How Does Sensitive Toothpaste Work?

sensitive toothpasteSensitive teeth are a bothersome and painful problem which causes pain in the teeth when they are exposed to certain conditions. Exposure to hot and cold, even pressure can cause tooth pain for people with sensitive teeth, causing them to avoid certain foods and even activities in order to prevent it.

What Causes Sensitive Teeth?

The cause of sensitive teeth lies in the anatomy of a tooth. Your tooth is made up of two main parts- the crown (above the gum) and the root (below the gum). A hard covering called enamel protects the exposed portion of the tooth from decay and sensitivity.

Beneath the enamel, the tooth is made up of dentin and pulp. The pulp is the vital, part of the tooth structure which contains the blood supply and the nerve. Extending from the outside of the tooth into the nerve canal are tiny, microscopic tubules or pores.

When sensitive teeth are exposed to heat, cold and pressure, the sensation of pain occurs as a result of the nerve detecting the stimulant through the tubules. People with sensitive teeth often have a thinning of the tooth enamel, reducing its protection against feeling pain. Gum recession with resultant exposed tooth root is also a common cause.

Sensitive Toothpaste Can Help

Sensitive toothpaste works by one of two means. In some sensitive toothpaste, an ingredient called potassium nitrate causes a mild numbing of the nerve, blocking the sensation and helping ease sensitivity. Other sensitive toothpastes work by blocking the tubules which lead to the nerve inside the tooth. An ingredient called potassium nitrate builds up inside the tubules, and over time works to block them, preventing the sensation of hot and cold from reaching the nerve.

Do You Have Sensitive Teeth?

Sensitive teeth can be a real pain. Your first step to solving the problem is to have a dental check-up with Dr. Ban.  A dental exam will help make sure that your sensitive teeth are not caused by another problem such as tooth decay, gum disease or injury. Dr. Ban can recommend a sensitive toothpaste and other treatments which may be available to you in order to treat your sensitive teeth.

Are Sodas Destroying Your Teeth?

We all know a healthy diet is important to maintaining overall health and well-being, but when it comes to your dental health, your diet plays an important role as well.

Avoiding sugary snacks and making sure to brush and floss every day is a good place to start, but what about the things you drink?  Many people are not aware that sodas and fruit juices are a leading cause of tooth decay in adults.

Sodas Are An Acid Bath To Your Teeth

Let’s take closer look at sodas to understand exactly how they can damage your teeth and lead to cavities.

Sodas, even diet sodas are extremely acidic.  Acids in foods and drinks cause damage to your tooth enamel- the hard protective exterior of the tooth structure.  When you drink an acidic soda, fruit juice, flavored water or even sports drinks, the acid bathes your tooth surfaces.  Normally, your saliva will wash away the acids and restore normal psoda factsH in the mouth, but when acidic drinks are consumed too frequently, or sipped on all day, there is no time between acid baths for your body to correct the pH.  Frequent exposure to acids wears on your tooth enamel, causing acid erosion.  Early symptoms may be excess sensitivity to cold or hot food.  As enamel erosion progresses, sensitivity increases as more of the dentin (interior of the tooth) is exposed.  As enamel softens and becomes more porous, pain can increase.

Porous and Softened Enamel Is Susceptible To Tooth Decay

When tooth enamel breaks down, it leaves the tooth susceptible to tooth decay.  As enamel breaks down, teeth lose mineral content.  Enamel erosion can change the surface of the tooth, leaving tiny weak areas for cavity-causing bacteria to take hold.  Simply avoiding sugar is not enough to prevent this damage from occurring.  Drinking water or milk are your best defenses against enamel erosion.

A study in the Journal of Public Health Dentistry concluded that nearly 79% of study participants showed signs of dental erosion.  The most common cause was frequent consumption of sodas and fruit juices.

Avoid Sodas For Dental Health

Avoiding sodas, fruit juices and flavored waters or sports drinks is good advice.  If you cannot kick the habit completely, then watch how you consume these beverages.  Drink a soda or sports drink at once, rather than sip on it slowly.  This will allow your body to correct the pH imbalance that occurs with acidic drinks.  Follow up your acidic beverage with water.  Some studies conclude that brushing immediately after an acidic drink is not a good idea, because enamel softened by the acid can be worn away by brushing.  Instead, rinse well with water and brush later.

Help For Sensitive Teeth

Sensitive teeth can be caused by acid erosion.  See your Saratoga dentist for an examination if you have painful, sensitive teeth.  Treatments including fluoride application and preparations that can restore mineral content are available from your dentist.
