Thumb sucking habit could result in misaligned teeth and bite issues!!

Thumb sucking habit is common in babies and young children. It can have a soothing and comforting effect and kids generally break the habit naturally. However, if the children are still continuing to suck their thumbs by the age 5-6 when permanent teeth are beginning to erupt, there may be reason to be concerned. Prolonged thumb sucking can have lasting negative effects on teeth and overall health.

Thumb sucking can lead to various orthodontic problems:

  1. It can lead to growth impediments of the upper jaw, frequently modifying the natural shape of the upper jaw and arch to a narrower one, and oftentimes a higher palate due to excessive pressure of the tongue and finger. Another linked orthodontic sequelae is a reverse fit of posterior (or back) top and bottom teeth – or create a posterior ‘crossbite’.
  2. Prolonged thumb sucking can also create an ‘open bite’, or a malocclusion defined by the front top and front bottom teeth not touching (not meeting or overlapping together) when the child is fully biting. This occurs because the constant force on the upper front teeth from a thumb sucking habit tent to ‘procline’ (or over tilt forward) and ‘intrude’ (or move up vertically) them.
  3. Another common orthodontic problem that can be created from prolonged thumb sucking habit is excessive ‘overjet’ (or space between upper and lower front teeth in the front to back dimension). This occurs due to excessive forward pressure of the finger with the thumb sucking habit) on upper front teeth.
  4. Prolonged thumb-sucking habits can also lead to skin problems and excessive exposure to germs. Constant exposure to saliva and moisture in the mouth can make the skin more vulnerable to other injuries and may result in callous formation on the preferred thumb. Furthermore, since children wash their hands infrequently and hence more exposure to germs may result in the children becoming sick more frequently.
  5. Since thumb sucking adversely affects the alignment of the teeth and jaw development, thumb sucking may lead to lisp and speech impediments. Frequently, Ts and Ds are more challenging to pronounce, and this may affect sound articulation while speaking. Children with prolonged finger habits may require speech therapy and may even have social ramifications.

The American Association of Orthodontists recommends that children are evaluated by an orthodontist by the age of 7 in order to screen for habit related and well as other pertinent dental issues that affect dental health, development, and growth. Please schedule your complimentary orthodontic evaluation in order for a comprehensive assessment of your child’s orthodontic needs.
