The basics for treating tooth decay have changed little since the father of modern dentistry Dr. G.V. Black developed them in the early 20th Century. Even though technical advances have streamlined treatment, our objectives are the same: remove any decayed material, prepare the cavity and then fill it.
This approach has endured because it works—dentists practicing it have preserved billions of teeth. But it has had one principle drawback: we often lose healthy tooth structure while removing decay. Although we preserve the tooth, its overall structure may be weaker.
But thanks to recent diagnostic and treatment advances we’re now preserving more of the tooth structure during treatment than ever before. On the diagnostic front enhanced x-ray technology and new magnification techniques are helping us find decay earlier when there’s less damaged material to remove and less risk to healthy structure.
Treating cavities has likewise improved with the increased use of air abrasion, an alternative to drilling. Emitting a concentrated stream of fine abrasive particles, air abrasion is mostly limited to treating small cavities. Even so, dentists using it say they’re removing less healthy tooth structure than with drilling.
While these current advances have already had a noticeable impact on decay treatment, there’s more to come. One in particular could dwarf every other advance with its impact: a tooth repairing itself through dentin regeneration.
This futuristic idea stems from a discovery by researchers at King’s College, London experimenting with Tideglusib, a medication for treating Alzheimer’s disease. The researchers placed tiny sponges soaked with the drug into holes drilled into mouse teeth. After a few weeks the holes had filled with dentin, produced by the teeth themselves.
Dentin regeneration isn’t new, but methods to date haven’t been able to produce enough dentin to repair a typical cavity. Tideglusib has proven more promising, and it’s already being used in clinical trials. If its development continues to progress, patients’ teeth may one day repair their own cavities without a filling.
Dr. Black’s enduring concepts continue to define tooth decay treatment. But developments now and on the horizon are transforming how we treat this disease in ways the father of modern dentistry couldn’t imagine.
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.
What your dentists in Ajax, Ontario want you to know
There are many tales about root canals which can make you fearful. The truth is root canals have become the state-of-the-art dental treatment to relieve tooth pain and still keep your tooth. Not too long ago, your only choice to relieve pain from a badly decayed tooth was to remove the tooth.
Now, thanks to modern techniques, materials and tools, you can save your painful tooth. The answer is root canal therapy. Your dentists at Ajax Dental Centre in Ajax, Ontario want to share with you why root canals are nothing to be afraid of.
Many dentists agree your best choice is to keep a tooth whenever possible. If you have a tooth removed, you are faced with:
- Living without the tooth, giving you an incomplete smile
- Replacing the tooth with a removable partial which can move around, making it difficult to eat or speak
- Replacing the tooth with bridgework, requiring restoration of the adjacent teeth to support the bridge
- Replacing the tooth with a dental implant which can be expensive
Why not keep your tooth with root canal therapy? Your dentists in Ajax, Ontario can perform root canal treatment using the latest anesthesia procedures to make you comfortable. When the treatment area is completely numb, your dentist will remove the diseased tissue from inside your tooth, replacing it with a sedative material. This material calms the tooth down, relieving pain and pressure. When your tooth is no longer painful, your dentist will place an inert, rubbery material called gutta-percha into the tooth. Your dentist will close the tooth with a filling, or place a dental crown to protect the tooth and your treatment is complete.
You may need a root canal if you have deep dental decay or tooth trauma from an accident or injury. Whatever the cause of your tooth pain, when you visit Ajax Dental Centre, you can be assured of the best experience before, during, and after your root canal treatment.
If you need a root canal, don’t be afraid. Let your dentists at Ajax Dental Centre in Ajax, Ontario take away your pain. Help is just a simple phone call away, so call today!
Parenthood comes with no manual — if it did it would surely include many essential tips to make your job easier while improving your children's lives. One important fact that surprises many people, is the age you should take your children to the dentist for their first dental appointment, age one. The reason that the age one dental visit is so important is that it establishes the foundation of oral healthcare for the rest of their lives. Unfortunately, some parents wrongly assume that because primary teeth “fall out anyway,” they do not need to worry about them. Nothing could be further from the truth!
One problem children may face is Early Childhood Caries (ECC) tooth decay. This is a type of tooth decay that occurs from sucking on a bottle filled with sugary liquids such as formula, juices and fruity drinks for extended periods of time and from a sleep-time bottle. ECC can affect all the primary (baby) teeth in infants soon after they come into the mouth.
Bringing your children into our office for their age one dental visit enables us to establish a friendly, trusting relationship with the whole family while we assess your children's oral health. During this consultation we will identify if the teeth and jaws are developing correctly, whether habits such as sucking on baby bottles are causing tooth decay or if there are other underlying issues that may indicate future problems. And this ounce of prevention often enables us to stop an anticipated problem before it even starts.
Tooth decay is a primary cause of tooth damage and loss, with annual treatment costs in the billions of dollars. It arises mainly from oral bacteria, which proliferates in the absence of effective oral hygiene. There are, however, other risk factors besides poor hygiene that could make you more susceptible to this disease.
Many people, for example, have genetically inherited deeper grooves (fissures) and depressions (pits) than the average tooth anatomy. These may be harder to reach with a toothbrush and can become havens for bacterial plaque. Others may have health conditions that indirectly affect the mouth: bulimia or anorexia, psychological conditions that involve self-induced vomiting, or GERD, gastro-esophageal reflux disease, in which stomach acid could regurgitate into the mouth. These conditions could result in a highly acidic mouth environment.
Some medical and — ironically — dental treatments could also increase your tooth decay risk. Some medications can reduce saliva flow, which inhibits acid neutralization and re-mineralization of enamel. Retainers, braces, bite guards or other dental appliances may also reduce the saliva wash over teeth, and can make brushing and flossing more difficult.
There are also risk factors that result from our lifestyle choices. Eating a lot of foods rich in sugars and other carbohydrates, for example, or acidic beverages like soda, energy or sports drinks contributes to the rise of bacteria in our mouths.
There are ways to reduce the effects of these risk factors. In addition to a daily habit of effective brushing and flossing, you should also include semi-annual cleanings and checkups at our office a part of your routine. If you have genetic, medical or dental issues that are out of your control, we can discuss solutions, such as alternatives to medications or different techniques for cleaning around dental appliances. For lifestyle-related factors, you should consider removing the habit or modifying it: for example, snacking at specific times or drinking acidic beverages only at mealtime.
While tooth decay is a serious, destructive disease, it is highly preventable. Addressing all your risk factors, not just hygiene, will reduce your chances of having it.
