Firstly the tooth surface is thoroughly cleaned with a paste and rotating brush by your dentist or hygienist. Next the tooth is washed with water and dried. Then a solution that is acidic is placed on the fissured area of the tooth's chewing surface for a number of seconds before being rinsed off. This creates small microscopic areas and a fine rougher surface than the surrounding tooth enamel, that can be seen with a microscope. The rough surface and microscopic areas enable the dental sealant to attach to the tooth. After the tooth is dried again, the liquid dental sealant is placed on the tooth and hardened. Dental sealants are hardened by using a light that hardens the dental sealant, or sometimes by using a two-component dental sealant that sets without using a light. Once the dental sealant has hardened it becomes a hard plastic varnish coating, and you can chew on the tooth again.
Dental sealants can be clear, white or have a slight tint depending upon the dental sealant used.
Yes — while less common, dental sealants are sometimes placed in adults at risk for caries, on deep grooves and fissures that do not already have fillings or dental sealants.
Dental sealants have been used and have been proven to be effective since the 1970s. Many studies have shown that they are effective in helping to prevent decay on chewing (occlusal) surfaces. Dental sealants can last many years. If necessary, it is also possible to place a new dental sealant on the tooth.
Yes. Dental sealants only protect the surface area that they are placed on. Fluoride helps protect all the surfaces of the tooth from decay and cavities.
Plaque is a clear sticky film of bacteria that constantly forms on teeth. As plaque collects it forms a hard layer of tartar (or calculus) particularly in hard to reach areas between teeth and near the gumline.
Bacteria found in plaque create toxic chemicals that irritate the gums. Eventually these bacteria cause the underlying bone around the teeth to be destroyed, a condition known as gum disease. Recent research suggests that gum disease is linked to other health problems including heart disease, stroke, pneumonia and some pregnancy complications.
Removal of plaque with brushing and flossing on a twice daily basis and removal of tartar by your dentist and dental hygienist is the first step in defeating gum disease. By the time gum disease begins to hurt, it may be too late. Seeing a dentist regularly can help prevent this and many other problems.
If a manual toothbrush is used for the appropriate amount of time, and done with proper technique, it can perform just as well as a powered toothbrush. But many people don't brush for the recommended two to three minutes. Children are also good candidates for powered brushes as their brushing habits tend to be less than optimal. While everyone certainly does not need an electric toothbrush, in many instances they can be beneficial. Ask your dentist if you have any questions about which brush is best for you.
While bad breath (or "halitosis") can be linked to numerous systemic diseases, the majority of bad breath originates in the mouth. A dry mouth or a low salivary flow can also influence bad odor.
There are two main goals in the management of bad breath. First, controlling the bacteria that produce the sulfur compounds and second, to neutralize the sulfur compounds that are produced.
