Dental Crowns Can Protect Damaged Teeth

Posted in Cosmetic Dentistry,Dental Emergencies by UK Dental Tourism on April 24, 2010

Teeth can be damaged in many ways. Chips, cracks and breaks can occur as the result of sporting injury, motor vehicle accidents or from any other kind of head trauma. Broken teeth can be very painful and also expose the sensitive inside parts of the tooth to the risk of infection and disease. Teeth can also be damaged by dental decay and enamel erosion. This again leaves them vulnerable to attack from disease, which could eventually lead to tooth loss. When teeth are damaged in this way it is necessary to protect them from further injury and also to restore the cosmetic appearance.

One of the oldest and most effective ways of protecting teeth is to fit a dental crown over the top. A dental crown is a ceramic or metal and ceramic cap that is designed to fit over the damaged tooth, covering all parts of the tooth above the gum line to act as a barrier to further damage. A  dentist will first need to remove some of the existing enamel so that the crown can fit comfortably over the top. The crown, which will have been made in laboratory conditions to be the same size and shape as the original tooth, will then be cemented over the top using composite bonding.

Crowns are made from metal and ceramic as these are very versatile and strong materials. Ceramics such as porcelain also have a very similar appearance to tooth enamel, giving an improved aesthetic appearance. Once firmly in place the crown will perform all the functions of the original tooth.Crowns are also used after certain dental surgeries and treatments to add a dimension of protection to the teeth.

Dental crowns are commonly manufactured from porcelain, a type of ceramic with a similar consistency and appearance to tooth enamel. Modern crowns are increasingly fabricated using the latest computer-aided technology.CEREC technology now have revolutionized dental restorations.CEREC is a state-of-the-art dental restoration product that has allowed dentists to use computer-aided technology to produce ceramic inlays and crowns. Utilizing new technologies such as 3D imaging, digital x-rays and CAD/CAM, CEREC has allowed teeth restorations to be carried out in only a single visit to a  dentist rather than taking several appointments.CEREC works by creating a digital three-dimensional image of the patient’s mouth that can be stored on a computer.
CEREC technology also limits the need for enamel removal because of the increased degrees of accuracy involved using computer-guided technology.

CEREC is most commonly used to manufacture dental crowns and filling inlays to repair teeth that have been damaged by dental trauma or tooth decay. The ceramic restorations are firmly secured to the teeth with composite resin bonding creating a solid and resilient shield against any further damage to the damaged tooth.Dental crowns are very versatile and useful dental tools that can prevent the need for further treatment. Patients with damaged teeth should make an appointment with a  dentist to discuss the benefits of dental crowns.

Emergency Treatment For Knocked Out Tooth

A knocked out, or avulsed tooth as it is known in the dentistry profession, can be caused by any kind of accident but the most common involve sports injuries, car accidents, fighting and chewing on hard food. A knocked out tooth can be quite serious so dentists advise that prevention is always better than cure.

When playing sports, especially physically demanding ones, it is important to wear a mouth guard. They may be uncomfortable and make it difficult to talk but these are minor considerations compared to the pain and lifetime of embarrassment a knocked out tooth can cause. Always wear a seatbelt when traveling in a car, avoid eating hard foods such as bones and, needless to say, don’t get involve in any fights.

If you are unfortunate enough to have a tooth knocked out, then the first thing to do is to try and replace it immediately. Being careful not to touch the tooth by its root i.e holding the biting edge, simply put it back in its place. With any luck it will slot right back in and can be held in place gently by wet gauze or a tea bag. Do not apply significant pressure or attempt to force it if it won’t go.

If the tooth won’t slot back in, the next best thing is to keep it in an air tight container and cover it with milk or saliva. This may preserve it long enough to save it and have it replaced.The most optimum storage media that are available have been shown to be pH balanced cell preserving solutions. The best known and most extensively tested is called Hank’s Balanced Salt Solution (HBSS). It has all of the metabolites such as Ca, P04, K+ and glucose that are necessary to maintain normal cell metabolism for long periods of time. HBSS has been extensively tested in dental and medical research for the past twenty years. This research has shown that 90% of cells stored in HBSS for 24 hours maintain their normal viability and after four days, still have 70%viable.

It is important you always see a dentist immediately when you have a tooth knocked out or fractured. Your dentist will be on hand to help in an emergency and will do all they can to save the original tooth. If this is not possible they will be able to offer the best advice about the next course of action, which is likely to involve a dental bridge.
