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).

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.

Every parent, caregiver, coach, sports fan and especially injured party dreads the moment when an injury to the mouth occurs during a sporting event. The first thought observers have after looking closely to see if it is their child or someone they know is, “I hope someone knows what to do!” Do you know what to do in case of a dental sports emergency? Test your dental injury IQ with this simple, quick quiz. The answers are listed at the bottom of this article.

Dental Injury IQ

1. If a tooth (including its root) is totally knocked out, what can you safely store it in while finding a dentist within 5 minutes of the injury?
1. Water or salt water
2. Milk (preferably cold)
3. Inside the cheek (mouth) of the injured person
4. All of the above
2. True or False: Immediately following the injury, fresh cold tap water or bottled water is the best way to remove debris from where a tooth was knocked out.
3. If a tooth has shifted from its original position following an injury, you should...
1. See a dentist within 5 minutes
2. See a dentist within 6 hours
3. See a dentist within 12 hours
4. Only see a dentist if the tooth is not better in a few days
4. True or False: You treat a knocked out baby tooth in the same manner as you do a permanent tooth.
5. The most important thing to do to save a tooth that has been completely knocked out of the mouth is to…
1. See a dentist as soon as possible
2. Replant the tooth within 5 minutes
3. Stop the bleeding before re-planting the tooth
4. Rinse the tooth with fresh, clean water

The Answers

1) d = all of the above, 2) true, 3) b = see a dentist within 6 hours, 4) false – baby teeth are typically not replanted, 5) b = replant the tooth within 5 minutes

Dental caries (tooth decay) is similar to the pesky bumblebee that invades your lovely summer barbecue. You can find temporary solace from this intruder by eliminating that very first bee that you see, but if you are situated in an area that is close to the bee's nest, it won't be long before the next bee buzzes along. This is similar to tooth decay. Having one cavity-laden tooth drilled and filled is really just a temporary fix. The underlying conditions that led to tooth decay in the first place need to be addressed in order for your risk of future infection to decrease.

Researcher Dr. John Featherstone created the concept of the Caries Balance in 2002, in which he explained that tooth decay and overall dental health are dependent upon a proper balance of disease-causing and health-promoting factors. Discovering what the fundamental problem really is (and getting as far away from that hornet's nest as possible) can help both determine and curb your risk for future tooth decay.

Here's the issue in a nutshell: Susceptible teeth, in the presence of acid producing bacteria when fed by sugar from your diet, basically, will create all the conditions necessary to cause tooth decay.

To determine your risk for tooth decay, see how many times you answer “Yes” to the following questions:

1. Do you brush your teeth twice a day to reduce bacterial plaque sticking to the teeth?
2. Do you use fluoride toothpaste to strengthen the teeth against acid attack?
3. Do you use a fluoride mouthrinse?
4. Do you floss daily?

Every affirmative answer decreases your risk of getting cavities, but even doing all of this may not be enough!

Now, how many times can you answer “Yes” to these questions?:

1. Do you smoke? Smoking causes mouth dryness, and creates a host of other health problems.
2. Do you snack frequently between meals? One sugary snack and your mouth is acidic for the next hour. One snack per hour and your mouth is acidic all day.
3. Do you frequently have acid reflux or heartburn? Reflux creates extreme acidity in the mouth and directly erodes tooth enamel.
4. Do you drink soda, sports drinks, or acidic beverages frequently? These beverages are very acidic.
5. Is your mouth frequently dry? Do you take any medications that cause mouth dryness? Saliva is nature's own defense against acidity and helps neutralize acid in the mouth.
6. Have you had frequent cavities in the past and/or have you had any crowns or fillings in the past three months? The best indicator of future disease is past disease!

Every affirmative answer increases your risk of getting cavities!

Now that you are a little more knowledgeable about your personal risk for tooth decay, make an appointment with us to discuss the preventative measures that can give you some control over the future condition of your teeth. Ignoring the risks and then ending up with a mouth full of rotting teeth when you knew better could really sting a little!

Given the fact that baby-boomers are now reaching the age of retirement, understanding senior healthcare is becoming a top priority to many people. Discover your level of expertise in the area of oral health by taking the following true/false test.

True or False Self Assessment

1. All people eventually lose their teeth as they age.
2. Yellow teeth are a sign of gum disease.
3. If you have dentures, you no longer need regular dental check-ups.
4. Periodontal (gum) disease is a big problem that affects 3 out of 4 adults.
5. Electric toothbrushes can be a great option for seniors with arthritis or other debilitating conditions.

Answers

1. False: Your teeth are meant to last your lifetime.
2. False: Yellow teeth typically denote stained teeth from diet, medication, smoking, or growing older. And while they may not appear attractive, older, yellow teeth can in fact be healthy and free of gum disease. However, if your yellow teeth bother you, ask us if teeth whitening could be right for freshening up your smile while making you appear younger.
3. False: For those individuals who wear complete upper and lower dentures, you will always need routine dental exams, typically once a year so that you can be screened for cancer, as well as other oral conditions (i.e. candadiasis), to ensure the you obtain and maintain optimal oral health.
4. True: 75% of all adults over the age of 35 will experience some form of periodontal disease, a condition in which the gums become inflamed and infected. If left untreated, gum disease causes the bone that supports the teeth to deteriorate until the teeth are loosened and/or eventually lost (either they fall out on their own or must be removed). On a positive note, you can prevent gum disease by having good oral hygiene that includes flossing daily and brushing at least twice a day with a proper technique and fluoride toothpaste.
5. True: Under normal conditions, what matters most is not so much the type of toothbrush used (manual, electric or battery powered toothbrush), but rather how you use it. However, if you are unable to use a manual toothbrush effectively for proper brushing, then a power toothbrush may be able to facilitate proper cleaning more easily.
