DRY MOUTH & SJOGREN'S SYNDROME
Every day, over a 24 hour period, the average person produces at
least 500mL of saliva. In fact a normal person will make 5mL every
minute when they are eating or chewing. This is not the case in
patients with Dry Mouth Syndrome (Xerostomia) or Sjogren's
Syndrome. These people suffer due to the inadequate saliva
quality they produce and the inadequate saliva volumes they produce.
What are
the Functions of Saliva
Saliva is a natural cleansing agent of teeth and gums. It
helps to wash away accumulated food after eating, debris, bacteria
and plaque. saliva lubricates the soft tissues of the mouth
including gums, tongue, palate, floor of mouth, cheeks and lips, and
throat. Saliva enables swallowing by lubricating the throat area.
Saliva also contains certain chemicals and compounds beneficial to
us. Saliva contains proteins such as amylase (a digestive
enzyme) to start break down of starch in food. saliva contains
immunoglobulins which help counteract infections and the stickiness
of bacteria adhering to teeth and soft tissue. Saliva contains
calcium and phosphate, which help to remineralise teeth making them
less susceptible to dental decay. Saliva contains buffering (acid
soaking up) systems which neutralise and inhibit the effects of acid
produced by oral bacteria or which are included in the diet.
What are
the Symptoms of Dry Mouth
Although symptoms are very general in nature, patients tend to
report the following symptoms. the lips may become dry sore and
cracked, similar to wind burn. the tongue may also become dry and
have a burning sensation. Saliva glands situated around the mouth,
under the tongue and below the ear, may become swollen and tender.
Small sores or cracks can occur in the corners of the mouth. These
are known as Angular Cheilitis. All the soft tissues of the oral
cavity may be thinner and therefore more susceptible to damage.
Taste sensation can be altered because of inadequate liquid to
dissolve tastants in the food so that taste buds can be activated
Sufferers of Dry Mouth Syndrome and Sjogren's Syndrome show more
secondary infections, such as yeast infections (thrush) caused by
bacteria such as Candida Albicans. This thrush presents clinically
as generalised inflammation of the skin surfaces of the mouth and
tongue on which there are small superficial whitish patches. These
patches may be removed leaving a red area underneath which often
bleeds easily. The KFORCE Kit can help to remove thrush and prevent
its reoccurence.
Patients report tender burning mouth sensations made worse by hot or
spicy foods. Patients that wear dentures find that wearing and fit
of the dentures is worse. This is because lack of saliva means
that the dentures do not get an adequate seal. Finally patients
present with increased decay levels.
Patients may report a metallic taste in the mouth and thin
frothy saliva. They also may report increased bad breath.
The more dry your mouth, the more chance you will have bad breath.
It has to do with the amount of oxygen available in your saliva. The
bacteria that cause bad breath, thrive in an anaerobic (no oxygen)
environment. When your mouth gets dry, your saliva disappears or
gets thicker, representing the reduction of Oxygen. When the
bacteria senses this difference, they start to produce Volatile
sulphur Compounds.
How do we
Manage Dry Mouth
Fluid Replacement and Mouth Moistening. This is necessary to
diminish soreness in the mouth and oral discomfort. Also to to aid
speech and swallowing.
It
is recommended to chew chewing gum to stimulate saliva glands. This
gum should ideally have Xylitol added to it and also be sugar
free to avoid decay. We recommend Recaldent Chewing Gum which
comes in both Mint and Tropical flavours. One stick or two pellets
can be chewed for 20 minutes after meals.
Glandular massage. Massaging the salivary glands can reduce
tenderness. this tenderness is due to thickened viscous saliva
secretions that become retained in the salivary ductal system.
Saliva substitutes. This is especially important if there is no
saliva gland function, or the saliva tissue has been removed.
Substitute saliva with water. This is probably the simplest thing we
can do. We recommend two glasses of water after meals or sipping as
necessary during the day. Other oral lubricants such as Breeze
Morning Fresh Oral Gel are also excellent. This gel has many
ingredients which not only aid in soothing damaged tissue but also
lubricate tissue extremely well.
Use
Anticariogenic Aids such as Recaldent Mousse to cover the
teeth at night and help stop decay. Recaldent Mousse contains the
same active ingredients as Recaldent Gum. It aids in remineralising
tooth structure whilst also aiding in stopping adhesion of plaque
film to the tooth surface. Plaque film contains bacteria, sugars and
acids that damage teeth.
Pilocarpine. This drug appears to be a useful salivary stimulant
but has side effects. The patient needs to be screened for heart
disease and diabetes and other medications first. These side effects
can make this drug unacceptable in most cases. But we mention it
here for completeness.
Avoid acid juices and carbonated drinks. Most commercial soft
drinks, processed juices or fluid replacement drinks are acid in
nature. This is done to keep them stable. Due to lack of saliva
buffering abilities these drinks should be avoided.
Avoid oral swabs such as Lemon and Glycerine Mouth Swabs designed to
"freshen the mouth"
Avoid difficult to eat foods such as bread and chicken
Avoid in between meal snacks which are high in carbohydrate as these
contain sugars which encourages dental plaque and decay.
Continued speaking
during the day, causes your saliva to thicken
representing the onset of more dry mouth. This eventually leads to
bad breath production. By the way, from the age of 25 on, we all
begin producing less saliva. It goes downhill from that point on, so
there is always a greater chance to produce more bad breath as we
all get older.
Smoking is a major
factor in dry mouth.
When you smoke you are effectively
starving the mouth of oxygen, thus promoting the overgrowth of
anaerobic bacteria that create the smelly sulphur products.
Unfortunately smoking is addictive and therefore not easy to cut
down or quit. Smoking effectively
decreases the ph level of your mouth and dries your oral tissues. Consider that if
you smoke you need to be paranoid about your breath. It is therefore
essential that all smokers use some form of breath system as well as
chewing gum during the day to help keep adequate supply of saliva
and oxygen to the mouth.
Alcohol causes dry
mouth. Alcohol can turn occasional bad breath into horrible bad
breath and lousy taste. It doesn't matter if the alcohol is wine or
beer, or even in mouthwash, that can be bought over the counter. Alcohol
makes the mouth extremely dry very rapidly, and this can lead to
instant halitosis. Did you know that some commercial mouth rinse
contain up to 26% alcohol whereas wine only contains 11%
If you snore,
or mouth breath, you are
making your mouth, tongue and throat very dry during the
evening. This is when most sulphur compounds are produced. Because
mouth breathing dries off the tongue, it can also be a serious
initiator of bad breath.
