LookattheLong-TermCostsWhenConsideringDentalImplants

You’ve probably heard a lot of great things about dental implants as a replacement for missing teeth. But there’s one aspect about implants that may cause you hesitation about choosing them: the cost. If you have multiple teeth to be replaced, the expense of implants may seem even further beyond your means.

But before you decide against what’s widely considered the premier tooth replacement option, it would be beneficial for you to look at their cost from a long-term perspective. You may find implants are actually a cost-effective investment in both your oral health and your smile.

So, what sets the dental implant apart from other options? One of its most important attributes is its life-like appearance. Not only does the visible crown resemble the color, shape and texture of natural teeth, the implant’s placement can so precisely mimic the appearance of natural teeth emerging from the gums, it’s indistinguishable from the real thing.

They’re not just attractive, but also durable. This is due in large part to titanium, the most common metal used in implants, which has the unique quality of being osseophilic, or “bone-loving.” Bone cells naturally attract to titanium and over time will grow and adhere to the implant in a process known as osseointegration. As a result, the implant’s attachment in the jaw becomes strong and secure.

This durability gives implants a greater longevity on average than most other replacement options. If you thus compare the total costs for an implant (including maintenance) over its projected life with the costs of other options like dentures or fixed bridges, you’ll find implants may actually cost less over time.

That may sound affordable for one or two missing teeth — but what about several? Replacing multiple teeth individually with implants can be quite high; but implants are also versatile — just a few strategically placed implants can support a fixed bridge or overdenture. This “hybrid” solution combines the affordability of these other options with the stability of implants.

Before weighing your options, you should first undergo a complete dental examination to see if you’re a candidate for implants. From there we can help you decide whether implants are the right investment for your health and your smile.

WemayNeedtoBuilduptheBoneinYourJawbeforeImplants

Dental implant technology has advanced at such an astounding rate in recent years that you can now walk into a dentist's office with a problem tooth and out the same day with a new one. Unfortunately, not all dental situations allow for this possibility.

For example, you might be considering an implant many years after losing a tooth. But there's a potential problem: there might not be enough supporting bone. While an implant might still be possible, inadequate bone complicates the matter.

Because implants are essentially tooth root replacements, they require a certain amount of bone for stability and the best attractive outcome. As a general rule, implants need to be surrounded by  at least 1.5-2.0 millimeters of healthy bone to support an implant. But you might not have enough if your tooth has been missing for awhile, regardless if you have or haven't worn dentures or other restorations.

That's because bone has a life cycle in which older cells die and newer ones form to take their place. As we chew or bite, the force generated travels up through the teeth to the bone to stimulate this new growth. Without a tooth the bone doesn't receive this stimulus, which can slow the growth rate. Over time the affected bone can lose its volume and density.

If we find you've experienced loss to the point your bone won't support an implant, that doesn't automatically mean this popular restoration is out of the picture. But it will require us first performing a procedure known as augmentation or bone grafting to help rejuvenate some of the lost bone.

With grafting, we place processed bone grafting material in the jaw through a minor surgical procedure to form a scaffold for new bone to grow upon. After several months this can result in several millimeters of new growth maintaining the width of the underlying bone, which in turn may be able to support an implant.

Bone grafting is quite common, often performed at the same time as tooth extraction if there's going to be a time lag before installing an implant. Even if performed later, though, it can successfully rejuvenate lost bone and make it possible for you to take advantage of durable, life-like implants.

StainsfromWithinaToothRequireProfessionalWhitening

Whether performed in a dental office or using a home kit, teeth whitening applications are quite effective for bleaching exterior (extrinsic) stains on enamel surfaces. But what if your discoloration comes from inside the tooth? In this case, extrinsic teeth whitening won’t work — you’ll need to undergo an “internal bleaching” method, which can only be performed in a dentist's office.

There are a number of causes for “intrinsic” staining, including too much fluoride exposure or tetracycline use during childhood. One of the more common causes, though, occurs from root canal treatments used to remove the remnants of the pulp tissue inside a tooth’s pulp chamber and root canals. Certain cements used during the procedure to help seal in the filling material and leftover blood pigments can cause the tooth to darken over time.

To alleviate this discoloration, we use a bleaching agent, usually sodium perborate mixed with a diluted solution of hydrogen peroxide to achieve a safe, accelerated color change. After determining that the root canal filling is still intact and the bone is healthy, we create a small cavity in the back of the tooth to access the pulp chamber. The chamber is cleaned of any debris or stained material and then thoroughly irrigated. The original root canal filling is then sealed off to prevent leakage from the bleaching agent.

We then place the bleaching agent in the cleaned-out space with a cotton pellet and seal it in with a temporary adhesive. This step is repeated for several days until we achieve the desired shade of white. Once that occurs we then seal the dentin with a more permanent filling and then restore the cavity we created with a composite resin bonded to the enamel and dentin.

If we’re successful in achieving the desired color, intrinsic whitening could help you avoid more costly options like veneers or crowns for an otherwise healthy and attractive tooth. The end result would be the same — a beautiful smile without those unsightly stains.
