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).

While some people associate the need for root canal treatment with an injury or trauma to a tooth (which is a valid cause), it can also most commonly be caused by tooth decay that is left untreated. This is the reason why we have put together this brief guide to explain the three common stages of tooth decay that lead up to the need for a root canal.

Stage 1: During this stage, decay begins to form in the tiny grooves on the biting surface of a tooth or where the teeth contact each other. The result is loss of the surface enamel of the tooth.

Stage 2: Left untreated, the disease progresses through the enamel and into the dentin, which forms the body of the tooth. Once in the dentin, it progresses more rapidly until it reaches the pulp — the living tissue within the root canals of the tooth. The decay infects the pulp tissues, which contain the nerves of the teeth, causing pain. The end result of inflammation and infection of the pulp is that it dies.

Stage 3: As the nerve dies an infection results, which causes pain and swelling. For some people who do not regularly visit our office, this may be the first physical sign that they have a problem. But all is not lost, a successful root canal treatment, whereby the infected pulpal tissue is removed and the root canals are cleaned and sealed will not only relieve the pain, but save your tooth. So the good news is that once a tooth has had the appropriate endodontic treatment (“endo” – inside; “dont” – tooth) followed by a proper restoration, the tooth can last as long as your other teeth. The key is to take proper care of your teeth, have routine cleanings, and visit our office as soon as you feel you have a problem with a tooth.

If you are having pain or symptoms from a tooth or teeth, check it out with us — you may or may not need a root canal treatment. Contact our office to schedule an appointment and find out. Don't wait until it's too late. And to learn more about the signs, symptoms, and treatments for a root canal, read the article “I'd Rather Have A Root Canal....”

A number of factors can lead to dental caries (tooth decay). To find out if you are at high risk, ask yourself these questions.

Is plaque visible in my mouth?
Dental plaque is a whitish film of bacteria that collects on your teeth. If it is clearly visible, it means that there is a lot of it. Among the bacteria in the plaque are those that produce tooth decay, particularly in an acidic environment. (A normal mouth is neutral, measured on the pH scale, midway between the extreme acidic and basic ends of the scale.)

Do I have a dry mouth?
Saliva protects your teeth against decay by neutralizing an acidic environment and adding minerals back to the outer surface of enamel of your teeth, so reduced saliva is a high risk for caries. Many medications can cause dry mouth as a side effect.

Do I eat a lot of snacks, particularly unhealthy ones?
Frequently eating sugars, refined carbohydrates, and acidic foods promotes the growth of decay-producing bacteria. The more frequently you eat, the longer your teeth are bathed in sugars and acids. Acidic foods not only promote bacterial growth, they also directly cause erosion of the tooth's hard surface by softening and dissolving the minerals in the enamel.

Do I wear retainers, orthodontic appliances, bite guards or night guards?
These appliances are recommended for various conditions, but they tend to restrict the flow of saliva over your teeth, cutting down on the benefits of saliva mentioned above.

Do my teeth have deep pits and fissures?
The shape of your teeth is determined by your heredity. If your teeth grew in with deep grooves (fissures) and pits in them, you are at higher risk for bacterial growth and resulting decay.

Do I have conditions that expose my teeth to acids?
If you have bulimia (a psychological condition in which individuals induce vomiting), or GERD (Gastro-Esophageal Reflux Disease), your teeth may be frequently exposed to stomach acids that can cause severe erosion to your teeth.

Do I already have cavities?
Visible cavities can range from those only visible with laser technology or x-ray examination to those a dentist can see with a naked eye. If you already have small cavities, you are at high risk for developing more.

Do I have white spots on my teeth?
White spots are often the first sign of decay in a tooth's enamel. At this point, the condition is often reversible with fluorides.

Have I had a cavity within the last three years?
Recent cavities point to a high risk of more cavities in the future, unless conditions in your mouth have significantly changed.

If you have any of these indications of high risk, contact us today and ask us for suggestions for changing the conditions in your mouth. You can also learn more by reading the Dear Doctor magazine article “Tooth Decay.”

When it comes to sports, all athletes need to know how to assess their risk for experiencing a sports-related injury as well as how to prevent one. The first step to accomplish this is learning how sports and activities are classified, as they define risks from little-to-no chance of injury to highly susceptible for injuries. These categories include:

• Low velocity, non-contact sports: These sports and activities have the lowest risk, as they typically include sports where the athletes perform individually at reasonable speed without physical contact. Examples include: golf, Nordic skiing, weight lifting, running and swimming.
• High velocity, non-contact sports: These sports and activities are those where athletes move at high rates of speed but with no contact with other participants. While there is no contact, anytime you are moving at high rates of speed, accidents can happen. Examples include: bicycling, motocross, skateboarding, skiing and snowboarding.
• Contact sports: As the title states, these sports and activities include frequent body-to-body contact or body to equipment (e.g., a ball, glove, etc.) contact. Examples include: basketball, soccer, lacrosse, baseball and softball.
• Collision sports: With these sports and activities, strong, forceful, body-to-body or body-to-equipment contact is a primary goal of the sport. Examples include football, ice hockey, rugby, and boxing. Without the proper protective head and mouth gear, participants are highly likely to experience an oral-facial and/or head injury.

The good news is that you can dramatically reduce the odds of serious dental and oral-facial injury by ensuring that you wear a professionally made mouthguard in addition to a helmet, facemask, or other protective gear that is appropriate to the sport. This is especially true if you participate in the high velocity, contact and collision categories. These simple steps can help reduce worries for not only players, but also for parents, caregivers and coaches.

Both diabetes and gum (periodontal) disease are chronic inflammatory diseases that have negative consequences for millions of people worldwide. But before we continue, let's define these two diseases:

Periodontal disease is a condition in which biofilms of dental bacterial plaque stick to teeth near the gum lines causing the gum tissues to become inflamed and infected. If not treated properly and in an early stage, it can cause severe damage to the bone that supports the teeth, resulting in tooth loss. It occurs in the absence of good oral hygiene which includes ineffective daily brushing and flossing and neglecting to see your dentist.

Diabetes is a chronic condition in which blood glucose (sugar) levels become excessive. Glucose is the body's main source of sugar for energy. The hormone insulin, among other mechanisms, normally controls glucose. Prolonged elevated blood sugar levels are harmful and ultimately can even be life threatening if left untreated. With type 1 diabetes, insulin injections (shots) are required to maintain the proper blood sugar levels because the body no longer produces its own blood sugar. Type 2 diabetes is generally less severe and can usually be treated with a combination of diet and medication.

And while both of these diseases share the same common enemy, you, there is scientific evidence revealing links between the two. Diabetes increases the risk factor for developing periodontitis, and conversely, periodontal disease makes it more difficult for diabetics to control blood glucose levels.
