How Missing Teeth Affect Your Face

According to the American College of Prosthodontists, more than 120 million people in the United States are missing at least one tooth. Missing teeth pose a number of problems besides just looking bad. 

It might be harder to eat or speak clearly with a missing tooth. The space where a tooth once was can be a place where bacteria collect. This can cause gum disease or decay in neighboring teeth. People with missing upper teeth might also suffer from sinus problems.

Those are good reasons not to ignore the situation. But did you know that missing teeth can affect your face? Yes, they can actually change your facial bone structure… And the longer you wait to fix the problem, the more likely it is to affect the shape of your face. 

What’s the Big Deal About Losing a Tooth?

A missing front tooth changes the way you look in an obvious way. When you smile, everyone will see the gap. But there’s a lot more going on with teeth and the shape of your face. Teeth help to stabilize the jaw and surrounding bones that give your face its structure.

Front teeth offer support to the facial muscles in the lips and cheeks. Molars help maintain the shape of the jawline. Losing that support can make the face sag and droop. Cheeks will look hollow.

The teeth also support each other. When one or more are gone, there’s nothing holding neighboring teeth in place. The teeth will shift around and become misaligned. This can give the face an asymmetrical or lopsided look.

The most serious face-changing result of missing teeth is potential bone loss. A jawbone without teeth will begin to deteriorate and shrink. This is a major concern for a person’s dental and physical health, and can drastically change their face.

Dental restorations like dental implants, bridges, and dentures can fix the problems caused by missing teeth, but it’s important to act quickly before the changes become permanent.

Missing Teeth and Bone Loss

To understand why missing teeth are a serious matter, it’s helpful to know a bit about bones. We tend to forget that bone is living tissue. It’s capable of growing and healing, like when we have a broken bone or when the jaw bone grows around a dental implant post. Bones can also shrink. This happens as we age, but can also occur when teeth are missing.

Bones need stimulation to maintain their density. Both the top and bottom jawbone are stimulated by the tooth roots every time we chew. Losing a tooth means losing that root movement. The bone matter in that spot will start to break down and shrink. It will lose its shape and strength. 

Alveolar bone is the type of bone that’s in direct contact with the teeth and holds them in place. It is slightly softer than basal bone, which makes up most of the jawbone. The alveolar bone is affected first when a tooth is missing and will start to lose mass, a process called resorption. Eventually, the basal bone beneath it can shrink too. There is a danger of losing even more teeth when the jawbone is weakened. Greater susceptibility to fractures is a possibility too.

The upper jaw, called the maxilla, is attached to the eye sockets and nose. The chin is part of the mandible or lower jaw. A deteriorating jaw won’t be able to support these other areas, adding to a sagging and sunken look across the entire face.

Resorption of the jawbones is the reason why facial features will look different. Luckily, the process can often be stopped or reversed by dental restorations like dental implants and bone grafts. But it’s important to act fast to fix missing teeth before too much bone disappears.

What You Could Look Like With Missing Teeth

Losing even one tooth can change the face in certain ways depending on its location in the mouth. Losing several will only make the problem worse. These are some specific features you may notice:

Asymmetry

When a tooth is gone, there’s nothing to hold the other teeth in place. They will start to drift out of alignment. This can cause an exaggerated underbite, overbite, or crossbite, depending on where the missing tooth was.

The teeth won’t meet in the proper way and in the right spots anymore. Over time, as you continue to chew and talk, your jaw will move too. Instead of coming together in a straight line when you bite down, the jaw bones will meet on an angle. The face will look off-kilter and lopsided, with one side of the jaw higher than the other.

Sunken Cheeks

Lost molars leave an empty space where the sides of the mouth can cave in and look hollow. This is especially true when the top molars are missing. As time goes on, bone loss will make the sagging look even more pronounced, resulting in a gaunt appearance. 

Compressed Jaw

Molars are responsible for maintaining the height of your face. As bone mass is lost from missing teeth, the jawbone gets smaller. With diminished jawbones, the entire bottom part of the face will look shorter and squished together. The bottom jaw can also rotate forward as it shrinks, creating a receding chin and collapsed look.

Permanent Frown

Without front teeth to support the muscles around the lips, the shape of the lips and mouth can change. The muscles will slacken and causing the corners of the mouth to turn down into a frown. This can also cause sagging and wrinkles and make a person look older. 

Reversing the Effect of Missing Teeth on Your Face

The good news is there’s a way to stop and even reverse the way missing teeth affect your facial features. Implants, bridges, and dentures can all help to fill out the empty spaces.

Dental implants, in particular, can do the most to support and stabilize the rest of the teeth and jaw, so that the face can regain its appearance. Filling in the gap with an artificial crown is only part of the process. When a dental implant is put into the jawbone, the bone grows to surround and fuse to the post. Implant surgery actually helps to regenerate healthy bone tissue and rebuild the jaw—which, in turn, will fill out the shape of the face.

Waiting too long to fix a missing tooth allows the bone to start resorption. If the jaw is too weak or has shrunken too much, bone grafts might be needed to prepare the site for an implant. This will give the jaw some structure for the post to anchor to. If too much time has passed and the bones are too far gone, dentures may be the only option. The quicker a lost tooth is restored, the better.
