As we age we become more susceptible to dental diseases. A common but often initially unnoticed problem for seniors is root decay.
We’re all familiar with tooth decay in the crown, the visible tooth above the gum line. Bacteria feeding on leftover sugar in the mouth produce acid, which at high levels erodes the teeth’s protective enamel. This forms cavities and, if untreated, deeper infection within the tooth that could reach the bone via the root canals.
But decay can also directly attack a tooth’s roots below the gum line. Roots are made of dentin and covered by a very thin layer of mineralized tooth structure called cementum. Cementum, which is much softer than enamel, is often lost because of its thinness, thus exposing the root’s dentin. This can make the area more susceptible to decay than the enamel-covered crown. Normally, though, the roots also have the gums covering them as added protection against bacterial infection.
But gum recession (shrinkage), a common experience for people in their later years, can expose the root surfaces. As a result, the roots become much more susceptible to decay. And an ensuing infection could spread more quickly into the interior of the tooth than decay originating in the crown.
That’s why it’s important to remove the decayed material and fill the root cavity to prevent the infection’s spread. While similar to a crown filling, the treatment can be more difficult if the root cavity extends below the gum line. In this case, we may need to perform a surgical procedure to access the cavity.
There are other things we can do to help prevent root cavities or limit their damage. We can apply fluoride varnish to strengthen the teeth and provide extra protection against cavities, or prescribe a fluoride rinse for use at home. We can also keep an eye out and treat periodontal (gum) disease, the main cause for gum recession.
The most important thing, though, is what you do: brush and floss thoroughly each day to remove bacterial plaque and limit sugary or acidic foods in your diet. Preventing decay and treating cavities as soon as possible will help ensure you’ll keep your teeth healthy and functional all through your senior years.
Once upon a time, celebrities tried hard to maintain the appearance of red-carpet glamour at all times. That meant keeping the more mundane aspects of their lives out of the spotlight: things like shopping, walking the dog and having oral surgery, for example.
That was then. Today, you can find plenty of celebs posting pictures from the dentist on social media. Take Julianne Hough, for example: In 2011 and 2013, she tweeted from the dental office. Then, not long ago, she shared a video taken after her wisdom teeth were removed in December 2016. In it, the 28-year-old actress and dancer cracked jokes and sang a loopy rendition of a Christmas carol, her mouth filled with gauze. Clearly, she was feeling relaxed and comfortable!
Lots of us enjoy seeing the human side of celebrities. But as dentists, we’re also glad when posts such as these help demystify a procedure that could be scary for some people.
Like having a root canal, the thought of extracting wisdom teeth (also called third molars) makes some folks shudder. Yet this routine procedure is performed more often than any other type of oral surgery. Why? Because wisdom teeth, which usually begin to erupt (emerge from beneath the gums) around age 17-25, have the potential to cause serious problems in the mouth. When these molars lack enough space to fully erupt in their normal positions, they are said to be “impacted.”
One potential problem with impacted wisdom teeth is crowding. Many people don’t have enough space in the jaw to accommodate another set of molars; when their wisdom teeth come in, other teeth can be damaged. Impacted wisdom teeth may also have an increased potential to cause periodontal disease, bacterial infection, and other issues.
Not all wisdom teeth need to be removed; after a complete examination, including x-rays and/or other diagnostic imaging, a recommendation will be made based on each individual’s situation. It may involve continued monitoring of the situation, orthodontics or extraction.
Wisdom tooth extraction is usually done right in the office, often with a type of anesthesia called “conscious sedation.”Â Here, the patient is able to breathe normally and respond to stimuli (such as verbal directions), but remains free from pain. For people who are especially apprehensive about dental procedures, anti-anxiety mediation may also be given. After the procedure, prescription or over-the-counter pain medication may be used for a few days. If you feel like singing a few bars, as Julianne did, it’s up to you.

Other than the common cold, tooth decay is the most prevalent disease in the world. And while a cavity or two may seem like a minor matter, tooth decay’s full destructive potential is anything but trivial. Without proper prevention and treatment, tooth decay can cause pain, tooth loss and, in rare cases, even death.
This common disease begins with bacteria in the mouth. Though these microscopic organisms’ presence is completely normal and at times beneficial, certain strains cause problems: they consume left over carbohydrates in the mouth like sugar and produce acid as a byproduct. The higher the levels of bacteria the higher the amount of acid, which disrupts the mouth’s normal neutral pH.
This is a problem because acid is the primary enemy of enamel, the teeth’s hard protective outer shell. Acid causes enamel to lose its mineral content (de-mineralization), eventually producing cavities. Saliva neutralizes acid that arises normally after we eat, but if the levels are too high for too long this process can be overwhelmed. The longer the enamel is exposed to acid, the more it softens and dissolves.
While tooth decay is a global epidemic, dental advances of the last century have made it highly preventable. The foundation for prevention is fluoride in toothpaste and effective oral hygiene — daily brushing and flossing to removing plaque, a thin film of food remnant on teeth that’s a feeding ground for bacteria, along with regular dental visits for more thorough cleaning and examination. This regular regimen should begin in infancy when teeth first appear in the mouth. For children especially, further prevention measures in the form of sealants or topical fluoride applications performed in the dentist office can provide added protection for those at higher risk.
You can also help your preventive measures by limiting sugar or other carbohydrates in your family’s diet, and eating more fresh vegetables, fruit and dairy products, especially as snacks. Doing so reduces food sources for bacteria, which will lower their multiplication and subsequently the amount of acid produced.
In this day and age, tooth decay isn’t a given. Keeping it at bay, though, requires a personal commitment to effective hygiene, lifestyle choices and regular dental care. Doing these things will help ensure you and your family’s teeth remain free from this all too common disease.
