Crooked Teeth


msBahasa Malaysia


What are crooked teeth?

There are several reasons why some people’s teeth grow in crooked, overlapping, or twisted. Some people’s mouths are too small for their teeth, which crowds the teeth and causes them to shift. In other cases, a person’s upper and lower jaws aren’t the same size or are malformed, resulting in either an overbite, when there is excessive protrusion of the upper jaw, or an under bite, when the lower jaw protrudes forward causing the lower jaw and teeth to extend out beyond the upper teeth.

Moreover, crooked teeth can:

  • Interfere with proper chewing.
  • Make keeping teeth clean more of a challenge, increasing the risk of tooth decay, cavities, and gingivitis.
  • Strain the teeth, jaws, and muscles, increasing the risk of breaking a tooth.
  • Make people feel self-conscious about their appearance and affect their self-esteem.

The teeth won’t be able to perform vital functions if they’re misaligned. Learn more about this issue and how it may be treated, to protect your overall oral and digestive health.

  • Class 2: Class 2 crooked teeth is diagnosed when a severe overbite is present. This condition, known as retrognathism (or retrognathia), means that the upper teeth and jaw significantly overlap the lower jaw and teeth.
  • Class 3: Class 3 crooked teeth is also diagnosed when there’s a severe underbite. This condition, also known as prognathism, means that the lower jaw protrudes forward. This causes the lower teeth to overlap the upper teeth and jaw.

  • Braces to correct the position of the teeth
  • Removal of teeth to correct overcrowding
  • Reshaping, bonding, or capping of teeth
  • Surgery to reshape or shorten the jaw
  • Wires or plates to stabilize the jaw bone

Lifestyle changes & Home remedies

What are some lifestyle changes or home remedies that can help me manage crooked teeth?
