Porcelain Veneers by Phoenix Dentist, Dr. Alan Ferguson

Veneers are very popular now because they create a dramatic change without the cost and complexity of caps (crowns). Porcelain veneers appear very natural because they are extremely thin and slightly translucent, just like tooth enamel.

The veneer is applied to the front of the teeth using dental cement. If you have discoloration, cracking, or minor crooked teeth, veneers are a great option for a quick and easy smile makeover.

Dental Science Experiment for Kids - Does Fluoride Strengthen Teeth?

Items Needed:

• Two hard-boiled eggs 
• Fluoride gel or solution, 4 oz to 6 oz
• Three clean plastic containers
• Several cans of dark soda
• Water

Experiment:

1) Place a hard-boiled egg in one of the plastic containers and cover it with the fluoride gel or solution. Let the egg soak in the fluoride for twenty-four hours. Remove the egg and rinse it with water. 

2) Place this “treated” egg in one of the two remaining clean containers, and place the “untreated” egg in the other. 

3) Cover both eggs with dark soda. Change the solution every 12 hours for two days. 

What was your Conclusion?

Results of the Experiment:

The “untreated” egg will begin to dissolve slightly, and the shell will become stained by the dark soda. 

The “treated” egg should not show a reaction until much later. The conclusion could be drawn that the use of fluoride helps strengthen teeth and protect them from decay. 

The Consequences of Missing Teeth

There are several negative consequences of missing some or all of your teeth. First, missing teeth will affect the aesthetics of your face. Not only will your smile be affected by the gaps from missing teeth, but if you’re missing too many teeth, the skin around your mouth won’t be supported properly and will start to sag, making your appear older than you are. Additionally, missing teeth will make it more difficult to chew your food properly and may even affect the way you speak. Finally, missing even one tooth may have emotional consequences; many people feel less confident about their smile when they are missing teeth. If you are currently missing any of your teeth, consider replacing them with dental implants, which can look and feel just like natural teeth.  

If you have missing teeth and are unsatisfied with the look of your smile, contact Dr. Alan Ferguson's office at (602) 242-5445 to schedule an oral evaluation.

Soft Tissue Diode Laser Treatment

One of the most effective tools our dental hygiene team has incorporated is the use of the soft tissue diode laser. During a 2-4 minute laser bacterial reduction, the bacterial count can be reduced from “millions” of bacteria to “hundreds”. This allows for quick profound healing of inflammation. It reduces the amount of bacteria that can enter the blood stream and travel to the brain, heart, liver, etc. The laser is also used during scaling and root planning treatment of periodontal disease.

The Truth about your Saliva

Did you know saliva contains components that can directly attack cariogenic (cavity/decay causing) bacteria, and it is also rich in calcium and phosphates that help to remineralize tooth enamel.  Demineralization of enamel occurs when pH levels fall as a result of acid production by bacteria. It can be reversed at early stages if the local environment can counteract acid production, restoring pH to neutral levels. Remineralization can occur through the replacement of lost mineral (calcium and phosphates) from the stores in saliva.

Vitamin D and Heart Disease

A growing number of studies support the idea that low levels of vitamin D are linked to an increased risk of heart disease, and that adding vitamin D supplements can help reduce this risk. Several large trials to learn more about this connection are underway, although there is not yet any conclusive evidence.

How Much Vitamin D do I Need?

It is well established that 400 International Units (IU) of vitamin D per day is necessary to prevent rickets, but an overwhelming number of physicians and researchers believe this level is too low to help achieve optimal health and reduce the risk of disease.

They say the Institute of Medicine (IOM) should consider revising their current vitamin D recommendations, which are below:

200 International Units IU per day for adults age 50 and younger

400 IU per day for adults aged 51 to 70 years

600 IU per day for adults aged 70 years.

It is not clear just how much vitamin D is needed for increased health and disease risk reduction. However, many physicians are now recommending 1,000 IU to 2,000 IU daily for most adults. Your doctor can determine how much vitamin D you need, and it is important to talk to him/her before increasing the amount of vitamin D in your diet. Too much vitamin D can cause the body to absorb too much calcium, which can cause kidney stones or damage.

Best Sources of Vitamin D

The best way to start adding vitamins to your diet is through foods. However, there are few foods that contain vitamin D, and your doctor may recommend supplements to ensure you have at least the minimum recommended amount of vitamin D each day. Even if you take supplements, you should still eat a variety of foods rich in vitamin D. Many foods rich in vitamin D contain additional disease-fighting nutrients.

Foods Rich in Vitamin D

Food or Supplement       Amount of Vitamin D (IU)

Chinook salmon, 4 oz. cooked 410

Shrimp, 4 oz. cooked      160

Multiple vitamins, most brands         400

Canned salmon, 3.5 oz.  360

Dannon Frusion® smoothie (10 oz.)           80

Tuna, light, canned in water, 3 oz.     200

Soy milk, fortified, 1 cup           100-120

Milk, 1 cup 100

Orange juice, fortified, 1 cup   142

Viactiv® Calcium soft chews, 1          500

Cod, 4 oz. cooked 63

Fortified breakfast cereals, most brands, ¾ – 1 cup       40

Margarine, fortified, 1 Tbsp    40

Large egg, 1           22

Supplements Containing Vitamin D

There are many available over-the-counter vitamin D dietary supplements. Two forms of vitamin D are used in these supplements — ergocalciferol (vitamin D2) and cholecalciferol (vitamin D3). Vitamin D2 is often considered a vegetarian source of vitamin D because it is derived from plants. Vitamin D3 can be obtained from synthetic or animal sources. Many practitioners prefer vitamin D3 because it is better absorbed and closer to the naturally occurring form of the vitamin in humans. However, both forms can be effective in increasing vitamin D levels in the blood.

Important Vitamins & Minerals for Oral Health

 

Vitamins and minerals are extremely important for your overall dental health. When there is a significant lack of Calcium for instance, the teeth will become weaker and start to erode. An inadequate dietary intake can affect your dental health, and the gums may become inflamed or the teeth become much weaker.

Vitamin A - this precious vitamin helps maintaining proper saliva flow so that bacteria are flushed away from the mouth. Also, Vitamin A maintains a healthy mucous membrane and mouth tissues. One of the best sources of Vitamin A include beef liver, sweet potatoes, melon, and spinach.

Vitamin B1 - helps maintaining the natural and healthy rose pink color of your gums, and it fights off tongue inflammation very successfully. Some of the best food sources containing Vitamin B1 include sunflower seeds, all sorts of vegetables and pork meat.

Vitamin B2 -is an extremely important vitamin for the prevention of cheilosis. This is condition when the corners of the mouth become fissured or start scaling. Mushrooms, milk products or lean steak are perfect sources of Vitamin B2.

It is important to mention that you can maintain proper dental health also if you start taking multivitamin capsules. Eat healthy and take these vitamins on a daily basis for at least a month to fuse your system with precious nutrients. Also, Vitamin B3 helps greatly fighting off gingivitis symptoms.

Vitamin B5 or Panthenoic Acid - patients who have undergone major dental health surgery, are advised to increase their Vitamin B5 intake as it helps with healing of the oral tissues in general. Some of the best food sources for this vitamin include liver, kidney, or egg yolks.

Folic Acid- or Vitamin B9 - is the best vitamin to help preventing inflammation of the tongue, and it also fights off the symptoms of chronic periodontitis. Also, patients with yeast infection problems are advised to increase their intake of Vitamin B9.

Top 5 Teeth Staining Culprits!

Culprit #1

Coffee and Tea. Many of us love a good old cup of Joe in the morning or a nice cup of tea. Unfortunately, drinking several cups per day will cause the tannin chemicals in coffee and tea to turn your teeth yellowish or a darker shade. If you must have that coffee or teas in the morning to get going, try to limit your intake to a cup per day. Avoid black coffee or tea - try milk-based choices if at all possible.


Culprit #2
Cigarettes. One of the worst offenders, cigarettes stain you teeth in multiple ways... not only do the effect of the tobacco leaves stain your teeth, the habit of smoking causes the smoker to continually expose the teeth to the staining process.


Culprit #3
Wine. Dark wines such as reds have the greatest staining impact on your teeth due to the dark purple colors found naturally in the grapes used for their production. Lighter wines have a lesser impact, but can still stain your teeth over time. Always try to rinse your mouth thoroughly with clear water after enjoying wine to minimize the staining impact of your vino.


Culprit #4
Soda / Pop / Cola. Whatever you call them, dark colored soft drinks can have a major staining effect on your teeth. The food coloring in soda heads right to the tooth and begins darkening almost immediately. If possible, limit your intake of soda, or enjoy lighter colored sodas. Using a straw to sip you soda can also help reduce the staining effect by reducing the contact between the soda and your teeth.


Culprit #5
Processed foods. Make processed foods are chocked full of chemicals and food colorants that make them look and taste mouth-wateringly yummy. Unfortunately, those artificial goodies are a big source of teeth staining badness. Don't believe us? Have a quick peek at your teeth after enjoying some chips or another snack. They'll most likely resemble the snack instead of their normal bright white selves.

Do Men’s and Women’s Hearts Burn Fuel Differently?

“Because the heart is the body’s number-one consumer of fat, when it starts using fat differently, there are consequences throughout the entire body,”

Researchers at the University of Illinois at Chicago College of Medicine will study gender differences in how the heart uses and stores fat—its main energy source—and how changes in fat metabolism play a role in heart disease, under a new $2 million, 4-year grant from the National Heart, Lung and Blood Institute.

When stressed, the heart changes how it uses fuel for energy. These changes may play a major role in the development of heart disease and are different in men and women, says E. Douglas Lewandowski, director of the UIC Center for Cardiovascular Research. The changes occur long before any symptoms, he said, and may be key to early diagnosis and treatment.

Lewandowski, who is principal investigator on the grant, uses imaging techniques he developed to see fat molecules and the rate at which they are being burned in beating hearts. In healthy hearts, the balance between using fat for energy and storing it in tiny droplets within the cells is in a dynamic equilibrium.

When a female heart is stressed, such as through chronic disease like hypertension, it becomes much less efficient at metabolizing fat, Lewandowski says. When a male heart is stressed, it starts using more sugar as fuel. These changes in the heart can also affect how fat is stored and used in other parts of the body.

Study Pinpoints Target for TMJD

People with temporomandibular joint disorder may be in luck.

Researchers located a protein that is essential in TMJD pain. This could lead to treatment for this painful disorder.

This information from the Duke Medicine researchers appears in the August issue of PAIN.

There isn’t much information known about what prompts TMJD. The research team pinpointed TRPV4, which is an ion channel protein that enables calcium to enter cells. Its involvement with inflammation and pain was examined.

The research team looked at normal mice and mice that were genetically engineered without TRPV4. Inflammation and pain was then created in the temporomandibular joints, similar to the way it impacts humans.

The mice without TRPV4 had a lower reduction in bite force, indicating they experienced less pain. When there was an increase in TRPV4, the correlation was a larger reduction in bite force.

The research also provided a compound to the normal mice that blocked TRPV4. The ensuing discovery was that inhibiting TRPV4 produced smaller reductions in bite force. The results were comparable to the results from mice without TRPV4.

One bit of information that surprised researchers was the idea that there was comparable bone erosion and inflammation in the jaw tissue for all mice. The amount of TRPV4 did not impact this. Essentially the damage is the same but the pain level varies.

Based on this study, it’s possible the TRPV4 could be utilized to develop new treatment for TMJ issues.

TMJD is the most common form of oral and facial pain and afflicts more than 10 million Americans. The chronic disorder results in severe pain that stems from chewing or biting down. There are no full-proof treatments.

Dental Care for Seniors

Advancing age puts many seniors at risk for a number of oral health problems, such as:

• Darkened teeth. . Caused, to some extent, by changes in dentin -- the bone-like tissue that underlies the tooth enamel -- and by a lifetime of consuming stain-causing foods and beverages.
• Dry mouth. Dry mouth is caused by reduced saliva flow, which can be a result of cancer treatments that use radiation to the head and neck area, as well as certain diseases, such as Sjogren's Syndrome, and medication side effects.
• Diminished sense of taste.  While advancing age impairs the sense of taste, diseases, medications, and dentures can also contribute to this sensory loss.
• Root decay.  This is caused by exposure of the tooth root to decay-causing acids. The tooth roots become exposed as gum tissue recedes from the tooth.
• Gum disease. Caused by plaque and made worse by food left in teeth, use of tobacco products, poor-fitting bridges and dentures, poor diets, and certain diseases, such as anemia, cancer, and diabetes, this is often a problem for older adults.
• Tooth loss. Gum disease is a leading cause of tooth loss.
• Uneven jawbone.  This is caused by tooth loss.
• Denture-induced stomatitis.   Ill-fitting dentures, poor dental hygiene, or a buildup of the fungus Candida albicans cause this condition, which is inflammation of the tissue underlying a denture.
• Thrush.  Diseases or drugs that affect the immune system can trigger the overgrowth of the fungus Candida albicans in the mouth.

Age in and of itself is not a dominant or sole factor in determining oral health. However, certain medical conditions, such as arthritis in the hands and fingers, may make brushing or flossing teeth difficult to impossible to perform. Drugs can also affect oral health and may make a change in your dental treatment necessary.

Gum Disease and Heart Disease

Heart Disease

Several studies have shown that periodontal disease is associated with heart disease. While a cause-and-effect relationship has not yet been proven, research has indicated that periodontal disease increases the risk of heart disease.
Scientists believe that inflammation caused by periodontal disease may be responsible for the association.
Periodontal disease can also exacerbate existing heart conditions. Patients at risk for infective endocarditis may require antibiotics prior to dental procedures. Your periodontist and cardiologist will be able to determine if your heart condition requires use of antibiotics prior to dental procedures.

Stroke

Additional studies have pointed to a relationship between periodontal disease and stroke. In one study that looked at the causal relationship of oral infection as a risk factor for stroke, people diagnosed with acute cerebrovascular ischemia were found more likely to have an oral infection when compared to those in the control group.  perio.org

Diabetes and Periodontal Disease

Diabetic patients are more likely to develop periodontal disease, which in turn can increase blood sugar and diabetic complications.

People with diabetes are more likely to have periodontal disease than people without diabetes, probably because people with diabetes are more susceptible to contracting infections. In fact, periodontal disease is often considered a complication of diabetes. Those people who don't have their diabetes under control are especially at risk.
Research has suggested that the relationship between diabetes and periodontal disease goes both ways - periodontal disease may make it more difficult for people who have diabetes to control their blood sugar.
Severe periodontal disease can increase blood sugar, contributing to increased periods of time when the body functions with a high blood sugar. This puts people with diabetes at increased risk for diabetic complications. perio.org

Overall Oral Health There's a growing trend within general dentistry that stresses the importance of overall oral health – not only health of teeth and gums, but of all the soft tissues in the oral cavity and oropharynx. Growing numbers of clinical practitioners now incorporate routine intra- and extra-oral head and neck exams into their hygiene appointments to screen for dysplasia, oral cancer and a host of other oral diseases. Oral CancerApproximately 36,540 Americans will be diagnosed with cancer of the oral cavity and pharynx in 2010. During the same time period 7,880 Americans will die of oral cancer.* One of the VELscope system's most important tasks is to help identify areas that might, if not identified and treated, progress to oral cancer. The statistics below, from the National Cancer Institute's SEER Database, 1999-2006, are a compelling argument for regular VELscope exams: Found early, while still Localized (confined to the primary site), oral cancer's five-year survival rate is good: about 83%. Only 33% of all oral cancer discoveries fall into this category. Found while Regional (progressed to regional lymph nodes) the five-year survival rate drops significantly, to about 55%. Approximately 46% of all oral cancer discoveries are Regional. Found late, oral cancer's five-year survival rate is poor: approximately 32%. This accounts for approximately 14% of all oral cancer findings. Clearly, finding oral cancer in its early stages is key to survival. Routine VELscope examinations can improve the morbidity and mortality of oral-cancer, because the VELscope system assists in early detection, potentially saving lives through less invasive, more effective treatment. HPV — Changing the Demographics of Oral Cancer An increasing body of evidence points to a strong link between particular strains of the human papilloma virus (HPV, most notably strain 16) and a certain type of oral cancer that occurs in the oropharynx. HPV 16 is the same strain associated with almost all cervical cancer. Many experts now recommend that all adult patients over the age of 18 receive a thorough intra- and extra-oral head and neck exam annually. For more information on oral cancer, please visit the Oral Cancer Foundation. * All statistics from the National Cancer Institute's SEER Database.
