Implants

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

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.

Crowns

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.

Diastema

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.

Whitening

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.

Root Canal

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.

 

 

 

 

 

There are times when a tooth suffers damage (from decay, for example) that is too extensive to be treated with a simple filling — but not extensive enough to need a full-coverage crown. In these cases, the best option for restoring the tooth may be an inlay or onlay.

Inlay, Onlays and Crowns.

Both inlays and onlays are considered “indirect” fillings, meaning that they are fabricated outside the mouth (generally at a dental laboratory), and then bonded to the tooth by the dentist. This is in contrast to a “direct” filling, which is applied directly to the cavity by the dentist in one office visit.

An indirect filling is considered an “inlay” when it fits within the little points or “cusps” of a back (premolar or molar) tooth. It is an “onlay” if it covers one or more of these cusps. Either way, the procedure for placing an inlay or onlay is the same.

How It Works

Getting an inlay or onlay is very much like what you would experience having a crown placed, with one important distinction: less of your natural tooth structure will need to be removed by drilling when you receive an inlay or onlay. When you get a crown, the tooth needs to undergo significant reshaping so that it will fit inside its new covering. Since dentistry's goal is to preserve as much of your natural tooth structure as possible, inlays and onlays may be recommended instead of crowns when a tooth can be restored with this more conservative type of treatment.

The first steps in getting an inlay or onlay are numbing the tooth and surrounding area with a local anesthetic, and then removing the decay. This is done in order to prevent the decay, which is actually a type of infection, from progressing deeper into the tooth.

Once the tooth has been prepared, an impression of it is made (either digitally or with a putty-like material) and sent to the dental laboratory. There, the impression is used to make a model of your tooth for the creation of your inlay/onlay. The final restoration can be made out of gold or a tooth-colored ceramic or resin.

Before you leave the office, a temporary filling will be attached to your tooth to protect it until the permanent restoration is ready. At your second visit, the permanent inlay/onlay will be attached to your tooth with either a resin that hardens when exposed to a special light source, or a type of permanent cement.

Inlays and onlays are strong, long-lasting, and require no greater level of care than any other tooth. Conscientious daily brushing and flossing, and regular professional cleanings at the dental office are all you need to make sure your restoration lasts for years to come.
