Tooth loss is a process in which one or more teeth come loose and fall out. Tooth loss is normal for deciduous teeth (baby teeth) , when they are replaced by a person's adult teeth . Otherwise, losing teeth is undesirable and is the result of injury or disease, such as dental avulsion , tooth decay , and gum disease .
Composites and amalgam are used mainly for direct restoration. Composites can be made of color matching the tooth, and the surface can be polished after the filling procedure has been completed. Amalgam fillings expand with age, possibly cracking the tooth and requiring repair and filling replacement, but chance of leakage of filling is less.
A glass ionomer cement (GIC) is a dental restorative material used in dentistry as a filling material and luting cement, [1] including for orthodontic bracket attachment. [2] Glass-ionomer cements are based on the reaction of silicate glass-powder (calciumaluminofluorosilicate glass [ 3 ] ) and polyacrylic acid , an ionomer .
This discussion of the dental amalgam controversy outlines the debate over whether dental amalgam (the mercury alloy in dental fillings) should be used. Supporters claim that it is safe, effective and long-lasting, while critics argue that amalgam is unsafe because it may cause mercury poisoning and other toxicity .
Structure of dental inlays and onlays. In dentistry, inlays and onlays are used to fill cavities, [1] and then cemented in place in the tooth. This is an alternative to a direct restoration, made out of composite, amalgam or glass ionomer, that is built up within the mouth.
The most common location of dry socket: in the socket of an extracted mandibular third molar (wisdom tooth). Since alveolar osteitis is not primarily an infection, there is not usually any pyrexia (fever) or cervical lymphadenitis (swollen glands in the neck), and only minimal edema (swelling) and erythema (redness) is present in the soft tissues surrounding the socket.
Temporary filling-materials allow the creation of hermetic coronal-seals preventing from coronal microleakage (i.e. contamination of the root canal by bacteria); their presence over the entire time-period to fill the root canal and restore the tooth crown is mandatory, for increasing the probability of the endodontic-treatment success.
In its early stage, called gingivitis, the gums become swollen and red and may bleed. [5] It is considered the main cause of tooth loss for adults worldwide. [7] [8] In its more serious form, called periodontitis, the gums can pull away from the tooth, bone can be lost, and the teeth may loosen or fall out. [5] Halitosis (bad breath) may also ...
