The medical term for dry mouth is xerostomia (“xero” – dry; “stomia” – mouth), something that many of us have experienced at some point in life. However, for some people it can be a chronic condition that is ideal for promoting tooth decay. It can also be a warning sign of a more serious health condition.

Dry mouth occurs when there is an insufficient flow of saliva, the fluid secreted by the salivary glands. Your major salivary glands are located in two places: inside the checks by the back top molars and in the floor of the mouth, with about six hundred tiny glands scattered throughout your mouth. And many people are surprised to learn that when they are functioning normally, saliva glands secret between two and four pints of saliva per day! While this may sound like a lot (and it is), saliva is key for buffering or neutralizing acids in the mouth. Without this powerful protection, tooth decay can increase quickly. This is especially true for older individuals who have exposed tooth root surfaces.

It is also important to note that there are times when mouth dryness is perfectly normal. For example, when you wake, you will probably have a slightly dry mouth because saliva flow slows at night. Another example is if you are dehydrated when it is simply a warning sign that you need to drink more fluids (especially water). Other causes for temporary dry mouth include stress as well as what you consume: coffee, alcohol, onions, and certain spices.

You can also have a dry mouth due to a side effect from an over-the-counter (OTC) or prescription medication. If it turns out that this is the cause in your case, you need to talk to the prescribing physician to see if there is something else you can take to avoid this side effect. If there are no substitutes, one tip you can try is to take several sips of water before taking the medication followed by a full glass of water, or chew gum containing xylitol, which moistens your mouth and decreases the risk of tooth decay.

Another cause of dry mouth is radiation treatment for cancer in the head and neck region. Yes, these treatments are crucial for fighting cancer; however, they can inflame, damage or destroy salivary glands. You can also have dry mouth from certain systemic (general body) or autoimmune (“auto” – self; “immune” – resistance system) diseases, diabetes, Parkinson's disease, cystic fibrosis and AIDS (Acquired Immune Deficiency Syndrome).

Did you know that recent research has shown diabetes is a risk factor for increased severity of periodontal (gum) disease and that periodontitis is a risk factor for worsening blood glucose (sugar) control in people with diabetes? Periodontitis can even increase the risk of diabetic complications for people diagnosed with diabetes. When you combine these facts with the following, you will clearly see how important it is to understand and manage these two diseases.

• Over 23 million people in the United States currently have diabetes and over 170 million worldwide.
• 14+ million Americans have a condition called pre-diabetes.
• Another estimated 6 million people in the US have diabetes but are unaware and thus not diagnosed.
• Periodontal disease is the second most common disease known to man, only surpassed by tooth decay.
• Diabetic individuals with periodontal disease have a greater risk for cardiovascular and kidney complications than those diabetics not having periodontal disease.

What You Can Do

One of the most important steps you can take if you have either of these conditions or suspect that you might have one or both is to make an appointment with your physician or with our office for a thorough examination. You should schedule an appointment with your physician for an exam and blood work so that your general health and well-being are monitored. Be certain to share your medical information and any family history of diabetes with our office, as it tends to occur in families.

When dentists talk to patients, they often use specialized vocabulary referring to various dental conditions. Do you understand what they mean when they use these words — or are you wondering what they are talking about?

Here's your chance to test your knowledge of ten words that have a particular meaning in the context of dentistry. If you already know them, congratulations! If you don't, here's your chance to learn what these words mean in the dental world.

Enamel
In dentistry, enamel is the hard outer coating of your teeth. It is the hardest substance produced by living animals. It is a non-living, mineralized, and composed of a crystalline form of calcium and phosphate.

Dentin
The dentin is the layer of a tooth that is just beneath the enamel. It is living tissue similar to bone tissue.

Pulp
When dentists speak of pulp, we mean the tissues in the central chamber of a tooth (the root canal) that nourish the dentin layer and contain the nerves of the tooth.

Bruxism
Many people exert excess pressure on their teeth by clenching or grinding them. This is called bruxism, a habit that can be very damaging to teeth.

Occlusion
By this we mean how the upper and lower teeth are aligned, and how they fit together. This can also be referred to as your bite.

Dental caries
This term refers to tooth decay. Dental caries and periodontal disease (see below) are two of the most common diseases known to man. Today, these diseases are not only treatable, but they are also largely preventable.

Periodontal disease
A term for gum disease, this term comes from “peri,” meaning around and “odont,” meaning tooth. It is used to describe a process of inflammation and infection leading to the progressive loss of attachment between the fibers that connect the bone and gum tissues to the teeth. This can lead to loss of teeth and of the bone itself.

Erosion
When you consume acidic foods or drinks, the acids in your mouth react directly with minerals in the outer enamel of your teeth, causing chemical erosion. This is not the same as tooth decay, which is caused by acids released by bacterial film that forms on your teeth (see below).

Dental implant
A dental implant is a permanent replacement for a missing tooth. It replaces the root portion of the tooth and is most often composed of a titanium alloy. The titanium root fuses with the jaw bone, making the implant very stable. A crown is attached to the implant and can be crafted to match your natural teeth.

Plaque
Dental plaque is the whitish film of bacteria (a biofilm) that collects on your teeth. Your goal in daily brushing and flossing is to remove plaque.

If you have ever suffered from tooth sensitivity, you know all too well how real the pain can be — anything from a slight twinge to pain that can be downright excruciating. Sensitivity may be experienced several times throughout the day or just every once in a while. However, as we say, a little knowledge can go a long way. And we can provide you with the know-how and steps to help minimize your tooth sensitivity.

One of the first steps we will take is to review your brushing habits, as an improper brushing technique can not only cause tooth sensitivity, but it also can make the sensitivity worse once it is present. We will teach you how to remove dental plaque safely without damaging your delicate gum tissues, which can cause gum recession leaving the dentin exposed. Another step we may take is to provide you with a special toothpaste containing fluoride or one specifically targeted to sensitive teeth. The fluoride increases the strength of tooth surfaces and thus makes teeth more resistant to acid attack and sensitive to sweets. Or if the sensitivity is severe and/or constant, we may need to apply a barrier to cover the sensitive areas. These barriers may range from concentrated fluoride varnishes to bonded filling materials to cover the sensitive areas. If the pain is severe and constant, it may be possible that the pulpal tissue containing the nerves in your tooth are inflamed and you may need a root canal treatment to relieve your pain and save the tooth.

If you are experiencing tooth sensitivity or have questions about this condition, please contact us to schedule an appointment. Or you can learn more about this topic by reading the article “Sensitive Teeth.”

Oral cancer is on the rise in the United States, yet few people are familiar with the disease and its risk factors. The National Institute of Dental and Craniofacial Research (NIDCR) estimates that 35,000 Americans are diagnosed with the disease each year. The good news is that prevention and early detection can greatly reduce your risk of developing oral cancer.

Risk Factors for Oral Cancer Include:

• Tobacco: Smoking and using chewing tobacco have been shown to increase the risk of developing oral cancer.
• HPV virus: The Human Papilloma Virus (HPV) is the same virus linked to cervical cancer and genital warts. According to the Oral Cancer Foundation (OCF), many young people and women are being diagnosed with oral cancer as a result of exposure to the HPV virus.
• Age: Although it occurs more frequently in people over the age of 40, the incidence is increasing in younger people.
• Alcohol Consumption: Oral cancer is six times more common in those who drink alcohol excessively.
• Diet: People who consume lots of red and processed meat and fried foods are at greater risk.

Symptoms: Alert our office if you notice a change in your mouth such as a sore that doesn't heal or bleeds easily; a lump, thickening, crust or erosion; pain or tenderness; or a change in the way your teeth are positioned. Our office can administer an easy, painless test that detects abnormal cells.

Other symptoms may include unexplained bleeding or numbness in the mouth, difficulty chewing, swallowing or speaking, hoarseness, chronic sore throat or changes in your voice.

Importance of Dental Screenings: In its early stages, oral cancer can often go unnoticed, but visiting our office regularly can ensure that any cancerous cells are detected and treated early. Our office will check your tongue and the area under your tongue, as well as your lips and palate and the back of your mouth.
