Why Are My Teeth So Small? Causes And Solution

Like other organs of our body, our teeth also vary in size. Perhaps you have noticed someone from your friends or family having relatively smaller teeth when they smile. You can see more of their gums rather than teeth. These smaller teeth can cause issues with eating and speaking. Figuring out their cause can help you seek the right solution for your gummy smile.

Microdontia

Your genetics are building factors for many things, but did you know they can also affect the size of your teeth? The condition where a person has smaller than average teeth is called Microdontia. Small teeth can have normal or abnormal morphology; dental specialists call them Microdontic teeth or just Microdonts.
They have a regular shape but small size, sometimes normal size but triangular. In certain cases, such Microdonts have small roots, while the crown can be normal.

Causes of Small Teeth

Microdontia can occur for multiple reasons, incorporating genetic, developmental, or environmental effects. Some common Microdontia causes are:

  1. Genetics: genetic characteristics play a major role in deciding the size and shape of your teeth. If you have small teeth running in your family, chances are high that genetics had their hand in your small teeth condition.
  2. Developmental Problems: Specific developmental issues can influence the size of your teeth. The usual growth and formation of your teeth can be interfered with by issues during childhood, like hormonal imbalances or undernutrition.
  3. Dental Issues: Certain dental issues like amelogenesis and enamel hypoplasia can cause unusual development of tooth enamel to make small teeth.
  4. Trauma or injury: Physical injury to the teeth, like a blow in the jaw during soccer, especially in childhood, can disturb the growth period, leaving you with Microdontia.
  5. Poor oral hygiene: Avoiding proper oral hygiene routines, like brushing and flossing, can trigger problems that negatively influence tooth size and dental health.
  6. Dental Flaws: Spacing problems, Malocclusion, and overcrowding in the jaw can disrupt the size and look of your teeth.
  7. Habits and lifestyle: Particular habits such as grinding teeth at night, thumb-sucking in childhood, and many similar oral habits influence the formation and size of teeth.

How to Fix Small Teeth in Adults

Small teeth are usually nothing more than an aesthetic concern; however, if they are causing dental issues to you like wearing and tearing, food trapping due to gaps. Your dental specialist might offer you a few treatment options. Which include:

  • Dental Bonding
    The dentist applies a tooth-colored resin to fix, reshape, or improve the size of your teeth. This can be a good choice if your teeth require mild dental work. It eliminates the need for complicated procedures like crowns to minimize the cost.
  • Dental Crowns
    For sturdier, long-time tooth extensions, your dentist can suggest porcelain crowns. They are like a cap crafted with ceramic, a tailored mold of a tooth to ensure they fit. Crowns, if properly taken care of, can last a lifetime. The only downside is that placing them can require multiple visits to the dental clinic.
  • Dental Veneers
    Composite veneers are less of a dental solution but most of a cosmetic treatment. They conceal the surface of one or multiple teeth to modify your smile to your preference. Veneers are also a good option for getting whiter teeth but cannot offer functional capabilities like dental crowns or bonding.
  • Gum Reshaping
    If your gums spread too far over your teeth, you will likely have a ‘gummy smile.’ A gum lift can fix it. During this procedure, your excess gum tissue will be removed with the help of a scalpel or laser to uncover more of your teeth.
