Protect Your Teeth from Decay

Our mouths are home to many bacteria, most of which are harmless. Some bacteria, however, are responsible for causing cavities. Known as dental caries in the medical community, cavities are caused by acid-producing bacteria that destroy tooth enamel and dentin. According to Nashville dentist Warren Melamed, the most common locations for cavities to form include:

• Cracks, pits or grooves in the back teeth
• Between teeth
• Around dental fillings or bridgework
• Near the gum line

These sites are common cavity spots because they enable plaque to form easily. Plaque is a soft film that forms on teeth, sticking to them like jam sticks to a spoon. Plaque is a type of biofilm that is similar to the slime that forms in standing water. Just like other types of biofilm, plaque is not something you want to have a lot of in your mouth.

Plaque contains bits of food, saliva and closely-packed bacteria in large numbers. It starts to form right after a tooth is cleaned. Within an hour of cleaning, there is a measurable amount of plaque buildup. Plaque thickens as time passes. Within two to six hours, the plaque is full of bacteria that can cause cavities and gum disease.

If left long enough, plaque absorbs minerals from our saliva which then harden into calculus. Plaque continues to grow on top of these hardened spots, creating a new layer which may harden further. Plaque is easily removable with a toothbrush; calculus is not. This discrepancy is why it is so important to brush your teeth on a regular basis.

All of these processes contribute to the formation of cavities. Here’s how cavities form:

When a person eats sugary or starchy foods, the particles that remain in the mouth become food for bacteria.
These bacteria produce acids. The acids dissolve the mineral crystals in the teeth. The more times you eat in a day, the more your teeth are exposed to an acid attack. These attacks wear down enamel and create weak spots and even holes in teeth. White spots may appear on tooth enamel to signify a weak spot. At this stage, fluoride can still reverse the demineralization process.If bacteria have eaten away the tooth to form a cavity, the decay will need to be cleared and the hole filled by a dental professional.

One of the best tools at our disposal for preventing cavities occurs naturally in the mouth. Your mouth and teeth are constantly bathed in saliva, a natural liquid which keeps everything moist. Saliva washes away bits of food that would otherwise feed acid-producing bacteria. Saliva contains minerals that strengthen the teeth and buffering agents that reduce the acid levels in the mouth.

By reducing your saliva amounts, chronic dry mouth conditions can increase your risk for cavities. Other risk factors include:

• A history of cavities or tooth decay
• A lack of fluoride exposure through toothpaste, community drinking water or supplemental fluoride treatments
• Parents or siblings with high rates of dental decay
• Poor oral hygiene
• How often you consume particular foods, especially sugars and fermentable carbohydrates

While you can never completely remove bacteria from your mouth, you can control oral bacteria levels. Brushing daily, flossing and using mouthwash will reduce bacteria in your mouth and remove plaque. Dental pro Warren Melamed notes that visiting your dentist regularly can enable the identification of tooth decay before it necessitates to a filling or root canal.

Tips for Diagnosing and Treating Tooth Pain

Toothaches can be extraordinarily painful. Sometimes the pain is all you can think about. There are many causes of tooth pain, the most obvious of which is a problem with the tooth or jaw. The dental causes of tooth pain fall into three categories:

Damage: Trauma, including chips and breakage, can cause damage to teeth. This breakage can cause tooth pain.

Decay: Tooth decay has several degrees of severity. Cavities are holes that penetrate the enamel and the underlying dentin and cause pain. Abscesses are more severe. When an abscess occurs, the dental nerves and pulp become infected.

Disease: Redness and swelling of the gums indicate gum disease or gingivitis. Gum disease can cause gum and tooth pain. Other diseases, including oral cancer, may also contribute to tooth pain.

If you have tooth pain that persists for longer than one or two days, make a dentist appointment immediately. Unless it is an emergency, says dentist Warren Melamed, it is likely that you will have to wait a few days for your appointment.

If you have a toothache and cannot see a dentist right away, here are some things you can do to relieve pain while you wait:

• Avoid foods and beverages that are very cold or very hot. The decay or damage may have exposed the dentin layer of the tooth. Extreme temperatures may cause additional pain.
• Use over-the-counter pain relief medicine that is designed to reduce inflammation. Never put pain relief medication directly on the tooth or gum tissue as this application could damage these areas.
• Gently floss between the painful teeth. Removing the food particles and plaque may help to reduce the pain from the toothache.
• Use clove oil, or eugenol, for pain relief. Clove oil has both antiseptic and anesthetic properties. Soak a small piece of cotton in the oil anduse a pair of tweezers to hold the cotton on the tooth for 10 seconds. Make sure that you do not swallow any of the oil.
• Rinse with warm salt water.Salt water works as an antiseptic, removing bacteria from the infected or vulnerable area. Rinsing may provide additional pain relief.

There are some causes of tooth pain that are not directly related to your dental health. If none of the three general categories of pain are causing the problem, consider the following conditions:

• Sinus Infection: Sinuses that are infected can become swollen, putting pressure on certain teeth.
• Cluster Headache: Cluster headaches cause pressure that may contribute to tooth pain. Their exact cause remains unknown.
• Heart Attack: Pain from a heart attack may radiate into the lower jaw.
• Diabetes: Uncontrolled blood sugar can increase your risk of tooth decay. Frequent cavities may be an indication of a more serious problem.
• Viral Infections: Viral infections such as shingles can cause tooth pain.
• Nerve Diseases: Trigeminal neuralgia is an example of a nerve disease that is associated with sharp pain on one side of the face. 

Toothaches are preventable in most cases, especially when the pain is caused by decay. Follow good oral hygiene practices, making sure to brush and floss twice a day. Sealants and fluoride applications can also defend your teeth from bacteria. Consult with your dentist for more information on how to protect your teeth.

Dental Health for Pregnant Women

Many things go through a woman’s mind when she finds out that she is pregnant. When will she have her first ultrasound? What will she name the baby? Is it a boy or a girl?

Her dental health may well be one of the last things on her mind. However, a mother’s oral health can affect the health of her baby.

Mothers with gum disease have a higher instance of preterm birth. Preterm birth can cause serious problems for the infant, including low birth weight. Hormonal changes during pregnancy may also render a mother more susceptible to teeth and gum problems.

Preventing Pregnancy Gingivitis

In 2009, the American Academy of Pediatric Dentistry announced new oral health guidelines for pregnant women. These guidelines are designed to help pregnant women maintain healthy teeth and gums during their pregnancy and throughout the early stages of motherhood. These guidelines include:

1. Oral Hygiene: Correct brushing and flossing practices can help remove bacterial plaque, which is connected to preterm birth.
2. Fluoride: Pregnant women should continue to use fluoridated toothpaste. They should also use an over-the-counter alcohol-free fluoride rinse to reduce the amount of plaque in their mouths.
3. Treatment of Existing Tooth Decay: Existing tooth decay should be treated during pregnancy. Restoring decayed teeth will improve oral health by removing bacteria produced by the decay process.
4. Prevention of Transmission of Bacteria: Expectant mothers are discouraged from sharing utensils or food with others. Avoid sharing these items in order to prevent the transmission of bacteria that cause tooth decay.
5. Use of Xylitol Gum: When chewed four times a day, gum sweetened with xylitol has been shown to decrease the rate of tooth decay in children.

Pregnancy gingivitis develops in almost half of all pregnant women. It typically ends shortly after the birth, but it should be monitored throughout the pregnancy to ensure that it doesn’t progress into periodontitis. A more serious form of gum disease, periodontitis is irreversible. Pregnant mothers with periodontal disease are seven times more likely to go into preterm labor.

The Dangers of Preterm Birth

It may be hard for a pregnant mom to internalize the true danger that periodontitis poses for an unborn baby. The danger lies in prostaglandin, a chemical found in oral bacteria. High levels of prostaglandin have been found in the mouths of women with periodontitis. Prostaglandin may work to induce labor in pregnant women, causing preterm birth.

Babies born too early often have a low birth weight, which can cause significant health problems. Babies born prematurely have an increased risk of developing lung conditions, heart conditions and learning disorders. If you are pregnant or may become pregnant, consult your dentist about the state of your oral health.

FAQs about Bad Breath

What should I do if I have bad breath?

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 reasons one may have bad breath, but in healthy people, the major reason is due to microbial deposits on the tongue, especially the back of the tongue. Some studies have shown that simply brushing the tongue reduced bad breath by as much as 70 percent.

What may cause bad breath?

• Morning time – Saliva flow almost stops during sleep and its reduced cleansing action allows bacteria to grow, causing 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 you 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, but bad breath is persistent, your dentist may refer you to your physician to determine the cause of the odor and an appropriate treatment plan.
