Answers to Our FAQs - San Jose Pediatric Dentistry - Ralph Zotovich, DDS 

Bad breath (halitosis) can be an unpleasant and embarrassing condition.  Many of us may not realize that we have bad breath, but everyone has it from time to time, especially in the morning.

There are various causes that attribute to bad breath, but in healthy people, the major source is microbial deposits on the tongue.  Some studies have shown that simply brushing the tongue reduced bad breath by as much as 70 percent.

What causes bad breath?

• Morning time – Saliva flow almost stops during sleep, reducing its cleaning power and allowing bacteria to grow, which results in bad breath.
• Certain foods – Garlic, onions, etc.  Foods containing odor-causing compounds enter the blood stream; they are transferred to the lungs, where they are exhaled.
• Poor oral hygiene habits – Food particles remaining in the mouth promote bacterial growth.
• Periodontal (gum) disease – Colonies of bacteria and food debris residing under inflamed gums.
• Dental cavities and improperly fitted dental appliances – May also contribute to bad breath.
• Dry mouth (Xerostomia) – May be caused by certain medications, salivary gland problems, or continuous mouth breathing.
• Tobacco products – Dry the mouth, causing bad breath.
• Dieting – Certain chemicals called ketones are released in the breath as the body burns fat.
• Dehydration, hunger, and missed meals – Drinking water and chewing food increases saliva flow and washes bacteria away.
• Certain medical conditions and illnesses – Diabetes, liver and kidney problems, chronic sinus infections, bronchitis, and pneumonia are several conditions that may contribute to bad breath.

Keeping a record of what you eat may help identify the cause of bad breath.  Also, review your current medications, recent surgeries, or illnesses with your dentist.

What can I do to prevent bad breath?

• Practice good oral hygiene – Brush at least twice a day with an ADA approved fluoride toothpaste and toothbrush.  Floss daily to remove food debris and plaque from in between the teeth and under the gumline.  Brush or use a tongue scraper to clean the tongue and reach the back areas.  Replace your toothbrush every 2 to 3 months.  If you wear dentures or removable bridges, clean them thoroughly and place them back in your mouth in the morning.
• See your dentist regularly – Get a check-up and cleaning at least twice a year.  If you have or have had periodontal disease, your dentist will recommend more frequent visits.
• Stop smoking/chewing tobacco – Ask your dentist what they recommend to help break the habit.
• Drink water frequently – Water will help keep your mouth moist and wash away bacteria.
• Use mouthwash/rinses – Some over-the-counter products only provide a temporary solution to mask unpleasant mouth odor.  Ask your dentist about antiseptic rinses that not only alleviate bad breath but also kill the germs that cause the problem.

In most cases, your dentist can treat the cause of bad breath.  If it is determined that your mouth is healthy and bad breath remains persistent, your dentist may refer you to your physician to determine the cause of the odor and an appropriate treatment plan.

Brushing and flossing help control the plaque and bacteria that cause dental disease.

Plaque is a film of food debris, bacteria, and saliva that sticks to the teeth and gums.  The bacteria in plaque convert certain food particles into acids that cause tooth decay.  Also, if plaque is not removed, it turns into calculus (tartar).  If plaque and calculus are not removed, they begin to destroy the gums and bone, causing periodontal (gum) disease.

Plaque formation and growth is continuous and can only be controlled by regular brushing, flossing, and the use of other dental aids.

Toothbrushing – Brush your teeth at least twice a day (especially before going to bed at night) with an ADA approved soft bristle brush and toothpaste.

• Brush at a 45 degree angle to the gums, gently using a small, circular motion, ensuring that you always feel the bristles on the gums.
• Brush the outer, inner, and biting surfaces of each tooth.
• Use the tip of the brush head to clean the inside front teeth.
• Brush your tongue to remove bacteria and to freshen your breath.

Electric toothbrushes are also recommended.  They are easy to use and can remove plaque efficiently.  Simply place the bristles of the electric brush on your gums and teeth and allow the brush to do its job, several teeth at a time.

Flossing – Daily flossing is the best way to clean between the teeth and under the gumline.  Flossing not only helps clean these spaces, it disrupts plaque colonies from building up, preventing damage to the gums, teeth, and bone.

• Take 12-16 inches (30-40cm) of dental floss and wrap it around your middle fingers, leaving about 2 inches (5cm) of floss between the hands.
• Using your thumbs and forefingers to guide the floss, gently insert the floss between teeth using a sawing motion.
• Curve the floss into a “C” shape around each tooth and under the gumline.  Gently move the floss up and down, cleaning the side of each tooth.

Floss holders are recommended if you have difficulty using conventional floss.

Rinsing – It is important to rinse your mouth with water after brushing, and also after meals if you are unable to brush.  If you are using an over-the-counter product for rinsing, it’s a good idea to consult with your dentist or dental hygienist on its appropriateness for you.

Over the years, there has been some concern about the safety of amalgam (silver) fillings. An amalgam is a blend of copper, silver, tin, and zinc, bound by elemental mercury.  Dentists have used this blended metal to fill teeth for more than 100 years.  The controversy is due to claims that the exposure to the vapor and minute particles from the mercury can cause a variety of health problems.

According to the American Dental Association (ADA), up to 76% of dentists use silver containing mercury to fill teeth.  The ADA also states that silver fillings are safe and that studies have failed to find any link between silver containing mercury and any medical disorder.

The general consensus is that amalgam (silver) fillings are safe.  Along with the ADA’s position, the Center for Disease Control (CDC), the World Health Organization, the FDA, and others support the use of silver fillings as safe, durable, and cost effective.  The U.S. Public Health Service says that the only reason not to use silver fillings is when a patient has an allergy to any component of this type of filling.  The ADA has had fewer than 100 reported incidents of an allergy to components of silver fillings, and this is out of the millions of silver fillings placed over the decades.

Although studies indicate that there are no measurable health risks to patients who have silver fillings, we do know that mercury is a toxic material when we are exposed at high, unsafe levels.  For instance, we have been warned to limit the consumption of certain types of fish that carry high levels of mercury in them.  However, with respect to amalgam fillings, the ADA maintains that when the mercury combines with the other components of the filling, it becomes an inactive substance that is safe.

There are numerous alternatives to silver fillings, including composite (tooth-colored), porcelain, and gold fillings.  We encourage you to discuss these options with your dentist so you can determine which option is best for you.

You should have your child's teeth checked and cleaned at least twice a year, though your Pediatric Dental Specialist. 

Regular dental exams and cleaning visits are essential in preventing dental problems and maintaining the health of your child's teeth and gums.  At these visits, your their teeth are cleaned and checked for cavities.  Additionally, there are many other things that are checked and monitored to help detect, prevent, and maintain their dental health.  These include:

• Medical history review: Knowing the status of any current medical conditions, new medications, and illnesses, gives us insight to the overall health and also the dental health of your child.
• Examination of diagnostic dental digital images (radiographs): Essential for detection of decay, tumors, cysts, and bone loss.  These digital images also help determine tooth and root positions.
• Oral cancer screening: Check the face, neck, lips, tongue, throat, tissues, and gums for any signs of oral cancer.
• Gum disease evaluation: Check the gums and bone around the teeth for any signs of periodontal disease.
• Examination of tooth decay: All tooth surfaces will be checked for decay with special dental instruments.
• Examination of existing restorations: Check current fillings, crowns, etc.
• Removal of calculus (tartar): Calculus is hardened plaque that has been left on the tooth for sometime and is now firmly attached to the tooth surface.  Calculus forms above and below the gum line, and can only be removed with special dental instruments.
• Removal of plaque: Plaque is a sticky, almost invisible film that forms on the teeth.  It is a growing colony of living bacteria, food debris, and saliva.  The bacteria produce toxins (poisons) that inflame the gums.  This inflammation is the start of periodontal disease!
• Teeth polishing: Removes stain and plaque that is not otherwise removed during toothbrushing and scaling.
• Oral hygiene recommendations: Review and recommend oral hygiene aids as needed (electric dental toothbrushes, special cleaning aids, fluorides, rinses, etc.).
• Review dietary habits: Their eating habits play a particularly important role in their dental health.

As you can see, a good dental exam and cleaning involves much more than simply checking for cavities and polishing your teeth.  We are committed to providing you with the best possible care, and to do so, will require regular check-ups and cleanings.

Four out of five people have periodontal disease and don’t know it!  Most people are not aware of it because the disease is usually painless in the early stages.  Unlike tooth decay, which often causes discomfort, it is possible to have periodontal disease without noticeable symptoms.  Having regular dental check-ups and periodontal examinations are very important and will help detect if periodontal problems exist.

Periodontal disease begins when plaque, a sticky, colorless, film of bacteria, food debris, and saliva, is left on the teeth and gums.  The bacteria produce toxins (acids) that inflame the gums and slowly destroy the bone.  Brushing and flossing regularly and properly will ensure that plaque is not left behind to do its damage.

Other than poor oral hygiene, there are several other factors that may increase the risk of developing periodontal disease:

• Smoking or chewing tobacco – Tobacco users are more likely than non-users to form plaque and tartar on their teeth.

• Certain tooth or appliance conditions – Bridges that no longer fit properly, crowded teeth, or defective fillings that may trap plaque and bacteria.

• Many medications – Steroids, cancer therapy drugs, blood pressure meds, oral contraceptives.  Some medications have side affects that reduce saliva, making the mouth dry and plaque easier to adhere to the teeth and gums.

• Pregnancy, oral contraceptives, and puberty – Can cause changes in hormone levels, causing gum tissue to become more sensitive to bacteria toxins.

• Systemic diseases – Diabetes, blood cell disorders, HIV / AIDS, etc.

• Genetics may play role – Some patients may be predisposed to a more aggressive type of periodontitis.  Patients with a family history of tooth loss should pay particular attention to their gums.

Signs and Symptoms of Periodontal Disease

• Red and puffy gums – Gums should never be red or swollen.

• Bleeding gums – Gums should never bleed, even when you brush vigorously or use dental floss.

• Persistent bad breath – Caused by bacteria in the mouth.

• New spacing between teeth – Caused by bone loss.

• Loose teeth – Also caused by bone loss or weakened periodontal fibers (fibers that support the tooth to the bone).

• Pus around the teeth and gums – Sign that there is an infection present.

• Receding gums – Loss of gum around a tooth.

• Tenderness or Discomfort – Plaque, calculus, and bacteria irritate the gums and teeth.

Good oral hygiene, a balanced diet, and regular dental visits can help reduce your risk of developing periodontal disease.

Brushing our teeth removes food particles, plaque, and bacteria from all tooth surfaces, except in between the teeth.  Unfortunately, our toothbrush can’t reach these areas that are highly susceptible to decay and periodontal (gum) disease.

Daily flossing is the best way to clean between the teeth and under the gumline.  Flossing not only helps clean these spaces, it disrupts plaque colonies from building up, preventing damage to the gums, teeth, and bone.

Plaque is a sticky, almost invisible film that forms on the teeth.  It is a growing colony of living bacteria, food debris, and saliva.  The bacteria produce toxins (acids) that cause cavities and irritate and inflame the gums.  Also, when plaque is not removed above and below the gumline, it hardens and turns into calculus (tartar).  This will further irritate and inflame the gums and will also slowly destroy the bone. This is the beginning of periodontal disease.

How to floss properly:

• Take 12-16 inches (30-40cm) of dental floss and wrap it around your middle fingers, leaving about 2 inches (5cm) of floss between the hands.
• Using your thumbs and forefingers to guide the floss, gently insert the floss between teeth using a sawing motion.
• Curve the floss into a “C” shape around each tooth and under the gumline.  Gently move the floss up and down, cleaning the side of each tooth.

Floss holders are recommended if you have difficulty using conventional floss.

Daily flossing will help you keep a healthy, beautiful smile for life!

Although thorough brushing and flossing removes most food particles and bacteria from easy to reach tooth surfaces, they do not reach the deep grooves on chewing surfaces of teeth.  More than 75 percent of dental decay begins in these deep grooves (called pits and fissures). Toothbrush bristles are often too large to clean most of these areas, thus sealants play an important role.

A sealant is a thin plastic coating that covers and protects the chewing surfaces of molars, premolars, and any deep grooves or pits on teeth. Sealant material forms a protective, smooth barrier covering natural depressions and grooves in the teeth, making it much easier to clean and help keep these areas free of decay.

Who may need sealants?

Children and teenagers - As soon as the six-year molars (the first permanent back teeth) appear or any time throughout the cavity prone years of 6-16.

Children - Primary (baby) teeth are sealed if the teeth have deep grooves and the child is cavity prone.

Sealants are easily applied by your dentist or dental hygienist and the process only takes minutes per tooth. After the chewing surfaces are roughened with an conditioning gel that helps the sealant adhere to the tooth, the sealant material is “painted” onto the tooth surface, where it hardens and bonds to the teeth. A special light will be used to help the sealant material harden.

After sealant treatment, it’s important to avoid chewing on ice cubes, hard candy, popcorn kernels, or any hard or sticky foods. Your sealants will be checked for wear and chipping at your regular dental check-up.

Combined with good home care, a proper diet, and regular dental check-ups, sealants are very effective in helping prevent tooth decay.

Straighter teeth perform chewing, biting, and speaking functions more effectively than crooked teeth.   In addition, a straight smile boosts confidence, is aesthetically pleasing to look at, and can help stave off a wide variety of dental ailments.

There are several types of malocclusion including overbite, underbite, crossbite, and overcrowding.  Each of these alignment problems negatively impacts the functionality and cosmetic appearance of the teeth.

Here is a brief overview of some of the main disorders associated with crooked teeth:

Periodontitis – Periodontitis or gum disease begins with a bacterial infection.  The bacterial infection is caused by inadequate oral hygiene. Crooked teeth are hard to effectively clean, which means that debris, plaque, and bacteria can build up in hard-to-reach areas. Straight teeth are much easier to clean and are at less risk of contracting gum disease.

Temporomandibular Disorder (TMJ) - Crooked teeth can lead to improper jaw alignment, which in turn causes a painful condition known as TMJ. Severe headaches, jaw pain, lockjaw, and grinding of teeth characterize this debilitating disorder. 

Tooth injury – Straight teeth create a strong wall, which means injuries are less likely to occur.  Crooked teeth are weaker and often protrude, making them far more vulnerable to external injury.

Uneven wear – Crooked teeth cause some of the teeth to work harder than others when biting and chewing.  Straight teeth share the workload evenly, meaning less risk of injury and better aesthetics.

Teeth can be straightened using either orthodontic braces or customized aligning trays.  Orthodontic braces are usually affixed to the teeth for a set duration.  The brackets and archwires are tightened regularly by the orthodontist and removed when treatment is complete.  Fixed braces can be placed on the front side or back side of the teeth and are effective for most types of malocclusion.

Aligning trays are fully removable and are used where the malocclusion is less severe, and the teeth need to move a shorter distance.  These trays are replaced every few weeks for the duration of the treatment, and have proven to be equally effective for straightening teeth.
