It can also be caused by trauma (such as chipped or broken tooth), gum diseases as well as gingivitis. If ignored tooth dental abscess can cause an opening in enamels that will make bacteria go to the tooth pulp and spread to the tooth root and jaw bone i.e. swollen jaw from abscessed tooth.

Where does it occur 

You can expect swelling anywhere on your cheek, both the inside or outside. Let us look at a little more on where it can occur. 

1. Inside cheek and mouth

Sometimes, it can happen on your inner cheeks. This can be caused by most of the causes we have already mentioned such as tooth problems (decay and infection), canker sores, swollen salivary glands, mouth sores, biting, trauma, infections (bacterial or viral), tooth abscess, lymph node problems (especially the preauricular, submandibular lymph nodes and tonsilar), mumps, among other causes.

Furthermore, various procedures such as tooth feeling, oral surgery, tooth extraction, piercing, among others can also result in swollen cheek inside mouth especially the surrounding tissue.

This problem can affect children (toddlers or babies) as well as adults and it can make the cheeks numb, extend to your jaws, or be near your wisdom teeth (in case of wisdom tooth extraction or infections). Treatment will depend on the underlying cause.

2. Swollen gums too 

Swollen gums and cheek could be due to any of the causes mentioned such as infected tooth (tooth abscess or tooth decay), tooth extraction (especially wisdom tooth), after a root canal, blunt trauma, oral cancer, etc.

Furthermore, it can be due to gum problems especially gingivitis, teething syndrome, herpes stomatitis, parulis, periodontal disease, malnutrition, badly fitting dentures, as well as other viral or fungal infections. Pericoronitis (a dental disorder that makes gum tissue around wisdom teeth, to be swollen) has been found to result in swellings.

The swelling between cheek and gum could cause a numbing feeling, be sore and make chewing painful and difficult. To reduce distention from gum infection, try sucking ice (cold compress), use over the counter anti-inflammatory medication, swishing sea salt and water mixture as well as treat the underlying cause (disease or condition). 

3. Cheek and jaw swelling 

When the swelling extends to your jaws, including jawline or neck area can be caused by any of the causes we have already discussed. It could be accompanied by pain or no pain or cause numbness depending on the underlying cause.

4. Swollen eyes and cheek area

Sometimes the distention can be accompanied with swollen eyes i.e. either right or left side and swollen under eyes or eyelids especially if caused by allergies. However, eye problems such as swollen eyes can also cause swelling on cheeks.  Ensure you get the right diagnosis.

In babies 

In children, this problem can be due to bone fracture, allergic reaction, infection, infected salivary glands, tooth abscess, after teeth filling,  some gum infections, mumps among other infections. The swelling might make cheeks red, cause tooth pain, and it could also extend to the jaws and neck depending on the cause.

Swollen with no pain

Not all edemas are accompanied by pain always. It is normal to have a swelling with no pain or with mild or slight pain. Sometimes, cysts, dental abscess, allergic reactions, swelling due to malnutrition, etc. might not cause any pain.

However, in some instances, the distention is accompanied by some pain (red inflamed and swollen cases). In such a case, you need to go for the over the counter anti-inflammatory drugs as well as apply cold compresses to reduce inflammation and swelling.


Treatment option will depend on the underlying cause. In case you do not know it, you should seek medical attention for diagnosis and prescription of the right medications. Common treatments for swelling of cheeks include:

For mild swelling caused by trauma such as dental work (root canal, tooth extraction, teeth filling, rhinoplasty, oral surgery, piercing, blunt trauma, etc.), you can apply warm or cold compresses.

For a cold compress, the use of ice or cold compress will also cause a numbing effect that will alleviate pain and discomfort. Do not apply ice directly, wrap it in a piece of clean cloth or buy ice packs to avoid tissue damage. Let the compress remain in place for 20 minutes.

2. Applying potato slices
