Dentures, removable restorations for missing teeth and gum tissue, can take a number of different forms, but are usually of two different types: complete and partial. A complete denture replaces all the teeth in a given arch. A removable partial denture (RPD), on the other hand, replaces several missing teeth while using the remaining teeth as support.
A common type of RPD formed of plastic is known as a “flipper” because it’s lightweight enough to be “flipped out” or moved around with the tongue. They serve an important purpose as a temporary appliance for use between periodontal treatment, implant placement and similar treatments before obtaining a more permanent restoration. In fact, they’re often referred to as “transitional” RPDs because they’re not designed for permanent tooth replacement.
Because of their low cost relative to other restorations, however, they often become the permanent choice for many people. While a well-constructed, properly fitting RPD in a healthy mouth can be an affordable alternative for people on modest budgets, their long-term use may increase the risk of dental disease and accelerated bone loss. Decades of research verify that people who permanently wear RPDs encounter more tooth decay and periodontal (gum) disease than non-wearers.
This is because the attachment points of a plastic RPD to remaining teeth increases bacterial growth, which can cause both tooth decay and gum disease. This doesn’t only endanger the survival of the remaining teeth, it can lead to bone loss that will affect the RPD’s fit.
While the better course is to consider RPDs as a stepping stone to dental implants or a fixed bridge, there’s an intermediary RPD constructed of cast vitallium or gold alloy that could be considered a permanent choice. These are even lighter weight than plastic and less obtrusive in their attachments in the mouth, which can reduce plaque stagnation and promote a better oral environment.
Regardless of your choice in dentures, it’s always important to maintain good consistent oral hygiene with daily brushing and flossing and semi-annual professional cleanings and checkups. Keeping a healthy mouth will help reduce your risk of dental disease and increase your satisfaction with your denture of choice.

You’ve suddenly noticed one of your teeth looks and feels uneven, and it may even appear chipped. To make matters worse it’s right in front in the “smile zone” — when you smile, everyone else will notice it too. You want to have it repaired.
So, what will it be — a porcelain veneer or crown? Maybe neither: after examining it, your dentist may recommend another option you might even be able to undergo that very day — and walk out with a restored tooth.
This technique uses dental materials called composite resins. These are blends of materials that can mimic the color and texture of tooth structure while also possessing the necessary strength to endure forces generated by biting and chewing. A good part of that strength comes from the way we’re able to bond the material to both the tooth’s outer enamel and underlying dentin, which together make up the main body of tooth structure. In skilled, artistic hands composite resins can be used effectively in a number of situations to restore a tooth to normal appearance.
While veneers or crowns also produce excellent results in this regard, they require a fair amount of tooth alteration to accommodate them. Your dentist will also need an outside dental laboratory to fabricate them, a procedure that could take several weeks. In contrast, a composite resin restoration usually requires much less tooth preparation and can be performed in the dental office in just one visit.
Composite resins won’t work in every situation — the better approach could in fact be a veneer or crown. But for slight chips or other minor defects, composite resin could transform your tooth’s appearance dramatically.
To see if composite resin is a viable restoration option for your tooth, visit your dentist for a complete dental examination. It’s quite possible you’ll leave with a more attractive tooth and a more confident smile.

Although periodontal (gum) disease usually affects your gums first, your teeth may eventually suffer. That’s because the disease can damage both attaching gum tissues and supporting bone.
One advanced sign of this is when one or more teeth become loose. A loose tooth is an alarm bell that you’re about to lose it.
Fortunately, we can often treat loose diseased teeth with a two-phase approach. First and foremost, we need to bring the gum infection under control by removing plaque and calculus (tartar) — the “fuel” for the infection — from all tooth and gum surfaces. Depending on how extensive it is, we have options: we can use specially designed hand instruments to remove plaque and calculus, ultrasonic equipment that loosens and flushes plaque and calculus away, or, if necessary, conventional or laser surgery.
Depending on the extent of the infection, in some cases we may need to use regenerative surgical techniques like gum and bone grafting to replace lost tissue. Healing takes time, though, which leads to the second phase of treatment — securing the loose tooth during gum healing.
The most common way is through a bite adjustment, where teeth are altered to equilibrate chewing forces evenly. This results in all the teeth being hit at the same time allowing the loose teeth to heal and tighten up.
Another option is splinting teeth together. Although there are different methods, the basic idea is to join the loose teeth with stable teeth like pickets in a fence. One way is to bond splinting material across the back surfaces of the involved teeth. Another way is to cut in a small channel across the teeth and insert and bond a rigid strip of metal to splint the teeth in place.
The splint is usually a temporary measure while the gums heal. In some situations, though, we may need to perform a permanent splint by crowning the affected teeth and then splinting the crowns together. If you have a grinding habit we may also prescribe a night guard to limit the damage done while you sleep.
Before deciding on which technique is best for you, we would first need to evaluate the health of the affected teeth to see whether the effort would be worth it. It could be the tooth’s supporting bone structure has become so deteriorated that it might be better to extract the tooth and consider an implant or other replacement. First, though, we would attempt if at all practical to save the tooth — and the sooner we begin treating it, the better your chances for such an outcome.
