Dr. Urban on Today’s Dentistry/Making Teeth Stronger

Last time I discussed using xylitol sweeteners to lower the incidence of tooth decay. This is good prevention. But what happens when decay first begins and teeth become sensitive? There is now a dental cream that can be applied at home that will help harden teeth by remineralizing the soft enamel of the tooth.

The active ingredient of this cream is RECALDENT™ (CPP-ACP). It is marketed by GC America Inc. in the product named MI Paste Plus. It is also available in the Trident XtraCare with Recaldent and Trident Recaldent Calcium Sugar-free tablets.

MI Paste is pleasant tasting and adheres to the tooth surface acting like a magnet for minerals to bond back onto the tooth surface. This makes the tooth tougher and more resistant to acid etching from bacteria, foods, and saliva.

Who would benefit from MI Paste? It is safe for 1 year old children to senior citizens. MI Paste is dispensed by dentists to people who have a moderate to high decay rate. It is good for people who have a high acid level in their saliva. MI Paste helps reduce the erosion caused by dry mouth. If bleaching your teeth causes them to be sensitive you should apply the cream immediately after bleaching. If you are undergoing chemotherapy or radiation therapy to the head and neck area, MI Paste will help protect the teeth during this trying time.

MI Paste without fluoride is a better dentifrice for little kids who can barely brush their teeth. When they become older they can use regular toothpaste and then apply a small amount to their teeth before school and before bedtime.

This cream is also recommended for kids wearing braces. It is very difficult to fully clean every nook and cranny while the brackets and wires are on the teeth. MI Paste helps neutralize the acid levels caused by the remaining bacteria. Despite all efforts to protect the teeth white spots may appear after removing the brackets. The cream can then be applied to help remineralize these white spots (some white spots can be the beginning of decay).

Dry mouth is a common symptom due to age, stress level, smoking, dehydration, mouth breathing, caffeine, alcohol, medication, medical condition, and chemotherapy. Erosion of the tooth surface will occur even faster if the mouth is dry. MI Paste will help restore the hardness of the enamel and reverse the erosion process.

The cream should be used until the dentist determines that the decay rate has stabilized, white spots disappear, and remineralization has occurred. Thereafter you can use the Trident products containing Recaldent to maintain the remineralized teeth. MI Paste can be purchased through your participating dentist or through Amazon.com.

If it is so wonderful, why doesn’t everyone use it? Well the need must be compelling and the cost is about five times more than an equivalent amount of over the counter toothpaste. There is one last thing about MI Paste. It is sweetened with xylitol.

Dr. Urban on Today’s Dentistry/Feeling tired all the time?

Does it seem like you go to bed early, get your eight hours of sleep and still feel tired? Perhaps you are not getting the sleep you think you are. Many of us suffer from obstructive sleep apnea or OSA.

Sleep apnea is characterized by pauses in breathing from a few seconds to a minute. These pauses can occur a few times during the night or over a hundred times an hour. It can allow a low oxygen saturation level in the blood resulting in oxygen starvation of the tissues and organs. It can result in strokes, hypertension, heart disease and death.

Sleep study tests can determine the incidence of breathing cessation. A medical doctor can confirm a diagnosis of sleep apnea after carefully reviewing the results of a sleep study test. These tests monitor the blood oxygen level, REM cycles, and the frequency of obstructive episodes per hour.

You can ask yourself these questions to see if you should seek help. What are my chances of dozing when I sit and read, watch TV, sit in public places, wait for red lights while driving or sit as a passenger in a car? What is the likelihood of falling to sleep after lunch? If you are tired or fatigued easily during the day it would be very prudent to consult with your physician for advice.

Sleep apnea can be initiated from the brain or from physical factors that obstruct and collapse the breathing space. Exactly where the collapse occurs in the back of the throat can determine the treatment alternatives.

Treatments for OSA can vary from anti-snoring devices made by dentists, sleeping on specially tilted pillows, neck slings, or wearing facemasks attached to positive pressure air pumps (CPAP). As with all treatment options these CPAP pumps cannot be tolerated by everyone and may have a limited success with some individuals.

In severe cases where respiratory arrest is possible surgery may be the only option. Surgical removal of excessive soft tissues in the throat and nasal sinus surgeries have been performed to open up the airways with limited success. In the most severe cases skeletal surgeries are performed to open up airways. This type of surgery, although extensive, has had great success. It sounds like a lot of treatment, but we are talking about a life-threatening situation if left untreated.

Regardless, I hope that you can appreciate that snoring may be a sign of a more serious problem and that it should be discussed with your physician or dentist. Your dentist can do a quick airway analysis, ask a few questions, and refer you to a physician that specializes in sleep apnea. Depending upon the results you may just have a snoring problem that can be alleviated with a simple appliance. Remember that OSA is not condition about a lack of sleep, but a medical condition about a lack of oxygen.

Dr. Urban on Today’s Dentistry/Oh No! Not another cold sore!

Cold sores are common lesions that typically occur outside of the mouth. The lips, chin, face, and nasal areas are most affected. They are caused by the herpes virus (a little different strain from genital herpes) and are very contagious. Once you get infected you have it forever. So now that you have it what do you do with it?
Let’s first discuss the infection process. Someone in your past inoculated you with the active herpes virus. I am sure it was unknowing and innocent. During this primary stage the virus could infect inside or outside the mouth and produce very painful blisters. The blisters will last from 3-21 days and then disappear. The virus will then enter a latent period where it calmly resides in the nerves only to be reactivated in the future and start the process all over.
It is very important not to pop and drain the blisters because they contain the virus. Even when the blisters are crusted over they will have the live virus. Keep your hands washed and do not share lip balms and towels and eating utensils. You can spread the herpetic sores to other parts of your body-so no scratching. Did I mention no kissing? Use the same common sense you would use during a flu epidemic.
We really have no real answer to what triggers an outbreak. It seems that sun exposure, stress, sickness, compromised immune systems, and lack of sleep may initiate an outbreak. Other times it seems the outbreaks just occur to mess with you-like before a vacation, senior prom, graduation or wedding.
The first sign of an outbreak is the tingling and itchiness. At this time it is advised to “freeze” the lesion with ice or overwhelm it with an antiviral drug like Famvir. Using a mega dose within the first hour of the outbreak will eliminate or reduce the severity and duration. We can’t all walk around with Famvir in our pockets so this chance of stopping it in the first hour is small.
The second stage is puffiness and blistering. Topical applications of antiviral creams may reduce the severity and possibly the duration. Other medications like Abreva , Blistex, and Zilactin allow you to tolerate the blister and keep it moist so it will be less likely to crack. Health food stores sell lysine lip ointments and drops and red algae capsules. I have personally used all of these methods with varying degrees of success. I am very impressed with the lysine and red algae supplements since they helped the most to shorten the duration. You have to evaluate your own outbreak to determine if the treatment would be of any value. In other words, sometimes we just have to deal with it and not spread it around to the nose or eyes.
Medical advice should be sought if the lesions do not go away in a couple of weeks or quickly return. Herpes infections can cause complications with eczema, compromised immune systems, organ transplants and deliveries of newborns.

Dr. Urban on Today’s Dentistry/Mouth Sores

Everyone has experienced mouth sores in their lifetime. Fortunately, the tissues of the mouth quickly heal and the lesions disappear. Let me briefly review the types of lesions that can occur and why you should be concerned.

Traumatic lesions such as lip and cheek biting, pizza burns, and gum scrapes are painful but short lived. The lesions are tender for about a week then heal over in the second week. During this time it is important not to re-injure the site and to avoid acid or astringent foods. Rinsing with warm water with a pinch of salt helps soothe and cleanse the wound. Topical use of benzocaine ointments (i.e. Orajel or Zilactin) gives temporary relief during the painful phase.

Traumatic wounds may become ulcerated. Ulcers are open wounds that have become infected. They may have a white border with a yellowish membrane over the middle. They are usually painful. Rinsing with prescription chlorhexidine to reduce the microbes in the ulcer and applying topical ointments are effective and will speed up recovery.

Blistering and sloughing are often associated with certain diseases. If some damage occurs to a component of the oral mucosa the layers can separate. This separation results in a blister. When a blister ruptures sloughing will occur and the area becomes ulcerated. These lesions may require topical or ingested steroids.

Swellings and growths can be the result of infections, reactions to a chronic stimulus, or a new unwanted growth (tumor). Your dentist should check these enlargements. Infections will usually respond to antibiotics and treatment or removal of the source of the infection. New rapid growths in the mouth should be evaluated to determine if it is serious or benign. Only a microscopic analysis can tell the nature of the growth so biopsies are often performed and the growth monitored.

Pigmented lesions are usually dark. A pigmented lesion may be the result of a small fragment of old filling that got trapped in the gums or cheek or from naturally occurring melanin pigmentation or blood vessels. These lesions should be checked. They can be an innocent convolution of capillaries or be a sign of a malignant melanoma or sarcoma.

An oral lesion can appear white due to the thickening of the keratin layer of the mouth (similar to a skin scab turning white when it is wet). The white patch (leukoplakia) will not rub off and it is difficult to predict its biology. Some form of biopsy is needed to determine malignancy. A white patch can remain the same or change over time and should be monitored by your dentist. Red lesions indicate a thinner keratin layer and may often have a burning discomfort. Red lesions associated with smoking are of great concern and all should be examined for pre-malignancy.

Your dental office will provide an annual oral cancer exam. Some practitioners are utilizing specially developed cancer screening tests to “see” through to the deeper layers of the mouth. These screens are very accurate and will give peace of mind that everything is okay for now.

Dr. Urban on Today’s Dentistry/Think Bacteria!

Why do some people have dental disease and others do not? Bacteria cause dental decay and gum disease. How each individual’s immune system responds to bacteria and the day-to-day care each of us gives to limit the effects of bacteria will determine who will be at risk for developing dental diseases.

First, we all have bacteria in our mouths and it is impossible to sterilize your mouth. Second, there is no drug or antibiotic that will cure dental decay or gum disease. Maybe some day there will be, but not at the present. Let us see why this is so.

Research into both types of major dental disease has isolated over 32 types of bacteria that can cause dental decay and even more bacteria that break down the gum and bone structures that hold the teeth soundly in place. To compound the problem the list of bacteria keeps growing every few years as scientists continue their research. This means that dentists and dental hygienists look to prevention rather than a cure to limit the damaging effects of the millions of organized bacteria that burrow into the teeth and gums.

I haven’t seen any literature that states that bacteria do this on purpose or that they even have a brain. However, all living matter seems to have a will to exist and propagate. The damage occurs when too many unchecked bacteria overwhelm the hardened tooth structure and the immune system that protects us. The dental decay causing bacteria thrive in an acidic environment and the acids produced by them will eat away at the tooth enamel. The bacteria associated with the gums will generate a battleground of bacteria vs. immune cells. Bleeding, puffy gums, and bone loss are signs of this battleground.

If you desire to maintain the health of your teeth and gums you must help your immune system overcome this invasion. First, limit the food source. This means removing any easily digested foods-like sugar-from the teeth. Remember that bacteria can divide into two bacteria in twenty minutes. They need something they can eat and digest really fast.

Second, brush each tooth for five seconds (about 2 minutes for the whole mouth). Floss or use special brushes between the teeth. This is most important. In my experience most dental disease occurs in these areas. Your hygienist or dentist may prescribe special toothpastes and oral rinses to help.

Third, try to maintain a healthy diet. Bacteria love junk food and sugar-our bodies do not. Limit the consumption of fruit juices and sodas. These beverages will make the mouth acidic and help to grow the harmful bacteria.

Fourth, see your hygienist on a routine schedule. This may vary from every three months to just annual visits. Your dentist will recommend a personal schedule depending upon your needs. Dental disease is chronic and mostly slow in nature. It will take a lifetime of good oral care to minimize the amount of dental work.

Dr. Urban on Today’s Dentistry/Save teeth or replace with implants?

If you have a severely broken down tooth, how does your dentist determine the type of treatment with the most favorable outcome? The decision is not always easy or clear cut. If your dentist saves a tooth how long will it last? If the tooth is removed what will be the replacement? These are the choices and each choice has consequences.

Suppose a decision is made to save your tooth with a root canal treatment. A root canal treatment is basically a long filling that seals the tooth from being an avenue for bacteria to enter the bone and bloodstream. A tooth treated in this way need a filling or crown to hold it together and to protect the root canal filling material that is placed inside.

Over time the root canal treated tooth becomes dehydrated and brittle. It is susceptible to fracture, recurrent leakage, and failure. Although the treatment was 100% successful the tooth can eventually fail anyway. This may take many years. So if the tooth may fail why not just extract it and place an implant? Remember that most teeth treated in this way last from 7-20yrs (or longer). In other words its useful life expectancy was longer than that of most automobiles. The fee range for this service is about $2500.

Suppose a decision is made to replace with an implant-supported tooth. Implants are titanium (a most biocompatible material) inserts placed into the dental bone. A metal top (abutment) is screwed onto the implant (no anesthetic is necessary) and a crown made over the metal top. Although this process takes many months I have been very pleased with the minimal discomfort experienced during this process. Implant placements have reached a 98% success rate. Conceivably once the implant “takes” it can last a lifetime if proper home care is used. The cost for this procedure is about $3700-$5000 per tooth.

Implants can fail from breakage in one of the components, bacterial disease, or loss of bone around the implant. If 98% succeed, then two out of a hundred do not and the procedure has to be repeated.

There is an argument that can be made whether we should save a tooth at all costs or extract and place an implant. Are root canal teeth “implants in training” as one of my colleagues says? Over many years the cost difference will have been erased with the increased longevity of the implant. Furthermore, once the root canal treated tooth is ultimately removed it will need replacement. Would it be better to extract sooner than later? This depends upon you, your financial wherewithal, and your dentist.

In my practice I like to preserve teeth as long as possible. I know that I will not be the only dentist over a person’s lifetime and I try to save as much as possible for future dentists. I believe that dental technology and biologic research may ultimately make both root canal treatments and implants a thing of the past.

Dr. Urban on Today’s Dentistry/The Oral Exam

What is your dentist observing when performing an oral examination?

As a kid I always thought that my dentist was trying to make holes in my teeth with that little pokey thing. As I later found out that was impossible. My dentist was merely trying to detect small soft decaying spots on the chewing surface of my teeth. (Sorry Dr. Parker.)

Dentistry involves more that checking teeth. Dentists check the health of the supporting structures that keep teeth locked in solid and we look for any soft tissue changes or abnormalities that could lead to serious consequences later on.

Your dentist may require you to update your health history at regular intervals. I recommend annual updates or notification of any change of medications or health status.

The soft tissue exam will start with a visual inspection of the face, skin, lips, cheeks, tongue and floor of the mouth. The dentist or hygienist will gently pull the tongue from side to side and check the floor of the mouth for any lumps. Some dentists have invested in specialized equipment to screen their patients for early invisible cancer growths. If positive signs are noted then more diagnostic tests may be necessary. Why is this important? The death rate in the United States for oral cancer is higher than that of cervical cancer, Hodgkin's disease, cancer of the brain, liver, testes, kidney, or ovary.

The doctor will check the condition of your bite and look for any sign of damage to the TMJ. The TMJ is the hinge joint area that allows your jaw to move. Clicking or even popping may be more than an annoyance and lead to more devastating joint damage. Specialist referral or treatment with a night guard may be the next step. If the bite is off or teeth are crowded you may get a referral to the orthodontist.

The periodontal exam concentrates on the gum area around the teeth. The gums should be firm and pink. They should not bleed or ooze pus. They should not be abraded and receded away from over aggressive brushing or swollen from brushing neglect. The color and texture of the gums, any tooth mobility, gum recession, and bone loss will be noted. The hygienist will measure the gap between your gums and where they attach to the tooth. This is the “pocket” and normal healthy pockets are 2-3 mm deep. Beyond that depth and cleaning becomes difficult. The best tooth brushing and flossing techniques will not go below 3mm.and clean the deeper pockets.

Finally, the oral exam will involve checking the teeth. The list of dental conditions includes decay, white spots, abrasion, erosion, attrition, abnormal wear, fractures, cracked fillings, leaky crowns, bad fitting removable bridges and dentures, and loose bridges. Periodically, x-rays will be taken and examined for decay between the teeth, bone loss around the teeth, abscesses, cysts, and tumors.

Your dentist and hygienist are very sensitive to spotting abnormal signs. However, if you notice anything not right please inform your dental team.
