Grit Your Teeth

How important are your teeth? They can convey emotion, and help you bite, chew, break, and grind food. Teeth shape your face, contri­buting to a pleasant smile. But perhaps you feel your teeth are nothing to smile about.

Comprised of collagen and calcium, teeth are essential to your overall health. This requires that they are free from dental disorders.

Why Too Many Teeth?

Too Many Teeth

How many teeth do you grow in your lifetime? Through age six, deciduous or primary baby teeth number 20. [1] At age six, 32 permanent adult teeth replace baby teeth. [2] An extra 1 to 12 teeth in your mouth is a disorder known as hyperdontia or supernumeraries.

Hyperdontia is manifest by either extra primary or permanent teeth. But extra primary teeth are more common. Men outnumber women with this rare disorder. A prominent indicator of hyperdontia is the growth of extra teeth close to or behind either primary baby or permanent adult teeth. Supernumerary teeth can have atypical shapes and locations. [3]

Overcrowding causes poor alignment or malocclusion, making it difficult to keep teeth clean. This leads to dental caries, bad breath, or gum disease. Sometimes extra teeth exert pressure on jaws and gums, causing swelling and pain. Gingival bleeding, gingival recession, gingival enlargement, and chronic periodontitis result from malpositioned teeth. [4]

What Causes Hyperdontia?

A small jaw or one with the wrong shape prevents all teeth from growing in their proper locations. Hyperdontia and teeth misalignment can both lead to over­crowding. Additional causes include [5]:

  • Genetics (hereditary)
  • Pushing tongue against teeth
  • Teeth grinding (bruxism)
  • Thumb-sucking babies
  • Pacifiers after age two

Treatment For Too Many Teeth

Cosmetic dentistry professionals treat tooth over­crowding. The most common remedy is dental braces. Sometimes the dental arches to which teeth attach do not have enough space. Wisdom teeth often grow impacted or malpositioned. The removal of one or more permanent teeth creates space for other teeth. [6]

Used for gripping and tearing food, cuspids (eye teeth) are larger and stronger than the flat incisors (front teeth). Cuspid roots sink deeply into the bones of the jaw. [7] When maxillary cuspids protrude, an oral surgeon prefers to remove teeth adjacent to them. This allows cuspids to move into position and serve their useful purpose.

Discuss treatment options with your dentist, ortho­dontist, or oral surgeon. Ortho­don­tics is the specialty of dentistry that deals with the correction of too many teeth. An orthodontist can treat over­crowding with devices like braces, Invisalign, dental veneers, and teeth extractions.

With proper care, healthy teeth should last through­out your life­time. Early treat­ment for hyperdontia can keep you smiling longer.
