What is Tooth Sensitivity?

What is Tooth Sensitivity?
Tooth sensitivity is a common name for dentin hypersensitivity or root sensitivity. If hot, cold, sweet or very acidic foods and drinks, or breathing in cold air, makes your teeth or a tooth sensitive or painful then you have sensitive teeth.

Is Tooth Sensitivity Common? 
Tooth sensitivity is very common and it has been estimated that approximately half the population experiences tooth sensitivity. Tooth sensitivity can come and go over time.

Why does Tooth Sensitivity (Dentin Hypersensitivity) Happen? 
Tooth sensitivity is usually caused by dentin on root areas exposed due to receded gums or periodontal disease. Receded gums are very common and up to four fifths of people have gum recession by the time they are 65.  

When the root of a tooth becomes exposed it does not have a layer of enamel like the crowns of your teeth. Instead the roots have a very soft covering called cementum, which once lost leaves the dentin of the root exposed.  Overzealous brushing or using a very abrasive toothpaste can also cause abrasion of the tooth's enamel surface and expose dentin. A very acidic diet - for example a diet with a lot of citrus food, pickles or sodapop - can cause tooth erosion and dissolve the tooth surface, exposing the dentin. Bulimia and GERD can also result in dental erosion and sensitivity due to acid in the mouth.

Treatment Options for Tooth Sensitivity

The best way to find out why a tooth is sensitive is to have dental professional examine you. They can look for the signs of dentin exposure, and run tests to determine what the true cause of the sensitivity is. Sometimes, the sensitivity is due to a cavity or gum disease - these can be treated to address the sensitivity. Other times, the cause of the sensitivity is because the enamel has been lost through abrasion or erosion, or the gums have receded, causing the roots to be exposed.

What Can Be Done?
If the sensitivity is due to a cavity, a restoration can be placed. If gum disease is the cause, the dental professional can perform a thorough cleaning of the area.

However, if the cause is from dentin being exposed, then there are a number of professional and at home treatments that can be used to reduce the sensitivity.

In Office Procedures:

• Fluoride varnish can be applied to exposed areas, strengthening the enamel and dentin
• Fluoride foam or gel can be placed into a mouth tray; you then sit with this in your mouth for 3-5 minutes, providing the teeth with a high concentration of fluoride to strengthen the areas
• Bonding agent, the material used to stick tooth colored restorations to teeth, can be used to seal the dentin surface and provide a barrier to the stimuli that cause sensitivity

At Home:

• Use a very soft bristle tooth brush, with low abrasive tooth paste
• Brush correctly and do not over brush
• Use a tooth paste specially formulated to soothe the nerve endings in the tooth
• Use a high concentration fluoride toothpaste (given to you by the dental professional) to strengthen the tooth surface

There are a number of treatments available, and your dental professional can help you find those that will work best, depending on your situation. Always seek a dental professional's help - do not try to diagnose this problem yourself. It may be the sign of something more serious, and only a dental professional can tell you what it really is.

Good Food for Dental Health: Water

Water Rules
Water, especially fluoridated water, is the best beverage for maintaining your oral health. That's because fluoride helps to make teeth more resistant to the acid attacks that can cause cavities. As of 2012, nearly 75 percent of the U.S. population had access to fluoridated water, so drinking water from your own kitchen sink can help prevent dental problems.

Tooth Cavities

Tooth cavities aren't uncommon - but with the right dental health know-how, you can help prevent them. It all starts with proper brushing, daily flossing, and fluoride. Get the details right here.

What Causes Tooth Cavities?
Cavities are holes in the teeth resulting from acid attack. They generally start in the enamel, but can spread to the softer inner layer of the tooth. Tooth cavities are caused by decay that can occur when foods containing carbohydrates become trapped between teeth, and are not completely removed with brushing and flossing. Bacteria living in the mouth digest these foods, generating acidic byproducts that can eat away at tooth enamel.

Help Prevent Tooth Cavities
Fluoride, which is found in most public drinking supplies, some mouth rinses, and Crest toothpastes, helps prevent tooth cavities by slowing the breakdown of enamel and speeding up the remineralization process. Check with your dental professional to see if your drinking water is fluoridated. If it isn't, he or she may recommend that you use high concentration fluoride treatments.

To help strengthen weak spots in tooth enamel, and help prevent the early stages of tooth decay, brush regularly with a fluoridated toothpaste, floss daily, and visit your dental office regularly for professional cleanings.

How to Fight Mouth Germs and Keep Your Smile Healthy

Below is an excerpt from an article found on Colgate.com that was written by Brenna Stone

Does the thought of mouth germs taking up residence on your teeth make you feel a little uncomfortable? It should! Masses of harmful microorganisms in the mouth can form plaque, the sticky substance that adheres to the teeth and gumline. Plaque can really harm your teeth and gums. When it isn't removed by regular brushing and flossing, it can lead to cavities and gum disease! Find out what you can do to reduce the amount of germs in your mouth.

Regular Toothbrushing
Toothbrushing is a powerful tool for fighting germs. At the minimum, brush twice a day with a fluoride toothpaste; once after breakfast and once before going to bed. There is no harm in brushing your teeth more frequently. You can brush after meals to cut down on plaque formation and to freshen your breath. Spend a full two minutes gently brushing all surfaces of your teeth and your tongue. Use a toothpaste like Colgate Total that is designed to keep your mouth clean and to fight germs.

Bacteria can flourish on your toothbrush as well. Change your toothbrush when it begins to look worn, according to American Dental Association. The American Dental Association recommends switching to a new brush about every three to four months. It is best to leave your bristles in the open air; a closed, moist environment can harbor more bacteria. Also, don't share brushes; it is possible to transfer mouth germs this way.

Don't Forget to Floss
Daily flossing is another important way to keep your mouth clean and healthy. Flossing can help to remove plaque from places that your toothbrush can't reach. Slide your floss in between the teeth. Also clean at the base of each tooth, removing plaque and food debris from underneath the gum line.

Your Diet and Mouth Germs
What you eat can also help to support a healthy smile. Eating lots of sugary and starchy foods will increase the amount of sugars that are available for bacteria in your mouth to thrive upon. Try cutting back on sweet treats and snacking on fresh fruits and veggies instead. When eating grains, be sure to choose whole grains.

Take good care of your teeth with daily brushing and flossing. Eat a balanced diet and see your dentist for regular check-ups. Your dentist can check for signs of cavities and gum disease, the dental hygienist can also clean your teeth, removing the plaque and tartar (hardened dental plaque) that is on your teeth. With excellent oral hygiene, mouth germs don't stand a chance!

What is Plaque?

Plaque is a sticky, colorless deposit of bacteria that is constantly forming on the tooth surface. Saliva, food and fluids combine to produce these deposits that collect where the teeth and gums meet. Plaque buildup is the primary factor in periodontal (gum) disease, including gingivitis.

How to Get Rid of Plaque

To help prevent plaque buildup, be sure to brush your teeth at least twice a day with an anti-plaque toothpaste such as Crest Pro-Health Toothpaste for around the clock protection against plaque buildup, and floss once a day.

Adding a mouth rinse such as Crest Pro-Health Multi-Protection Rinse to your routine can help against plaque buildup, without the burning sensation of alcohol. Eating well-balanced meals and brushing after snacks will reduce the formation of plaque. Visit your dental office regularly for oral exams and cleanings, during which your dental professional will scrape away any accumulated plaque with a special instrument.

Sports Safety: Avoiding Tooth and Mouth Injuries

A few years ago, a dental newsletter published what seemed like an unusual story. A boy snagged his teeth on a basketball net while doing a slam-dunk.
A freakish accident? Not quite. After the article appeared, nearly 40 dentists wrote in with their own stories. They all told of would-be Michael Jordans who sacrificed their front teeth in pursuit of the perfect dunk.
In older children and adults, sports injuries are common. Dentists estimate that between 13% and 39% of dental injuries occur while playing sports.
About 80% of all dental injuries affect at least one of the front teeth. Damage to the tongue or cheek is common, too.
Basic Protection
Even if a tooth has been knocked out, it often can be saved if you get to a dentist quickly enough. Minor chips and cracks can be repaired. Dentists use tooth-colored materials that are nearly as strong as the original tooth. However, even "minor" injuries can cause serious and costly damage. If you enjoy sports or other high-risk activities, protect yourself. The use of mouth guards among football players, for example, is believed to prevent about 200,000 mouth injuries a year.
Depending on the sport, two types of protection are available:

• Helmets- A helmet is a must for activities that involve speed or impact. These include football, hockey, skating and bike riding. The helmet should fit correctly. It should also be appropriate for the sport you are playing.
• Mouth guards - Wearing a mouth guard is one of the best ways to prevent injury to your teeth, tongue and lips. A custom-fit mouth guard from your dentist is recommended. This type of mouth guard usually fits better than a ready-made one (found in sporting-goods stores). That means it may protect your teeth better.

If a custom-fit mouth guard isn't an option, try a "boil-and-bite" mouth guard. You can buy one in a sporting-goods store. You place the mouth guard in boiling water. Once the plastic is soft (but not too hot), you bite down on the mouth guard and mold the softened plastic around your teeth. If the mouth guard doesn't fit comfortably the first time, you can reheat it and do it again.

Tooth Anatomy

What Are the Different Parts of a Tooth?

• Crown- the top part of the tooth, and the only part you can normally see. The shape of the crown determines the tooth's function. For example, front teeth are sharp and chisel-shaped for cutting, while molars have flat surfaces for grinding.
• Gumline- where the tooth and the gums meet. Without proper brushing and flossing, plaque and tartar can build up at the gumline, leading to gingivitis and gum disease.
• Root- the part of the tooth that is embedded in bone. The root makes up about two-thirds of the tooth and holds the tooth in place.
• Enamel- the outermost layer of the tooth. Enamel is the hardest, most mineralized tissue in the body - yet it can be damaged by decay if teeth are not cared for properly.
• Dentin- the layer of the tooth under the enamel. If decay is able to progress its way through the enamel, it next attacks the dentin - where millions of tiny tubes lead directly to the dental pulp.
• Pulp- the soft tissue found in the center of all teeth, where the nerve tissue and blood vessels are. If tooth decay reaches the pulp, you usually feel pain.

What Are the Different Types of Teeth?
Every tooth has a specific job or function (use the dental arch in this section to locate and identify each type of tooth):

• Incisors- the sharp, chisel-shaped front teeth (four upper, four lower) used for cutting food.
• Canines- sometimes called cuspids, these teeth are shaped like points (cusps) and are used for tearing food.
• Premolars- these teeth have two pointed cusps on their biting surface and are sometimes referred to as bicuspids. The premolars are for crushing and tearing.
• Molars- used for grinding, these teeth have several cusps on the biting surface

How to Brush Your Teeth Properly: A Quick Guide

Below is an excerpt from an article found on Colgate.com that was written by AM Hopkins

Everyone knows that brushing their teeth plays a major role in their overall health, but they may not be aware of the correct way to brush their teeth. The American Dental Association recommends that you brush your teeth at least twice each day; here is a quick guide to ensure you know how to do it properly.

Purchase the right toothbrush. Before you even begin the process of brushing your teeth, it's important that you have the right toothbrush. The type of toothbrush you select depends on your specific needs. If you need a toothbrush mostly for removing plaque, a soft-bristled brush is best. On the other hand, if you are concerned about reaching hard-to-reach spaces, you should consider a toothbrush with a smaller head. in the Colgate Oral Care resources.

Take your time. You should spend at least two minutes brushing your teeth. This may seem like a long time - the average person usually falls short of this goal - but it is necessary ensure that your teeth are clean. If you're worried about reaching this goal, consider investing in a toothbrush that has an automatic timer or use a stopwatch.

Be thorough. Tilt your toothbrush to a 45 degree angle and ensure that you are cleaning both the outer and inner surfaces of your upper and lower teeth. It is equally important to clean the chewing surfaces of your teeth, as well.

Be gentle. When brushing your teeth, it's important to use short, precise strokes. This ensures that you don't cause any trauma to your mouth and that you reach the specific areas you are trying to target. You should brush the entire surface of the tooth in a gentle back and forth motion.

Don't forget your tongue. Brushing your tongue is an essential part of maintaining proper oral care. Many people often overlook this step, but it is important to both your overall oral hygiene and the freshness of your breath.

Good Food for Dental Health: Fruits & Veggies

Fruits and Veggies Pack an Extra Punch
Fruits and veggies are an important part of any balanced diet, and they are also good for your teeth. Since they are high in water and fiber, they help to balance the sugars they contain and help to clean your teeth. Chewing also helps to stimulate saliva production, which washes harmful acids and food particles away from your teeth.

Tooth Decay and Sensitivity

What Causes Tooth Enamel Damage?

What happens when tooth enamel is damaged? The exposed part underneath becomes vulnerable to decay. Cavities aren't the only problem.

Teeth with damaged enamel can become sensitive to extreme temperatures. Suddenly, eating ice cream or sipping hot coffee can be painful or unpleasant.
