Have Teeth that are Too Big or Too Small?

Although not frequently common, you may know someone or yourself experience having a tooth or teeth that are smaller or larger than normal in size. When adult permanent teeth appear to be smaller, or similar to the size of baby teeth, this condition is known as Microdontia. Microdontia commonly affects the upper lateral incisors, and are often referred to as peg laterals. On the other hand, if the teeth are larger than usual, this is known as Macrodontia. When every tooth is affected by Macrodontia, this is typically due to the rare condition pituitary gigantism, which is seen in children and affects other parts of the body such as the feet and hands. Both conditions have been mainly associated with genetics. However, other causes including certain syndromes, unilateral facial hypoplasia, gigantism, and hormonal imbalance, for instance, could be contributing factors.

Macrodontia and Microdontia can create some issues for people, including crowding or excess space, teeth misalignment, and even impact someone’s confidence in smiling. The discrepancy between the upper and lower relationship of teeth when biting together as a result of macrodontia or microdontia could cause individuals to have trouble chewing or speaking. It can also lead to excessive wear on the teeth. Luckily, there are ways to correct macrodontia and microdontia with certain treatment options.

For Microdontia:

  • Composite Restorations: Composite, a tooth-colored filling material can correct the shape and size of teeth by bonding to the tooth.
  • Dental Veneers: Veneers are custom-made to cover the front surface of teeth to help improve one’s smile. They are made of a combination of porcelain or ceramic materials that match the color of teeth.
  • Dental Crowns: If a tooth is shaped abrnomally crowns can help cover teeth and help fix the tooth size discrepancy.

For Macrodontia:

Some cases may not need treatment, unless wanting to treat for esthetic reasons. If Macrodontia has caused crowding, orthodontics (braces) or other restorative treatments may help create the proper bite and improve esthetics. Teeth may also be contoured to a smaller size or different shape depending on the severity of the case.

Extraction may be recommended if the tooth affected by Macrodontia does not erupt into the mouth.
