Swollen gums in the back of the mouth: an acceptable concern

Swollen gums can occur for several reasons, although in most cases, it can be a symptom of gum disease, such as inflammation or infection in the gum tissue. When this occurs in the back of the mouth, it can interfere with chewing, speaking, and overall oral hygiene. Therefore, it is important to identify the cause of swelling in order to find a suitable treatment and get rid of it.

Common causes of gum swelling at the back of the mouth

Several factors can lead to swollen gums, especially in the back of the mouth:


Poor oral hygiene

Improper oral hygiene is the root cause of swollen gums. When you brush and floss your teeth irrregularly, it leads to the accumulation of plaque and bacteria on the teeth, which can cause inflammation and swelling of your gums. Note that the back of the mouth is not easily accessible by a toothbrush, so if you are negligent in cleaning the back gums, you will have gum swelling in the back of the mouth.


Gum disease

Gum disease (gingivitis and periodontitis) is another common cause of gingivitis. This disease is actually a bacterial infection that have impact on the gums and the bones that support your teeth. A milder type of gum disease is gingivitis. which is featured by redness, swelling and bleeding. If this gum disease is not treated in time, it can turn into periodontitis, which affects the bone that supports the tooth. Gum illness can cause tooth loss and other serious health problems.


Issues related to wisdom teeth

One of the essential causes of gum swelling in the back of the mouth is wisdom teeth. which can cause considerable discomfort and swelling in the gums. These teeth often have problems in growing properly. Especially when all permanent teeth are healthy. Therefore, the wisdom tooth will not find a place to grow. And in trying to grow, it will lead to inflammation and infection.


Dental infections

The mouth, like any other part of the body, can get infected; An event that leads to gum swelling. For example, complications of chronic infections such as herpes may cause swelling in this area. Also, oral thrush (a type of fungal infection in the mouth) can also have symptoms such as gingivitis.

Dental abscess also causes similar conditions. Of course, swellings caused by abscess usually show themselves in a specific area.

 These infections are usually caused by untreated cavities or gum disease and require prompt dental intervention.


Food particles and debris

Yes, the cause of gingivitis can sometimes be as simple as this. For example, think about the last time you ate popcorn; maybe the hard pieces got stuck between your teeth. Food particles stuck between the teeth, especially in hard-to-reach areas such as the back of the mouth, can easily cause irritation and swelling.

Of course, this cause of gingivitis does not last long, and it goes away with brushing and flossing (correctly).


Allergy or sensitivity

Certain foods, dental products, or medications can cause allergic reactions or sensitivities that lead to swollen gums in the back of the mouth. For example, blood pressure medications can cause swelling of the gums as a side effect. It is better to know them and avoid them.

Symptoms associated with gum swelling at the back of the mouth

Gum swelling in the post mouth is usually associated with symptoms. These symptoms are especially evident when brushing or flossing. Common symptoms include:

  • Redness and inflammation: One of the most common symptoms of gingivitis is redness and inflammation of the gums. Your gums may be sensitive to the touch.
  • Bleeding gums: In the situation that you notice bleeding of gums while brushing or flossing, it could be a sign of swelling.
  • Pain or sensitivity to touch: This problem can cause pain or sensitivity in the gums. You may also experience pain when chewing or biting.
  • Receding gums: This problem can also cause receding gums, which can make your teeth appearance look longer.
  • Loose teeth: In severe cases, your teeth may become loose and eventually fall out.
  • Other symptoms may include bad breath, bad taste in the mouth, and pain when chewing. In severe cases, pus may be present, indicating infection.

How to identify the cause of swollen gums

A complete dental examination is necessary to diagnose the cause of gum swelling. In each case, the dentist will review other symptoms, as well as the person’s medical history, to determine the underlying cause of the problem. And X-rays may be used to check for underlying problems such as impacted teeth or bone loss. Regarding gingivitis in children, it should be said that lack of oral and dental hygiene is the main cause of the problem.

Home treatment for swollen gums

For mild cases of gum swelling at the back of the mouth, most cases can be managed with home remedies, but these methods should not replace a dental visit and treatment. If you are currently in a situation where you need immediate treatment for swollen gums and a temporary pain reliever, you can try the following safe ways:


Washing with warm salt water:

The results of a valid study in 2016 showed that washing the mouth with salt water can be useful in healing inflamed gums. In fact, salt is a natural antiseptic that helps the body heal itself.

Saltwater can soothe inflammation, help reduce pain, kill bacteria, remove food particles, and eliminate bad breath. Note that while washing your mouth with water and mouthwash, try to get it to the back of your mouth as well.


Cold compress:

Putting a cold compress on the face can help decrease inflammation and swelling of the gums. In fact, ice cream is one of the simplest home remedies for gingivitis and is effective in most cases.


Washing with hydrogen peroxide:

Diluted hydrogen peroxide is a relatively strong substance that is available in pharmacies without a prescription. Using this substance can help to kill bacteria and heal gum swelling at the back of the mouth.


Essential oils

Some essential oils can also improve general oral health. For example, according to some research, mouthwashes containing essential oils reduce plaque and inflammation in people with gingivitis better than medicated mouthwashes.

Another study shows that mouthwash containing lemongrass oil reduces plaque and is better than conventional medicated mouthwashes in the immediate treatment of swollen gums. Of course, experts believe that more research should be done in this field.

If you are going to use this method to treat gingivitis at home, make sure that the mouthwash does not contain strong ingredients such as alcohol. Such substances can further irritate the gums.

Of course, you can also prepare their home version yourself: mix one or two drops of the desired oil in a cup of warm water and rinse your mouth with it. Thyme, peppermint, clove, and tea tree essential oils are great for this.

Treatment of swollen gums ; Medical options

The discussion of home treatment of gingivitis and immediate painkillers aside, you must agree with us that the medical treatment of swollen gums starts with a visit to the dentist.

In principle, regular visits to the specialist for examination and cleaning of the teeth help to identify and prevent oral and dental problems (before they become advanced) in most cases.

To treat gingivitis, the type of medicine or therapy recommended by the dentist will depend on the underlying cause, And it can include the following:

  • Medicated mouthwashes
  • ointments
  • Specialized toothpaste
  • Surgery (in case of severe inflammation)
  • Scaling and leveling the root surface to remove plaque and tartar


When to See a Dentist for Swollen Gums

If you have swollen gums, in mild cases, you can try to solve the temporary causes with home methods. But if the swelling of the gums at the back of your mouth lasts for more than a week or if it is accompanied by severe pain or signs of infection (such as pus), it is necessary to see a dentist.

Recommendations of a dentist to prevent gum swelling in the back of the mouth

We reviewed several home remedies for gingivitis and, of course, medical treatments. It is good to be familiar with ways to prevent this complication.
