Porcelain Veneers Dramatically Improves Your Smile at a London dentist

Thursday, September 11th, 2008

Porcelain veneers are being widely used by London-based dentists and have been available for many years throughout the world. Teeth that are uneven, discoloured, worn and/or damaged may be corrected with the use of porcelain veneers. Porcelain veneers, also referred to as dental veneers and laminates, are thin porcelain coverings fabricated distinctively for each individual patient and tooth. They provide an excellent cosmetic result in the properly chosen situation. Porcelain veneer technique(s) involve minimal preparation of the tooth enamel (the outer shell of the tooth), and at times the dentin (substructure of the tooth that can be sensitive to tooth preparation). This depends on the misalignment of the teeth, and the result sought by both you and your dentist.
The porcelain veneer procedure usually takes two dental visits. During your first visit, a smile analysis is performed either by using a camera or a cast of your mouth, or both. The result that can be obtained is usually shown to you via computer or by wax being placed on the stone model of your teeth. Any changes to colour, form and function of your teeth should be discussed with your dentist at this time. Once you and your dentist have agreed on the result that can be obtained, your anterior (i.e., front) dentition (i.e., teeth) are prepared using a diamond bur with local anaesthesia or no anaesthesia. This will depend on the amount of tooth structure that needs to be removed for the desired result.
Temporary acrylic or composite shells are fabricated by your dentist or his in-house laboratory to prevent tooth sensitively and the inadvertent shift of your teeth until the delivery visit. Impressions are taken of your mouth, and the stone models are sent to a laboratory that specializes in porcelain veneer fabrication. Upon return for your insertion visit, the porcelain veneers are bonded in place on your teeth utilizing the special materials to firmly affix the thin porcelain shell to each tooth. Porcelain veneers are inherently delicate; however, when securely bonded to the well-built tooth substructure they become both physically strong and long-lasting.
The greatest advantage of veneers above other aesthetic former brands are that porcelain veneers created to copy and achieve an extremely realistic look, and depending upon the artistic nature of the laboratory that fabricates the porcelain veneers and the artistry of the dentist placing the veneers, stunning results can be achieved. The best results are to both imitate the natural translucency of the tooth enamel and to also achieve the colour changes that are expected by the patient using opaque bonding materials and additional intrinsic colouring if required. Since Londoner’s generally have darker teeth, this intrinsic staining and use of opaque bonding materials should be carefully evaluated. After being placed and bonded, the porcelain veneers should very closely resemble the outer look of tooth enamel. A great advantage of porcelain veneers over composite bonding materials are their resistance to staining and discolouration.

Dentin Hypersensitivity In London Dental Patients

Wednesday, August 27th, 2008

Having sensitive teeth is something most of us have experienced. It is so common that many of the patients in London and around the world make toothpaste for sensitive teeth their brand of choice. Dentists in London report that the complaint they hear the most is that of patient’s teeth being very sensitive. It was found that one in five adults have some sort of tooth sensitivity.
Those who have sensitive teeth know that when something hot, cold, sweet, or sour is felt by the teeth, it gives off a sharp pain. It does not last long but the intensity of it is enough to make one stop and take notice. Some individuals have teeth that are so sensitive; a puff of cold air to the mouth will cause the pain to occur.
Most sensitivity of the teeth is a result of the enamel coating on the outside of the teeth being worn down. This enamel is the covering for the dentin and when it is gone, the pain occurs. This sensitivity can also be a result of someone who grinds their teeth, has missing fillings, has a tooth which has been cracked, disease of the gums, receding gums, plaque on the teeth, abrasive brushing, whitening of the teeth, eating foods that are acidic.
If the sensitivity gets worse, you should see a dentist who can help diagnose the problem and find ways to help the condition. They have a treatment known as iontophoresis that applies fluoride to the tooth through electrical currents to help the problem.
