Overbites vs. Underbites: What They Are and How Invisalign Can Help
Overbites and underbites are two common forms of misaligned teeth. We’ll go into more detail below, but here are some simple definitions:
- An overbite is when your upper front teeth extend beyond the lower front teeth.
- An underbite is when your lower teeth protrude past the upper front teeth.
All about Overbite Teeth
Minor overbites, when upper teeth extend slightly over lower teeth, are common and not necessarily a concern that needs fixing. However, when your overbite teeth extend past the bottom teeth by as much as 4–10 millimeters, the issue becomes more pronounced. Some causes for this common Class II bite can be:- Genetics
- Thumb sucking
- Gum disease
- A recessive chin
- Poorly fitted crowns
- Accident or injury
All about Underbite Teeth
A Class III bite, called an underbite, happens when your underbite teeth extend beyond the upper teeth. This is less common and tends to be more serious than overbites. This is because when the lower jaw protrudes, the lower row of teeth cannot align with the upper row. A host of serious oral health issues can result. Causes include:- Genetics
- Childhood habits
- Accidents
- An underdeveloped upper jaw
- Overdeveloped lower jaw
Get Invisalign to Treat Over- and Underbites
Many patients choose to correct their overbites and underbites with traditional metal braces. However, for some patients, Invisalign is a better option. This is because Invisalign—or clear plates and aligners rather than metal brackets and wires—are:- Discreet. Since they’re clear, Invisalign aren’t as easy to see as metal braces.
- Conducive to good oral health. For example, you can remove them whenever you need to brush or floss your teeth.
- Convenient. The trays can be removed for up to two hours each day, which makes eating and drinking easier than with metal braces.
