What causes the gums of the back molar teeth to swell and painfull?

When the gums swell, there are usually harmless causes behind it. Nevertheless, it is important to diagnose and treat possible gum inflammation or other related illnesses early on.

There are a number of possible causes of swollen gums. In the case of insufficient or excessive hygiene of the oral cavity, swelling can occur just as much as during pregnancy or temporarily after a treatment at the dentist. However, serious gum diseases such as periodontal disease can also be the cause.

Have you ever had a sudden swelling of your back gums in molar areas?. It makes chewing miserable and excludes all hard food from the menu. Gum swelling in molar areas is more frequent due to their increased function and complex root structure than those of the anterior teeth and also due to the presence of wisdom teeth.

If the gums of your back teeth are swollen, the bite will hurt and you will have difficulty in eating. Here, we will introduce the causes and treatments for swelling of the gums of the back teeth.

Causes of swelling of the gums of the back teeth

Tooth root diseases in Back Molar Teeth as a Cause of gum swelling

The most common cause happens when tooth decay reaches the tissue portion of the tooth and causes infection and necrosis.

Back molar teeth are more prone to decay due to the presence of grooves on these teeth, which are difficult to clean after eating. Decay can quickly reach the pulp tissues even though the tooth shows no cavity apparently. Decay reaching living tissue in tooth cause pain and infection.

When a tooth nerve dies, a bag of pus forms at the tip of the root of the molar tooth. This is called an apical lesion. When this apical lesion grows, pus accumulates inside and the gums become swollen. Other symptoms include pain when chewed and floating teeth (tooth is mobile).

In particular, molars often have more roots and are more complex than anterior teeth, so even teeth with treated roots may have apical lesions. Weak root canal procdure or restoration can result in the apical lesion and cause repeated gum swellings later on.

In this case, root treatment is required. It disinfects the inside of the tooth root that is infected with bacteria and treats it so that the apical lesion becomes smaller. If the infected root canal treatment does not help, surgery is done to remove part of the root canal and the bag of pus.

Periodontal disease melts the bone around the molar teeth

As periodontal disease progresses, the periodontal pockets deepen, melting the bone around the teeth. Then, pus accumulates there and the gum swell.

When you press the gum, pus may come out and the teeth may shake. In particular, the back teeth have a strong biting force and plaque tends to remain, so it is a place where periodontal disease easily progresses.

In this case, it is treated with periodontal tissue regeneration therapy that regenerates the bone melted by periodontal disease. When the gums are swollen, the periodontal pocket is 5 mm or more. If the periodontal pocket is deep, it is not easy to remove the plaque that has accumulated inside.
Periodontal tissue regeneration therapy is performed to make the periodontal pocket shallower.

Wisdom teeth are growing

If wisdom teeth grow sideways or if the gums are covered, plaque tends to accumulate and the gums become swollen. Wisdom teeth rarely grow straight, and often grow diagonally or sideways.

Therefore, the plaque around the wisdom tooth cannot be removed with a toothbrush and may swell.

Wisdom tooth swelling often repeats, so it's a good idea to extract your teeth as soon as possible. In particular, there are times when it becomes difficult for women to extract teeth due to pregnancy. Considering the surrounding teeth and cavities, it is recommended to extract teeth around the age of 20.

There is a hole in the molar tooth (decay)

If the molar tooth is punctured by tooth decay, it can easily become clogged with food waste and fibers, which can compress the gum and cause them to swell. Molars are prone to clogging with food debris, so elderly people and children may not notice it and their gums may swell significantly.

In this case, dental caries treatment is required. However, periodontal tissue regeneration therapy may be required because the bones around the teeth may also be lowered in areas where food waste has been contained for a long period of time. Leaving cavities adversely affects not only the teeth but also the surroundings of the teeth. Therefore, regular medical examinations at the dentist's office are required.

The gums under the bridge are rising

A bridge is a method of connecting the lost tooth with the front and back teeth. The bones and gums of the lost tooth may swell and cause pain when the prson bite with the bridge.

Also, the cause may be unknown, and need xray for cleear diagnosis, as the bridge, which has had no problems for more than 10 years, may suddenly swell.

In this case, if the bridge is in good condition, a portion of the bridge that hurt the gum is removed. Also, if the bridge is deteriorated or has cavities, a redo of the bridge is the best option

My teeth are broken

If you have strong bruxism or clenching, or if you have no nerves, your teeth may crack. Bacteria can enter through these cracks and cause the gums to swell.

In this case, if the tooth is cracked and the crack is small, fix it with adhesive and cover the tooth to prevent bacteria from entering through the crack. Also, if it breaks big, you need to pull out your teeth.

Oral hygiene as a cause of swollen gums

Inadequate oral hygiene can also be a trigger for swollen gums in the second step if it leads to inflammation of the gums.
If harmful bacteria contained in the dental plaque attack the gums and lead to foci of inflammation, gingivitis, and, as a result, periodontitis, which manifests itself in swollen and red gums, among other things.

In the same way, excessive oral hygiene can cause swelling if too much pressure is exerted on the gums with the toothbrush.

Swollen gums after dental treatments

The gums can become inflamed and swell, especially after a major treatment, for example after the removal of wisdom teeth or a root canal treatment. However, complaints of this kind are mostly temporary and completely normal. If they do not go away on their own after a few days, the dentist should be visited again.

Swollen gums in babies and during pregnancy

Swelling of the gums also occurs in children and babies. When the first teeth appear around the age of six months, this causes tension in the jawbone and as a result, the gums can swell, which can be accompanied by itching, pain, and sometimes even fever.

Likewise, swollen gums and bleeding gums can occur during pregnancy, mainly because of the changed hormone level, as a result of which the oral mucosa is supplied with more blood than before. Because the actually firm tissue structure becomes looser and bacteria can penetrate more easily, this increases the risk of inflammation of the gums and the associated swelling.

Canker sores as a cause of swollen gums

This unpleasant damage can occur in various parts of the oral cavity, such as the gums, the insides of the lips, the roof of the mouth, the tongue, and the tonsils. Usually, canker sores are milky in color, surrounded by an inflammation-red border. Aphthae can cause severe pain, burn and itch.

Aphthae can arise from various causes, but their origin is not fully understood. Genetic factors can play a role in inflammation, as can the person's psyche. A weak immune defense, sometimes due to stress, can promote the development of canker sores.

Possible causes of canker sores are also:
Food intolerance
Viral infection
Bowel disease
hormonal situation
uncomfortably fitting dentures and braces
A toothbrush that is too hard or the wrong toothpaste
severe immune diseases such as HIV

Why is the gums of the back molar teeth swelling easily?

So why are the gums of the molars more prone to swelling than the anterior teeth? Here are some possible reasons.

Because plaque tends to remain on the back teeth
Plaque is more likely to remain on the back teeth when brushing than on the front teeth. Therefore, tooth decay and periodontal disease are likely to progress, causing swelling of the gums.

It is important to brush your teeth carefully every day, but it is recommended that you regularly clean your back teeth, which are difficult to brush, at the dentist's office.

Because the back teeth are used to apply strong force
Molars are said to exert as much force as their weight. As a result, the teeth are shaken and periodontal disease is likely to progress, and in the worst case, the teeth may crack. Also, if you have bruxism, the filling may come off or the ceramic may crack.

If necessary, consult your dentist and take measures such as using a bruxist mouthpiece.
Molar treatment is often postponed
Most people go to the dentist's office immediately when their anterior teeth become cavities, but even if their back teeth become cavities, treatment may be postponed.

Caries can progress even without pain, causing swelling of the gums, death of nerves, and pus buildup at the tips of the roots, causing the gums to swell.

First aid when swollen gums

If your gums are swollen or have severe pain, you should see your dentist immediately, but know how to deal with them as first aid, such as at night or on holidays.

Swelling of the gums is usually due to inflammation and accumulation of pus. It causes dull and throbbing pain. You can reduce the pain by cooling it from the outside with a wet towel or ice pack.

Commercially available pain reliever
If the pain is severe, you can relieve the pain with over-the-counter painkillers. If you endure the pain, you tend to lose your appetite, so it is important to reduce the pain and get proper nutrition. However, even if the pain disappears, it is important to see a dentist.

Disinfection of the mouth
Mouthwash is effective not only for inflammation of the throat but also for killing bacteria on the gums, so disinfect it with mouthwash. Alcohol-based mouthwashes can irritate swelling, so be sure to use over-the-counter mouthwashes.

Recovery of physical strength
Swelling of the gums may worsen when you are tired or sick because your resistance is reduced and you cannot control the growth of bacteria. In addition to the first aid measures introduced above, try to keep your body calm and recover your strength.

Use a soft toothbrush
Not brushing your teeth just because your teeth are swollen and painful is not good because it increases the number of bacteria in your mouth. Try to brush with a softer toothbrush than usual.

Care to prevent swelling of the gums

Swelling of the gums is mainly due to bacteria that grow on the plaque that accumulates in the gaps between the teeth and gums. So think of it as a sign that you should improve your daily self-care. In other words, it is important to continue and improve daily self-care.

Brushing with awareness of the boundary between teeth and gums
Periodontal disease bacteria live in the mouth, and especially the boundary between the teeth and gums is a place where bacteria grow and plaque easily accumulates. If you occasionally suffer from swelling of your gums, practice brushing with an awareness of the boundary between your teeth and gums.

Use toothpaste that acts on periodontal disease bacteria
There are various types of toothpaste on the market, such as those that claim to have a whitening effect, prevent bad breath, and prevent tooth decay. If you have a favorite toothpaste, you can't replace it with a different toothpaste. However, if you suffer from swelling, you should choose a toothpaste that acts on periodontal disease bacteria.

Let's review the toothbrush
If you are familiar with toothbrushes, you will not have a chance to change them, but considering that it is important to polish each one carefully, a small head is recommended. If you have swelling or bleeding, choose one that is soft and has fine tips.

Let's use an electric toothbrush
If you're brushing your teeth for a short time, or if you're still not brushing your teeth because of the refreshing feeling of toothpaste, you may want to try an electric toothbrush. It is attractive to be able to effectively care in a short time.

Make a habit of rinsing your mouth after eating
It is desirable to brush your teeth thoroughly after each meal, but it can be difficult to establish a habit. If you can't brush after eating, just rinsing your mouth is effective in removing food debris and reducing bacterial growth. Of course, if you have the time to brush, it's better.
