Dental Questions: Why are x-rays so useful?

In modern dentistry, we take x-rays fairly frequently. The average patient will receive four "periodic" radiographs annually, and an entire "full mouth" set of images every five to seven years (depending on multiple factors). Why do we need so many pictures? As it turns out, x-rays are an invaluable tool in diagnosing, documenting and monitoring changes in dental diseases. Take a look!

Dental x-rays give a dentist much more information that simply "looking in the mouth." In regards to tooth decay, radiographs can show cavities forming in areas that are impossible to visualize, such as in-between two teeth. Furthermore, they give more information on the location and depth of decay, helping inform decisions on placing fillings versus crowns, the risk of nerve irritation and what materials to use to fill the tooth. In most instances, we will not perform a filling on a tooth without an acceptable x-ray of the effected area. Radiographs are also necessary in assessing gum disease and bone loss. They can document the amount and pattern of recession, helping make decisions on dental cleanings and possible periodontal surgeries. In severe circumstances, heavy tartar hidden beneath the gum line will be visible on radiographs as well.

X-rays are also of great use in documenting and monitoring dental problems. Particularly in working with insurance companies, radiographs help demonstrate the necessity of certain procedures. This can improve the approval process and speed up reimbursements. Additionally, x-rays can help track the changes in dental conditions over time, aiding in decisions on treatment or continued monitoring. 

This image shows the progression of gum disease, as seen on an x-ray. The small white bumps that form on the sides of the teeth are tartar below the gumline. 

Radiographs are useful in visualizing much more than gum disease and tooth decay. Procedures like root canals, extractions and implants are impossible to perform without good radiographs. To learn more about the diagnostic tools we use in dentistry, please give our office a call.

Bacteria on your toothbrush?

In a recent article, the American Dental Association recognized that where and how you store your toothbrush has a significant impact on the types of bacteria it harbors. Toothbrushes left sitting out on bathroom counters to dry harbor many types of bacteria, some associated with the "other" things we do in the bathroom. Fortunately, there is no scientific evidence that these bacteria can harm your mouth.

To keep the general level of bacteria on your toothbrush at its lowest, the ADA recommends rinsing with tap water after brushing and allowing the brush to air dry. Putting the brush in a case or cover can retain moisture and actually cause more bacterial growth between the bristles. The brush (or brush head in electric units) should be changed every three to four months to maximize their cleaning ability. 

Finally, it is important to remember to never share a toothbrush. We now understand that both gum disease and tooth decay are bacterial in nature, and that these bacteria can be transferred from person to person. This is particularly important for children under the age of three who are highly susceptible to cavity-causing bacteria. If you have any other questions on dental hygiene or oral health products, please give our office a call! 

Get your teeth back in shape!

New year new you, right? If you're hitting the gym and shaping up as part of your new year's resolution, why not include your teeth in that plan? Here's a list of some of our favorite products and techniques for getting your oral health in peak performance.

Cut out the "slow" sugar- Are you a frequent snacker? Are you always sipping on a mocha or soda? These habits that involve consuming sugars and carbs over long periods of time are detrimental to your dental enamel health. Try to cut down on duration of consumption or switch to low/no sugar options like carrots, water or cheese (no crackers). Remember to rinse with water after every meal!

Get a mouth rinse that fits your needs- Most patients gravitate towards alcohol based mouth rinses like Listerine for the satisfying burn and promises of a healthier mouth. These types of rinses are great for patients with periodontal problems. However, many are at higher risk of developing cavities than periodontal disease and would not see much benefit from these products. For them, we would recommend a fluoride rinse like Act Fluoride or Carifree Ctx3 (available at our office). 

Go Electric- If you haven't tried an electric toothbrush yet, now is the time! They make brushing easier, more convenient and generally more enjoyable. Make sure to look for a product with a built in timer and pressure sensor. 

Brighten your smile- Not satisfied with the shade of your teeth? There are a number of awesome tooth whitening services and products available today. At our office, Dr. Kari Ann Hong offers both take-home bleach trays and in-office single visit whitening. If you are interested in trying an over-the-counter method, we recommend Crest Whitestrips and the like. 

Stick to the basics- Beyond any viral videos and secret techniques, brushing for two minutes with fluoride toothpaste twice a day and flossing daily is the hands down best way to keep on top of your oral hygiene. No other product, service or trick can match the efficacy of this regimen. Don't overcomplicate it!

Check in for your check ups- Regular dental exams and cleanings are crucial to your oral health. There is simply no substitute for the expertise of a dental hygienist and dentist in keeping your teeth in tip top shape. You'll save money too- catching small problems early on avoids the need for large fillings, crowns, extractions and other invasive procedures. 

We hope you found our list informative! If you have any questions or would like to schedule an appointment, please feel free to contact our office.

Using Dental Instruments at Home

With the rise of online marketplaces like Amazon and Ebay, many previously hard-to-find products are now readily available to purchase. Dentistry is no exception, with many options to buy professional cleaning instruments like scalers. Often listed as scrapers, tartar removers and hygiene tools, these items look identical to the ones used in the dental office. Are they safe to use at home? That's another story entirely. Read on for the complete answer!

In short, the only people that should be using hand scalers, polishing cups or other tooth cleaning instruments are licensed dental professionals. Many of these devices are technique sensitive and their misuse can lead to extensive damage to the gums and teeth. It is surprisingly easy to cut off gum tissue (that won't grow back), or chip away healthy enamel (leading to sensitivity). Furthermore, there is no way of knowing if the instruments you are using were made with quality materials. Porous metals can harbor bacteria or even break during use. Imagine the horror of having the tip of your scaler break off below your gumline!

Your best bet in keeping tartar off of your teeth is by brushing twice a day for two minutes and flossing daily. This regimen causes you to break up plaque deposits before they can harden into stubborn calculus. Regular dental cleanings will help ensure that you are keeping on top of your dental hygiene and allow us to clean your teeth in a hygenic and professional environment. Call us today to schedule your yearly exam and dental cleaning!

The Benefits of Sugar Free Gum

Are you a frequent gum-chewer? Men's Health Magazine recently published an article discussing how chewing sugar free gum can save you thousands of dollars in dental expenses. Find out why adding gum to your daily routine can help fight cavity causing bacteria!

Every time we eat or drink anything made with sugars or carbohydrates, our mouths turn acidic for a thirty minute period. This is caused by bacteria in our mouths processing sugars into their associated acids. Over time, the acid buildup weakens dental enamel and begins to form cavities in our teeth. These cavities tend to develop in areas that trap food, as bacteria have more fuel to turn into acid. This is one of the reasons why decay in common in between teeth and in the pits/grooves of posterior teeth. 

The Men's Health article correctly identifies that sugar free gum lacks the necessary ingredients to fuel bacterial acid production. In addition to this, gum helps loosen food that gets packed into our teeth after meals. Finally, chewing gum stimulates saliva flow which is a crucial factor in preventing tooth decay. Our saliva has incredible natural remineralizing properties and can have a tremendous effect on the progression of cavities.  

One topic the article does not address is the type of sweetener to look for in sugar free gum. Most brands use typical sugar substitutes like sorbitol and aspartame. However, chewing gum made with xylitol will add even more protective factors into your daily routine. Xylitol is a natural sugar alcohol that inhibits ability of bacteria to grow and stick to our teeth. While xylitol gum can be purchased at many stores, health food markets typically carry the best variety. You can also order it online from companies like Dr. John's Candies (our office's favorite!).

It is currently believed that Xylitol's maximum dental benefit comes from using it three to five times a day. However, it is not a substitute for flossing or brushing with a fluoride toothpaste. If you would like to know more about the protective factors of xylitol gum, how it is best used and what it does for our teeth, please give our office a call!

Floss and Flossing Alternatives

As you probably know, flossing is one of the best ways to preserve gum health, prevent decay and ward off tartar and plaque between the teeth. Even though this information nearly universal, only about 50% of Americans floss daily. Where does the discrepancy originate? For many, flossing either takes up too much time or doesn’t fit in with their schedules. Others simply don’t like using dental floss. With this in mind, we wanted to take a moment to introduce different types of floss, flossers and flossing alternatives. We are sure you can find a product that fits in with your dental care needs!

This Oral-B floss is both waxed and has a threader built in. 

Although there are many different brands of traditional dental floss on the market, they all generally produce the same results. The real difference comes from preferences in packaging, flavoring and texture. For patients who have found floss too “sharp” or “cutting” to use, we suggest looking for a waxed variety. Furthermore, those with orthodontic appliances, bridges or permanent retainers might benefit from floss with an attached threader tip. While these varieties may be more expensive than using a reusable threader, they offer added convenience and ease of use.

GUM Soft Picks are great alternatives to traditional floss.

Beyond traditional floss, there are a number of great alternatives designed to clean between your teeth. Many patients enjoy single-use flossers with handles, as they are portable, disposable and easy to use on-the-go. These devices are also great for kids who don’t yet have the motor skills to use regular floss. Others may prefer flossing picks, such as GUM Soft-Picks. These tree-shaped products expand below the gumline to remove plaque similarly to regular dental floss. Because of their shape, they great for cleaning around orthodontic appliances as well.

A Typical Water Flosser

Water flossers such as the Waterpik systems can also be utilized in cleaning between the teeth. Research suggests they are not as thorough or effective as other flossing methods, but they still represent an improvement over doing nothing. There are certain scenarios where water flossers can be a benefit to patients with periodontal disease, but this needs to be evaluated on an individual level. As with any oral hygiene product, make sure to follow the manufacturer’s recommendations when using water flossers. Regularly changing tips and cleaning water reservoirs prevents the buildup of harmful bacteria and biofilms.

At Thousand Oaks Family Dentistry, we know that our patients are presented with a number of choices in dental home care. We want to give you the information to make the best choices for your personal needs. If you would like to know more about flossing, toothbrushes, toothpaste or any other dental products, please give our office a call!

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!
