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.

Although dental implants are best known as single tooth replacements, they can actually play a role in multiple or complete tooth loss (edentulism) restorations. While replacing multiple teeth with individual implants is quite expensive, there’s another way to incorporate them in a restoration at much less cost — as supports for bridges.
In this case, only a few strategically placed implants are needed to support restorations of multiple crowns fused together into a single unit. Implant-based bridges consist of two main types: the first type is a fixed bridge, which is permanently attached to the implants and can’t be removed by the patient. It’s often the preferred treatment for patients who’ve lost most or all of their teeth but have not yet experienced significant bone loss in the jaw.
This choice, however, may not be the best option for patients with significant bone loss. In these cases, there’s a second type of fixed bridge: an implant-supported fixed denture. This type of fixed denture provides support for the lost bone support of the lips and cheeks. If a fixed bridge is not possible due to finances or inadequate bone support to place 4 to 6 implants, a removable denture (also known as an overdenture) that’s supported and held in place by implants is the next best alternative. Unlike a fixed bridge, an overdenture can be removed by the patient for cleaning purposes, and will require less investment than a fixed bridge.
For people with bone loss, the overdenture does more than restore chewing and speech function. Because bone loss can diminish support of the facial structures — actually shorten the distance between the chin and the tip of the nose — an overdenture provides additional bulk to support these structures to improve appearance. Depending on what the patient needs for facial support, overdentures for the upper jaw can be designed as “full palates,” meaning the denture plastic completely covers the upper jaw palate, or open in which the plastic doesn’t completely cover the palate.
Besides the condition of your teeth, gums and bone, your own personal preferences and financial ability will also play a role in which option is best for you. After considering all these factors, we can recommend which of these types of implant-based restorations will fit your needs. With either bridge, fixed or removable, you’ll certainly benefit from the improvement to both your mouth function and your smile.

Tooth replacement at any age is a challenge, but especially for teenagers. Dental implants in particular may not be possible yet for teens or young adults whose jaws are still developing. Because it’s imbedded directly into bone, the implant will not move with the jaw as jaw growth occurs, making it look potentially unattractive.
The best solution could be a temporary replacement until their jaw reaches maturity. One such option is a removable partial denture (RPD), an artificial tooth set in an acrylic base that resembles gum tissue. Although we associate dentures with older adults, an RPD works well for teens as a temporary measure. Perhaps the best version for a younger person utilizes metal clips that fit over adjacent teeth and hold the RPD in place. Although quite resilient, the wearer needs to be careful when biting into something hard (like an apple or similar firm fruit) or the artificial tooth may break off.
Another option, a bonded bridge, is a fixed solution similar to a traditional bridge. Whereas a traditional bridge is supported by crowns affixed to the teeth on either side of the empty socket (and requiring extensive alteration of the teeth to accommodate them), a bonded bridge attaches to the supporting teeth with wing-like projections of dental material that attaches to the backs of the adjacent teeth, hidden from view. Although not as secure as a traditional bridge, they can conceivably endure until the teen’s jaw structure is ready for an implant or other permanent solution.
Choosing between an RPD and a bonded bridge will depend on a number of factors, including the teen’s individual bite, clenching or biting habits and the health and strength of supporting bone and gums. Regardless of the type of solution chosen, it’s important to maintain good oral hygiene, especially around a bridge. If bacterial plaque is allowed to build up on tooth surfaces, it could result in an infection that can damage both gums and bone, and reduce the chances of a successful implant in the future.
All these and other considerations should be discussed after a thorough examination. From there, we can advise you on the best course of action to restore both appearance and function until it’s time for a permanent restoration.
