We worry about lots of things after we have children. Are they hungry,
cold, happy, getting enough sleep? Do they have a common cold or is there
something more long standing like asthma? There are so many things to
worry about as our children grow and one very important aspect of a child's
health often gets overlooked. Dental caries (cavities) remain the most
common childhood illness, five times more common than asthma and seven
times more common than hay fever. For the period 1999-2004, 28% of 2-5
year-olds had experienced tooth decay.
The problem known in the medical community as early childhood caries (ECC)
can cause pain, tooth loss, infection, impaired eating, and speech delay.
A child's first set of 20 teeth called primary or baby teeth usually
erupt from six months to three years of age. These primary teeth are gradually
replaced with 32 adult or permanent teeth that commonly erupt between
6 and 21 years of age.
Primary teeth are as important as permanent teeth because:
- Allow children to bite and chew food
- Are critical for proper speech development
- Aid in the development of the facial bones and muscles
- Hold space for the permanent teeth and help guide them into position.
With the importance of these teeth, we need to focus on both prevention
and when necessary treatment. Decay is caused by bacteria with the addition
of sugar that attach to the tooth within plaque that then erode that tooth
enamel. This is easily preventable with the use of fluoride. Fluoride
works by promoting enamel remineralization, reduces enamel demineralization
and inhibits bacterial metabolism and acid production. In certain cities
fluoride is found in the water and therefore no supplementation is necessary.
However in Montana there is no fluorinated water. Most commonly fluoride
is taken systemically with drops, tablets or lozenges or it can be applied
Systemic formulations should be used after the age of 6 months and most
commonly through 3-6 years of age depending on risk. Topical fluoride
varnish is recommended every 3-6 months. Also a topical form of fluoride
is toothpaste and mouth rinses. Under two years of age, fluorinated toothpaste
should not be used. After age 2 a smear (rice sized) of toothpaste on
a toothbrush is appropriate and after the age of 3 a pea sized amount
is recommended. In all cases parents should supervise and help. Over the
counter mouth washes should be held until around 6 years of age when children
are able to swish and spit appropriately.
Other important prevention strategies are not allowing a child to have
a bottle continuously throughout the day or sleeping with a bottle. Other
risk factors are excessive sugar intake, not only from foods/candy but
from sugary drinks (INCLUDING JUICE).
Dental exams also play a big role in the prevention and treatment of ECC.
The recommended age of first dental exam is 12 months old. This visit
mainly focuses on prevention and evaluation of risk for the child. However,
this also allows for early recognition of decay and earlier treatment.
This can decrease problems significantly in the long run.
In a perfect world all of these strategies seem easily accomplished but
there are many barriers. Often young children do not have dental coverage
and if they do have coverage, access to a dentist is difficult. Rural
areas such as ours are often affected by this lack of access. Many kids
have dental coverage under state run plans like Medicaid but there isn't
dental practices in their local area that accept it. In certain situations
a pediatric dentist may be warranted and again there isn't a provider
in close proximity. Also fear over the safety of fluoride decreases the
use of this effective treatment to prevent ECC. Parents are often concerned
about too much fluoride. Most cases of this occur in areas where there
is fluoride in the water in addition to supplementation. In Montana we
do not have fluoride in the water so our risk of too much fluoride is
very low. Too much fluoride can cause white spots or flecks on teeth to
more severe cases that will actually pit the tooth. It takes a fairly
large dose of fluoride for extended periods of time to cause problems
such as this. A three year old would need to ingest 3 pea sized dollops
of adult toothpaste daily over an extended period of time. Child toothpaste
has lower fluoride amount so if the suggested amounts for age are followed,
there is essentially no risk of too much fluoride.
There is no doubt that this is a large problem for our children. With
the help of your family practitioner and dentist, make sure to develop
a plan for your children to protect their teeth. The health of their teeth
now will have major impacts on their health for the rest of their life.
