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).

Temporomandibular Disorder (TMD), which was formerly known as Temporomandibular Joint Disorder (TMJ), is an interesting condition because it can be hard to diagnose and often mimics many other conditions. It arises when there are problems inside the temporomandibular joint, and the muscles attached to it, causing pain. When treating TMD, we typically start by relieving the symptoms of pain and discomfort with heat, mild pain medications, a diet of soft foods, and some simple jaw exercises. We feel that it is critical to address your pain issues as soon as possible before preceding any further with treatment.

Once we have provided some pain relief and after having completed a thorough history and examination, we can move to the next phase of treatment. This may include the introduction of a bite guard or some form of oral appliance therapy. A bite guard is an unobtrusive yet rigid plastic horseshoe-shaped appliance that fits snuggly over the biting surfaces of the upper teeth. When in place and properly adjusted, this custom-made appliance allows your muscles and therefore jaw joints to relax. And it will prevent you from grinding your teeth, another contributing factor to TMD. We will probably ask you to wear it when sleeping or in times when you are feeling stressed when clenching or grinding habits may be active. We may also suggest that you obtain some relaxation therapy and/or biofeedback from a licensed therapist, as this can prove helpful in treating TMD.

If you have suffered from frequent jaw pain in the past and suspect that you may have TMD, please let us know so that we can address it at your next appointment. Or if you are currently in constant or severe pain, contact us immediately to schedule an appointment. You can learn more about the signs, symptoms, and treatment options for TMD by reading “TMD — Understanding The Great Imposter.”

It may alarm some people, but finger or thumb sucking is a completely normal activity for babies and young children. In fact, sonograms often reveal babies sucking a finger or thumb while still in the womb! However, if children are allowed to suck fingers, thumbs or pacifiers indefinitely, it can become problematic, with serious consequences particularly as they get older.

The list below contains important facts about thumb sucking and pacifiers that all parents of young infants should know.

• The American Academy of Pediatric Dentistry recommends that parents and caregivers encourage children to stop thumb sucking by age 3.
• Recent studies have shown that pacifier use after the age of two may cause long-term changes in the mouth; thus these researchers recommend stopping pacifier use by 18 months.
• If thumb and finger sucking habits do not stop soon enough, the upper front teeth may tip toward the lip or not come into the correct position in the mouth.
• Most children who suck their thumbs or fingers tend to stop between the ages of 2 and 4.
• For obvious reasons, a pacifier habit is often easier to break than a finger or thumb-sucking habit.
• One tip for encouraging older children to stop this habit gradually is to use behavior modification with appropriate rewards given at pre-determined intervals to refrain from using a pacifier, or sucking fingers or a thumb.

Be sure to inform us if any of your children suck their fingers, thumb or a pacifier so that we can begin monitoring their development. Our general recommendation is that you schedule an appointment around your child's first birthday.
