Overbite Before and After

What is an overbite?

An overbite happens when the upper front teeth overlap the lower front teeth too much. Invisalign, a popular treatment, can discreetly and comfortably fix overbites by using clear aligners to gradually move the teeth into their proper positions, giving you a more aligned bite and a confident smile without the need for traditional braces.

What causes an overbite?

It is usually caused by the top and bottom jaws being different sizes. It can also be caused due to missing teeth in the lower jaw which causes the lower jaw to be smaller and a mis-match in jaw size.

Why Do I Have An Overbite?

  • Family Trait - Sometimes, the way our teeth come together is passed down through families. So, if your parents, siblings or grandparents had an overbite, there's a chance you might have one too. It's like how you might inherit the color of your eyes or the shape of your nose.
  • Childhood Habits - Things you did as a kid can affect your teeth. If you sucked your thumb or used a dummy for a long time, it might have influenced the way your teeth grew. Just like how playing a musical instrument can shape the way your fingers move, these habits can shape how your teeth come together.
  • Jaw Size - Sometimes, due to size and shape of the jaws, they don't fit perfectly together. It could be because your jaw is a bit bigger or smaller than it should be, or maybe your teeth are a little out of line. These differences in size and position can cause your upper and lower teeth to overlap, creating an overbite.

Aesthetic Concerns

  • The overbite that is noticeable can affect self confidence and self esteem, particularly with social interactions.

  • Speech - In some cases, overbites can contribute to speech difficulties, affecting pronunciation and clarity.

Oral Health

  • Tooth Decay Risk - Overlapping teeth can create tight spaces that are difficult to clean, increasing the risk of plaque buildup and tooth decay.

  • Tooth wear / Chipping and breaking - having a large overbite can result in an increased risk of tooth wear, in addition to increased risk of damage to the teeth by breaking them or chipping.

Got my Invisalign and whitening with dr Kunal at the Fleet Street branch and it really has been life changing. He’s given me the confidence to smile and laugh without covering my mouth. Very professional and listens to what i wanted and always exceeded my expectations. Also makes the entire Invisalign journey easy and comfortable as he was always there to answer any questions I had at any time. Highly recommend ruh dental and dr Kunal. It really is the best decision I’ve made. Had so many compliments on my teeth, even by strangers.

I couldn’t be happier with my experience at Ruh Dental. The staff are all really friendly and helpful, and every step of the treatment was clearly explained with no sales pressure at any time. My dentist was amazing and I’m so pleased with the outcome.

Overbite or Overjet

The term overbite technically refers to the vertical overlap between the top and bottom teeth. Someone with a deep bite would be considered to have a large overbite. This page refers to the term “overbite” from the view of a patient who is concerned with the horizontal overlap between the top and bottom teeth (“buck teeth” or flared teeth).

The correct orthodontic term here would in fact be overjet, or excessive overjet. We refer to the term overbite as this is what we find most patients actually attend saying they want corrected, which will make this page more informatively valuable for patients with this problem as the term overjet is unlikely to be something they are aware of.
