Dental implants are a popular and effective way to replace missing teeth and are designed to blend in with your other teeth. They are an excellent long-term option for restoring your smile. In fact, the development and use of implants is one of the biggest advances in dentistry in the past 40 years. Dental implants are made up of titanium and other materials that are compatible with the human body. They are posts that are surgically placed in the upper or lower jaw, where they function as a sturdy anchor for replacement teeth.
Veneers are thin, custom-made shells crafted of tooth-colored materials designed to cover the front side of teeth. They are an option for correcting stained, chipped, decayed or crooked teeth. Veneers are made by a dental technician, usually in a dental lab, working from a model provided by your dentist. Placing veneers is usually an irreversible process, because it's necessary to remove a small amount of enamel from your tooth to accommodate the shell. Your dentist may recommend that you avoid some foods and beverages that may stain or discolor your veneers such as coffee, tea or red wine. Sometimes a veneer might chip or fracture. But for many people the results are more than worth it.
A crown can help strengthen a tooth with a large filling when there isn’t enough tooth remaining to hold the filling. Crowns can also be used to attach bridges, protect a weak tooth from breaking or restore one that’s already broken. A crown is a good way to cover teeth that are discolored or badly shaped. It’s also used to cover a dental implant.
A diastema is an area of extra space between two or more teeth. The two front teeth of the upper jaw area is where diastema is most frequently seen. Many children experience diastema as primary teeth fall out, though in most cases these spaces close when the permanent teeth erupt.
Diastemas may also be caused by a tooth size discrepancy, missing teeth or an oversized labial frenum, the tissue that extends from the inside of the lip to the gum tissue where the upper two front teeth are located. Secondary reasons involve oral alignment issues such as an overjet or protrusion of the teeth.
Teeth whitening is a simple process. Whitening products contain one of two tooth bleaches (hydrogen peroxide or carbamide peroxide). These bleaches break stains into smaller pieces, which makes the color less concentrated and your teeth brighter.
Does Whitening Work on All Teeth?
No, which is why it’s important to talk to your dentist before deciding to whiten your teeth, as whiteners may not correct all types of discoloration. For example, yellow teeth will probably bleach well, brown teeth may not respond as well and teeth with gray tones may not bleach at all. Whitening will not work on veneers, crowns or fillings. It also won’t be effective if your tooth discoloration is caused by medications or a tooth injury.
If you have a severely damaged, decaying tooth or a serious tooth infection (abscess), your dentist may recommend a root canal treatment. Root canals are used to repair and save your tooth instead of removing it.
A tooth that has been structurally damaged by decay or trauma sometimes needs to be crowned or “capped” so that it can look good and function properly again. A crown is a durable covering that is custom-made to fit over the entire tooth from the gum line up. Crown fabrication traditionally takes place in a dental laboratory. But these days, there's a much more convenient alternative: same-day crowns made in the dental office.
Advanced dental technology known as Computer-Aided Design/Computer-Aided Manufacturing, or CAD/CAM, makes it possible to fabricate laboratory-grade crowns and other dental restorations in minutes. It's an amazing innovation when you consider that traditionally, crowns take two or three visits and just as many weeks of waiting. Now you can have a restored tooth without the wait.
Best of all, studies have shown that CAD/CAM tooth restorations are just as successful as crowns made with traditional materials and techniques. And the amazingly lifelike appearance of a same-day crown means that no one will know your tooth has been restored.
How It Works
The process of crowning a tooth starts out the same way, whether it's a same-day crown or traditional crown: with “preparation” of the tooth. This involves removing any decay that's present, and shaping the tooth with a dental drill so that it will fit perfectly inside the crown. But the similarities end there.
If you were getting a traditional crown, the next step would be to take an impression (mold) of your teeth with a putty-like material, and use it to construct a model on which to create the crown. With a same-day crown, your teeth are simply given a light dusting of reflective powder and then a small scanning wand attached to a computer is used to take digital pictures inside your mouth. In seconds, the computer will generate a highly accurate 3D model of your teeth. But it gets even better.
With the help of the CAD/CAM software, your crown will be designed while you wait. The software can even be used to create a mirror-image twin of the same tooth on the other side of your mouth, for the most natural-looking result possible. Then a block of dental ceramic material is chosen in the shade that most closely matches your own teeth. The computer's digital design is transmitted to a milling machine that carves the crown from the ceramic block in about five minutes.
Once the crown's fit has been verified, and any necessary aesthetic enhancements have been made to the crown's surface (staining and glazing, for example), the crown will be bonded to your tooth. With a traditional crown, you would have to wear a temporary restoration for several weeks while the permanent crown was being fabricated at the lab. With a same-day crown, you walk out with the real thing.
Caring for Your Same-Day Crown
Crowned teeth require the same conscientious care as your natural teeth. Be sure to brush and floss between all of your teeth — restored and natural — every day to reduce the build-up of dental plaque. When you have crowns, it is even more important to maintain your regular schedule of professional cleanings at the dental office. Avoid using your teeth as tools (to open packages, for example). If you have a grinding habit, wearing a nightguard would be a good idea to protect your teeth and your investment. A well-cared-for same-day crown will last for years to come.
Creating In-Office Dental Restorations With Computers Once upon a time, dentists — and patients — needed to wait weeks for a dental laboratory to make crowns and other dental restorations. Now, with an exciting digital technology known as Computer-Aided Design/Computer-Aided Manufacturing (CAD/CAM), some dentists are fabricating high-quality restorations themselves right in their own offices — in minutes...
