Bad breath, bleeding gums, pain when chewing and moderate bone loss are also hallmarks of this stage. Advanced periodontitis: This is the most severe stage and a major cause of tooth loss in adults.
A 2006 Zogby International poll of 2,590 US adults found that 72% of respondents were not aware that mercury was a main component of dental amalgam and 92% of respondents would prefer to be told about mercury in dental amalgam before receiving it as a filling. [85]
As the dental dam clamp is placed along the gum line, this can cause some discomfort or pain (especially in a patient who does not require local anaesthesia), bleeding from the gums, damage to the periodontal ligament or abrasion of the cementum on the root of the tooth, which may cause an uneven surface on the tooth root that can retain plaque ...
It is a very thin, black-blue line visible along the margin of the gums, at the base of the teeth. [1] [2] It is caused by the reaction between circulating lead and sulphur ions produced by oral bacteria, forming deposits of lead sulfide in the gums. [3] The sign was described in 1840 by Henry Burton: [4]
The main features are painful, bleeding gums, and ulceration of interdental papillae (the sections of gum between adjacent teeth). This disease, along with necrotizing periodontitis (NP) and necrotizing stomatitis, is classified as a necrotizing periodontal disease , one of the three general types of gum disease caused by inflammation of the ...
Gingival recession, also known as gum recession and receding gums, is the exposure in the roots of the teeth caused by a loss of gum tissue and/or retraction of the gingival margin from the crown of the teeth. [1] Gum recession is a common problem in adults over the age of 40, but it may also occur starting in adolescence, or around the age of 10.
Back teeth showing fissure system. Dental caries is an upset of the balance between loss and gain of minerals from a tooth surface. [3] The loss of minerals from the teeth occurs from the bacteria within the mouth, fermenting foods and producing acids, whereas the tooth gains minerals from our saliva and fluoride that is present within the mouth.

Versatility: Composite fillings can be used to repair chipped, broken or worn teeth [18] which would not be repairable using amalgam fillings. Repairability: In many cases of minor damage to a composite filling, the damage can be easily repaired by adding additional composite. An amalgam filling might require complete replacement.
