance for the replacement for a body part.

Prosthodontist: "Prosthodontics" involves dentures, bridges, crowns, implants, and similar areas of expertise commonly associated with cosmetic dentistry. Many dentists who specialize in prosthodontics also go on to receive special training in oral or maxillofacial surgery or prosthodontics. This allows them to fix or repair other missing facial features such as nose, eyes, and/or ears, to name a few.

Dentures A prosthodontist specializes in replacing parts of the mouth, jaw, or teeth, often using an artificial device such as dentures, partial dentures, and other items to improve the appearance and correct common oral problems. Dentures cost hundreds or even thousands of dollars typically, in addition to prosthodontist fees. However, affordable dentures exist for those who learn how to find them.

Dental Implants Sometimes, a missing tooth will create the need for a dental implant. A dentist typically uses implants replace a missing tooth or teeth. Dental implants are normally made of titanium at the root, with a traditional crown as the tooth itself. They are an excellent alternative to pulling several teeth in order to utilize a bridge or to get dentures. However, dentures can be made from implants, but can be quite costly without dental insurance coverage.

Since dental implants look just like natural teeth, it’s impossible to tell them apart. This is good for those who have had one or more teeth implanted, especially the most visible front teeth. Not having to feel self-conscious about a missing tooth or an obviously different tooth will improve self-image and increase confidence. No matter what age the patient is, allowing a cosmetic dentist to add a dental implant (or more than one) is well worth the cost.

The implant process normally takes about six months overall. First, the mouth must be measured and the tooth/teeth must be created to fit the individual. Then, it must be implanted into the mouth and anchored to the jawbone. After that, it has to have time to heal properly, becoming an extension of the jaw. Finally, the permanent crown is put on the implant and it looks just like a normal tooth. Although the process seems long and complicated, the results will last a very long time.

Dentists who specialize in this field do not simply replace teeth. They also care for and maintain their work, and are constantly assessing the needs of new patients. In most cases, a full is required for this industry, with the addition of at least two more years to learn the specialty aspect. This branch of dentistry is not new, but is becoming more popular each year, as more people turn to dentistry to correct problems.

Most insurance policies cover at least a portion of a prosthodontic procedure, so long as the treatment is not viewed as purely cosmetic. Even then, dental insurance providers may cover at least part of the procedure, depending on such factors as the individual in question, why the treatment is needed, how much it costs, yearly deductibles, and similar factors. Check with the dental insurance carrier to learn more.
