Tooth Decay that affects children worldwide.
Oral Diseases
IntroductionOral health is one component of general
health and is an important factor in the
normal development of a child. Oral
health problems or illnesses can influence
the general development of a child and
its general health and can adversely
affect quality of life.
Early childhood cariesEarly childhood caries (ECC), also called baby bottle tooth decay or nursing mouth, can destroy your child’s teeth and become a serious mouth infection that can be life-threatening if left untreated.
ECC is the most common chronic
infectious disease of childhood
worldwide. Severe ECC can destroy the
primary teeth; cause painful abscesses
and is the major reason for dental
visits for young children. This condition
disproportionately affects severely the
disadvantaged socio-economic groups.
Infants and toddlers are most susceptible
to ECC and proper oral care goes a long
way in ensuring natural dentition for life.
Early childhood caries, or ECC, is a severe

form of cavities. It is another term for dental decay among infants and chil-dren. It is a very common bacterial infec-tion characterised by severe decay in the teeth. It is a serious and painful dental disease. It can quickly destroy your child's teeth. For the last fifty years, dentists and researchers have struggled to clearly define ECC. Dental decay on infants and children is known by other names as well such as baby bottle tooth decay (BBTD), baby bottle caries, infant caries and bottle rot, nursing caries or nursing bottle syndrome etc. ECC often occurs when your baby's teeth are exposed to sugars for long periods throughout the day. Its prevalence is epidemic. A large body of scientific evidence indicates that ECC is an infectious and transmissible disease. Streptococcus mutans, a group of bacteria, is the primary microbiologi-cal agent in the disease. A major reason for ECC is the limitless breast feeding at night as and when desired after the first primary tooth begins to erupt. ECC is said to cause dental decay of epidemic proportions in certain populations. It is a chronic childhood dental disease. The disease process begins with the transmis-sion of the bacteria to the child, usually
from the primary caretaker, the mother. Mothers with untreated dental disease present a very high risk to their children.
How tooth decay beginsEEC is a chronic and infectious oral disease of young children, most commonly seen in poor and minority populations. Factors such as improper feeding practices, familial socioeconomic background, lack of parental education and dental knowledge, and lack of access to dental care can contribute to and explain why the prevalence of ECC is so great in these select populations.
Tooth decay in children is usually painless until the decay reaches deep into the pulp. If the decay is left untreated, an infection can develop as food from the mouth enters into the tooth pulp.
Disease processBiologically, ECC is an infectious process. Prolonged exposure of sugars, such as those present in milk, formula, and fruit juice, causes damage to the teeth’s surface. The practice of putting a child

to sleep using the bottle at naptime or bedtime exposes sugary fluids that may pool around a baby or child’s teeth for hours. The longer that the sugary liquids come into contact with the tooth’s enamel, the more likely it is for these sugars to combine with bacteria in the mouth.
Baby bottles with fruit juice or milk both contain sugars. When these liquids are in the mouth, bacteria start eating the sugars and then produce acids. These acids cause decay if they remain on teeth long enough. The teeth that get affected initially are the top front teeth.
Early childhood caries can occur if your child:
• is put to bed with a bottle filled with any liquid other than plain water
• drinks from a bottle filled with sugary liquids or milk during the day
• receives a pacifier dipped in sugar, honey or a sweet liquid
Normal breastfeeding has not been shown to cause dental cavities. However, breastfeeding for long periods of time can still put your child at higher risk for dental decay.
Remember, it's not just what your baby is drinking, but how often. Longer the time liquids (other than water) remain in a baby's mouth, the higher the risk. This is why it is dangerous to let your baby go to sleep with a bottle or use a bottle as a pacifier during the day. The teeth most often affected by ECC are the upper front teeth. But others can decay, too.
Tooth decay can occur much more easily if there are large numbers of cavity-causing bacteria living in your child's mouth. One of the most dangerous types of cavity-causing bacteria is Streptococcus mutans. In the mouths of children with no or little tooth decay, S. mutans makes up less than 1% of the mouth's bacteria.
But in children with ECC, it makes up more than half the bacteria.
S. mutans is common. It is passed from parent to child, usually when a child is between 6 and 31 months old. Keeping your own mouth healthy and free of cavities can help your child's mouth stay healthier, too.
The top front teeth usually are the first ones affected by ECC. Often, the cavities start on the backs of the teeth. The top teeth farther back in the mouth are affected next. Finally, the bottom back teeth get cavities. The lower front teeth usually do not
get cavities. These teeth are covered by the tongue, which keeps liquids away. These teeth also are close to large salivary glands, so they are bathed in saliva. Saliva helps wash away sugars and bacteria.
Decayed teeth that are not fixed can
cause pain and infection. Teeth that
are very badly decayed may need to
be removed. Tooth decay is a bacterial
infection, and it can spread if it is not
treated. Also, the permanent teeth under
the gum can be affected if the decay is
not treated.
Factors causing ECCFactors such as improper feeding practic-es, familial socioeconomic background, lack of parental education and dental knowledge, and lack of access to dental care can contribute to ECC. The preva-lence of ECC in children, ages three to five years, in US is reported to be as high as 90%. In developing countries ECC is a critical problem as well, heightened by extraneous factors such as low income or malnutrition. The prevalence of ECC in these countries is reported to be as high as 70-80%. Untreated caries may lead to early loss of the primary denti-tion and affect the growth and matura-tion of the secondary, adult dentition. In
fact, decay in the primary detention is the best predictor for decay in
the secondary dentition; poor dental health and disease
often persist to adulthood, affecting speech articula-tion, growth, and dietary practices. At the most extreme of cases, ECC can also lead to ram-pant decay, infection, pain, abscesses, chew-ing problems, malnu-trition, gastrointestinal disorders, and low self-
esteem. Children with ECC are shown to have
an elevated risk for new le-sions as they get older, both
in the primary and permanent dentitions.
Here are some tips on preventing early childhood caries:
• Don't put your baby to bed with a bottle unless it is filled with plain water. Even watered-down fruit juice or milk can increase the risk of decay.
• Talk with your doctor about weaning your infant from the bottle when he or she is 12 to 14 months old.
• During the day, don't use a bottle to comfort your baby unless it's filled with plain water.
• Don't dip your baby's pacifier in sugar or sugary liquids.
