A
Abrasion
Abrasion is the wear of teeth caused by factors other than chewing. This can happen from habits such as clenching objects between the teeth or using incorrect brushing methods. Maintaining proper oral hygiene can reduce this risk.
Abutment
An abutment is a crucial component in dentistry. It denotes a tooth or implant that supports a dental prosthesis, like a bridge or crown, thereby ensuring stability and effectiveness.
Amalgam
Amalgam is an alloy frequently used for direct dental restorations. Renowned for its strength and durability, it continues to be a dependable choice for treating dental cavities.
Analgesia
Analgesia refers to the absence of pain sensation while maintaining consciousness. This method is frequently employed during dental procedures to enhance patient comfort, allowing them to stay alert and engaged.
Apicoectomy
An apicoectomy involves removing the tip of a tooth root, usually performed after a root canal when infection remains. This procedure effectively preserves the natural tooth while addressing the issue.
B
Benign
A term used to describe an illness that is mild or a growth that is harmless and non-cancerous.
Bicuspid (Premolar Tooth)
This is a type of tooth with two distinct cusps. It plays a vital role in chewing and grinding food.
Biopsy
A medical procedure where a small sample of tissue is removed for an in-depth microscopic examination to aid in diagnosis.
Bitewing Radiographs
These are specialised dental X-rays that show the crowns of your upper and lower teeth while you bite down. They are especially useful for detecting cavities and assessing dental health.
Bleaching
A cosmetic dental procedure designed to whiten teeth using a specialised bleaching solution administered by professionals.
Bonding
A flexible dental treatment where composite resin is applied to a tooth to improve its shape or colour. It’s also used to attach orthodontic appliances, fillings, or dentures directly to teeth.
Bridge
A dental structure used to replace missing teeth. It can refer to a Fixed Partial Denture or a Removable Partial Denture.
Bruxism
The habitual clenching or grinding of teeth, either during the day or while asleep. This condition can lead to jaw discomfort or tooth wear.
C
Calculus
Ever noticed those hard, crusty deposits on your teeth that brushing just won’t budge? That’s calculus—a mineral build-up that sticks to your teeth over time. It’s basically hardened plaque and needs a dentist to remove it.
Canal
Think of a canal as a small, narrow passage within your teeth or bones. It’s often talked about in dentistry when referring to the tiny pathways inside a tooth.
Root Canal
This refers to the space running through a tooth’s root where the nerve and pulp live. A root canal treatment cleans this space to stop infections and protect the tooth from future damage.
Cariogenic
Anything that encourages tooth decay is cariogenic. For example, sugary drinks and snacks fuel the bacteria responsible for cavities—so try to enjoy them in moderation!
Cavity
A cavity is damage or decay in your tooth caused by untreated plaque and bacteria. It’s also known as a “carious lesion” and should be treated ASAP to avoid deeper tooth damage.
Cleft Lip
This is a birth defect where there’s a split or gap in the upper lip. It’s something that can usually be corrected with surgery to improve both appearance and function.
Cleft Palate
A cleft palate occurs when the roof of the mouth doesn’t fuse properly during development. It can be partial or complete and usually requires surgery to assist with speaking, eating, and more.
Clenching
Clenching is when you tightly press your teeth and jaws together—often due to stress or intense focus. It can lead to worn-down teeth and even jaw joint issues if it happens a lot.
Composite
This is a blend of materials, like resin and quartz, used to fix cavities or repair chipped teeth. Composites are great because they can match the natural colour of your teeth perfectly.
Conscious Sedation
This keeps you calm and pain-free during a dental procedure while still being conscious. You can breathe and respond normally, but you feel much more relaxed.
Crown
- Anatomical Crown: The visible part of your tooth covered by enamel.
- Abutment Crown: A specialised crown that supports dental bridges or dentures.
- Artificial Crown: A cap that restores the full structure of a damaged tooth.
- Clinical Crown: The portion of a tooth that’s visible above the gums.
- Crown Lengthening: A procedure that exposes more of a tooth for dental work.
Cusp
The pointed bits on the tops of your molars and premolars are called cusps. They help you chew and grind food.
D
Debridement
This is the process of clearing away dead tissue or debris to help a wound heal. Dentists may also use this term when removing tartar or plaque from teeth.
Decay
Decay happens when bacteria in your mouth create acids that break down the tooth’s enamel, causing cavities.
Dental Prophylaxis
This is a professional cleaning done by your hygienist or dentist. It involves scaling to remove tartar and polishing to leave your teeth squeaky clean.
Dental Prosthesis
A prosthesis replaces missing teeth and can come as dentures, bridges, implants, or crowns. It restores your smile and makes chewing easier.
Denture Base
The denture base is the part of your dentures that sits on your gums and holds the artificial teeth in place.
Dry Socket
This painful condition can happen after tooth extraction if the blood clot protecting the area gets dislodged. It needs prompt care to heal properly.
E
Edentulous
This means being completely toothless. Thankfully, dentures or implants can replace those missing teeth and improve oral function.
Enamel
Enamel is the tough outer layer of your teeth—the hardest substance in your body. It protects your teeth from wear, tear, and decay.

F
Filling
A filling is how dentists fix a cavity. They use materials like resin, alloy, or porcelain to restore your tooth’s shape and function.
Fixed Appliances
These are orthodontic devices like braces that stay attached to your teeth to correct alignment over time.
Fixed Partial Denture
Essentially a bridge, this replaces missing teeth and is secured to the surrounding natural teeth or implants.

- Eposteal (Subperiosteal): Positioned on top of the bone under the gum.
- Transosteal (Transosseous): Passed completely through the bone.
Inlay
An inlay is a custom-made restoration crafted outside the mouth to perfectly fit a prepared cavity in a tooth. It’s then securely bonded into place, restoring the tooth’s strength and functionality.
Interproximal
This term describes the small spaces between your teeth—those tricky areas where food and plaque like to hide! These spots require extra attention when brushing and flossing.
Intraoral
The word intraoral simply means “inside the mouth” and is often used to describe exams, dental procedures, or devices that work within the oral cavity.
Intravenous Sedation
Intravenous (IV) sedation involves delivering medications straight into the bloodstream to help keep you calm and comfortable during dental treatments. It’s a technique often used for anxious patients or lengthy procedures.
M
Malocclusion
Malocclusion refers to misaligned teeth or jaws that can lead to chewing problems, speech issues, or discomfort. Treatments like braces or retainers are often used to correct it, ensuring a functional and healthy bite.
Maryland Bridge
A Maryland bridge is a type of dental prosthetic used to replace missing teeth. Unlike traditional bridges, it doesn’t require crowns on neighbouring teeth. Instead, it’s bonded directly to existing teeth, making it a less invasive option.
Molar
Molars are the large, strong teeth at the back of your jaw. Their broad surfaces are designed for grinding and breaking down food, making them essential for chewing.
Mouthguard
A mouthguard is a protective device worn over the teeth to prevent injuries during sports or to manage conditions like teeth grinding (bruxism). They’re a must-have for athletes and a useful tool for protecting your smile.
