Why Are Baby Teeth Important?
Many parents will ask, “Why worry about baby teeth when they are going to fall out?”. Baby teeth (primary teeth) are important because they do not only aid in function of the oral cavity through chewing and speech development, but they also help to hold space for the developing permanent teeth. Excellent dental care helps to aid the developing oral cavity prepare for the emergence of the permanent teeth. When primary teeth get decay, they can lead to dental pain and abscessed teeth. Studies have shown that children with severe decay miss more days of school and have a harder time concentrating in school. It is important for children to build strong preventive habits early on so that they may go on to have excellent dental hygiene as they mature.
Our goals are to help minimize early childhood decay, and restoring teeth that have cavities which may cause children discomfort and pain.
Our doctors will always explain when and why a tooth needs a restoration and how to prevent future cavities from developing through diet and good oral hygiene.
Thumb Sucking and Pacifiers
Sucking is a natural reflex and infants and young children may use thumbs, fingers, pacifiers and other objects on which to suck. It may make them feel secure and happy or provide a sense of security at difficult periods. Since thumb sucking is relaxing, it may induce sleep.
Thumb sucking that persists beyond the eruption of the permanent teeth can cause problems with the proper growth of the mouth and tooth alignment. How intensely a child sucks on fingers or thumbs will determine whether or not dental problems may result. Children who rest their thumbs passively in their mouths are less likely to have difficulty than those who vigorously suck their thumbs.
Children should cease thumb sucking by the time their permanent front teeth are ready to erupt. Usually, children stop between the ages of two and four. Peer pressure causes many school-aged children to stop.
Pacifiers are no substitute for thumb sucking. They can affect the teeth essentially the same way as sucking fingers and thumbs. However, use of the pacifier can be controlled and modified more easily than the thumb or finger habit. If you have concerns about thumb sucking or use of a pacifier, consult your pediatric dentist.
A few suggestions to help your child get through thumb sucking:
- Instead of scolding children for thumb sucking, praise them when they are not.
- Children often suck their thumbs when feeling insecure. Focus on correcting the cause of anxiety, instead of the thumb sucking.
- Children who are sucking for comfort will feel less of a need when their parents provide comfort.
- Reward children when they refrain from sucking during difficult periods, such as when being separated from their parents.
- Your pediatric dentist can encourage children to stop sucking and explain what could happen if they continue.
- If these approaches don't work, remind the children of their habit by bandaging the thumb or putting a sock on the hand at night. Your pediatric dentist may recommend the use of a mouth appliance.
Baby Bottle Tooth Decay (Early Childhood Caries)
One serious form of decay among young children is baby bottle tooth decay. This condition is caused by frequent and long exposures of an infant’s teeth to liquids that contain sugar. Among these liquids are milk (including breast milk), formula, fruit juice and other sweetened drinks.
Putting a baby to bed for a nap or at night with a bottle other than water can cause serious and rapid tooth decay. Sweet liquid pools around the child’s teeth giving plaque bacteria an opportunity to produce acids that attack tooth enamel. If you must give the baby a bottle as a comforter at bedtime, it should contain only water. If your child won't fall asleep without the bottle and its usual beverage, gradually dilute the bottle's contents with water over a period of two to three weeks.
After each feeding, wipe the baby’s gums and teeth with a damp washcloth or gauze pad to remove plaque. The easiest way to do this is to sit down, place the child’s head in your lap or lay the child on a dressing table or the floor. Whatever position you use, be sure you can see into the child’s mouth easily.
Fluoride is an element, which has been shown to be beneficial to teeth. However, too little or too much fluoride can be detrimental to the teeth. Little or no fluoride will not strengthen the teeth to help them resist cavities. Excessive fluoride ingestion by preschool-aged children can lead to dental fluorosis, which is a chalky-white to even brown discoloration of the permanent teeth. Many children often get more fluoride than their parents realize. Being aware of a child’s potential sources of fluoride can help parents prevent the possibility of dental fluorosis.
Some of these sources are:
- Too much fluoridated toothpaste at an early age.
- The inappropriate use of fluoride supplements.
- Hidden sources of fluoride in the child’s diet.
Two and three year olds may not be able to expectorate (spit out) fluoride-containing toothpaste when brushing. As a result, these youngsters may ingest an excessive amount of fluoride during tooth brushing. Toothpaste ingestion during this critical period of permanent tooth development is the greatest risk factor in the development of fluorosis.
Excessive and inappropriate intake of fluoride supplements may also contribute to fluorosis. Fluoride drops and tablets, as well as fluoride fortified vitamins should not be given to infants younger than six months of age. After that time, fluoride supplements should only be given to children after all of the sources of ingested fluoride have been accounted for and upon the recommendation of your pediatrician or pediatric dentist.
Certain foods contain high levels of fluoride, especially powdered concentrate infant formula, soy-based infant formula, infant dry cereals, creamed spinach, and infant chicken products. Please read the label or contact the manufacturer. Some beverages also contain high levels of fluoride, especially decaffeinated teas, white grape juices, and juice drinks manufactured in fluoridated cities.
Parents can take the following steps to decrease the risk of fluorosis in their children’s teeth:
- Use baby tooth cleanser on the toothbrush of the very young child.
- Place only a pea sized drop of children’s toothpaste on the brush when brushing.
- Account for all of the sources of ingested fluoride before requesting fluoride supplements from your child’s physician or pediatric dentist.
- Avoid giving any fluoride-containing supplements to infants until they are at least 6 months old.
- Obtain fluoride level test results for your drinking water before giving fluoride supplements to your child (check with local water utilities).
Teeth Grinding (Bruxism)
Parents are often concerned about the nocturnal grinding of teeth (bruxism). Often, the first indication is the noise created by the child grinding on their teeth during sleep. Or, the parent may notice wear (teeth getting shorter) to the dentition. One theory as to the cause involves a psychological component. Stress due to a new environment, divorce, changes at school, etc., can influence a child to grind their teeth. Another theory relates to pressure in the inner ear at night. If there are pressure changes (like in an airplane during take-off and landing when people are chewing gum, etc. to equalize pressure) the child will grind by moving his jaw to relieve this pressure.
The majority of cases of pediatric bruxism do not require any treatment. If excessive wear of the teeth (attrition) is present, then a mouth guard (night guard) may be indicated. The negatives to a mouth guard are the possibility of choking if the appliance becomes dislodged during sleep and it may interfere with growth of the jaws. The positive is obvious by preventing wear to the primary dentition.
The good news is most children outgrow bruxism. The grinding gets less between the ages 6-9 and children tend to stop grinding between ages 9-12. If you suspect bruxism, discuss this with your pediatrician or pediatric dentist.
