Keeping Tooth Decay Under Control

Tooth decay is the most prevalent chronic disease in adults and children worldwide, second only to the common cold. It’s a silent epidemic that can lead to pain, tooth loss, and other conditions that negatively impact your overall health and well-being. That may sound dire, but tooth decay is also largely preventable. With a consistent and proactive approach to oral hygiene, you can take control of your dental health and keep cavities at bay. 

What Exactly is Tooth Decay?

To combat tooth decay, also known as dental caries, it’s necessary to understand what it is and how it develops. Our mouths are an ecosystem of bacteria, both good and bad. Harmful bacteria, most notably Streptococcus mutans, thrive on the sugars and starches we consume.

When we eat or drink sugary or starchy foods, these bacteria join the feast. As they metabolize sugars, they produce acids as a byproduct. These acids are the real problems, attacking the hard, protective outer layer of our teeth – the enamel. This process is called demineralization.

Fortunately, our bodies have a natural defense mechanism: saliva. Our saliva is not just for keeping our mouths moist; it’s rich in minerals like calcium and phosphate, which help to neutralize these acids and replenish the minerals lost from the enamel. This counter-process is called remineralization.

Tooth decay occurs when the rate of demineralization outpaces the rate of remineralization. Over time, the constant acid attacks create weak spots in the enamel. If left unchecked, these weak spots will eventually break down, forming a cavity. If the decay progresses further, it can penetrate the softer, inner layer of the tooth – the dentin – and eventually reach the pulp, which contains the nerves and blood vessels. This is when people experience significant pain and when infections form, potentially leading to the need for a root canal or even tooth extraction.

The Cornerstone of Control: Impeccable Oral Hygiene

Your daily oral hygiene routine is the first and most important line of defense against tooth decay. It’s not just about brushing your teeth; it’s about doing it correctly and consistently.

• Frequency: The American Dental Association (ADA) recommends brushing your teeth twice a day for two minutes each time. Brushing in the morning helps to remove the plaque that has accumulated overnight, and brushing before bed is crucial to clean away the food particles and sugars from the day’s meals, preventing them from wreaking havoc while you sleep.
• Technique: Use a soft-bristled toothbrush. Hard bristles can be abrasive and damage your enamel and gums. Angle the brush at a 45-degree angle to your gum line and use gentle, circular motions. Make sure to brush all surfaces of your teeth: the outer, inner, and chewing surfaces.
• Don’t Forget Your Tongue: Bacteria can also accumulate on your tongue, leading to bad breath and contributing to the overall bacterial load in your mouth. Gently brush your tongue or use a tongue scraper as part of your daily routine.
• The Power of Fluoride: Despite what some folks in the government are saying, fluoride is your friend. Always use a toothpaste that contains fluoride. Fluoride is a naturally occurring mineral that fights against tooth decay. It works in two ways: it helps to remineralize weakened enamel, making it more resistant to acid attacks, and it can also inhibit the ability of plaque bacteria to produce acid.
• Timing is Everything: Ideally, you should wait about 30 to 60 minutes after a meal to brush your teeth, especially if you’ve consumed acidic foods or drinks. Brushing immediately after can spread the acid around and cause more damage to your temporarily softened enamel.

Skipping Flossing Is an Invitation for Tooth Decay

Brushing alone can’t reach the tight spaces between your teeth and under the gumline. This is where flossing comes in. Flossing once a day is essential to remove plaque and food particles from these hard-to-reach areas, preventing the formation of cavities between your teeth.

Take about 18 inches of floss and wrap most of it around one middle finger, and the rest around the other. Hold the floss tightly between your thumbs and forefingers. Gently guide the floss between your teeth using a rubbing motion. When the floss reaches the gum line, curve it into a C-shape against one tooth. Gently slide it into the space between the gum and the tooth. Hold the floss tightly against the tooth and gently rub the side of the tooth, moving the floss away from the gum with up-and-down motions. Repeat this process for all of your teeth, including the back of your last molars.

Mouthwash: An Extra Layer of Protection

An antimicrobial or fluoride mouthwash can be a beneficial addition to your oral hygiene routine, but it should not be a substitute for brushing and flossing. A therapeutic mouthwash can help to reduce the amount of bacteria in your mouth, inhibit plaque formation, and provide an extra dose of fluoride. Look for a mouthwash that has the American Dental Association (ADA) Seal of Acceptance.

Diet Plays a Role in Tooth Decay

What you eat plays a direct role in your risk of developing tooth decay. Every time you consume sugary or starchy foods, you’re essentially feeding the cavity-causing bacteria in your mouth.

Sugar

The more frequently you expose your teeth to sugar, the more acid is produced and the longer your teeth are under attack. It’s not just about the amount of sugar you consume, but also the frequency. Sipping on a sugary drink over a long period is more damaging than drinking it all at once with a meal. You should try to avoid the following foods and beverages.

• Sugary Drinks: Sodas, fruit juices, sports drinks, and sweetened teas and coffees are major culprits.
• Sticky Candies and Sweets: Caramels, gummies, and hard candies linger in the mouth, providing a prolonged sugar source for bacteria.
• Starchy Foods: Chips, crackers, and white bread can get trapped between your teeth and break down into simple sugars.
• Dried Fruits: While they may seem healthy, dried fruits are often sticky and high in sugar.

On the other hand, these foods and drinks go a long way on the road to preventing tooth decay.

• Fiber-Rich Fruits and Vegetables: Foods like apples, carrots, and celery have a natural cleansing action that can help to scrub your teeth and stimulate saliva flow.
• Dairy Products: Cheese, milk, and plain yogurt are rich in calcium and phosphorus, the building blocks of strong enamel. They can also help to raise the pH level in your mouth, making it less acidic.
• Lean Proteins: Poultry, fish, meat, and nuts contain phosphorus that helps to protect tooth enamel.
• Water: Water, especially fluoridated water, is the best beverage for your teeth. It helps to wash away food particles and sugar, and it keeps you hydrated, which is essential for saliva production.

Harnessing the Power of Fluoride

Fluoride is so effective at preventing tooth decay that the Centers for Disease Control and Prevention (CDC) has named community water fluoridation as one of the 10 great public health achievements of the 20th century.

• Fluoridated Water: Drinking fluoridated tap water is one of the easiest and most effective ways to protect your teeth.
• Topical Fluoride: In addition to fluoride toothpaste and mouthwash, your dentist can apply a professional fluoride treatment in the form of a gel, foam, or varnish. These treatments contain a higher concentration of fluoride and provide a significant boost to your teeth’s defenses.

Professional Dental Care: Your Partners in Tooth Decay Prevention

Regular visits to your dentist and dental hygienist are not just for when you have a problem; they are a cornerstone of preventive care. And with Dentists on Demand, we bring dentists and hygienists right to your office.

• Professional Cleanings: Even with the most diligent brushing and flossing, some plaque can harden into tartar (calculus), which can only be removed with professional instruments. A professional cleaning at least twice a year is essential to remove tartar buildup and keep your teeth and gums healthy.
• Dental Examinations: During a check-up, your dentist can identify the early signs of tooth decay, often before you experience any symptoms. Early detection allows for more conservative and less invasive treatment options.
• Dental Sealants: For children and even some adults, dental sealants can be a highly effective preventive measure. A sealant is a thin, plastic coating that is painted onto the chewing surfaces of the back teeth (molars and premolars). These surfaces have deep grooves and pits that can be difficult to clean and are prime locations for decay. The sealant acts as a protective barrier, “sealing out” food and plaque.
• Personalized Advice: Your dental team can provide you with personalized advice on your oral hygiene routine, diet, and any specific risk factors you may have.

Addressing Specific Challenges

Managing Dry Mouth (Xerostomia)

Saliva is your body’s natural defense against tooth decay. If you suffer from dry mouth, your risk of cavities is significantly increased. Dry mouth can be caused by certain medications, medical conditions, or lifestyle factors.

• Stay Hydrated: Sip water throughout the day.
• Sugar-Free Gum or Sugar-Free Candy: These items can help stimulate saliva flow. Look for products containing xylitol.
• Use a Humidifier: Running a humidifier at night can help to add moisture to the air.
• Avoid Alcohol, Caffeine, and Tobacco: These can all contribute to dry mouth.
• Talk to Your Dentist or Doctor: They can recommend artificial saliva substitutes or other treatments.

The Power of Xylitol

Xylitol is a natural sugar substitute that has been shown to have anti-cavity properties. Unlike regular sugar, the bacteria in our mouths cannot metabolize xylitol to produce acid. In fact, xylitol can even inhibit the growth of Streptococcus mutans. Chewing xylitol-sweetened gum or using xylitol-containing products can be a helpful addition to your preventive routine.
