A Most Common Habit: Thumb Sucking

What's the most common thing nearly half of American toddlers do when they're teething and tired, relaxing, sleeping or being scolded? They suck their thumbs!

Thumb-sucking is the earliest and most common habit among children. It's nothing for parents to worry about — unless the habit persists. Only after age four does thumb-sucking threaten to damage children's teeth.

Some thumb-suckers simply rest the thumb in the mouth, sucking only at certain times. Others work at the habit, and can displace teeth severely. If, when you remove the thumb from your child's mouth you hear a "popping," it signals a great deal of pressure on the teeth that may cause an overbite or underbite. If the child is over four, you may want to discuss the habit with an orthodontist.

To help break a child of thumb-sucking, parents should;

• Avoid punishing the child
• Provide play materials to occupy the child's hands
• Keep supervision to a minimum
• Keep the home environment happy

One of the worst approaches is parental pressure — it can have a negative effect. On the other hand, peer pressure often works well, encouraging the child to imitate "grown-up" behavior.

Sometimes an orthodontic appliance can prevent or replace a thumb-sucking habit. Once a child becomes accustomed to the appliance, he or see may no longer interested in thumb-sucking.

The first step is to determine when and why a child is thumb-sucking. Your family or pediatric dentist has had lots of experience. Give them a call — they may be able to help.

Stainless Steel Dental Crowns For Children's Molars

Primary (baby) molars with extensive decay, malformed enamel, advanced wear due to grinding, a missing replacement tooth, pulpotomy, or fracture may require coverage with a stainless steel crown in order to provide a durable restoration (filling).

Primary molars are shaped differently than permanent molars. Large amalgam (silver fillings) are not recommended for use in primary molars because they often fracture or crack. A fractured filling may not be evident until it falls out or until the tooth shows signs of abscess (infection). If a filling does fracture, decay may travel to the center of the tooth where the nerve and blood vessels lie. If the infection is caught early enough, a pulpotomy (described later) can be performed. If abscess has occurred, the tooth will often need to be extracted (removed). Early loss of a primary molar can create multiple other problems. Primary molars, and in particular first primary molars with decay on more than one surface, will have the benefit of a much more durable and reliable restoration with a stainless steel crown.

dental crowns. Not only are they more expensive, but the color match and the fit may not be as good. Tooth-colored crowns may appear to be bulky and the acrylic facings can fracture off, leaving exposed metal.

A primary molar may be restored with a stainless steel crown during one appointment. The decay is removed, the tooth is shaped for a crown, the appropriate size crown is selected, and the crown is cemented. The crown must be brushed when brushing the other teeth. Sticky foods such as caramels and taffy can pull the crown off. If this should occur, your pediatric dentist can usually replace the same crown in a few minutes.

A pulpotomy is necessary if bacteria have entered the area deep inside the crown of the tooth because of decay or fracture. This area is called the pulp chamber. It contains nerves, blood vessels, and other tissues that are necessary for the tooth to be healthy. A pulpotomy removes the unhealthy tissues only in the crown portion of the tooth. The nerves, blood supply, and tissues in the root(s) are not removed. If the bacteria are not removed, the tooth will abscess. A medicated filling is placed in the pulp chamber after the infected tissues are removed. A stainless steel crown should be placed in order to provide support for the walls of the tooth.

The tooth is once again healthy and in most cases will last until the Tooth Fairy says it's time to go!
