Dental words,
plainly explained.

A localized pocket of pus caused by a bacterial infection in a tooth or the gum tissue around it. Abscesses can be painful and need prompt treatment to stop the infection from spreading.

A connector piece placed on top of a dental implant — or a natural tooth used to anchor a bridge — that supports the final crown, bridge, or denture.

A durable, silver-colored filling material made from a blend of metals including silver, tin, copper, and a small amount of mercury. Largely replaced today by tooth-colored composite.

Medication that prevents you from feeling pain during a procedure. In dentistry, this is most often a small injection of local anesthetic that numbs only the area being treated.

A small surgical procedure that removes the very tip of a tooth root and seals the canal, usually performed when a previous root canal hasn’t fully healed.

A locally applied antibiotic (minocycline microspheres) placed directly into infected periodontal pockets after scaling and root planing to help fight gum disease.

A custom-fitted shield worn during sports to protect your teeth, lips, and jaw from injury. A custom guard fits better and lasts longer than a boil-and-bite.

The way your upper and lower teeth come together when you close your mouth. A healthy bite spreads chewing forces evenly across all of your teeth.

Also called occlusal adjustment — gentle reshaping of the biting surfaces of teeth so your bite balances evenly. Often used to ease grinding, clenching, or jaw soreness.

A cosmetic treatment in which tooth-colored composite resin is sculpted onto a tooth to repair small chips, close gaps, or smooth out discoloration. Usually done in a single visit.

A procedure that adds bone (or a bone-like material) to areas of the jaw that have shrunk after tooth loss or gum disease. Often used to prepare a site for a future dental implant.

Orthodontic appliances — typically metal or ceramic brackets and wires — that gradually move teeth into better alignment. A traditional alternative to clear aligners.

A fixed restoration that replaces one or more missing teeth by anchoring a prosthetic tooth to the natural teeth (or implants) on either side of the gap.

The habit of grinding or clenching your teeth, often during sleep. Long-term bruxism wears down enamel and can cause headaches and jaw pain. A custom night guard usually helps.

The side of a back tooth that faces your cheek. (Front teeth use the term “labial” for the side that faces your lip.)

Hardened plaque that has mineralized onto your teeth. Once it forms, calculus can only be removed by a dental professional during a cleaning.

A small hole in a tooth caused by bacterial acid breaking down the enamel. Cavities don’t heal on their own — they’re treated with a filling, inlay, or crown depending on size.

A 3D imaging scan that captures a detailed view of your teeth, jawbone, nerves, and sinuses. Used for implant planning, complex extractions, and accurate diagnosis.

A routine professional cleaning that removes plaque, tartar, and surface stains. Recommended every six months for most patients to prevent cavities and gum disease.

A tooth-colored filling material made of plastic and fine glass particles. Composite bonds directly to the tooth and blends in for a natural, seamless look.

Treatment focused on the appearance of your teeth, gums, or smile — including whitening, veneers, bonding, and cosmetic alignment. Often combined with restorative care.

A custom cap that covers a damaged or weakened tooth to restore its shape, strength, and appearance. Made from porcelain, ceramic, zirconia, or metal alloys.

A small surgical procedure that gently reshapes the gumline to expose more of a tooth — useful before a crown or to even out a “gummy” smile.

A deep-cleaning step that removes diseased tissue from inside a periodontal pocket so the gum can heal back tightly against the tooth.

The gradual breakdown of tooth structure caused by acids from plaque bacteria. The medical term is dental caries; the common term is tooth decay.

Another name for primary or “baby” teeth — the first set of 20 teeth that erupt in childhood and are eventually replaced by permanent teeth.

A small titanium post placed into the jawbone to act as a replacement tooth root. Once it fuses with the bone, an abutment and crown are attached on top.

The bone-like layer just beneath your enamel that makes up most of the tooth. Dentin is softer than enamel and contains tiny tubules that connect to the nerve.

A removable appliance that replaces all of your teeth (full denture) or just some of them (partial denture) in an arch. Modern dentures look and fit far better than older ones.

A modern dental X-ray that uses a digital sensor instead of film. Images appear instantly, and radiation exposure is roughly 80–90% lower than traditional X-rays.

A small soft-tissue laser used for gentle gum reshaping, uncovering teeth, and treating early gum disease. Most procedures need little or no anesthesia.

A treatment used when decay is very close to the nerve. A protective medication is placed over the exposed pulp and sealed under a filling, often saving the tooth from a root canal.

Chronically reduced saliva flow, often caused by medications. Without enough saliva, the risk of cavities and gum disease climbs — there are simple products and routines that help.

A painful complication that can follow a tooth extraction if the protective blood clot is lost too soon. It’s easily treated with a medicated dressing in the socket.

The hard, white outer layer of the tooth crown. Enamel is the hardest substance in the human body, but it can be eroded by acids and damaged by decay or grinding.

Also called contouring — a quick, gentle smoothing of small surface irregularities to improve the shape and appearance of natural teeth. Usually no anesthesia is needed.

The branch of dentistry that deals with the inside of the tooth — the pulp and the root canals. Root canal treatment is the most familiar endodontic procedure.

Removing a tooth from its socket. A simple extraction uses gentle pressure on a fully visible tooth; a surgical extraction is used when a tooth is broken or impacted.

A naturally occurring mineral that strengthens tooth enamel and helps reverse early decay. You’ll find it in toothpaste, most public water, and in-office topical treatments.

A small procedure that releases a tight band of tissue (a frenum) under the lip or tongue. Often done to address tongue-tie, gum recession, or a gap between the front teeth.

The clinical name for your gums — the soft tissue that surrounds and protects the bone supporting each tooth.

The earliest, reversible stage of gum disease. Signs include red, puffy, or bleeding gums. With a thorough cleaning and improved home care, gums can return to full health.

A procedure that places healthy gum tissue over an area where the gums have receded, helping protect the root, reduce sensitivity, and restore a more even gumline.

The clinical term for chronic bad breath. It’s usually traced to bacteria on the tongue and gums, gum disease, or dry mouth — all of which can be addressed.

A tooth that hasn’t fully come in because it’s blocked by bone, gum, or another tooth. Wisdom teeth and upper canines are the most common offenders.

The visible part of an implant tooth — the abutment and crown that are attached to the implant post once it has fully healed in the bone.

A custom-made restoration that fits inside the cusps of a back tooth. Inlays are stronger than a standard filling and used when too much tooth is missing for a regular filling but a crown isn’t yet needed.

Also called enamel stripping — a thin polish between teeth used during clear-aligner or braces treatment to make small amounts of room for proper alignment.

A clear-aligner system that gently moves teeth into place without metal brackets or wires. Aligners are removable, switched out roughly every one to two weeks.

Sedative medication delivered through a small IV line. You stay responsive but feel deeply relaxed throughout your appointment. Used for longer or more involved procedures.

Surgery used to correct significant misalignment between the upper and lower jaws. Usually planned alongside orthodontic treatment to improve both function and appearance.

A bite that doesn’t fit together correctly — overbite, underbite, crossbite, or crowding. Often treated with clear aligners or braces; severe cases may need surgery.

A custom-fit appliance worn during sleep to protect teeth from grinding and to ease jaw and headache pain. A custom guard is far more comfortable than a store-bought one.

A safe, mild inhaled sedative — also known as laughing gas — that helps you feel calm and comfortable during treatment. Effects wear off within minutes after the mask is removed.

Fine reshaping of the biting surfaces of teeth so your bite balances evenly. Often used to relieve grinding, jaw tension, or a single tooth that hits “high.”

A custom restoration that covers one or more cusps of a back tooth — larger than an inlay, smaller than a full crown. A great way to preserve healthy tooth structure.

A quick, comfortable visual and tactile exam of your lips, tongue, cheeks, and throat. Early detection is the single biggest factor in successful treatment of oral cancers.

The branch of dentistry that handles surgical care of the mouth and jaw — including extractions, implant placement, biopsies, and treatment of facial trauma.

The branch of dentistry that focuses on straightening teeth and correcting bite issues using clear aligners, braces, and other appliances.

The biological process in which a dental implant fuses with the surrounding jawbone, creating a stable, long-lasting foundation for a replacement tooth.

A removable denture that snaps onto a few dental implants or remaining roots. Far more stable and comfortable than a traditional denture, with no slipping when you talk or eat.

A removable replacement for several missing teeth that clasps to your remaining natural teeth. A budget-friendly alternative to a bridge or implant.

The area at the very tip of a tooth root. A periapical X-ray shows the entire tooth from crown to root tip and the surrounding bone.

A long-term infection of the gums and bone that hold your teeth in place. Ranges from mild gingivitis to advanced periodontitis, which can cause tooth loss if untreated.

Specialized cleanings — usually every three to four months — that keep gum disease under control after initial treatment, reaching just below the gumline where everyday brushing can’t.

Surgical care for advanced gum disease — including pocket reduction, regenerative therapy, and gum or bone grafting — used to restore the foundation around the teeth.

The soft, sticky film of bacteria that constantly forms on your teeth. Brushing and flossing remove plaque before it hardens into tartar and starts causing damage.

Thin, custom porcelain shells bonded to the front of teeth to refine shape, color, and alignment. A common cosmetic upgrade for chips, gaps, or stubborn discoloration.

The clinical name for a routine professional cleaning. The goal is preventive: stay ahead of cavities, gum disease, and stains before they can take hold.

The innermost part of the tooth — a soft chamber of nerves and blood vessels. When the pulp becomes infected, root canal treatment removes it and saves the tooth.

A baby-tooth procedure that removes only the infected upper portion of the pulp while preserving the healthy lower portion, so the tooth can remain in place until it’s naturally replaced.

A general term for anything that rebuilds a tooth — fillings, inlays, onlays, crowns, bridges, dentures, and implant crowns are all considered restorations.

A custom appliance worn after braces or aligners to hold your teeth in their new positions. Retainers are not optional — teeth want to drift back without one.

A small grafting procedure that rebuilds the natural curve of the jaw ridge after tooth loss, usually to prepare a site for a dental implant or improve the look of a bridge.

A treatment that removes infected or inflamed pulp from inside a tooth, cleans and shapes the canals, and seals them. Modern root canals are typically as comfortable as a filling.

Smoothing the root surfaces of teeth below the gumline to remove bacteria and deposits. Performed alongside scaling to help gums reattach to the teeth.

A thin, soft sheet placed around a tooth during root canals or fillings to keep the area clean, dry, and isolated from the rest of the mouth.

A deep cleaning that removes plaque and tartar from below the gumline (scaling) and smooths the root surfaces (planing). The first-line treatment for moderate gum disease.

A thin, protective coating brushed onto the chewing surfaces of back teeth to seal out plaque. Most often used for kids and teens, but adults at higher risk benefit too.

Care that uses nitrous oxide, oral sedatives, or IV sedation to help anxious patients (or those needing longer procedures) feel relaxed and comfortable in the chair.

A bone-grafting procedure that gently raises the sinus floor and adds bone in the upper back jaw, creating room for a future dental implant when natural bone is shallow.

A custom oral device worn at night to gently hold the lower jaw forward, keeping the airway open. An effective option for mild to moderate sleep apnea, especially when CPAP isn’t a good fit.

A small appliance placed after a baby tooth is lost early. It holds the gap open so the permanent tooth has room to come in straight.

Bonding loose teeth together so they share chewing forces, used after trauma or for teeth weakened by gum disease. The splint is invisible from the front and removable when no longer needed.

Care focused on protecting and treating athletes — including custom mouthguards, treatment of sports injuries, and guidance on getting safely back on the field.

Temporomandibular joint disorder — a condition affecting the jaw joint and chewing muscles. Symptoms include clicking, locking, jaw soreness, and headaches; treatment ranges from a night guard to physical therapy.

A condition in which the band of tissue under the tongue is too short or tight, limiting movement. A simple frenectomy releases it and improves speech, feeding, and oral hygiene.

Treatments that lift surface and deeper stains to brighten the natural color of your teeth. Available as in-office sessions or custom take-home trays.

A thin shell of porcelain or composite resin bonded to the front of a tooth to refine its shape, color, size, or alignment. A go-to cosmetic upgrade for the smile line.

A set of conservative treatments — including pulpotomy and pulp capping — that try to keep the nerve of a tooth alive after deep decay or trauma, avoiding a full root canal when possible.

A device that uses a steady stream of pulsing water to clean between teeth and along the gumline. A great companion (or alternative) to traditional floss, especially around braces and implants.

A step in making dentures where you try on a wax version of the final teeth so the fit, bite, and look can be perfected before the permanent denture is finished.

Custom-fit trays you wear at home with professional whitening gel. Slower than in-office whitening but gentler on sensitive teeth and easy to refresh anytime.

The third set of molars, usually arriving between ages 17 and 25. Many wisdom teeth are crowded or impacted and need to be removed to protect the teeth in front of them.

The clinical term for chronic dry mouth. It’s often a side effect of medication and increases the risk of cavities and gum disease — there are simple products that bring relief.

A crown made from a gold alloy. Gold is gentle on opposing teeth and exceptionally durable — still a top choice for back teeth in patients who grind.

A soothing dental cement often used for temporary crowns and fillings. The eugenol (clove oil) component helps calm the underlying nerve while the tooth heals.

A high-strength ceramic used for crowns, bridges, and implants. Zirconia is tooth-colored, metal-free, and tough enough to handle the back of the mouth.

A specialized implant anchored into the cheekbone (zygoma) instead of the jawbone. Used in patients with severe upper-jaw bone loss to avoid extensive grafting.
