THUMB SUCKING

Thumb Sucking Appliances

The majority of children naturally outgrow their thumb-sucking habit.
However, children who continue to thumb suck after the age of five or six (especially vigorously) risk oral complications. These complications include: narrowed arches, impacted teeth, and misaligned teeth. The “palatal crib” appliance usually stops thumb sucking immediately.

The “crib” is crafted and affixed to the teeth by the pediatric dentist, almost like a barely visible set of dental braces. Preventing the thumb from reaching the roof of the mouth reduces gratification – and breaks the habit very quickly.
Removable variations of the “crib” are also available, and can be used depending on the age of the child and his or her willingness to cooperate.

Expansion Appliances

An overbite, where the upper front teeth protrude over the lower front teeth, can be corrected with an expansion appliance, as can a crossbite. The expansion appliance is used to stretch and widen the arch, providing enough space for the teeth to be realigned in a straight manner. Expansion appliances are custom-made, and can be affixed to the inside or the outside of the teeth. Children born with a cleft palate may be required to wear an expansion appliance to prepare the jaw for oral surgery.

Pacifiers and Thumb Sucking

For most infants, the sucking of thumbs and pacifiers is a happy, everyday part of life. Since sucking is a natural, instinctual baby habit, infants derive a sense of comfort, relaxation, and security from using a thumb or pacifier as a sucking aid.

According to research from the American Academy of Pediatric Dentistry (AAPD), the vast majority of children will cease using a pacifier before the age of four years old. Thumb sucking can be a harder habit to break and tends to persist for longer without intervention. Children who continue to suck thumbs or pacifiers after the age of five (and particularly those who continue after permanent teeth begin to emerge) are at high-risk for developing dental complications.

How can thumb sucking and pacifier use damage children’s teeth?

Pacifier and thumb sucking damage can be quite insidious. Both can be difficult to assess with the naked eye, and both tend to occur over a prolonged period of time. Below is an overview of some of the risks associated with prolonged thumb sucking and pacifier use:

Jaw misalignment – Pacifiers come in a wide range of shapes and sizes, most of which are completely unnatural for the mouth to hold. Over time, pacifiers and thumbs can guide the developing jaws out of correct alignment.

Tooth decay – Many parents attempt to soothe infants by dipping pacifiers in honey, or some other sugary substance. Oral bacteria feed on sugar and emit harmful acids. The acids attack tooth enamel and can lead to pediatric tooth decay and childhood caries.

Roof narrowing – The structures in the mouth are extremely pliable during childhood. Prolonged, repeated exposure to thumb and pacifier sucking actually cause the roof of the mouth to narrow (as if molding around the sucking device). This can cause later problems with developing teeth.

Slanting teeth – Growing teeth can be caused to slant or protrude by thumb and pacifier sucking, leading to poor esthetic results. In addition, thumb sucking and pacifier use in later childhood increases the need for extensive orthodontic treatments.

Mouth sores – Passive sucking is much less harmful than aggressive sucking. Aggressive sucking (popping sounds when the child sucks) may cause sores or ulcers to develop.

If you do intend to purchase a pacifier:

  • Buy a one-piece pacifier to reduce the risk of choking.
  • Buy an “orthodontically correct” model.
  • Do not dip it in honey or any other sugary liquid.
  • Rinse with water (as opposed to cleansing with your mouth) to prevent bacterial transmissions.
