As your dental provider, we're always alert for signs of tooth decay or periodontal (gum) disease, the two leading causes of tooth loss. But we're also watching for less common conditions that could be just as devastating.
Root resorption falls into this latter category: it occurs when a tooth's root structure begins to break down and dissolve (or resorb). It's a normal process in primary ("baby") teeth to allow them to loosen and give way when permanent teeth are ready to erupt.
It's not normal, though, for permanent teeth. Something internally or—more commonly—externally causes the root structure to break down. External resorption usually occurs at the neck-like or cervical area of a tooth around the gum line. Known as external cervical resorption (ECR), it can first appear as small, pinkish spots on the enamel. These spots contain abnormal cells that cause the actual damage to the root.
We don't fully understand how root resorption occurs, but we have identified certain factors that favor its development. For example, it may develop if a person has experienced too much force against the teeth during orthodontic treatment. Injury to the periodontal ligaments, teeth-grinding habits or some dental procedures like internal bleaching may also contribute to later root resorption.
Early diagnosis is a major part of effective treatment for root resorption. Because it's usually painless and easily overlooked, resorption is often too difficult to detect in its early stages without x-rays—a good reason for regular dental exams. Beginning spots or lesions are usually small enough to surgically remove the tissue cells causing the damage and then filled with a tooth-colored filling material. If it has advanced further, we may also need to perform a root canal treatment.
At some point, the damage from root resorption can be too great, in which case it might be best to remove the tooth and replace it with a dental implant or similar restoration. That's why catching root resorption early through regular dental exams can give you the edge for saving your tooth.

When die-hard music fans hear that their favorite performer is canceling a gig, it’s a big disappointment—especially if the excuse seems less than earth-shaking. Recently, British pop sensation Dua Lipa needed to drop two dates from her world tour with Bruno Mars. However, she had a very good reason.
“I’ve been performing with an awful pain due to my wisdom teeth,” the singer tweeted, “and as advised by my dentist and oral surgeon I have had to have them imminently removed.”
The dental problem Lipa had to deal with, impacted wisdom teeth, is not uncommon in young adults. Also called third molars, wisdom teeth are the last teeth to erupt (emerge from beneath the gums), generally making their appearance between the ages of 18-24. But their debut can cause trouble: Many times, these teeth develop in a way that makes it impossible for them to erupt without negatively affecting the healthy teeth nearby. In this situation, the teeth are called “impacted.”
A number of issues can cause impacted wisdom teeth, including a tooth in an abnormal position, a lack of sufficient space in the jaw, or an obstruction that prevents proper emergence. The most common treatment for impaction is to extract (remove) one or more of the wisdom teeth. This is a routine in-office procedure that may be performed by general dentists or dental specialists.
It’s thought that perhaps 7 out of 10 people ages 20-30 have at least one impacted wisdom tooth. Some cause pain and need to be removed right away; however, this is not always the case. If a wisdom tooth is found to be impacted and is likely to result in future problems, it may be best to have it extracted before symptoms appear. Unfortunately, even with x-rays and other diagnostic tests, it isn’t always possible to predict exactly when—or if—the tooth will actually begin causing trouble. In some situations, the best option may be to carefully monitor the tooth at regular intervals and wait for a clearer sign of whether extraction is necessary.
So if you’re around the age when wisdom teeth are beginning to appear, make sure not to skip your routine dental appointments. That way, you might avoid emergency surgery when you’ve got other plans—like maybe your own world tour!

Dental veneers are a great way to transform a smile without the expense or effort often required of other restorations. These thin layers of dental material adhere to the front of teeth as a "mask" to cover chips, heavy staining or other blemishes.
Still, veneers require attention to detail for a successful outcome. Here's a step-by-step look at changing your dental appearance with veneers.
Step 1: Considering your options. While most veneers are made of dental porcelain, composite resin materials are increasingly popular. Although more prone to chipping or staining, composite veneers don't require a dental lab for fabrication. Another option, depending on your dental situation, are ultra-thin veneers that require little to no tooth preparation. Your dentist will help you decide which options are best for you.
Step 2: "Test driving" your new smile. We can help you "see" your future smile with special software that creates a computer image of your teeth with the planned veneers. We can also use composite material to fabricate a "trial smile" to temporarily place on your teeth that can give you the feel as well as the look of your future smile.
Step 3: Preparing your teeth. Unless you're getting no-prep veneers, we'll need to modify your teeth before attaching veneers. Although only 0.3 to 0.7 millimeters thick, veneers can still appear bulky on unprepared teeth. They'll look more natural if we first remove a small amount of enamel. A word of caution, though: although slight, this enamel removal permanently alters your teeth that will require them to have some form of restoration from then on.
Step 4: Attaching your new veneers. After the planning phase (which includes color matching to blend the veneers with the rest of your teeth), a dental lab creates your veneers if you've opted for porcelain. After they're delivered, we'll clean and etch the teeth with a mild acidic gel to increase the bonding effect. We'll then permanently attach the veneers to your teeth with a very thin but ultra-strong resin luting cement that creates a unified bond between the veneers and teeth.
Following these steps is the surest way to achieve a successful outcome. With due care you're sure to enjoy the effects for a long time to come.
