Can Braces Cause Gummy Smile or Make It Worse?

You’re at the end of your orthodontic treatment and you’re noticing that your smile doesn’t look the same in photographs. Your teeth are beautifully straight, but what’s the deal with that gummy smile? It didn’t seem to be there before braces.

Gummy smile is naturally occurring in many patients, but it can be worsened and even caused by braces during certain types of orthodontic movements – particularly retraction and extrusion. But just as they can cause gummy smile, braces can also correct it.

So, before you avoid belly laughing for your entire life, let’s explore this further and answer a few questions – did you have a gummy smile before, did you just now notice it, or could gingivitis be the culprit? Read on if you want to learn more.

What is gummy smile?

Gummy smile, medically known as “excessive gingival display“, is when you smile and there’s a disproportionate amount of gum showing.

Patients are often self-conscious about this and have developed a “social smile” that helps them hide their perceived imperfection – much like a selfie posture. It’s only during true, genuine laughs, that this gummy smile reveals itself in all its glory.

So it’s safe to say that capturing the true extent of a gummy smile in a photograph at the orthodontist’s office is sometimes a difficult task. However, it’s still something we need to measure because we need to compare progress and see if we can reduce the gum display.

What causes a natural gummy smile?

A gummy smile is not a medical condition that needs to be treated, necessarily – it’s just an individual trait. We’ve all seen people with gummy smiles and there’s no harm in having one.

But when excessive maxilla growth starts to interfere with eating, speaking, and stands in the way of a normal bite, it’s time to intervene.

Here’s what we notice in patients with naturally-occurring gummy smiles:

  • Excessive downward growth or downward tilting of the maxilla. Gummy smile isn’t limited to gums. Those gums sit on bone, and in this case, the entire bone is displaced downward inside the face. Some patients will have long faces and some will not be able to close their lips properly. When it’s severe, this type of anomaly can only be corrected through maxillofacial surgery.
  • Short upper lip. A short upper lip is just what the name suggests – short. If the teeth and jaws are otherwise healthy and normal, you can’t do much but make your peace with it.
  • Active upper lip. Hyperactivity in the lip muscle can cause it to contract and reveal too much of the gums. This is also an individual trait, so if it bothers you, you have the option of botox injections to help the lip stay lower during a smile.

How can braces cause or worsen gummy smile?

Let’s assume you had a moderate gum display before getting braces, but now your gummy smile seems much more obvious. What actually happened?

Well, it could be a number of things, and we’ll explore them below.

1. Crowding correction

If you had canines placed high up in the gums, or other misaligned teeth placed more vertically, their correction might confuse you. You may see gum exposure when, before, you barely had any gum showing at all.

2. Teeth retraction mechanics

During an extraction case, the upper front teeth are retracted towards the back with the use of powerchains, closing coils or archwire loops, and rubber bands. These forces can lead the occlusion plane downward and lead to more gingival display if no extra measures are taken to avoid this.
Correcting dental protrusion through extractions can lead to a certain degree of gum exposure, and the patient needs to be informed about this.

3. Open bite dentoalveolar correction

Patients with an open bite who refuse maxillofacial surgery can have their bite corrected through the use of up-and-down elastics and/or extractions. Since it’s only a dental correction, and the underlying, skeletal cause isn’t addressed, there’s a risk for the gummy smile to increase. But this is to be expected, and patients are often informed about this.

4. Gums growing over braces

Gingivitis associated with wearing braces is common, and will not completely go away until the braces are removed. It often takes months for the swelling to go down and the gums to recover. The teeth will appear smaller in size and the gums will look puffy and enlarged, giving the impression of a gummy smile. The solution is as simple as cutting the excess gum off – a procedure performed by an oral surgeon or periodontist.

Is there a way to fix gummy smile?

It’s important that you express your expectations before and during orthodontic treatment. If you see more gingival display developing, talk to your orthodontist before taking your braces off. Gummy smile isn’t an issue unless it bothers the patient, so we don’t always aim to correct it.

Here are the three main ways we can reduce your gummy smile inside the dental office:

1. TAD-supported intrusion

TADs (Temporary Anchorage Devices) are a wonderful new invention in orthodontics. These miniscrews act like anchors inside the bone, and we can achieve many new movements that may have been difficult or impossible before. Intrusion means driving a tooth into the bone – in our case, lifting the upper teeth toward the lip. We can lift the front teeth only or the front and back teeth (but that requires a lot more TADs). We can lift symmetrically (right and left), or asymmetrically if the bite plane is tilted.
After TAD-supported intrusion, gum surgery may be necessary to elongate teeth as they may appear a little shorter.

2. Maxillofacial surgery

Addressing the skeletal cause of gummy smile is the best way to go but this solution is often rejected by patients, especially in mild cases. Maxillofacial surgery is a serious intervention that’s expensive and requires time off from any activities. It’s also coupled with a lengthy orthodontic treatment with braces or aligners.

3. Gummy smile surgery

This type of surgery is performed on the gums alone, and it’s not as scary as it sounds. The periodontist or surgeon will remove as much unattached gingiva as possible in a process called “crown lengthening.” When everything heals, you’ll not only show less gum, but your teeth will also appear larger and more defined. Gummy smile surgery is performed for aesthetic reasons.

Something to consider before requesting gummy smile correction: A certain degree of gum display is normal, and maintains a youthful appearance. As a person ages, their upper lip tends to drop as a result of gravity, covering parts of the teeth. So if you don’t like your gummy smile in your twenties, you’ll be grateful for it in your forties and fifties.


A gummy smile can be charming or it can seriously hinder your self-confidence – it all depends on how you look at it. As orthodontists, we have tools that can reduce gum display, but uncontrolled forces can also lead to undesirable results. Talk to your doctor often about what’s bothering you – nothing is permanent until the braces come off!

Whether you’re new to braces or a braces veteran, taking care of your teeth and gums during orthodontic treatment is crucial. That’s why I’ve put together a list of orthodontist-recommended tools that will make caring for your braces a breeze:

  • An awesome mid-range electric toothbrush. Rotating electric brushes are much more effective, in my opinion, than sonic ones. You can keep your teeth white by using whitening replacement heads.
  • A countertop water flosser to blast out food debris between teeth. I know handheld models are tempting, but you’ll need a lot of water. You can almost replace flossing with this and your gums will be healthier.
  • Braces accessories to get into all the nooks and crannies: straight or angled interdental brushes, floss threaders, orthodontic wax or silicone. For pain management, have gel ice packs handy, Orajel, and Mouth Magic (a cool soothing solution for mouth sores).
  • For clear aligner patients, a tool like PUL helps both remove and seat your aligner or retainer. Don’t forget to use a cleaning product like crystals to keep your trays fresh and hygienic.

    It’s almost time for my braces to come off and after all this time last month my gums start showing when I laugh! I don’t like it and I asked my Orthodontist today and I felt as if she really didn’t have much to say! Her response! It’s ok you have a pretty smile and it will adjust. I have had a band at the top for 6 months because my teeth start gapping in the middle. I have a feeling that the band should have came off.

    I’m very concerned! I did get braces to gain another problem.

    Do you have any suggestions

    1. Adriana Sim, DMD Orthodontist says:

      Hi Tasha, it’s normal for your gumline to change with braces, and if it only shows a little more, then it’s okay. As we get older, our top lips tend to go down, and a slightly gummy smile is more youthful. If you hate your gummy smile, there’s not much to do at this point, but spend a lot more time in braces to correct it.
      As for the band (I assume you’re refering to powerchains), it usually comes off toward the end of the treatment, and if the gaps are still closed, they’ll stay that way if you wear a retainer. Powerchains are very strong and it’s not a good thing to keep them on all the time!
      Thanks for reading my article!

  2. Hi i had braces but now my teeth looks weired my teeth r not showing much gums show more nd my lower teeth tiled inside.there is no any problem of this gummy smile or tilled teeth before i had braces em so stressed how it can fix

      You could benefit from gummy smile surgery to make your teeth look bigger, and perhaps some bonding to change the shape of some of your teeth, but it’s best to consult with a cosmetic dentist.
