A Crown is a type of dental restoration which completely caps or encircles a tooth or dental implant and is typically bonded to the tooth using a dental cement. Crowns can be made from many materials, which are usually fabricated using indirect methods. <br> The most common method of crowning a tooth involves using a dental impression of a prepared tooth by a dentist to fabricate the crown outside of the mouth. The crown can then be inserted at a subsequent dental appointment. Using this indirect method of tooth restoration allows use of strong restorative materials requiring time consuming fabrication methods. '
Dentures are prosthetic devices constructed to replace missing teeth, and which are supported by surrounding soft and hard tissues of the oral cavity. Conventional dentures are removable, however there are many different denture designs, some which rely on bonding or clasping onto teeth or dental implants. There are two main categories of dentures, depending on whether they are used to replace missing teeth on the mandibular arch or the maxillary arch. There are many colloquial terms for dentures such as dental plate, false teeth, choppers falsies & gnashers
Dental bleaching, also known as tooth whitening, is a common procedure in general dentistry but most especially in the field of cosmetic dentistry. A child\'s deciduous teeth are generally whiter than the adult teeth that follow. As a person ages the adult teeth often become darker due to changes in the mineral structure of the tooth, as the enamel becomes less porous. Teeth can also become stained by bacterial pigments, foodstuffs and tobacco. Certain antibiotic medications (like tetracycline) can also lead to teeth stains or a reduction in the brilliance of the enamel.
In dentistry, a veneer is a thin layer of restorative material placed over a tooth surface, either to improve the aesthetics of a tooth, or to protect a damaged tooth surface. There are two main types of material used to fabricate a veneer, composite and porcelain. A composite veneer may be directly placed (built-up in the mouth), or indirectly fabricated by a dental technician in a dental laboratory, and later bonded to the tooth, typically using a resin cement such as Panavia. In contrast, a porcelain veneer may only be indirectly fabricated.
Root Canal therapy is a sequence of treatment whose end result is the elimination of infection and protection of the decontaminated tooth from future microbial invasion. Although this set of procedures is commonly referred to as a root canal, this term is imprecise; root canals and their associated pulp chamber are the hollows within a tooth which inhabit nerve tissue, blood vessels and other cellular entities. Whereas endodontic therapy, commonly referred to as a Root Canal, includes the complete removal of these structures, the subsequent cleaning, shaping and decontamination of these hollows with the use of tiny files and the filling of the decontaminated root canals. After the surgery the tooth will be \"dead\", and if the infection is spread at apex, root end surgery is required.
Sonic and ultrasonic scalers are powered by a system that causes the tip to vibrate. Sonic scalers are typically powered by an air-driven turbine. Ultrasonic scalers typically use either magnetostrictive or piezoelectric systems to create vibration. Magnetostrictive scalers use a stack of metal plates bonded to the tool tip. The stack is induced to vibrate by an external coil connected to an AC source. Many ultrasonic scalers also include a liquid output or lavage, which aids in cooling the tool during use. The lavage can also be used to deliver antimicrobial agents. There is some debate over whether there is an advantage to sonic or ultrasonic scaling over hand scaling and some issues arise from powered scalers. However, powered scalers tend to create aerosols, which can spread pathogens.
A dental restoration or dental filling is a dental restorative material used to restore the function, integrity and morphology of missing tooth structure. The structural loss typically results from external trauma. It is also lost intentionally during tooth preparation to improve the aesthetics or the physical integrity of the intended restorative material. Dental restoration also refers to the replacement of missing tooth structure which is supported by dental implants. Dental restorations can be divided into two broad types: direct restorations and indirect restorations. All dental restorations can be further classified by their location and size. A root canal filling is a restorative technique used to fill the space where the dental pulp normally resides.
A dental extraction (also referred to as exodontia) is the removal of a tooth from the mouth. Extractions are performed for a wide variety of reasons, including tooth decay that has destroyed enough tooth structure to prevent restoration. Extractions of impacted or problematic wisdom teeth are routinely performed, as are extractions of some permanent teeth to make space for orthodontic treatment.
Dental impactions are often known to occur when there is not enough room in the jaw for new molar teeth to erupt properly. This can lead to a variety of dental problems, including cysts. There are several types of dental impaction such as wisdom teeth removal, extraction-symptoms, pains & complications.
