The Different Types of Crooked Teeth

There are different types of teeth misalignment and they are not all mutually exclusive. Here is our guide to the types of crooked teeth.

Having crooked teeth, or misalignment of teeth and bite can get in the way of that smile you deserve. There are different types of teeth misalignment and they are not all mutually exclusive. Here is become’s guide to the types of crooked teeth (or the official term used by orthodontist: malocclusion).

1. Overcrowding

When teeth have insufficient room to erupt from the gum, overcrowding occurs. This is common for teenagers when the permanent teeth set – which has 12 more teeth than in the baby set – don’t have enough space in the mouth to grow in straight. Overly crowded teeth are hard to clean, leading to plaque accumulation, tooth decay and an increased chance of gum disease. 

2. Overjet

Overjet teeth are also known as upper front teeth protrusion or buck teeth. Not to be confused with an overbite, overjet is where your top teeth extend past your bottom teeth horizontally. This makes the upper teeth prone to accidental breakage, and hard to comfortably close the mouth completely.

3. Overbite

When the bite is too deep the upper front teeth cover the lower front teeth too much, it’s called an overbite. Overbites are most common in children, and sometimes cause the lower front teeth to bite into the roof of the mouth.

4. Crossbite

  • An anterior crossbite, or underbite is characterized by the lower jaw extending out, causing the lower front teeth to sit in front of the upper front teeth. 
  • A unilateral posterior crossbite, typically referred to as a crossbite, is what occurs when your upper teeth, usually the back teeth, fall inside your lower teeth you bite down.

These can cause excessive tooth wear and jaw stress. Other effects include eating and chewing difficulties, headaches, tooth decay, chronic mouth breathing, and speech issues.

5. Spacing & diastema

Spacing problems may be caused by missing teeth, a tongue thrust habit or periodontal disease. Spacing can occur between two or more teeth, and diastema is the term to describe space between two teeth. The problem with spacing is that food can get stuck in between teeth, which can lead to cavities and gum disease. 

6. Open bite

When the upper and lower front teeth do not overlap, it’s called an open bite. There are two types of open bites:

  1. Anterior open bites – An open bite affecting only the front teeth.
  2. Posterior open bites  – When the front teeth meet but the back teeth do not.

In extreme cases, open bites can cause problems swallowing, tongue thrusting, and some speech problems

Thankfully, nowadays there are alternatives to managing misaligned teeth without having a mouth full of metal. At-home invisible braces (or teeth aligners) is one of the most affordable options.
