Sunken cheeks with braces is a condition that many people encounter. This condition affects the health and aesthetics of people with braces. So what is the cause and what ways are there to fix sunken cheeks when wearing braces? Let's find out with Lac Viet Intech Dental Clinic in the article below.

Causes of braces causing sunken cheeks:

Braces are a safe and effective method to correct malocclusion. Helps people with braces have beautiful teeth and an aesthetic smile. However, There are many cases where customers encounter this situationBraces cause sunken cheeks. So what is the cause?

First: The doctor has poor skills and gives an incorrect treatment plan

Doctor's skills greatly determine the success or failure of a braces case. 

A highly skilled and clinically experienced doctor will give extremely precise instructions for tooth extraction. Because if tooth extraction is indicated in the case of a patient with missing, unbalanced, unharmonious dental arches and insufficient support for the lips and cheeks, the cheek sagging will certainly not go away for a long time.

If the doctor is not very skilled, during the orthodontic process, there will be operations that are not gentle, causing pain and discomfort, leading to hindering the patient's chewing process. When experiencing discomfort during braces, the patient will chew poorly. This leads to sunken cheeks and sunken temples.

Whenbrace, the doctor needs to accurately calculate the force that moves the teeth. If you do not have enough clinical experience, it is very easy for the doctor to apply the wrong force, causing the tooth root to move incorrectly. This leads to misaligned teeth, tilted teeth, difficulty chewing, or even a completely misaligned bite. At that time, the face not only has sunken cheeks but is also unbalanced.

Second: Orthodontic appliances do not guarantee quality

A set of orthodontic appliances for external braces will include 3 main systems: Braces, arch wire system and passive or active power generation system. If the treatment process is to be successful, all three systems above must be good. Just 1 in 3 of poor quality will cause unnecessary complications during the braces process.

If the dental facility you treat uses poor quality braces, when the doctor adjusts the force to increase or decrease it will affect the arch wire. If the tightening force is too strong, the tooth root cannot withstand the impact, causing the tooth root socket to collapse, causing the tooth to loosen and even lead to tooth loss. At the location of tooth loss, the cheeks will be sunken. 

Third: Asymmetry of muscle activity or reduced muscle activity due to chewing habits with braces

The habit of chewing on one side seems harmless but leads to the muscles on one side developing more than the other side, which can lead to an asymmetrical face. When this condition persists, it will affect the movement of the temporomandibular joint. Because the larger the muscle, the greater the muscle contraction force will be, causing pain and joint sounds if not adjusted and treated promptly.

The temporalis and masseter muscles are two very large muscles that play an important role in chewing and supporting the cheeks and temples. In people without braces, normal chewing leads to these two muscles being very large and strong. It will fill the temporal pits and fill the cheeks. Therefore, we cannot see the sunken temples or sunken cheeks or face at all. 

However, in people with braces, with a system of appliances in the mouth that makes chewing difficult, you will prioritize eating soft foods, eat less than usual and talk less. At that time, the temporal and masseter muscle systems are less trained, so they will develop less and atrophy, leading to the skin being sunken in, causing sunken cheeks and sunken temples in the early stages of braces. Just like gym goers, when they exercise regularly and regularly, their muscles grow very strong. However, if we do not practice for a while, we can see a complete change. 

That's why, usually after installing braces, Lac Viet Intech Dentist will carefully instruct patients that right after getting used to braces (maximum 1 month), you need to practice chewing regularly on both sides, practice eating hard foods gradually so that the muscles are activated and work regularly, thereby firming up again to support and fill the cheeks.

Fourth: The alveolar bone is resorbed or loses its anchor. block

Often in cases of protruding teeth, crooked teeth, etc., the doctor will prescribe tooth extraction to create space for the teeth to move. However, if the treatment is prescribed incorrectly and the tooth extraction space is not closed tightly, it will lead to the alveolar bone in that area being lost, causing sunken cheeks.

On the other hand, in cases where the extraction space is closed but due to loss of anchorage, the posterior teeth move into the extraction space rather than pulling back the front teeth, causing the back muscles to lose support, which in turn is also the cause of cheek sagging during braces.

In some cases of braces with tooth extraction, the dental arch is shortened, reducing muscle attachment points, leading to a temporary decrease in muscle volume, also causing the cheeks to sagging.

Cheek sagging due to regime disorders. Eating and drinking

When you first get braces, you will feel a little sore and uncomfortable due to the braces rubbing against your cheeks and making you feel uncomfortable eating and drinking. Besides, due to the fear of your braces falling off, you will limit your intake of hard foods, leading to nutritional deficiencies and weight loss. When you lose weight, your cheeks will feel sunken, especially for those with long faces and high cheekbones.

After time has adapted to wearing braces, you should get used to chewing normally again with a varied diet. Just be careful to cut food into small pieces to avoid using too much chewing force, causing the braces to fall off.

In addition, staying up late, stress, insomnia, stress,... also makes you susceptible to weight loss, a skinny face and sunken cheeks when wearing braces.

Do cheek-sagging braces last forever?

Cheek-sagging braces last forever?exists forever, the answer is: no. Sagging cheeks in the early stages of braces is very normal and you don't need to worry too much about this. The sunken cheeks will usually end when your diet is balanced again or at the latest after you remove the braces.  

In case braces require tooth extraction, if your doctor is highly qualified, he will come up with a methodical treatment plan and move the teeth according to the correct procedure. Thanks to that, after finishing orthodontics, the result you will receive is not only beautiful teeth but also a slim face, the chin angle is tapered to the V-line standard, not sunken cheeks.

Braces are considered a safe and sustainable beauty method because after braces, your bite is brought to standard and your face is balanced. Currently, many people want to create a v-line face by injecting Botox to reduce the masseter muscle and injecting chin filler. Although this method is effective immediately, the maintenance time only lasts 4-9 months. Meanwhile, for braces with tooth extraction method, muscle balance will create a naturally slim and long-lasting face. 

How to overcome sunken cheeks when wearing braces:

The condition of sunken cheeks greatly affects aesthetics, making people experiencing this condition feel less confident in communication and daily life. The following are ways to overcome sunken cheeks during braces:

Supplement adequate nutrients and diversify the menu

As mentioned above, lazy eating is the leading cause of common sunken cheeks. Therefore, to limit this situation, during the braces process you need to fully supplement nutrients from many different food groups. During the initial period of wearing braces, if you have difficulty chewing, you can divide your meals into small portions and eat soft, easy-to-chew foods.

After you get used to wearing braces (up to 1 month), you should eat a variety of foods. Foods that are hard and difficult to chew can be cut into small pieces and eaten slowly and chewed thoroughly. This causes your temple and cheek muscles to be developed and firm with regular exercise, helping to support and plump your cheeks and temples.

When you first wear braces, you often tend to be afraid to smile and hesitate to communicate. This leads to less flexible and less active facial muscles, which can also cause sunken cheeks and sunken temples. Talk comfortably and smile a lot because you will look very beautiful when you are confident!

Choose braces at a reputable dentist

Choosing a reputable dental address will help you avoid the risk of sunken cheeks when getting braces, why is that?

Modern braces technology 

Reputable dentistry will possess technologies that help support thebraces processto proceed smoothly. In medicine, diagnosis based on senses brings potential harm during treatment. Specifically in braces, with traditional methods, the doctor will mainly set the force according to the patient's experience and pain threshold. If the patient's pain level is unbearable, the doctor will reduce the force of tooth tightening. This causes pain during the orthodontic process.

Lac Viet Intech Dental is a pioneer dental unit that brings artificial intelligence into patient treatment planning, with the introduction of X-Matrix braces technology and the following outstanding advantages:

Double the effectiveness, shorten braces time

Applying orthodontic technology helps double orthodontic effectiveness compared to traditional orthodontic technologies. X-Matrix helps doctors create detailed and accurate treatment plans, calculate appropriate tooth tightening force, thereby helping to eliminate complications and shorten braces treatment time by ⅓. 

SmileStream software in X-Matrix helps personalize braces, supporting doctors in planning accurate treatment for each patient.Calculate exactly which teeth - how much force is most physiological to apply so that the patient does not experience pain but still achieves the effect of moving the teeth safely and quickly. When the braces process goes smoothly and gently, your chewing will not be affected. From there, sunken cheeks and sunken temples will not occur.

Plan precise treatment and personalize braces

Each person has a different bone and tooth structure, so different braces systems and tooth tightening forces will be needed.

Smile Stream's smart algorithm will automatically calculate the optimal moving force for each tooth and the most accurate bracket placement on the tooth crown. This helps doctors plan accurate treatment for each patient.

Design a standard smile

Not only does the X-matrix evenly align the teeth, it also moves the tooth complex and alveolar bone, thereby affecting the lip structure, nose angle, changing the width - narrowness of the dental arch, restructuring the face, shaping a standard smile for each face. Thanks to that, during the braces process, not only will the sunken cheeks be limited, but after removing the braces, the face will also be slimmer.

Painless braces

With traditional braces technology, doctors will not be able to accurately measure the bone density around the roots of the teeth, making the calculation of the force to move the teeth inappropriate. It will all be based on the doctor's experience and testing the patient's pain threshold. When the patient feels too much pain, the force will be reduced.

For X-Matrix technology, the force to move teeth will be accurately calculated by doctors based on the trio of Smile stream - Web Ceph - Auto Lign technologies, thereby limiting pain, discomfort and 99% of relapse after braces. 

Doctor of Lac Viet Intech Dental shared about X-Matrix braces technology on VTV2's Live Healthy Every Day talk show.

Compilation of exercises to overcome sunken cheeks when wearing braces

Functional exercise 1: Gum chewing exercise - improve chewing muscles

This exercise helps overcome lazy chewing and chewing on one side. You should do it 3 times a day, morning, noon and night. 

How to do it:Chew gum (use low-sugar candy to avoid causing tooth decay) for about 30 minutes each time. When chewing, rotate the candy from the left jaw to the right jaw and vice versa. Note: Absolutely do not chew with one jaw because this will be counterproductive.

While chewing, you can place your hand on your temple to feel muscle vibrations. Regularly performing chewing exercises will help exercise the temporal and masseter muscles, thereby developing firmness and plumping the cheeks and temples. 

Functional exercise 2: Mewing muscle exercise

This exercise is effective for people who have the habit of pushing their tongue, breathing through their mouth,... not only to help the face harmonize but also to support the braces process to go smoothly.

How to do it: 

Step 1: Keep your head straight. People with the habit of mouth breathing often tend to put their heads forward to expand airway volume, the bridge of the nose is often low, and the jawline is short and unclear. 

Step 2: Place your tongue on the palate in the gum area between the two front teeth and be careful not to touch the teeth. To practice the exercise of placing your tongue in the correct position, you can open your mouth and pronounce the letter "N" and then hold your tongue in that position, making sure your tongue does not touch your teeth. 

At first, when you first do it, you may feel tired because you have been used to the wrong tongue position for a long time. But keep practicing because the results will not disappoint you.

Note: Absolutely do not breathe through your mouth, you need to breathe evenly through your nose during exercise.

This method has been proven to be effective in improving side angles and reshaping a balanced face.

Functional exercise number 3: Practice laughing loudly and not closing your eyes.

This is an exercise that helps train the function of the temporalis and masseter muscles. Actually, when you have braces, you are very shy to smile and communicate. This causes the temporalis and masseter muscles to not work regularly, causing the cheeks to often sink in. Regularly practicing opening your mouth wide and smiling without closing your eyes is like a gym exercise to help strengthen the muscles to support the cheeks better.

How to do it:

Slowly open your mouth as wide as possible, after filling it with air to make your cheeks bulge, then slowly close your mouth. Repeat this movement about 20 times and do it several times a day to achieve good results. 

Another way is to smile all the way to the side without closing your eyes. Do this continuously and regularly until your facial muscles are comfortably stretched.
