Tooth decay is a highly destructive dental disease, responsible along with periodontal (gum) disease for most adult tooth loss. And we become even more susceptible to it as we get older.
One form of decay that’s especially prominent among senior adults is a root cavity. Similar to a cavity in the crown (visible tooth), this form instead occurs at or below the gum line in the roots. They happen mainly because the roots have become exposed due to gum recession, a common consequence of periodontal (gum) disease and/or brushing too hard.
Exposed roots are extremely vulnerable to disease because they don’t have the benefit of protective enamel like the tooth crown, covered instead with a thin and less protective mineral-like material called cementum. Normally, that’s not a problem because the gums that would normally cover them offer the bulk of the protection. But with the gums receded, the roots must depend on the less-effective cementum for protection against disease.
Although we treat root cavities in a similar way to those in the crown by removing decayed structure and then filling them, there’s often an added difficulty in accessing them below the gum line. Because of its location we may need to surgically enter through the gums to reach the cavity. This can increase the effort and expense to treat them.
It’s best then to prevent them if at all possible. This means practicing daily brushing and flossing to remove bacterial plaque, the thin, built-up biofilm on teeth most responsible for both tooth decay and gum disease. You should also visit your dentist at least twice a year for professional cleanings and advanced prevention methods like topical fluoride to strengthen any at-risk teeth.
You should also seek immediate treatment at the first sign of gum disease to help prevent gum recession. Even if it has occurred, treating the overall disease could help renew gum attachment. We may also need to support tissue regeneration with grafting surgery.
Root cavities are a serious matter that could lead to tooth loss. But by practicing prevention and getting prompt treatment for any dental disease, you can stop them from destroying your smile.

In her decades-long career, renowned actress Kathy Bates has won Golden Globes, Emmys, and many other honors. Bates began acting in her twenties, but didn't achieve national recognition until she won the best actress Oscar for Misery — when she was 42 years old! “I was told early on that because of my physique and my look, I'd probably blossom more in my middle age,” she recently told Dear Doctor magazine. “[That] has certainly been true.” So if there's one lesson we can take from her success, it might be that persistence pays off.
When it comes to her smile, Kathy also recognizes the value of persistence. Now 67, the veteran actress had orthodontic treatment in her 50's to straighten her teeth. Yet she is still conscientious about wearing her retainer. “I wear a retainer every night,” she said. “I got lazy about it once, and then it was very difficult to put the retainer back in. So I was aware that the teeth really do move.”
Indeed they do. In fact, the ability to move teeth is what makes orthodontic treatment work. By applying consistent and gentle forces, the teeth can be shifted into better positions in the smile. That's called the active stage of orthodontic treatment. Once that stage is over, another begins: the retention stage. The purpose of retention is to keep that straightened smile looking as good as it did when the braces came off. And that's where the retainer comes in.
There are several different kinds of retainers, but all have the same purpose: To hold the teeth in their new positions and keep them from shifting back to where they were. We sometimes say teeth have a “memory” — not literally, but in the sense that if left alone, teeth tend to migrate back to their former locations. And if you've worn orthodontic appliances, like braces or aligners, that means right back where you started before treatment.
By holding the teeth in place, retainers help stabilize them in their new positions. They allow new bone and ligaments to re-form and mature around them, and give the gums time to remodel themselves. This process can take months to years to be complete. But you may not need to wear a retainer all the time: Often, removable retainers are worn 24 hours a day at first; later they are worn only at night. We will let you know what's best in your individual situation.
So take a tip from Kathy Bates, star of the hit TV series American Horror Story, and wear your retainer as instructed. That's the best way to keep your straight new smile from changing back to the way it was — and to keep a bad dream from coming true.

The American marketplace usually offers us plenty of buying choices — sometimes it seems too many. A case in point: the toothpaste aisle at your local supermarket.
It can be a bit overwhelming with all the razzle-dazzle packaging and exciting claims of “Whiter Teeth!” or “Fresher Breath!” But toothpaste really isn't that complicated, if you keep in mind its primary goal: to help you with your toothbrush remove disease-causing plaque from teeth surfaces.
And the vast majority can, thanks to ingredients you'll find in just about every brand. All toothpastes, for example, contain some form of abrasive material that boosts the mechanical action of brushing to remove plaque. This isn't new: the ancient Egyptians used ox-hoof ashes, burnt eggshells and pumice as abrasives. Today you'll find hydrated silica (originating from sand), hydrated alumina or calcium carbonate as abrasives on the ingredient list.
You also need some form of detergent to help loosen and break down substances that won't dissolve in water. Toothpaste detergent is much milder than that which you use on your dishes. The most common is sodium lauryl sulfate, a foaming agent found in shampoo and other beauty products. It's been used safely for half a century in toothpaste, although it can irritate the inner linings of some people's mouths. If this is a problem for you, you should look for toothpaste with a different detergent.
There is also a myriad of other ingredients, including binders, humectants (which help the toothpaste retain moisture) and flavorings. You may also find bleaching agents that help brighten your teeth, although they may not be strong enough to remove deep staining, something we would need to help you with.
And let's not forget one other frequent ingredient: fluoride. This natural chemical strengthens enamel and helps fight tooth decay as part of a disease prevention strategy. It's perhaps the most valuable ingredient you'll find in toothpaste, so make sure it's in your chosen brand.
If you want to simplify your decision, choose toothpaste with the seal of acceptance from the American Dental Association. The seal indicates the claims of the toothpaste manufacturer have been independently verified. You can trust those brands to help keep your teeth clean and free from disease. In the end, that's really what you want from your toothpaste.
