What exactly is an underbite?


An underbite is whenever your lower front teeth sit in front of the upper teeth when you close your mouth. This is the opposite of how your front teeth are supposed to sit. Ideally, your top front teeth are supposed to sit in front of your lower ones. With an underbite, this relationship is reversed. Most underbite cases are the result of your lower jaw being too large or otherwise positioned too far out forward.

It's important to try and fix your underbite whenever it's possible. Having an underbite can be very harmful to the long-term health of your front teeth. The incorrect tooth relationship places lots of added stress onto your front teeth. As a result, you're much more likely to chip, fracture and wear out your front teeth as you age. Fixing your underbite protects your front teeth by reducing the stress on them. This helps protect you front teeth and keeps them happy and healthy.

Can you fix your underbite with clear aligners?

Unfortunately, clear aligners are rarely used to fix underbites. To fix your underbite, you need to wear require braces. In fact, more advanced underbite cases require additional treatment including tooth extraction, face gear or even jaw surgery! Of course, there are some occasional underbite cases which do end up qualifying for clear aligner therapy. For an underbite to qualify for clear aligners, the following conditions must be met:

  • Your jaw relationship must be correct. If there are any discrepancies between your upper and lower jaws then clear aligners are not going to work for you.
  • Your underbite needs to be limited to no more than a millimeter or two. This means that your lower front teeth are just barely in front of the upper ones. Anything more than this does not qualify for clear aligners and requires braces instead.

If an underbite qualifies for clear aligner therapy, it must be treated under direct dentist supervision. You should never rely on at home clear aligners to fix your underbite. Unsupervised aligner treatments like Smile Direct Clubcould damage your front teeth or mess up your bite. Choose Invisalign® or Even28 at-dentist™ to fix any underbite condition that qualifies for clear aligner treatment.
