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).

Some of the most important lessons parents and caregivers can give their children involve teaching and demonstrating good oral health habits. The following tips from the Centers for Disease Control and Prevention (CDC) are some ideas for helping you keep your children's teeth healthy.

1. Start cleaning teeth early.
   As soon as a child's first tooth erupts (appears), you should clean it daily by using a clean, damp cloth. Once several teeth are in, you should switch to a small, soft-bristled toothbrush. As for using toothpaste containing fluoride, you typically should start using it to brush your child's teeth at around 2 years old. However, there are some situations in which we recommend using toothpaste earlier than age 2. It just depends on your child’s mouth and development.


2. Use the right amount of fluoride toothpaste.
   Many people are aware that using toothpaste containing fluoride is an important tool for fighting tooth decay. But, many are shocked to discover how much should be used and what could happen if too much is used and swallowed. Because children under the age of 6 may tend to swallow all or some portion of toothpaste, you should only use (and teach them to use) a small amount—about the size of a pea. Otherwise, they could be at risk for getting white spots on their permanent teeth years later from having swallowed too much fluoride. This is also a key reason for teaching children how to rinse and spit properly after brushing their teeth.


3. Supervise brushing.
   Because children's abilities and maturity can vary greatly from child to child, you should brush your children's teeth until they have demonstrated the ability to handle the task alone. However, even when you give them the power to self-brush, you need to monitor them closely to ensure they are doing a thorough job, using the correct amount of toothpaste, and not brushing in a way that could damage teeth or gums. Brushing for too long and too hard are bad habits that can be detrimental to teeth and gums.


4. Talk to your child's doctor and with our office.
   Did you know that your first appointment should be at age one? The age one dental visit can be critical in establishing great communication and trust, and preventing early childhood decay. And having a positive rapport with your dentist and physician is important at any age; however, it is vital for parents and caregivers to develop great communication with their healthcare professionals on behalf of their children from the start of life. Not only does it model good habits for them to observe, but it also helps you stay abreast of the oral and general health needs.

If you suffer from snoring or think you may have Obstructive Sleep Apnea (OSA), did you know that your dentist could play an important role in treating your condition? For most people this is surprising; however, we can provide both education and some treatment options. And as needed, we will work with your other healthcare professionals to get an accurate diagnosis so that you can improve both your sleep and your health.

Oral Appliance Therapy: These devices may look like orthodontic retainers or sports mouthguards, but they are designed to maintain an open, unobstructed, upper airway (tissues at the back of your throat) during sleep. There are many different oral appliances available but less than 20 have been approved through the FDA (Food and Drug Administration) for treating sleep apnea. Depending on your specific condition, we may use it alone or in combination with other means of treating your OSA. Here’s how they work. They reposition the lower jaw, tongue, soft palate and uvula (the tissue in the back of the throat that dangles like a punching bag); stabilize the lower jaw and tongue; and increase the muscle tone of the tongue — unblocking the airway.

Continuous Positive Airway Pressure (CPAP): CPAP bedside machines generate pressurized air delivered through a tube connected to a mask covering the nose and sometimes mouth. Pressurized air opens the airway (windpipe) in the same manner as blowing into a balloon; when air is blown in, the balloon opens and gets wider. This treatment option is generally not used for snoring, but rather for the more serious condition, OSA.

Surgery: Specially trained oral and maxillofacial surgeons may include more complex jaw advancement surgeries. Additionally, an Ear, Nose & Throat (ENT) specialist (otolaryngologist) may consider surgery to remove excess tissues in the throat. It also may be necessary to remove the tonsils and adenoids (especially in children), the uvula, or even parts of the soft palate.

The first step towards getting a great night's sleep if you are a snorer that has never been diagnosed or treated for your condition is to obtain a thorough examination by a physician specifically trained in diagnosing and treating sleep disorders. And depending on the seriousness of your condition, he or she may strongly encourage you to participate in a sleep study. The results from this “study” can provide your dentist and other healthcare professionals with precise data about your snoring, breathing and sleeping habits. This information is key to treating OSA, if you are in fact diagnosed with this condition. Learn more when you read, “Snoring & Sleep Apnea.” Or if you are ready for a thorough examination and to discuss your snoring, contact us today to schedule an appointment.

Do you constantly feel like you are running on empty? Do you snore, feel like napping every day, or even drink multiple cups of coffee just for the caffeine boost? You may have a sleep related breathing disorder (SRBD) or Sleep Apnea (“a” – without; “pnea” – breath) in which your airways become obstructed causing chronic loud snoring. The good news is that we can help both diagnose and treat this disorder, which means you will be able to finally get the rest that you (and your sleeping partner) so desperately need.

The reason that sleep apnea is so disruptive to daily living is that it causes awakening for a few seconds up to 50 times per night, significantly decreasing the amount of deep sleep that is necessary for full rejuvenation. Airway blockage during sleep commonly results from obesity, an enlarged tongue or tonsils, and other factors that can cause your airway to close off when you lie down, all increasing the likelihood that you will suffer from sleep apnea. These conditions are dangerous and impair the brain and heart from receiving adequate oxygen, increasing your risk for both stroke and heart attack.

The study of sleep and its disorders is relatively new. One successful way to treat sleep apnea is with a “CPAP” machine which uses a Continuous Positive Airway Pressure mask overnight to keep air passages open while sleeping. Another more comfortable, less noisy, and unobtrusive method is to use Oral Appliance Therapy, which features an appliance like a retainer that can be custom fitted to your mouth made by a dentist trained in sleep medicine.

And yes, dentists are increasingly being recruited to help study and treat sleep disorders. There are actually several ways in which we can help. Because we see our patients on a regular basis, we are uniquely qualified to diagnose early signs of SRBDs. For example, if you start to snore almost immediately after falling asleep in the dental chair, we will be able to discuss this important warning sign with you. We can also examine the back of your mouth to see if you possess any of the traits that point to SRBDs, including large tonsils and/or an elongated uvula — the tissue in the back of your throat that looks like a little punching bag.

So, if you want to stop snoring and start sleeping well or you think you may have a SRBD, call our office to schedule a basic oral exam and consultation. If you would like to learn more about the link between dentistry and the treatment of sleep disorders, read the Dear Doctor magazine article “Sleep Disorders & Dentistry.”

Nearly everyone has snored at some point in life. However, if your sleeping partner routinely tells you that you suffer from this problem, you really should take action to confirm or deny your suspicions. You may be like one of the 50 to 70 million people in the US alone that suffer from Obstructive Sleep Apnea (OSA), a medical condition in which the upper airway (the back of your throat) collapses during sleep thus limiting your intake of oxygen. And this condition is serious. If left untreated, OSA can lead to a stroke, impotence, an irregular heartbeat, heart attacks, high blood pressure, and other forms of heart disease.

The first and most important step you should take if you snore is to obtain a thorough examination by both your primary-care physician and our office. We have completed specialized training in sleep medicine so that we can not only diagnose but also thoroughly treat your sleep disorders.

If you are diagnosed with this problem, relax. We have many ways we can treat your condition. One of the most common methods is to provide you with oral appliance therapy. This first line of treatment involves our making a customized oral appliance (mouthpiece) that will hold your lower jaw forward. By doing this, we can move your tongue away from the back of your throat so that your airway is less likely to get blocked while you sleep. (It is this blockage that causes the infamous snoring sound.)

Another option we may consider using to treat your sleep apnea if it is moderate to advanced is a Continuous Positive Airway Pressure (CPAP) machine. These machines require you to sleep with a mask over your nose and/or mouth and produce continuous pressure in your windpipe so that your tongue is forced forward away from your airway. Not only can these machines potentially eliminate your snoring, but they can also give you the restful night's sleep that you have been missing.

The last and most permanent solution for treating certain non-responsive cases of sleep apnea is surgery. This option is typically reserved for the most advanced cases to eliminate or reduce an obstruction to the airway.

Ensuring that your children have good oral health is (or should be) the goal of every parent or caregiver. But how confident are you about this topic? The following true/false quiz will help you evaluate your expertise while learning more about keeping your child's teeth healthy.

Questions

1. All children older than 6 months should receive a fluoride supplement every day.
2. Parents should start cleaning their child's teeth as soon as the first tooth appears.
3. Parents should start brushing their child's teeth with toothpaste that contains fluoride at age 3.
4. Children younger than 6 years should use enough toothpaste with fluoride to cover the toothbrush.
5. Parents should brush their child's teeth twice a day until the child can handle the toothbrush alone.
6. Young children should always use fluoride mouthrinses after brushing.

Answers

1. False. Check with your child's physician or dentist about your children's specific fluoride needs. If your drinking water does not have enough fluoride to help prevent cavities, parents of a child older than 6 months should discuss the need for a fluoride supplement with a physician or our office.
2. True. Start cleaning as soon as the first tooth appears by wiping the tooth every day with a clean, damp cloth. Once more teeth erupt, switch to a small, soft-bristled toothbrush.
3. False. Parents should start using toothpaste with fluoride to brush their children’s teeth at age 2. Only use toothpaste with fluoride earlier than age 2 if the child's doctor or our office recommends it.
4. False. Young children should use only a pea-sized amount of fluoride toothpaste. Fluoride is important for fighting cavities, but if children younger than 6 years swallow too much fluoride, their permanent teeth may develop white spots. Using no more than a pea-sized amount of toothpaste with fluoride can help prevent this from happening.
5. True. Because children usually do not have the skill to brush their teeth well until around age 4 or 5, parents should brush their young children's teeth thoroughly twice a day. You should continue doing this until the child can demonstrate a proper brushing technique.
6. False. Fluoride mouthrinses have a higher concentration of fluoride than toothpaste containing fluoride. Children younger than 6 years of age should not use fluoride mouthrinses unless your child's doctor or our office recommends it. Young children tend to swallow rather than spit it out, and swallowing too much fluoride before age 6 may cause the permanent teeth to have white spots.

It is not uncommon to have one or more teeth that are particularly sensitive to heat, cold, or pressure. If you have such a tooth, you probably want to know what caused it and what you can do about it. Here are some frequently asked questions, and their answers.

What causes teeth to become sensitive?
The most common cause of sensitivity is exposure of the tooth's dentin, a layer of the tooth's structure that is just below the outer protective layer (the enamel).

The dentin is sensitive but the enamel layer is not. Why?
The enamel is composed of minerals that are hard and protective. It is not living tissue and has no nerve supply. The dentin layer underneath is bone-like living tissue that does contain nerve fibers. It is protected by enamel above the gum line and by gum tissue in the area of the tooth's root, below the gum line. If the tooth's protective covering is reduced, the nerve fibers in that section of the dentin are exposed to changes in temperature and pressure, which they conduct to the inner pulp layer (nerve) of the tooth. The sensations that reach the tooth's interior pulp layer cause pain.

What causes exposure of the dentin layer in teeth?
Often the dentin is exposed by receding gums, causing areas of the tooth that are normally below the gum surface to be uncovered.

What makes gums recede?
One cause of receding gums is excessive, rough brushing techniques. This is particularly common in individuals who have a family history of thin gum tissues. Removing the film of bacteria called plaque requires only gentle action with a soft brush. This is one reason that we stress the value of learning proper and effective brushing techniques. Gum recession becomes worse after the uncovered dentin of the tooth's root is exposed to erosion from sweet and acidic foods and beverages, such as fruit juices.

Doesn't tooth sensitivity indicate decay?
Decay can also cause tooth sensitivity. As decay destroys a tooth's structure, it eventually invades the inner pulp of the tooth, causing greater and greater pain.

How can you prevent or reduce tooth sensitivity?
As we mentioned above, learn proper brushing techniques; we would be happy to demonstrate them. Use a toothpaste that contains fluoride, which increases the strength of the tooth's protective coating. In more serious cases, we can apply a fluoride varnish or a filling material as a barrier to cover sensitive areas. If you experience long-term tooth sensitivity, make an appointment for an assessment and diagnosis so that we can determine the cause and proper treatment.

Periodontal or gum disease is an often silent disease that can cause significant damage to the health of your teeth and body. The reason it is so often classified as a silent disease is because it is chronic or longstanding and often without any symptoms or pain that most people associate with a disease until it may be too late.

If you think you may have gum disease, here is what to look for:

• Bleeding gums — probably one of the most common and overlooked early warning signs that most people ignore is thinking that the bleeding is being caused by brushing their teeth too hard. The truth is that you would have to brush extremely hard to cause healthy gum tissues to bleed.
• Bad breath — something everyone has experienced; however, it can also be a warning sign of periodontal disease. This is especially true for people who hate or refuse to floss their teeth, thereby trapping literally billions of bacteria where they love to collect in the protected areas between the teeth.
• Redness, swelling, and/or receding gums — all signs of gum disease often accompanied by sensitivity of the gum tissues around the teeth.
• Chronic inflammation — long-standing gum inflammation is a sign that your gum tissues are not healing properly. Periodontal disease exhibits periods with bursts of activity followed by periods where the body tries to recover.
• Loose and/or moving teeth — that seem to be drifting into a new position, are visible signs that you are highly likely to have periodontal disease.
• Abscess formation — late stage gum disease is characterized by painful, swollen, red pockets of pus, which denotes an acute localized periodontal infection.

If you have any of these signs, you need to make an appointment for a thorough evaluation. Otherwise, you could end up losing your teeth to the second most common disease known to man after tooth decay.
