Asymmetrical Jaw: An Overview

An asymmetrical jaw is uneven or misaligned, often due to genetics, TMJ disorders, or dental issues. No one has a perfectly symmetrical face, so it’s normal for your jaw to look a little different on each side. However, if your asymmetry is more pronounced, you can usually address it with medical or dental procedures.

An asymmetrical jaw looks slightly different on each side. No one’s face is perfectly symmetrical, so a certain degree of jaw asymmetry is completely normal. However, some people can have a more pronounced asymmetry of their jaw, leading to a more uneven or misaligned look. This may cause them to seek out medical or natural treatments to create a more symmetrical appearance.^{[1]

Genetics Some people are simply born with a more asymmetrical-looking jaw due to the bone structure they inherit from their parents. This is incredibly common, as no one’s face is perfectly symmetrical. In fact, perfect facial symmetry would appear slightly strange or uncanny to us, explains board-certified plastic surgeon Asif Pirani, MD.^{[3]

- “They've done psychological studies where they'll take the left side of someone's face and flip it so it's perfectly symmetrical, and when you show it to people, it actually looks abnormal,” Dr. Pirani says.^{[4]

Physical injury to the face can affect your jaw alignment, which can lead to a more asymmetrical appearance. For example, if you fracture your jaw as a result of a vehicle or sports accident, it could end up looking slightly more uneven or misaligned when it heals (though this isn’t always the case).^{[6]

One common culprit of an asymmetrical jaw is malocclusion, or a misaligned bite. This means your upper and lower teeth don’t fit together correctly when you close your mouth, which can be a result of overcrowded or crooked teeth. Malocclusion is typically hereditary (meaning you inherit it from your parents), but tooth loss or dental trauma are other possible factors.^{[9]

Dr. Pirani says the proper treatment for asymmetry will depend on what’s causing it, but a less invasive option like Botox may be an option. “If it’s muscular in nature, sometimes there are some things you can do with Botox, [like] weakening an overactive muscle on one side,” he explains.^{[12]

Dental work “A lot of people have skeletal malocclusions, and that's the reason why their faces are not symmetrical,” says cosmetic dentist Nidhi Pai, DDS. “We are looking at the jawline from the outside, but a lot of support comes from the teeth inside. Once the inside tooth structure is fixed, their bite is fixed. A lot of definition can come from there.”^{[15]

Jaw surgery Depending on the cause of your jaw asymmetry, surgery may be the best option. “If it's more structural, then usually you're going more towards surgery,” explains Dr. Pirani. “For example, if someone has an asymmetry of their jawbone, then sometimes you need orthognathic or oral maxillofacial surgery, and that can help improve things like that.”^{[18]

- Jaw surgery is an invasive procedure with a longer recovery time, so be sure to discuss this option in detail with your doctor if you’re considering it.
- Initial recovery often takes about 6 weeks, but your jaw will continue to heal over the course of several months. You’ll also need to stick with a soft diet for a period of time.^{[20]

Facial exercises According to Wayne, if your masseter muscles are way more developed on one side, this could make your jaw look more asymmetrical. In this case, Wayne recommends facial exercises targeting your masseter muscles. “You can do some masseter training [...] you can chew on mastic gum, or there's also jaw trainers. If you want to beef up the masseters a little bit, that could make them look more symmetrical.” He also says that practicing mewing may help.^{[21]

- However, Wayne warns not to go overboard. “You have to be careful about overtraining [your masseters] because any time the jaw is wider than the midface or the upper third, it kind of makes the face look overly masculine. You kind of look like a character from a video game, but not in a good way.”^{[22]

- It’s also important to remember that there isn’t strong scientific evidence to support the effectiveness of these types of facial exercises, especially if your asymmetry is the result of an untreated medical or dental issue.
- According to Dr. Pai, someone who is already pretty symmetrical may see some benefit from facial exercises, “But someone who has skeletal malformations—they can do the mewing all day long, and it's not going to benefit them. It might just cause a lot of muscle soreness.”^{[23]

If you wear makeup, you probably know that cosmetics can be very effective for creating a more symmetrical look. To even out an asymmetrical jaw, try applying a contour shade along the outer edge of the larger/wider side. This creates shadows and has a slimming effect, making this side look more similar to the smaller side.^{[24]

Asymmetrical Jaws: The Bottom Line

No one’s face is perfectly symmetrical, and having a slightly asymmetrical jaw is very common. However, if you have a more pronounced asymmetry that you want to address, your first step is to see a medical professional to figure out the underlying cause. Depending on the reason behind the asymmetry, fillers, Botox, dental treatments, or jaw surgery may be your best option. Some people believe facial exercises can help, but there hasn’t been enough scientific evidence to definitely support this.
