Bridges
A bridge may be used to replace missing teeth, help maintain the shape of your face, and alleviate stress on your bite.
A bridge replaces missing teeth with artificial teeth, looks great, and literally bridges the gap where one or more teeth may have been. Your bridge can be made from gold, alloys, porcelain, or a combination of these materials, and is bonded onto surrounding teeth for support.
The success of any bridge depends on its foundation — the other teeth, gums, or bone to which it is attached. Therefore, it's very important to keep your existing teeth, gums, and jaw healthy and strong.
Crowns
Crowns are a cosmetic restoration used to strengthen a tooth or improve its shape. Crowns are most often used for teeth that are broken, worn, or partially destroyed by tooth decay.
Crowns are "cemented" onto an existing tooth and fully cover the portion of your tooth above the gum line. In effect, the crown becomes your tooth's new outer surface. Crowns can be made of porcelain, metal, or both. Porcelain crowns are most often preferred because they mimic the translucency of natural teeth and are very strong.
Crowns or onlays (partial crowns) are needed when there is insufficient tooth strength remaining to hold a filling. Unlike fillings which apply the restorative material directly into your mouth, a crown is fabricated away from your mouth. Your crown is created in a lab from your unique tooth impression which allows a dental laboratory technician to examine all aspects of your bite and jaw movements. Your crown is then sculpted just for you so that your bite and jaw movements function normally once the crown is placed.
Fillings
Traditional dental restoratives, or fillings, are most often made of silver amalgam. The strength and durability of this traditional dental material makes it useful for situations where restored teeth must withstand extreme forces that result from chewing, often in the back of the mouth.
Newer dental fillings include ceramic and plastic compounds that mimic the appearance of natural teeth. These compounds, often called composite resins, are usually used on the front teeth where a natural appearance is important, but they can also be used on the back teeth depending on the location and extent of the tooth decay.
What’s right for me?
Several factors influence the performance, durability, longevity, and expense of dental restorations, including:
- The components used in the filling material
- The amount of tooth structure remaining
- Where and how the filling is placed
- The chewing load that the tooth will have to bear
- The length and number of visits needed to prepare and adjust the restored tooth
Before your treatment begins, your doctor will discuss with you all of your options and help you choose the best filling for your particular case. In preparation for this discussion it may be helpful to understand the two basic types of dental fillings — direct and indirect.
- Direct fillings are fillings placed into a prepared cavity in a single visit. They include silver amalgam, glass ionomers, resin ionomers, and composite (resin) fillings. The dentist prepares the tooth, places the filling, and adjusts it in one appointment.
- Indirect fillings generally require two or more visits. They include inlays, onlays, and veneers fabricated with gold, base metal alloys, ceramics, or composites. They are used when a tooth has too much damage to support a filling but not enough to necessitate a crown. During the first visit, the dentist prepares the tooth and makes an impression of the area to be restored. The dentist then places a temporary covering over the prepared tooth. The impression is sent to a dental laboratory, which creates the dental restoration. At the next appointment, the dentist cements the restoration into the prepared cavity and adjusts it as needed.
Implant Restoration
If you’ve lost a tooth, your dentist may have recommended getting a dental implant to fill the empty space and allow for optimal function of your teeth. The dental implant itself is only a replacement for the root of the lost tooth, so after the implant has been placed, you’ll still need to get a restoration, or replacement tooth. Implants provide a strong foundation for fixed (permanent) or removable replacement teeth that are made to match your natural teeth.
To make the new tooth or teeth, your dentist will make an impression of your existing teeth, creating a model of your bite. The new restoration, most typically a crown, will be based on this model so it will blend in perfectly with the rest of your teeth. The crown is then attached to the connector point (abutment) on your implant.
Replacing a lost tooth is essential to a healthy mouth and a healthy body. It will provide you with increased aesthetics of course, but will also improve your speech, ease of eating, and oral hygiene.
