The Jorgensen Orthodontics Blog

Why does my orthodontist only want to remove two teeth in the upper arch?

Posted by Dr. Jorgensen on July 23rd, 2013

Overbite girlThe articles that attract the most comments on my blog are those addressing the removal of permanent teeth (also called pulling or extracting teeth). I sympathize with parents and patients who are worried about having perfectly healthy teeth extracted for orthodontic purposes. The explanations I’ve provided in other articles have helped many patients to understand why this can’t be avoided in many cases (see Are There Alternatives to Having Teeth Removed for Orthodontic Treatment?, Will Having Teeth Removed Ruin My Face?, and Why Do I Need Teeth Removed for My Braces?). Today’s blog post addresses a specific extraction pattern that I’ve been asked about numerous times: removing two teeth in the upper arch only.

There are three main reasons that I remove permanent teeth during orthodontic treatment: crowding, protrusion, and camouflage of a jaw-size discrepancy. As much as I would like to avoid removing teeth, there are some mouths that are just too small for all of the teeth. In these cases, NOT pulling teeth makes the smile less attractive, less healthy, and less stable. Protrusive teeth are just crowded teeth that have been flared out away from the bone. If they were to be moved back over the bone where they should be (without removing any), they would overlap (be crowded). To relieve crowding and protrusion I sometimes need for your dentist to remove some permanent teeth. The space created is then closed to eliminate the crowding or reduce the protrusion. Done correctly, no one but you and your dental team will ever know that you’ve had teeth removed.

When the upper and lower jaws are genetically different sizes, the only way to truly make them match is surgical repositioning (orthognathic surgery). Surgery is required when patients have a severe discrepancy or want a specific cosmetic improvement (i.e. a bigger chin). Most patients however are fine with just having their “overbite” corrected without the surgery if the final result is attractive, healthy, and stable. Removing teeth in only one arch is the most common way to camouflage a jaw-size discrepancy. About two-thirds of my patients have an overbite. Mild to moderate overbites can be corrected with rubber bands or springs. In those with more moderate to severe problems, extracting teeth or surgically moving the jaws is necessary.

If a patient has a small lower jaw, removing two teeth in the upper arch allows the orthodontist to move the upper front teeth back to match the position of the lower teeth without surgery. This allows us to hide or camouflage your small lower jaw. The same thing can be done in some underbites. If conditions are just right, two teeth may be removed from the lower arch to allow the lower front teeth to be moved backwards correcting the underbite. If teeth were removed in both the upper and lower arches in overbite and underbite patients, the upper and lower front teeth would move together and no improvement would be accomplished. Please understand there are many variables that your orthodontist must take into account when determining if camouflage treatment is appropriate for you. This explanation is an over simplification, but you get the idea.

So if your orthodontist suggests removing teeth from only your upper or lower arch, chances are that you have a jaw-size discrepancy that he is trying to improve for you. I’ve been using this extraction pattern for over 20 years and in the right patients the results are amazing. Remember to ask your orthodontist about any extraction pattern that doesn’t make sense to you. The best patients are the most informed patients.

    My sister had an orthodontic treatment in which her two premolar upper teeth were extracted to make the space (as she had overcrowded teeth in the upper jaw line, the lower one has no overcrowding)…As per doctor’s suggestion, her two premolars from lower jawwline shall also be removed in order to have a proper matching jawline and teeth cycle. I am confused bcoz if the lower jawline is fine, not at all overcrowded, then is ‘tooth extraction’ becomes mandatory to maintain teeth cycle that my doctor talked about..pls guide.. I mean is it important to remove the premolars from lower jawline if not required..

    • If your sister has jaws that are the same size and the bite is good, four teeth should be removed. If she has an overbite and the lower jaw is small, it is usually preferable to not remove bottom teeth. There are exceptions, but removing four teeth when their is an overbite makes correction much more difficult.

    Hi I went to two orthodontists and they both said completely different things when it came to teeth extractions. The first one said they only wanted to remove one tooth from my upper jaw and the other wanted to remove four (two top, two bottom). Is it a common practice to just remove one tooth?

    • It is much more common to remove four than one. I would present both treatment options to each orthodontist and have them explain why their plan is different. Choose the one that makes the most sense (and make sure they are both equally educated and have the same experience).

    My son does not have permanent adult teeth K, T. His orthodontist originally suggested to remove baby teeth A, J, K, T, and remove adult A, J teeth when they come out, but he now suggested to remove 4 baby teeth and adjacent adult teeth 5 and 12 to make extraction all at once. This means in the future, his adult A,J teeth will touch bottom adult teeth 28 and 21. Will it cause problem on biting? Thanks Dr Jorgensen.

    • There are as many successful treatment plans as there are kids. It sounds like your orthodontist has a plan. Make sure it makes sense to you and work together on the plan so that it will work out in the end. Remember that your son already has a compromised situation because of the missing teeth. The goal is to find the best solution for him.
