Sedation-DentistryCrowns are synthetic caps, usually made of a material like porcelain, placed on the top of a tooth.

Crowns are typically used to restore a tooth’s function and appearance following a restorative procedure such as a root canal. When decay in a tooth has become so advanced that large portions of the tooth must be removed, crowns are often used to restore the tooth.

Crowns are also used to attach bridges, cover implants, prevent a cracked tooth from becoming worse, or an existing filling is in jeopardy of becoming loose or dislocated. Crowns also serve an aesthetic use, and are applied when a discolored or stained tooth needs to be restored to its natural appearance.

veneer_s1Teeth that are badly stained, shaped or crooked may be improved by a veneer placed on the surface of the affected teeth.

Veneers are thin pieces of porcelain or plastic cemented over the front of your teeth to change their color or shape. Veneers are used on teeth with uneven surfaces or are chipped, discolored, oddly shaped, unevenly spaced or crooked. Little or no anesthesia is needed. Veneers have a longer life expectancy and color stability than bonding, and highly resist permanent staining from coffee, tea, or even cigarette smoking.

Veneers are usually made by a dental lab technician working from a model provided by your dentist. Veneers are usually irreversible because it`s necessary to remove a small amount of enamel from your teeth to accommodate the shell.

are your gums in dangerWhitening procedures have effectively restored the smile of people with stained, dull, or discolored teeth.

The darker tissue of your teeth, the dentin, can become exposed as the outer layer of enamel is worn away by the effects of aging or things like caffeine and tobacco.

Food particles are naturally attracted to a tooth’s enamel by a certain protein. Products like coffee and tea, berries and soy sauce are notorious for staining teeth. Over time, teeth actually become more absorbent and vulnerable to staining from food and other substances.

One type of stain—caused by traumatic injuries, medications and fluorosis—actually begins inside the tooth; brushing and flossing don’t help. Another type of stain—one that can be more easily attacked by brushing, flossing and rinsing—is caused by external factors such as foods.

  • Invisalign® has been proven effective in clinical research and in orthodontic practices nationwide.

Restortaive-Dentistry_s1Root canals are tiny passageways that branch off from beneath the top of the tooth, coursing their way vertically downward, until they reach the tip of the root.

All teeth have between one and four root canals.

Many tooth problems involve infections that spread to the pulp, which is the inner chamber of the tooth containing blood vessels, nerves and other tissues. When the infection becomes worse, it can begin affecting the roots. A traumatic injury to a tooth can also compromise the pulp, leading to similar problems.

A diseased inner tooth brings a host of problems including pain and sensitivity as the first indications of a problem.  However, inside a spreading infection can cause small pockets of pus to develop, which can lead to an abscess.

Tooth pain_s1Simple toothaches can often be relieved by rinsing the mouth to clear it of debris and other matter. Sometimes, a toothache can be caused or aggravated by a piece of debris lodged between the tooth and another tooth. Avoid placing an aspirin between your tooth and gum to relieve pain, because the dissolving aspirin can actually harm your gum tissue.
Before development of dental implants, dentures were the only alternative to replacing a missing tooth or teeth.

Implants are synthetic structures that are placed in the area of the tooth normally occupied by the root. Implants are anchored to the jawbone or metal framework on the bone and act as a foundation for an artificial tooth or permanent bridge. In some cases, implants can be used to attach dentures.

Not everyone is a candidate for a dental implant, however. For a successful implant to take hold, a candidate must have proper bone density and have a strong immune system. In all cases, dental implants require strict oral hygiene.

A knocked out tooth or bitten tongue can cause panic in any parent, but quick thinking and staying calm are the best ways to approach such common dental emergencies and prevent additional unnecessary damage and costly dental restoration. This includes taking measures such as application of cold compresses to reduce swelling, and of course, contacting our office as soon as possible.
