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.

A certain news story a few years ago notwithstanding, dentists still recommend flossing along with brushing to adequately remove disease-causing plaque. If there is any controversy at all about flossing, it's whether you should perform it before brushing or after. Each perspective has good reasons.
"Brush First" proponents say their way encourages the formation of a daily hygiene habit, a must for preventing disease. That's because brushing can remove most of the plaque built up on the teeth, while flossing can then remove what's left. If you floss first, though, you'll have to plow through the sticky film with the floss, which can be an unpleasant experience. Facing that every day could make a person less enthusiastic about developing a hygiene habit.
But it's not just about the sensation: depending on the person, the plaque buildup could be so much that the floss becomes clogged with it. You're then moving the plaque rather than removing it. Brushing a lot of the plaque out of the way first will increase the cleaning power of your floss.
The "Floss First" team, though, is undaunted with their own take on the matter. Flossing can loosen up any stuck debris between teeth, making it easier for brushing to clear it away. It can also expose plaque-covered areas between teeth to allow better contact with the fluoride in your toothpaste. And, the amount of plaque you're pulling out in certain areas during flossing could tip you off to beef up your brushing efforts on those areas of heavier plaque accumulation.
One of the prime reasons for flossing first, though, goes back to the comfort factor and human nature. To be honest, for most people flossing isn't as much "fun" as brushing. If you put it off until after brushing, you're more likely not to do it if you find it unpleasant. Doing it first gets the less likeable task out of the way, so you can then do the more likeable one, brushing.
Which approach is best for you? It's really a personal decision, one you can discuss with your dentist. Try both ways, and see which one seems better. But whether you floss first or last, do floss to really reduce your risk for dental disease.

Tooth decay is a destructive oral disease, which along with periodontal (gum) disease is most responsible for tooth loss. And as you age, your disease risk goes up.
One form of decay older people often experience is root cavities. Unlike those occurring in the visible crown, root cavities often occur below the gum line and are especially destructive to tooth structure.
That's because, unlike the crown protected by ultra-hard enamel, the roots are covered by a thin, mineralized material called cementum. Although cementum offers some protection, it can't compare with the decay-resistant capacity of enamel.
The roots also depend on gum coverage for protection. But unfortunately, the gums can shrink back or recede, usually due to gum disease or over-aggressive brushing, and expose some of the root surface. With only the cementum to protect them, the roots can become highly susceptible to decay. If a cavity forms here, it can rapidly advance into the tooth's interior, the pulp, weakening the tooth and increasing its risk of loss.
To stop the decay, we must treat root cavities much like we do with crown cavities: by removing any decayed structure and then filling the cavity. But root cavities are often more difficult to access depending on how far below the gum line they extend. We may need to perform minor gum surgery to expose the cavity to treat it.
But as with any form of tooth decay, the best strategy is to prevent root cavities in the first place. Your first line of defense is a daily hygiene habit of brushing and flossing to remove dental plaque, the main cause for tooth decay. You should also visit your dentist at least twice a year (or more, if recommended) for more thorough cleanings and checkups. Your dentist can also recommend or prescribe preventive rinses, or apply fluoride to at-risk tooth surfaces to strengthen them.
You should also be on the lookout for any signs of gum disease. If you see swollen, reddened or bleeding gums, see your dentist as soon as possible. Stopping possible gum recession will further reduce your risk of root cavities.

While pregnancy is an exciting time for expectant mothers, it can pose extra health challenges. This is especially true regarding dental health.
Because of hormonal changes that naturally occur during pregnancy, your teeth and gums are at higher risk for dental disease. These changes can increase cravings for carbohydrates, particularly sugar. Increased sugar consumption feeds bacteria found in dental plaque, which is most responsible for tooth decay and periodontal (gum) disease.
Hormonal changes can also make your gums more susceptible to infection. Conditions may be favorable for a form of gum disease called pregnancy gingivitis, which can begin as an infection in the surface layers of the gums. But like other forms of gum disease, pregnancy gingivitis can advance below the gum line and lead to serious health consequences.
Because of this "pregnancy effect" on your teeth and gums, there are some things to which you should pay heed while you're expecting. First and foremost, keep up a daily regimen of brushing and flossing to remove accumulated dental plaque. You should also control your sugar intake to minimize bacterial growth that can cause disease.
It's also important for you to continue regular dental visits during your pregnancy. Your dentist will monitor your dental health and initiate treatment if you begin to show signs of disease. Besides professional cleanings, your dentist may also prescribe antibacterial mouthrinses to combat bacteria.
As far as dental procedures, essential treatments like fillings, root canals or extractions are usually considered safe to perform during pregnancy. But elective treatments of a cosmetic nature are best postponed until after your baby's delivery.
One last tip: because of the higher risk of tooth decay or gum disease, be on the lookout for any abnormal signs in your mouth. This includes spots on the teeth, tooth pain or swollen, reddened or bleeding gums. If you see any of these signs, see your dentist as soon as possible.
Your teeth and gums are indeed at risk for disease during pregnancy. But daily hygiene, regular dental care and attention to signs of disease can help keep that danger at bay.

There is a primary principle dentists follow regarding tooth decay—treat it as soon as you find it. Something as simple and routine as filling a cavity could prevent future tooth loss.
But treating a cavity at or below the gum line could be anything but simple and routine. Older adults who may also be dealing with gum recession are more likely to have these kinds of cavities where the gums block clear access to it.
But there is a way to access gum-covered cavities with a minor surgical procedure known as crown lengthening. Crown lengthening is commonly used in cosmetic dentistry to expose more of the visible teeth when there's an overabundance of gum tissue or if the teeth are disproportionately small. We can use it in this instance to surgically relocate the blocking gum tissue out of the way of the cavity.
After numbing the area with local anesthesia, tiny incisions will be made in the gums to create a tissue flap. After reshaping the underlying bone to recreate normal anatomy but at a different level, this flap is then moved and sutured to a new position. This exposes enough tooth structure so that the cavity can be repaired after gum healing.
As with any minor surgery, there's a very slight risk of bleeding and/or infection with crown lengthening. If you undergo this procedure, you'll receive post-care instructions for the first few days afterward including avoiding strenuous activities, eating only soft foods and using an ice pack the day of surgery to help control swelling.
This versatile procedure can help save a tooth that might otherwise be lost due to decay. And, it might even improve your appearance.
