An underbite is a condition where your lower teeth jut out further than your upper teeth. You may also hear your orthodontist call it a Class III malocclusion.
A crossbite often presents during childhood and does not correct itself as the child gets older. There are different kinds of crossbites and they can affect both the front and back teeth, posing possible health risks.
A deep bite, also known as increased overbite, is the most common malocclusion found in both children and adults. While many may consider a deep bite nothing more than a cosmetic factor affecting a smile, a deep bite is much more than that, and, if left untreated, can result in many different dental, jaw, and facial complications.
