Hidden Sugars

While we typically think of tooth decay as a childhood disease, it can affect anyone at any age. In fact, while cavities are slowly declining in young children, 92% of adults over the age of 20 have some form of decay. This is largely attributed to "hidden sugars" in our daily diets. 

Nearly everyone tries to eat healthy and stay away from sweets and sugary drinks. However, it is important to understand that sugars can "hide" in the foods we eat every day. These hidden sugars are particularly detrimental when used as snacks or consumed over a long period of time. Duration, not quantity, is the most important factor in the decay process. A prime example of hidden sugars would be cheese crackers like Goldfish or Cheez-its. While they may have a low sugar content by recipe, our saliva can break down the carbohydrates into smaller glucose and fructose molecules. Combine this with the the crackers' sticky nature and you have a perfect storm for tooth decay!

Other sugars we consume aren't quite as discreet, but still manage to sneak in without us noticing. This is particularly true in an office environment where coworkers are constantly bringing in donuts, birthday cakes and sweet treats. While we may not plan or think of these foods as part of our diet, they still can have a serious effect on our teeth. 

Asking someone to give up their favorite snacks "cold turkey" is usually impossible. Instead, we suggest keeping the duration and number of snacking sessions to a minimum. For example, instead of eating a box of raisins over the course of an afternoon, try to consume all of them in an even fifteen minute period. Also, make sure to follow any snack or meal with a rinse of water and some xylitol gum. This combination is a quick and easy way to minimize bacterial activity after an influx of sugar.

If you would like to know more about tooth decay, what causes it and how we can stop the process, please call our office. The most important component of dental care is prevention, and we want to keep our patients equipped with the latest research in hygiene and oral health. 

Dental Questions: Can a dentist diagnose decay in the mouth that is not evident on an x-ray?

Yes, it is absolutely possible to diagnose decay in the mouth from a visual exam with a mirror and explorer.  Decay on the biting surfaces of the teeth can often be hiding in a pit, groove or fissure of the outer enamel layer. On a visual exam, the area can look like a dark spot in the white of the enamel or an explorer can get stuck in the cavitation. The x-ray won’t show the decay in this area if is still primarily in the enamel layer. However, once decay spreads past this first layer of defense and lands in the internal dentin layer of the tooth, it will definitely show up on an xray.

Take a look at the following pictures, taken from the same patient in the same appointment:

In reviewing the radiographs, there is no apparent decay in this patient’s molars. There aren’t any suspicious shadows or defects in the enamel and the teeth generally look healthy. 

However, a visual examination reveals the beginnings of a cavity forming in the two maxillary molars. The geography of the tooth allows the decay to be hidden as the three dimensional object is translated into a 2D X-ray. Conversely, not all pit and fissure stains are cavities. Dentists can recognise unique shapes, patterns and texture changes in teeth that differentiate staining from active decay. This further highlights the importance of the entire dental exam to make a proper diagnosis. 

Dentistry Through The Ages: Elderly Patients

Greetings and welcome to our on-going blog series, Dentistry Through the Ages. In these blog posts, we will cover age-group specific dental needs and concerns. Your life is constantly changing, and we want to equip you with the best information possible to keep your teeth healthy!

In this article, we will be covering the dental needs of our elderly patients. Current projections estimate that persons aged 65 and older represent between 13% and 17% of the current United States population. As such, the dental healthcare industry is becoming better adapted and prepared to handle the needs of an aging population. Our office wants to take a moment to highlight some predominant oral health concerns to keep you aware and healthy!

Dry Mouth (formally known as xerostomia) is one of the biggest concerns when treating elderly patients. As we progress into old age, our bodies become more susceptible to diseases, injuries and other medical concerns. These conditions will often result in new prescriptions and medications- many of which decrease saliva flow or limit the function of salivary glands. This, combined with the natural degradation of the parotid gland (a major salivary gland) with age, leaves many patients with little to no resting saliva.

Our saliva are crucial to limiting the activity and progress of cavity forming bacteria. As such, many patients will see an increase in cavities as they transition to old age. Certain biological factors put the elderly population at particular risk for root surface cavities, where decay arises in areas of gum recession or where the tooth meets the gum tissue. However, there are a number of great products to counteract the progression of cavities in old age. Fluoride products, remineralizing gels and xylitol rinses can all help keep decay and bacteria at bay. As an added bonus, xylitol products can help stimulate saliva flow to help combat dry mouth directly!

In addition to xerostomia, many elderly patients will encounter increased incidences of periodontal disease. Limited salivary flow, years of bacterial attacks and reduced immune response can all culminate to a loss of gum tissue and bone level. Many patients will be candidates for deep cleanings or a more frequent cleaning schedule to keep plaque and tartar levels down. Others with advanced periodontal disease may even be candidates for the services of a periodontist (gum tissue specialist).

For patients with very aggressive periodontal disease, teeth may need to be extracted. Depending on the extent of the condition, number of extractions needed and patient’s overall health, our office offers a number of tooth replacement options. Single teeth can be replaced permanently with bridges and implants or removably with a partial denture (depending on the location of the gap). Partial dentures use a metal framework to replace teeth and gum tissue back to a natural appearance. They benefit from using clasps to mount to permanent teeth and sit on the gum tissue.

Full dentures can provide the same esthetic results as partial dentures for edentulous (toothless) patients. Full dentures typically require about four to five appointments to take proper impressions, fabricate the denture, adjust it and deliver the final product. While this process is lengthy, it helps ensure a great fit that minimizes irritation to the gum tissue.

We hope you found our review of oral health concerns in the elderly informative and helpful. Our office is fully committed and equipped to care for aging patients and wants you to know you are in great hands.  If you have any questions about your oral health needs, our treatment options or any other concerns, please give us a call. We are always available to answer your questions!

CAMBRA and Preventative Dentistry

    At Thousand Oaks Family Dentistry, we tend to ask a lot of questions. Some of them are are expected (“Do you floss regularly?”), while others (“What type of water do you drink?/Do you chew gum?”) might raise some confusion. While our investigations might seem slightly tedious, they are critical to our practice philosophy and how we treat our patients. These questions are part of a revolutionary preventative dentistry strategy known as CAMBRA.

    CAMBRA, or Caries (cavity) Management By Risk Assessment is a series of weighted factors and criteria that allow dentists to quickly and effectively determine tooth decay risk. By going over your dietary habits, home care techniques and medical history, we can obtain an accurate picture of how your tooth decay will progress (or continue to stay static) in the coming years. While this isn’t a “crystal ball” looking into your smile’s future, it is the best marker we have at determining your unique oral health situation.

    This screening technique relies on a simple thought process: if your habits and lifestyle lend themselves to an acidic, dry or bacteria prone mouth environment, then you will be at a greater risk for tooth decay. While this may seem obvious, what CAMBRA does is determine which factors are the most destructive, which ones can be “treated” and which ones are based on habits or lifestyle. Using this information, we can help our patients better manage their tooth decay, ultimately resulting in fewer office visits, fillings and incidences of dental discomfort.

Once we have determined your risk for tooth decay, we can make recommend products that can help you better manage your unique risks. One of these great products is Carifree Ctx3. This mouthwash-like rinse combines pH neutralization (to minimize mouth acidity), fluoride (to rebuild enamel) and xylitol (to naturally inhibit acid-producing bacteria). We love this rinse because it targets three of the decay cornerstones outlined in CAMBRA in an easy and convenient delivery method.

    Here is an example of how CAMBRA works: A 24 year old male comes in with and is diagnosed with a cavity on one of his molars. We go over his medical history and see he is taking medications that cause dry mouth. When discussing his eating habits, we find that he is a frequent snacker and enjoys sticky, processed foods. Finally, we note that he almost exclusively drinks bottled water and sports drinks. Using CAMBRA, we can determine that his tooth decay risk is likely caused by his medication and eating/drinking habits. We then recommend that he considers cutting back on snacking and sticking to 3 meals a day, stops drinking sports drinks (when not necessary) and starts drinking more filtered water, to both counteract the dryness caused by his medication and add fluoride exposure. While we will still need to treat his current tooth decay, we have now given him the knowledge and tools to better manage his oral care in the future.

    At our office, we treat every patient as a unique individual with unique needs. This is why CAMBRA fits so well with how we perform dentistry. It is not a one-size-fits-all approach, but rather a dynamic diagnosing tool that flexes with you. We are proud to operate our office on the CAMBRA model, and are incredibly satisfied with the results our patients have seen!
