Q: What is the best toothpaste for my child?
A: Tooth brushing is one of the most important tasks for good oral health. Many toothpastes, and/or tooth polishes, however, can damage young smiles. They contain harsh abrasives, which can wear away young tooth enamel. When looking for a toothpaste for your child, make sure to pick one that is recommended by the American Dental Association as shown on the box and tube. These toothpastes have undergone testing to insure they are safe to use.
Use only a smear of toothpaste (the size of a grain of rice) to brush the teeth of a child less than 3 years of age. For children 3 to 6 years old, use a "pea-size" amount of toothpaste and perform or assist your child’s toothbrushing. Remember that young children do not have the ability to brush their teeth effectively on their own. Children should spit out and not swallow excess toothpaste after brushing.
Q: Why does my child grind his teeth at night (bruxism)?
A: 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 decreases 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.
Q: What is pulp therapy?
A: The pulp of a tooth is the inner, central core of the tooth. The pulp contains nerves, blood vessels, connective tissue and reparative cells. The purpose of pulp therapy in Pediatric Dentistry is to maintain the vitality of the affected tooth (so the tooth is not lost).
Dental caries (cavities) and traumatic injury are the main reasons for a tooth to require pulp therapy. Pulp therapy is often referred to as a "nerve treatment", "children's root canal", "pulpectomy" or "pulpotomy". The two common forms of pulp therapy in children's teeth are the pulpotomy and pulpectomy.
A pulpotomy removes the diseased pulp tissue within the crown portion of the tooth. Next, an agent is placed to prevent bacterial growth and to calm the remaining nerve tissue. This is followed by a final restoration (usually a stainless steel crown).
A pulpectomy is required when the entire pulp is involved (into the root canal(s) of the tooth). During this treatment, the diseased pulp tissue is completely removed from both the crown and root. The canals are cleansed, disinfected and, in the case of primary teeth, filled with a resorbable material. Then, a final restoration is placed. A permanent tooth would be filled with a non-resorbing material.
Q: What is the best time for orthodontic treatment?
A: Developing malocclusions, or bad bites, can be recognized as early as 2-3 years of age. Often, early steps can be taken to reduce the need for major orthodontic treatment at a later age.
Stage I – Early Treatment: This period of treatment encompasses ages 2 to 6 years. At this young age, we are concerned with underdeveloped dental arches, the premature loss of primary teeth, and harmful habits such as finger or thumb sucking. Treatment initiated in this stage of development is often very successful and many times, though not always, can eliminate the need for future orthodontic/orthopedic treatment.
Stage II – Mixed Dentition: This period covers the ages of 6 to 12 years, with the eruption of the permanent incisor (front) teeth and 6 year molars. Treatment concerns deal with jaw malrelationships and dental realignment problems. This is an excellent stage to start treatment, when indicated, as your child’s hard and soft tissues are usually very responsive to orthodontic or orthopedic forces.
Stage III – Adolescent Dentition: This stage deals with the permanent teeth and the development of the final bite relationship.
Q: When will my baby start getting teeth?
Teething, the process of baby (primary) teeth coming through the gums into the mouth, is variable among individual babies. Some babies get their teeth early and some get them late. In general, the first baby teeth to appear are usually the lower front (anterior) teeth and they usually begin erupting between the age of 6-8 months.
