Research shows that babies are born without any harmful bacteria in their mouths. However, once bacteria colonize in the mouth, children are more prone to cavities in their baby teeth and permanent teeth. How do they get the bacteria? Caregivers.

Most parents don’t know that they can pass harmful bacteria from their mouth to their baby’s mouth. The most critical time is during the child’s first 2 ½ years of life. Most children are born without a single tooth. Can bacteria passed to children without teeth affect their decay potential for their whole life? According to research the answer is yes.

Here’s a shocker…..If you have a history of poor oral health, including many fillings in your mouth, you are much more likely to transfer these harmful bacteria to children. How? Typically, this takes place through common parental or caregiver behaviors such as sharing utensils or cleaning a baby’s pacifier with your own saliva.

Prevention starts as early as 6 months into a pregnancy. Research shows that expectant mothers who chewed gum containing the sweetener xylitol are much less likely to have decay-causing bacteria in their saliva. So, take-home point number one, it is essential for expectant parents and caregivers to keep their own mouths healthy. If you reduce the bacterial levels in your own mouth, you are not only benefiting yourself but also that of your unborn child. Visiting a dentist regularly, even more often when you are pregnant, improving your homecare, and using products that specifically reduce bacteria are all essential.

Your baby is born; now what? First, eliminate potential ways of transferring saliva to your baby. Do not share utensils or let grandma or grandpa lick a cloth to clean around a baby’s mouth. Wiping your baby’s gums with a clean cloth after meals is also good practice to help reduce bacterial levels.

Once a child starts getting teeth, diet plays a significantly greater role. Minimizing snacks and drinks with fermentable sugars is key. This starts with the bottle. Bottle syndrome, also known as baby bottle tooth decay, occurs when teeth become exposed, at length and frequently, to liquids containing a form of sugar. All liquids that contain sugar can cause bottle syndrome, including breast and cow’s milk (which contain the sugar lactose), formula, fruit juice (which contains the sugar fructose), soda and other sweetened drinks. It is caused by the constant presence of milk, formula, or fruit juice in a child’s mouth during the night, during breastfeeding, during naps, or for extended periods during the day. The liquid pools around the teeth and gums, providing food for the bacteria in plaque. The bacteria produce acid as a byproduct when they consume the sugar. This acid attacks your child’s teeth and causes decay.

When your child feels comfortable with a toothbrush, brush their teeth and gums twice a day with an extra-soft toothbrush. Use a pea-sized amount of toothpaste without fluoride until your child is old enough to spit.  If your child doesn’t like toothpaste, it’s fine to brush without it.

Prevention starts before babies are born. It starts with taking care of your own mouth.

The winter season is a time that many people look forward to because it means holidays spent with family and friends and making fun memories, but for your mouth, the cooler months can be challenging. Winter mouth issues are extremely common, and your dentist in Rowley has some tips to share to help you combat the struggles you may experience this season.

Last year I wrote a column about a study I saw in an article from over a decade ago. It was about the poor odds people have making changes in their life actually happen. The article was an outpouring of concern from healthcare experts and doctors, all looking for a way to change the behavior of people who love their lifestyle so much that they were willing to literally die from it.

In the Johns Hopkins study, 9 of 10 heart surgery patients chose to return to their unhealthy lifestyle, rather than make the changes needed to live longer. Very few were convinced by their doctors to make radical daily changes.

Based on my own experiences trying to move individuals to change habits that are having negative effects on their oral health, I knew it was difficult, but was shocked by the 90% statistic, especially relating to a do or die scenario. There are two studies that I have seen relating specifically to dentistry which confirm that changing behavior is not easy.

The first study looked at whether dental hygienists were as effective as they thought they were with oral hygiene instructions. The role of the dental hygienist is to instill the need, desire and ability for patients to achieve optimum oral health. The purpose of this study was to determine if patients correctly understood oral hygiene instructions provided by the hygienist, and to see if the hygienists felt that they were giving patients individualized instructions.

No big surprise, the findings showed a disconnect between what the hygienists believed they were conveying to their patients, and what the patients actually heard. So, part of the problem with getting people to change starts with actually confirming that the person understands the call to action and the implications of not acting.

The second study was to determine if a simple follow-up contact with the patient would impact behavioral change. In this study, patients had a routine dental hygiene appointment and were given specific oral hygiene recommendations based on their individual needs. Contact was then made with patients one week after their appointment.

The patients were asked if they tried the specifically recommended products they had been instructed to use, if they liked using them, and why or why not. Only 50 percent of the patients replied to the call-out from their hygienist. Of those who did respond, most said they tried the specifically recommended product, but only 33 percent of them felt that they would continue to use it. The conclusion of the study was that follow-up contact alone is not an effective method to change behavior and does not increase compliance with oral health recommendations.

So, what does it take to get people to change their habits? I think it is safe to say that some will and some won’t, no matter the consequences. It is also safe to say that it is a choice.

Do you have any problems with dental decay (cavities), gum recession, and/or dental erosion (the chemical breakdown of tooth structure)? These dental issues are complicated multifactorial diseases of epidemic levels affecting both children and adults. A healthy mouth sometimes requires more than brushing, flossing, and “fillings”. With current scientific evidence and new technologies, patients and practitioners need to begin to look at these problems not just from a drilling and filling approach, but also from a medical (preventive/therapeutic) approach.

There are over 19,000 different bacteria that have been found in mouths and every person has about 1,000 different types. Not all of them cause decay, but many of them have also been found to grow on artery walls. The medical/dental systemic connection is real and we must pay more attention to it.

Why the increase in decay? Most of it has to do with dietary trends. We snack more, eat more sugar/carbs, drink more soda, have more gastric reflux, take more mouth-drying medications, etc. Dental caries (decay) is a pH specific disease. The right bacteria, plus sugar, create acid which breaks down the enamel of the teeth. Add an already acidic environment and it is even worse. In most cases it is a preventable disease. And don’t think that just because you don’t eat “sugar” that you are safe. If you are getting decay, something is causing it. The problem is that changing behavior can be very hard to do.

It is time for the dental professional to take a different approach when treating this disease. More focus needs to be shifted to prevention of decay rather just treating it. Filling teeth is treating the result of the disease, but does nothing to prevent it. The dentist needs to take a more active role in assessing individual’s risk factors. In the dental world this is referred to as CAMBRA, which stands for Caries Management By Risk Assessment.

Based on assessing an individual’s risk factors, such as quality of home care, quality of salivary flow, medication issues, and dietary issues, a caries-preventive strategy can be established. There are many new products on the horizon to help combat and virtually eliminate this disease. However, dentists must take some responsibility and be open to a different management of this disease. They must also be able to motivate people to change habits, which can be challenging. The bottom line is that if you want to be decay-free, you can be.

For those at higher risk, there are some great products currently available from a company called Carifree. Everything from new toothpastes and gels with ions in them to rebuild tooth structure, sprays to neutralize pH, and probiotics are on their way. Right now you can use things like the sweetener replacement Xylitol, which by itself is cavity-fighting, but also works synergistically with fluoride. Prescription level toothpastes are also available, and there is strong research for the topical application of fluoride varnish, the same stuff the kids get, for adults.

The evidence is very clear – this is a preventable disease. Next time you go to the dentist and find out you have a new cavity, stop blaming the dentist or yourself, and ask to get a specific protocol for prevention of this disease, based on your specific risk factors. You may also want to mention Carifree products to your dentist in case they have not heard of this company.

It seems I have more and more patients telling me about their upcoming shoulder, hip, and knee replacement surgery. There are other parts that people have replaced, but those are the top three. Most of these people decide to go under the knife to improve their quality of life.

If you were born in the Paleolithic era, you could expect to live to 33 years old. The average global life expectancy in 2010 was more than double this number at 67 years. The main reasons for this are advances in hygiene, food production, and medical care.

On the bright side, if you were born in the Paleolithic era, you would most likely never need a hip replacement. It usually takes longer than 33 years to wear out the joint.

Today, about 2.3% of Americans have had a hip replaced and 4.6% have had a knee replaced. More than a million joint replacements will be done this year and the number continues to grow. The longer we live, the more chance we have of parts needing replacement.

What about teeth? Your lower first permanent molars erupted into your mouth around the age of 6 years old. If you are 50 years old, these teeth have been tolerating chewing, hot coffee, cold ice cream, the occasional popcorn kernel, and maybe even grinding back and forth for 44 years. You have used them every day for 44 years!

What else can you use that much for 44 years that doesn’t require some kind of maintenance? How about that car you drive every day? The car certainly requires maintenance to function properly. The oil needs to be changed on a regular basis. Depending on several factors, the tires need to be rotated to wear evenly and usually need to be replaced after so many miles. I don’t know too many people who drive the same car for 44 years.

Of course, I am not insinuating that everyone needs replacement teeth at some point.  I am saying that it is naïve to think that a car, a furnace, a computer, or your teeth will run forever without maintenance, and that they will run better with routine maintenance.

What happens if you don’t do regular maintenance on your car? It will run for a long time, at some point its performance will decrease, and then when it finally decides to quit, it will be catastrophic. You will have to replace your car. How much will it cost to replace your car? Doesn’t it make sense to keep up with the routine maintenance?

Sometimes, even with regular maintenance, parts need to be repaired or replaced. We often have to make a decision on “how” to fix something. Do we patch it up to get some more miles out of it or do we replace the part to extend the serviceability? It may depend on the cost. It may also depend on the risk of the patch failing. You may decide that the risk is too high and go ahead and replace the part, even though it may cost more.

If you were a caveman, we wouldn’t be discussing this. You wouldn’t have a car and most of your own “parts” would make it to your expected 33 years….but you’re not a caveman. You are likely to wear parts out. You may need a hip replacement, or a filling, or a crown.

And remember: Regular oil changes and maintenance will help your car run well much longer.
