In our previous newsletter, we cited many scientific studies to show the link between gum infection and systemic diseases.  In this newsletter we will be discussing the Treatment of Gum Infection, Perio Maintenance, and Prevention of Gum Infection. 

Treatment of Gum Infection

The primary goal of periodontal treatment is to clear infection from the gums and teeth.  Periodontal infection is a chronic and non-curable bacterial infection. The traditional deep cleaning technique tries to clean the pockets forming between the gums and teeth due to infection. This method had been working very well but also had its limitation.

One thing one must understand is that infected periodontal pockets have two walls: tooth side and bone-gum side (Figure 1)The deep cleaning treatment utilizes scalers to physically scale and clean the teeth side of the infected pocket.  However, bacteria has also penetrated and destroyed the gum and bone surrounding the infected teeth.  Adjunct treatments such as medication and laser help to reduce and remove infection in the gum and bone side.  The idea here is to create two clean sides (tooth side and bone-gum side) which ensure that no bacteria are trapped during the healing phase.

Perio Maintenance

What is the difference between perio maintenance and a regular cleaning?  Why do I need to have cleanings more often (every 3-4 months)? These are questions that are routinely asked by our patients. The perio maintenance program is designed to help patients with history of gum infection.  The general rule is, if you already have a history of gum infection, which causes the change of the bone level supporting your teeth, then you need to get cleanings more often.  

During routine home care with the proper cleaning technique, patients can clean up to 3 mm below the gum line.  If you had gum infection in the past, most likely you would have some areas of the gum that are deeper than 3 mm due to the history of bone loss.  These areas need to be cleaned out by the hygienist with special tools.  Cleanings every 3-4 months are required in these cases to prevent infection from starting again.  Just imagine you have some areas in your mouth with food stuck in there and rotting out for 3 months.  Since you cannot clean past 3mm depth of gum, the hygienist has to do that for you every 3-4 months.

For a regular cleaning, a patients gum depth is less than 3mm, there’s no bleeding, and can maintain an excellent hygiene routine at home.  Cleanings every 6 months are recommended at this stage of oral health.

Prevention of Gum Infection

Promptly removing foods in between your teeth is the goal of brushing and flossing to help in preventing gum infection.  How often one should brush and floss really depends on how often one eats in a day.  Routine dental care with your dentist and hygienist is a must.  Our body is a very sophisticate machine; however, just like our car, we need tune-ups regularly to keep our body functioning properly for many years to come.

A recent literature review article has showed the strong connection between gum infection (periodontal disease) to other systemic diseases. In this newsletter, I will help to explain some common links between patients’ bleeding gums to their overall health.

Periodontal disease is the infection of the gum, teeth, and bone that surround teeth. Current estimates show that 75% of North American population has some form of gum infection[1]. Normally these are a low-grade chronic infection, which does not show any signs and symptoms besides occasionally bleeding of the gums and teeth while brushing and flossing. Due to the lack of symptoms, gum infection is usually undiagnosed or untreated.

Chronic inflammation response of the gum and bone surrounding the teeth cause the total body inflammation response to increase overall. This heighten inflammatory response contributes directly to worsening of systemic diseases which are caused by inflammation such as rheumatoid arthritis, osteoporosis, and pneumonia.

Inflammation factors from the gum also causes dislodging of fatty deposits in the blood vessel. These dislodged fatty deposits will travel through the blood system, which could block a blood vessel at the heart causing a heart attack or block a blood vessel in the brain causing a stroke.

Periodontal Disease and Alzheimer’s Disease

There is evidence that periodontal disease may be a risk factor for dementia through the bacterial and viral infections commonly found in periodontal disease. Oral infection can either directly or through systemic signals to the brain contribute to the development of Alzheimer’s disease[2].

Periodontal Disease and Cancer

Periodontal disease also have strong link to several type of cancer such as oral cancer, upper GI and gastric cancers, pancreatic cancer, lung cancer, and esophageal cancer[3].

Periodontal Disease and Diabetes

The association between diabetes and inflammatory periodontal diseases has been studied extensively for more than 50 years. Large evidence research shows that diabetes is associated with the increase in gum infection. Also periodontal disease can also adversely affect the metabolic control of diabetes. Patients with diabetes who have periodontal disease have two chronic conditions, each of which may affect the other, and both of which require frequent professional evaluations by health care providers[4].

Periodontal Disease and Premature Birth

The oral cavity works as a continuous source of infectious agents, and its condition often reflects progression of systemic pathologies. Periodontal infection happens to serve as a bacterial reservoir that may exacerbate systemic diseases. Research suggests that the bacteria that cause inflammation in the gums can actually get into the bloodstream and target the fetus, potentially leading to premature labor and low-birth-weight babies[5].

The common links of these systemic diseases to gum infection are bacteria in the blood and infl­ammation factors that produce by-chronic infection on the gum and teeth. The consequences of untreated gum infection often time would lead to serious health implications and the loss of multiple teeth. Scheduling a periodontal evaluation with your dentist is the first step to fight this silent deadly disease.

The Fight Against Cavities…

Why do I get cavities on my teeth?

Over the last 10 years while practicing dentistry, I realized that a lot of confusion comes from our patients when it comes to the question “Why do I get cavities on my teeth?” 

“Is it from too much candy, soda, soft teeth, or a combination of all these reasons?”

The science on how we get cavities has been well studied and documented. Cavities or decay on our teeth cause by bacteria byproducts. In a more simplified concept:

Cavity formation

  • Sugar from our food = Bacteria food.
  • Bacteria eats sugar and produces a byproduct = Acid content.
  • Acid produced by bacteria destroy our teeth and create a hole on our teeth = Cavity.

When do I need to fix my cavities?

Let’s review the anatomy of the tooth before I answer the above question.

The tooth has 3 parts: Enamel, Dentin, and Nerve.

Enamel, Dentin, Nerve


Enamel is the hardest part of the tooth and also there are no pain receptors in the enamel.  Dentin is the soft part of the tooth and is also the alive part of the tooth. The nerve chamber is where the nerve and blood vessels bring in nutrients to keep the tooth alive.

When a cavity starts, it has to break through the enamel part.  Since this is the hard part of the tooth, it may take many years for the cavity to break through.  Usually at this state, the patient won’t feel anything due to lack of pain receptors in the enamel layer.

Eventually the cavity will get to dentin layer.  At this state, the cavity starts to change its color to brown or black due to the natural yellow color of the dentin layer.  Since dentin is the alive part of the tooth, the patient starts feeling sensitivity on the tooth with the cavity especially to sweet, sour, or cold food and drinks.

If the cavity is left untreated, it will end up reaching the nerve.  Once the cavity reaches the dentin it begins to grow very fast.  Since the dentin is the soft part of the tooth, the cavity can grown and hit the nerve in only a few short months.  Patients will experience extreme pain when the cavity hits the nerve.  Symptoms range from sensitivity to hot and cold drinks, sharp spontaneous pain, constant dull aching pain, to extreme pain, which gets worse when lying down.  Once this happens it is already too late to do a filling.

The best time to fix your cavity is when it is still in the enamel layer.  However, most patients only visit the dentist when they start feeling something hurt.  By the time cavity starts cause some discomfort, it is already in the soft part to the tooth.  At this point, we only have a few months to fix the cavity before a full blown toothache arrives.

So the best answer is to keep up with your 6-month appointment so the doctor can catch the cavities early; when a cavity is diagnosed, we need to fix it ASAP.

3 Common Oral Health Myths Busted!

Myth 1: Bleeding gums are normal.


 Busted: If you washed your hands and they bled, would you be concerned? Of course! The same goes for your gums. Bleeding is the first sign of infection. Gums bleed because plaque, which is full of disease-causing bacteria, is accumulating where a toothbrush cannot reach to remove it. This is why flossing daily is so important. It reaches these areas, about 35% of your tooth surface, that tooth brushing misses, no matter how well you brush. The longer the bacteria accumulates, the stronger it gets, which causes more than just bleeding and inflammation. This bacteria can cause your gums and bone that hold your teeth in place to break down, and they don’t grow back. Also, when plaque sits undisturbed it can harden, causing more irritation to your gums and providing a home to this virulent bacteria. At this point it is called calculus or tartar, which can only be removed by a dental hygienist. This is why regular dental appointments are more than just checking for cavities! Not great at flossing? Be honest with your dental hygienist about it. Your hygienist can show you other options such as interdental brushes, water flossers, or simply showing you the correct flossing technique. Once you begin flossing, your gums may continue to bleed for a while; this is your body’s immune response trying to fight the infection. So keep at it daily!

Myth 2: If Your teeth don’t hurt, they are healthy.

Busted: Many dental problems, such as chronic gum disease and cavities, don’t hurt in the beginning stages. It’s once they have progressed to a point where treatment is quite extensive, not to mention expensive, that you actually feel them. For instance, a cavity tends to only hurt once it has reached the center of the tooth where the nerves are located. At this point, a filling won’t simply take care of the problem. Most times you may need a root canal and a crown, if the tooth can be saved at all. This is why detecting problems early, with X-rays and regular dental visits, is so important. Dentists and dental hygienists are highly trained to know when you need X-rays. Dental X-rays are imperative to diagnose potential problems, to check for cavities, and to monitor your bone level holding your teeth in place, among other things. Without them your dentist and hygienist are working blindly. You wouldn’t want a broken arm to be set without an X-ray to determine the extent of the fracture, right? Same goes for your teeth.

Myth 3: Oral health doesn’t affect overall health.

Busted: Your mouth is connected to your body! In fact, many diseases can show their first symptoms in your mouth. This includes some autoimmune diseases and even HIV. Further, you are swallowing the bacteria in your mouth every day, all day. If you have gum disease, this bacteria can be harming more than just your mouth. Bacteria can enter your bloodstream and affect other organs in your body. Research is emerging every day showing links of bacteria from the mouth contributing to heart disease and stroke risk to rheumatoid arthritis, pre-term and low birth weight babies, even Alzheimer’s disease and the ability to control blood sugar levels in diabetes. Infection in your mouth = problems for your whole body, so take care of your mouth!

Brushing Before or After Food And Drinks

Little girl brushing her teeth

   Have you ever been told to brush your teeth before you eat? Probably not, but according to a recent article it is suggested that it would be better for your teeth (Nathan J). One of the biggest reasons to brush before you eat would be to avoid enamel or dentin erosion. When you eat most foods, or drink beverages like coffee, soda, or juice the pH of your mouth becomes more acidic. The more acidic your mouth is, the “softer” you tooth surface, the more likely tooth erosion happens when you brush. Brushing before you eat removes the plaque and biofilm that is made up of bacteria waiting to be feed by the food you eat. Once that bacteria starts to metabolize the food in your mouth, the acidity of your mouth is increased (Pradhan D, Jain D, Gulati A) leading to “softer” tooth surface.

   One reason that most people might not want to brush before they eat is the taste of food from brushing with toothpaste. Brushing without toothpaste could be an option for some, although I would recommend using fluoride mouth rinse not only to keep fluoride in your oral hygiene routine but to aid in removal of food particles. If brushing before you eat doesn’t sound like something you would want to try, waiting at least 1.5 hours after you eat or drink before brushing your teeth can help minimize tooth wear (Nathan J). I believe that for those with gum recession, worn enamel such a toothbrush abrasion, or even those who have tooth sensitivity, brushing before you eat might really be beneficial.

Reduce Tooth Loss With A Little Floss!

Dental Floss

    The Holidays are over and it’s time to start the new year! With all the New Year’s resolutions that we demand of ourselves, one resolution that we should include is to develop healthy habits. This New Year resolution or goal doesn’t have to be a big goal. You can just start with something small including with your oral health. Developing small habits to keep your teeth and gums healthy will benefit your overall health in a big way. Flossing is a habit that everyone should and needs to partake on. I know that as a health care provider, we can not stress this enough and I’m sure as a patient, you already heard of flossing enough. I find that most patient’s that do not floss is not because they don’t know how or don’t know what floss is, but it’s really because they haven’t made it a habit long enough to make it part of their daily hygiene routine. Yes, in the beginning, including flossing into your routine will be a little difficult but if you take these baby steps, it will get much easier. 
    Tips of making flossing part of your oral hygiene routine would be to floss first then brush your teeth. The tooth brush can not reach in certain areas so whether you floss before or after, it really doesn’t matter just as long as you do it.If you floss twice a day, three times a day, or every other day, make it a goal to add another day into your flossing schedule until it becomes a daily habit.Another tip, is to carry floss with you. Everyone is always on the go these days, so on your down time, for instance while waiting at a stop light, take out your floss. I know, its not the ideal place to floss but most peoples’ excuse of not flossing is because they were in a hurry or too tired to floss, so hey floss when you can as long as you’re doing it. Of course, if flossing seems difficult to do, they are other tools that we can use like proxy brushes to clean between teeth and gums to keep your mouth healthy. Developing this habit will not only keep you from developing periodontal disease or cavities, but it can also prevent your body from getting other diseases such as heart disease. Your body will thank you and your love ones will thank you too. Happy New Year and remember, “reduce tooth loss with a little floss.” 🙂

Lets talk about braces…


What is orthodontic treatment?

Orthodontic treatment or commonly known as “braces treatment” is a treatment focused on correcting teeth and facial irregularities. The result of orthodontic treatment is a dramatic beautiful smile, stable and improved dental health and enhances quality of life for many people of all ages.  Teeth and facial irregularities known as malocclusion (Bad Bite) could result from genetic and environmental factors.

Malocclusion (bad bite) of teeth is a misalignment problem that can lead to a serious oral health complications. Bad bite is when there is difference in the size of the top and bottom jaw.  When the upper jaw is bigger than the lower jaw, it is called an overbite.  When the lower jaw is bigger, it is called underbite. When teeth are crooked because of inadequate jaw space, it is known as overcrowding.  Teeth are not able to perform vital functions if they are misaligned.  Most people with mild malocclusion will not require any treatment. However, long term function with severe malocclusion can result in excessive early wear of teeth, tired muscle or jaw pain, and headaches.

At what age should braces treatment be started?

This is the most common question our doctor received during the last sevens year providing braces treatment for adult, adolescents and children.  Braces treatment could start at any age as soon as a problem is detected.  The American Association of Orthodontist recommends a child should have orthodontic evaluation at the age seven.  At this age issues such as an uneven bite, overcrowding, underbite, and/or damage by oral habits will become apparent. Starting process early does not mean a child will get braces right away.  It just mean the Doctor would be able to detected any potential problem early and decide the best time to start treatment.

What is the benefit of starting treatment early in children instead of waiting till adulthood?

Early detection and the treatment of malocclusion of teeth in children will reduce the duration of treatment, and also make it less expensive.  In some case, early treatment can help avoid extractions (removal of adult teeth) or a large problem that requires jaw surgery as the mean for correcting malocclusion in adulthood.

Adults can also get good results.  However, treatment for adults will generally take longer and will be more expensive.  The earlier you treat malocclusion, the better the outcome.

How much do braces cost?

The costs for braces treatment vary depending on how severe the bad bite is and the time required treating it. Treatment typically lasts from 6-36 months.  Proper diagnosis requires taking x-rays and photos which enable our doctor to make informative decisions about the form of treatment necessary. We offer complimentary braces consultation if you have any question.
