Considering the costs, many people view replacing a back tooth as less important than a more visible front tooth. They’re rarely seen, so who will notice?
You might, eventually. A missing back tooth can set off a chain reaction of problems that can affect your overall dental health. Besides playing an important role in chewing food, back teeth also redistribute most of the chewing force away from the front teeth. Their absence can also affect the bite: adjacent teeth to the missing one will tend to migrate toward the open space, causing them to tip and rotate into an improper position. This can cause an increase in tooth mobility, excessive wear and erosion, and endanger their survival in the long run.
To avoid these and other problems you should consider some form of replacement. Most dentists prefer a dental implant for its life-like appearance and durability, and because its titanium post has a natural affinity with bone. Bone cells will grow around and permanently adhere to the implant, which may stop and even reverse bone loss in some cases.
Implants, though, require a certain amount of bone structure initially to anchor and position properly. If you have inadequate bone and don’t want to bone graft the area, the next best option is a fixed bridge, in which the missing tooth is replaced with an artificial crown known as a pontic. The pontic is fused between two support crowns that are permanently affixed to the natural teeth on either side of the missing tooth (also known as abutments). While fixed bridges restore function and inhibit tooth migration, they require the natural tooth supporting the bridge to be reduced to accommodate the crowns placed on them. This permanently alters them and places them at higher risk for future nerve damage, gum disease and decay.
One final option is a removable partial denture (RPD). Although RPDs restore function and improve appearance, their movement within the mouth may place additional stress on the teeth that hold them in place. This movement over time could damage or loosen them.
We can discuss which option is best for you after a complete dental exam. The important thing, though, is to replace the back tooth as soon as possible — doing nothing could cost you much more in the long run.

Want to know the exact wrong way to pry open a stubborn lid? Just ask Jimmy Fallon, host of NBC-TV’s popular “Tonight Show.” When the 40-year-old funnyman had trouble opening a tube of scar tissue repair gel with his hands, he decided to try using his teeth.
What happened next wasn’t funny: Attempting to remove the cap, Fallon chipped his front tooth, adding another medical problem to the serious finger injury he suffered a few weeks before (the same wound he was trying to take care of with the gel). If there’s a moral to this story, it might be this: Use the right tool for the job… and that tool isn’t your teeth!
Yet Fallon is hardly alone in his dilemma. According to the American Association of Endodontists, chipped teeth account for the majority of dental injuries. Fortunately, modern dentistry offers a number of great ways to restore damaged teeth.
If the chip is relatively small, it’s often possible to fix it with cosmetic bonding. In this procedure, tough, natural-looking resin is used to fill in the part of the tooth that has been lost. Built up layer by layer, the composite resin is cured with a special light until it’s hard, shiny… and difficult to tell from your natural teeth. Best of all, cosmetic bonding can often be done in one office visit, with little or no discomfort. It can last for up to ten years, so it’s great for kids who may be getting more permanent repairs later.
For larger chips or cracks, veneers or crowns may be suggested. Veneers are wafer-thin porcelain coverings that go over the entire front surface of one or more teeth. They can be used to repair minor to moderate defects, such as chips, discolorations, or spacing irregularities. They can also give you the “Hollywood white” smile you’ve seen on many celebrities.
Veneers are generally custom-made in a lab, and require more than one office visit. Because a small amount of tooth structure must be removed in order to put them in place, veneers are considered an irreversible treatment. But durable and long-lasting veneers are the restorations of choice for many people.
Crowns (also called caps) are used when even more of the tooth structure is missing. They can replace the entire visible part of the tooth, as long as the tooth’s roots remain viable. Crowns, like veneers, are custom-fabricated to match your teeth in size, shape and color; they are generally made in a dental lab and require more than one office visit. However, teeth restored with crowns function well, look natural, and can last for many years.
So what happened to Jimmy Fallon? We aren’t sure which restoration he received… but we do know that he was back on TV the same night, flashing a big smile.

The various structures in your mouth — your teeth and gums, of course, as well as periodontal tissues that hold teeth in place within the jaw — all function together to create your smile. This includes muscles like the frenum, a fold of muscle tissue that connects the gums to the upper lip, which helps pull the lip upward when you smile.
Unfortunately, an overly large frenum could contribute to an unattractive space between your two upper front teeth. The problem occurs when the frenum grows beyond its normal range and runs between the front teeth to connect with the gums behind them at the forefront of the roof of your mouth. The resulting space that may develop can be closed with orthodontics, but unless the excess frenum tissue is addressed the space may eventually reopen.
The frenum is just one cause among many for a noticeably wide space, including bite problems (malocclusions), finger-sucking habits or missing teeth. We would, therefore, need to examine your mouth to determine the exact cause before beginning any treatment. If indeed the frenum is the source of the problem, it will be necessary to ultimately remove the excess portion through a procedure known as a frenectomy.
A frenectomy is a minor surgical procedure performed by a periodontist, oral surgeon or a general dentist with surgical training. After numbing the area with local anesthesia, the tissue behind the teeth is dissected or reduced in size with a small scalpel or a surgical laser. The wound is then closed with a few stitches; any post-surgical discomfort is usually minimal and managed with non-steroidal anti-inflammatory pain medication. The wound will completely heal within a few weeks.
Most frenectomies are performed after orthodontics to close the space. Removing it prior to tooth movement may result in scar tissue that prevents the space from closing. It’s also easier for the surgeon to gauge how much tissue to remove after space closure to avoid removing too much, which can leave a “black” triangular hole where gum tissue should normally be.
Treating an abnormally large frenum isn’t difficult, but it needs to be coordinated with orthodontic treatment for the best outcome. The end result is a smile that’s both healthy and attractive.
