A dental abscess is a painful pocket of pus caused by a bacterial infection in the teeth, gums, or surrounding tissues. It can result from untreated cavities, gum disease, or tooth trauma and often causes severe pain, swelling, fever, and bad breath. Treatment typically involves draining the abscess, prescribing antibiotics, and addressing the underlying issue through procedures like root canals or extractions.
Amalgam fillings are strong and durable restorations made from a mix of metals, including mercury, silver, tin, and copper, commonly used to repair decayed teeth. They are especially effective for molars due to their ability to withstand heavy chewing forces, though their metallic appearance and mercury content may lead some patients to prefer other options.
Dental anesthesia involves techniques to numb the mouth and ensure a pain-free procedure. Common types include local anesthesia for specific areas, nitrous oxide ("laughing gas") for relaxation, and general anesthesia for complex surgeries. These methods are tailored to the patient’s needs and the procedure's complexity.
The apex is the tip of a tooth’s root, where nerves and blood vessels enter. It plays a crucial role in maintaining the tooth’s vitality. The apex is often the focus of root canal treatments, which aim to remove infection and seal the area to protect the tooth.
An apicoectomy is a minor surgical procedure to remove the infected tip of a tooth’s root when a root canal has failed. This procedure helps save the tooth by cleaning and sealing the area to prevent further issues.
Attrition is the gradual wearing down of teeth caused by chewing or grinding. It often results in flattened surfaces, sensitivity, or enamel loss. Preventive measures like bite guards and dental treatments can help manage its effects.
The alveolar bone supports and anchors teeth in the jaw. Bone loss in this area, often caused by gum disease or tooth loss, can weaken the jaw structure and require treatments like grafting for restoration.
Abrasion is the loss of tooth enamel caused by mechanical forces, such as aggressive brushing or using abrasive toothpaste. It can lead to sensitivity and an increased risk of cavities, which are often managed by changing habits and applying protective treatments.
Aesthetic dentistry focuses on improving the appearance of teeth and gums through treatments like whitening, veneers, bonding, and orthodontics, helping patients achieve a healthier, more attractive smile.
Anterior teeth include the incisors and canines at the front of the mouth. They are essential for cutting and tearing food. They also play a key role in speech and smile aesthetics.
Bruxism is the involuntary grinding or clenching of teeth, often occurring during sleep or times of stress. It can lead to excessive tooth wear, jaw pain, headaches, and even temporomandibular joint (TMJ) disorders. Treatment options include stress management, nightguards, and in severe cases, dental corrections to adjust the bite.
A dental bridge is a fixed restoration used to replace one or more missing teeth by anchoring to adjacent healthy teeth or dental implants. It restores the appearance and functionality of the smile, preventing issues like teeth shifting or bone loss. Bridges can be made from materials such as porcelain, metal, or a combination of both.
Dental bonding is a procedure where a tooth-colored resin material is applied to a tooth, shaped, and hardened with a special light. This treatment repairs chips, cracks, or discoloration and can reshape or lengthen teeth. Bonding is quick, cost-effective, and ideal for minor cosmetic improvements.
A bitewing X-ray captures detailed images of the upper and lower teeth in one small section of the mouth, making it ideal for detecting cavities between teeth and assessing bone health. These X-rays are often taken during routine dental check-ups to monitor oral health.
Bicuspids, or premolars, are the teeth located between the canines and molars. They have a flat surface with ridges for chewing and grinding food and are essential for breaking down food into smaller, digestible pieces. Adults typically have eight bicuspids, four in each jaw.
A dental biopsy involves removing a small sample of oral tissue to diagnose conditions such as oral cancer, infections, or abnormal growths. The tissue is examined under a microscope to determine if further treatment is needed, making it a critical tool for early detection and management of oral diseases.
Teeth bleaching is a cosmetic procedure designed to remove stains and lighten the color of teeth using peroxide-based solutions. It can be performed in-office for immediate results or at home with custom trays. This treatment enhances smile aesthetics but requires maintenance to preserve results.
Braces are orthodontic devices that use brackets, wires, and bands to align and straighten teeth while correcting bite issues (malocclusions). They gradually shift teeth into their proper positions, improving both aesthetics and oral health. Modern options include traditional metal braces, ceramic braces, and clear aligners.
A bone graft is a surgical procedure used to rebuild or augment jawbone density, often necessary before placing dental implants. It involves transplanting bone material from the patient, a donor, or synthetic sources to restore bone volume and support dental restorations.
Biocompatible materials are those that are safe and non-toxic for use in dental procedures, ensuring they do not cause adverse reactions in the body. These materials, such as titanium for implants or composite resins for fillings, promote healing and long-term success of dental treatments.
A cavity is a hole or area of decay in a tooth caused by bacteria breaking down sugars into acid, which erodes the enamel and dentin layers. If untreated, it can lead to pain, sensitivity, and infections that may require extensive treatment. Cavities are commonly treated with fillings, inlays, or crowns, depending on the severity, and prevented with proper oral hygiene and regular dental check-ups.
Cementum is a calcified tissue that covers the roots of teeth, anchoring them to the jawbone through periodontal ligaments. It protects the root and provides stability for chewing. While not as hard as enamel, cementum is essential for overall tooth structure and health, but it can become exposed and vulnerable due to gum recession or disease.
Composite resin is a versatile, tooth-colored material used for fillings, bonding, and veneers. It is highly durable and mimics the natural appearance of teeth, making it ideal for aesthetic restorations. This material bonds directly to the tooth structure, providing strength and a seamless finish for both minor and major dental repairs.
A dental crown is a custom-made cap placed over a damaged or decayed tooth to restore its shape, size, strength, and appearance. Crowns are made from materials such as porcelain, metal, or zirconia and protect the tooth from further damage while enhancing functionality and aesthetics.
Calculus, or tartar, is hardened plaque that forms on teeth when not removed through regular brushing and flossing. It can cause gum inflammation, bad breath, and eventually lead to gum disease. Tartar cannot be removed at home and requires professional cleaning by a dentist or hygienist.
A canal refers to the hollow space within the root of a tooth that houses nerves, blood vessels, and connective tissue. Infections or damage to this area require root canal therapy to clean, disinfect, and seal the canal, preserving the tooth and preventing further complications.
Canines are the pointed teeth located between the incisors and premolars, designed for tearing and holding food. Humans typically have four canines, two on the upper and two on the lower jaw. They play a vital role in biting, guiding the bite during chewing, and contributing to a balanced smile.
Chronic periodontitis is a progressive form of gum disease caused by prolonged bacterial infection and inflammation. It damages the gums and the bone supporting the teeth, leading to tooth mobility and eventual tooth loss if untreated. Treatment includes deep cleaning, medications, and sometimes surgery to halt progression and restore oral health.
Crown lengthening is a surgical procedure to expose more of a tooth's surface by removing excess gum or bone tissue. It is commonly performed to prepare for restorations like crowns or to improve the appearance of a gummy smile, enhancing both functionality and aesthetics.
Cosmetic dentistry focuses on enhancing the appearance of teeth, gums, and smiles through procedures like veneers, whitening, bonding, and orthodontics. It combines artistry with dental expertise to address discoloration, misalignment, chips, or gaps, boosting confidence and oral aesthetics.
Dentures are removable prosthetic devices that replace missing teeth and surrounding tissues, restoring functionality and aesthetics. Full dentures replace all teeth in the upper or lower arch, while partial dentures fill gaps between remaining natural teeth. They are custom-made for each patient and require proper care to maintain oral health and comfort.
Dental decay, or caries, occurs when bacteria in plaque convert sugars into acid, which erodes tooth enamel. If untreated, it can progress to the dentin and pulp, causing pain, sensitivity, and infection. Treatment includes fillings, crowns, or root canals, while prevention focuses on good oral hygiene and reduced sugar intake.
Dentin is the softer layer beneath the enamel and cementum, forming the bulk of a tooth's structure. It contains microscopic tubules connecting to the pulp, making it sensitive when exposed to decay or erosion. Protecting dentin with enamel or restorations is essential to prevent discomfort and further damage.
A dental implant is a titanium post surgically inserted into the jawbone to act as an artificial tooth root. It provides a stable foundation for crowns, bridges, or dentures, restoring the function and appearance of missing teeth. Implants also prevent bone loss and maintain the jaw's structure over time.
A diastema is a gap or space between two teeth, most commonly between the upper front teeth. While often harmless, some patients choose to close the gap using orthodontics, veneers, or bonding for aesthetic or functional reasons. Diastemas can sometimes result from underlying issues like gum disease or improper bite alignment.
Dry socket is a painful condition after tooth extraction when the protective blood clot dislodges, exposing the underlying bone and nerves. Symptoms include severe pain, bad breath, and a visible empty socket. Treatment involves cleaning the area, applying medicated dressings, and managing pain to promote healing.
A dental sealant is a thin, protective coating applied to the chewing surfaces of molars and premolars to prevent cavities. It seals deep grooves and pits where plaque and food particles often accumulate, offering an extra defence against decay, particularly in children and teens.
A dental hygienist is a licensed professional specializing in preventive oral care, including cleaning teeth, removing tartar, and applying fluoride treatments. They also perform oral health assessments, educate patients on proper hygiene practices, and identify potential issues requiring a dentist's attention.
Digital X-rays are advanced imaging tools that diagnose dental issues with minimal radiation exposure. They produce high-resolution images of teeth, roots, and bone structures, aiding in detecting cavities, infections, and bone loss. The digital format allows for quick sharing and enhanced diagnostic accuracy.
Edentulism is the loss of all or some natural teeth, which can occur due to decay, gum disease, trauma, or aging. Partial edentulism affects only some teeth, while complete edentulism means no natural teeth remain. This condition can impact chewing, speech, and facial aesthetics, and it is often treated with dentures or dental implants to restore function and appearance.
Enamel is the hard outer layer of a tooth that serves as the first line of defence against decay and physical damage. Although it is the most vital substance in the body, it can erode over time due to acid from food, beverages, or improper brushing techniques. Protecting enamel through good oral hygiene and fluoride use is essential to maintaining dental health.
Endodontics is a dental specialty focused on diagnosing and treating diseases of the dental pulp and surrounding tissues. It often involves root canal therapy, a procedure to remove infected or damaged pulp, clean the root canals, and seal them to prevent further infection and preserve the natural tooth.
Eruption is the process by which teeth emerge through the gums. This occurs twice in a lifetime—first with primary (baby) teeth, typically between 6 months and 3 years old, and later with permanent teeth, starting around age 6. The timing and sequence of eruption can vary, and complications such as impaction or crowding may require intervention.
Exodontia is the dental field concerned with tooth extraction, performed for reasons such as severe decay, trauma, crowding, or impacted wisdom teeth. Depending on the complexity, extractions can be simple or surgical and are often followed by restorative treatments like implants or bridges to maintain oral health.
Dental erosion is the chemical loss of enamel due to acid exposure from foods, beverages, or medical conditions like acid reflux. Unlike cavities caused by bacteria, erosion results directly from acid’s effect on enamel, leading to sensitivity, discoloration, and weakened teeth. Preventive measures include limiting acidic foods and using fluoride products.
Eugenol is a natural compound derived from clove oil, widely used in dentistry for its antiseptic, anti-inflammatory, and anesthetic properties. It is commonly found in temporary fillings, sedative dressings, and root canal sealers, relieving pain and reducing infection risk during treatment.
Emergency dentistry addresses urgent dental issues such as severe pain, broken teeth, infections, or trauma. Immediate treatment is crucial to alleviating discomfort, preventing complications, and restoring oral function. Common procedures include extractions, root canals, and temporary restorations.
Exostosis is the abnormal growth of bone in the jaw or mouth, such as tori (bony projections on the palate or lower jaw). These growths are typically benign and only require removal if they interfere with oral function, such as fitting dentures or irritating.
Epulis is a benign growth on the gum tissue, often caused by irritation, trauma, or hormonal changes. While usually painless, larger growths can affect oral function and aesthetics. Treatment involves surgical excision and addressing the underlying cause to prevent recurrence.
Fluoride is a naturally occurring mineral essential for strengthening tooth enamel and preventing cavities. It works by remineralizing weakened enamel and making teeth more resistant to bacterial acid attacks. Found in toothpaste, mouth rinses, and fluoridated public water supplies, fluoride is a cornerstone of preventive dental care. Dentists may also apply fluoride treatments for additional protection, particularly for children and individuals prone to decay.
A dental filling is a restorative procedure to repair a tooth damaged by decay or trauma. Materials like amalgam (a durable metal blend), composite resin (tooth-coloured), and gold fill cavities, restore tooth structure, and prevent further damage. Modern fillings blend aesthetics and function, ensuring long-term protection and a natural appearance.
A frenectomy is a minor surgical procedure that involves removing or modifying the frenulum, a small fold of tissue in the mouth that connects the lips or tongue to the gums. This procedure is often performed to improve mobility, such as in cases of tongue-tie (ankyloglossia), or to address gaps between teeth caused by a thick frenulum.
Fissures are deep grooves or pits found on the chewing surfaces of molars and premolars, making them susceptible to plaque and decay. Since these grooves can be challenging to clean with brushing alone, dental sealants are often applied to fill and protect them, reducing the risk of cavities in these areas.
Flossing is an essential oral hygiene practice that involves using dental floss to remove plaque and food particles from between teeth and under the gumline. It prevents gum disease, cavities, and bad breath by reaching areas that brushing cannot. Regular flossing is vital for maintaining healthy gums and teeth..
Dental fluorosis is a cosmetic condition caused by excessive fluoride intake during tooth development. It results in white spots, streaks, or, in severe cases, brown mottling of the enamel. Although it does not affect tooth function, it can be aesthetically concerning. Prevention involves monitoring fluoride exposure, especially in young children.
Full-mouth reconstruction refers to a series of comprehensive dental treatments designed to restore or replace most or all teeth, improving oral function, aesthetics, and health. This process often includes procedures like crowns, bridges, dental implants, veneers, and orthodontics, tailored to address specific needs such as severe decay, tooth loss, or bite issues.
A foramen is a natural opening in a bone that allows the passage of nerves and blood vessels. In dentistry, the mental foramen in the lower jaw is particularly significant, as it provides a pathway for nerves and arteries supplying the lower teeth and lip. Understanding its location is crucial during surgical and restorative procedures.
Facial trauma refers to injuries to the face or jaw caused by accidents, falls, or sports-related incidents. These injuries can affect teeth, gums, bones, and soft tissues, often requiring emergency dental care, surgical intervention, or reconstruction to restore function and appearance. Prompt treatment is essential to prevent complications.
A fixed partial denture, commonly called a dental bridge, is a non-removable restoration used to replace one or more missing teeth. Anchored to adjacent teeth or implants, it restores chewing ability, prevents remaining teeth from shifting, and maintains facial structure. Bridges are designed to blend seamlessly with natural teeth for a functional and aesthetic solution.
Gingiva, or gums, are the soft tissues that surround and protect the base of the teeth. They form a seal that prevents bacteria from reaching deeper oral structures. Healthy gums are pink, firm, and free from bleeding, while redness, swelling, or tenderness often indicates inflammation or disease, requiring professional care and improved oral hygiene.
Gingivitis is the earliest stage of gum disease, characterized by redness, swelling, and bleeding, particularly during brushing or flossing. It is caused by plaque buildup at the gumline and is reversible with proper oral hygiene, regular dental cleanings, and addressing contributing factors like smoking or poor diet.
A gum graft is a surgical procedure to repair or rebuild gum tissue lost due to recession or injury. It involves transplanting tissue, often from the roof of the mouth, to cover exposed roots, improve aesthetics, and reduce sensitivity. This procedure also helps prevent further recession and protects the tooth from decay.
A general dentist is a primary dental care provider who offers a wide range of services, including cleanings, fillings, extractions, and crowns. They are trained to diagnose, treat, and prevent oral health issues, serving as the first point of contact for maintaining overall dental wellness and managing referrals to specialists when needed.
Gum recession occurs when gum tissue pulls back from the teeth, exposing the roots. This condition can result from aggressive brushing, gum disease, or bruxism and often causes sensitivity and increased risk of decay. Treatments include deep cleaning, gum grafting, and lifestyle changes to address the underlying cause.
Grinding, or bruxism, is the involuntary clenching or grinding of teeth, often during sleep or times of stress. It can cause tooth wear, jaw pain, headaches, and even cracks in teeth. Treatment includes using nightguards to protect teeth, managing stress, and correcting bite issues if needed.
Gum contouring is a cosmetic dental procedure that reshapes the gumline to improve the appearance of a gummy smile or uneven gums. Using a laser or scalpel, excess gum tissue is removed to expose more of the tooth, creating a balanced and aesthetically pleasing smile
Gutta-percha is a biocompatible, rubber-like material used in root canal therapy to fill the cleaned and shaped root canals of a tooth. It seals the space to prevent reinfection and provides structural support for the tooth, often followed by a crown for additional protection.
A gold crown is a dental restoration made from gold or a gold alloy, prized for its durability, longevity, and compatibility with oral tissues. While less common for visible teeth due to its metallic appearance, it is an excellent choice for molars, where strength is essential for chewing.
The gag reflex is an involuntary reaction triggered when the back of the mouth or throat is touched, often causing discomfort during dental procedures. Dentists manage this response using techniques such as distraction, numbing sprays, or sedation, ensuring a more comfortable experience for the patient.
Halitosis, or persistent bad breath, is often caused by poor oral hygiene, gum disease, or food debris accumulating in the mouth. Other causes include dry mouth, smoking, or systemic conditions such as diabetes or gastrointestinal issues. Proper brushing, flossing, tongue cleaning, and regular dental check-ups can help address the issue, while underlying medical conditions may require specialized treatment.
