Why do wisdom teeth grow?

Wisdom teeth, also known astooth number 8, are the last teeth to grow on the jaw and usually appear between the ages of17 and 25 years old. This is the time when the jaw bone has almost completely developed, so growing one or more wisdom teeth often causes discomfort and many unwanted complications.

Each person can grow1 to 4 wisdom teeth, or in some special cases, none can grow. However, the space in the jaw is often not enough for wisdom teeth to develop normally. Therefore, the situation ofwisdom teeth growing crooked, impacted or impactedis very common. This not only causes prolonged pain but also has many potential risks affecting oral health.

In addition, thewisdom tooth root structureis often complex, the tooth roots are curved or pierce the adjacent teeth, makingwisdom tooth extraction much more difficult and expensive than other teeth.

Because the space in the jaw is often not enough for wisdom teeth to develop normally, the condition of wisdom teeth growing crooked, impacted or Impacted wisdom teeth are very common

Why does wisdom teeth often cause discomfort?

The core problem lies in the lack of space. When wisdom teeth begin to emerge, our jawbone has stopped growing and the other teeth have almost stabilized in position. The jaw does not have enough room for a large tooth like a wisdom tooth to grow straight, leading to a series of ironic scenarios:

Impacted teeth:The tooth cannot fully emerge but is partially stuck under the gum or in the jawbone.
Misaligned teeth:Instead of growing straight, wisdom teeth can grow crookedly toward the cheek, toward the tongue, or most dangerously, pierce horizontally into the adjacent tooth number 7.

In addition, the structure of the wisdom tooth root is also extremely complex. They can have many legs, curved legs, clubbed legs, intertwined... This not only makes the growing process more difficult but also makes tooth extraction (if necessary) much more complicated and expensive than other teeth.

7 signs of wisdom teeth growing

Early recognition of signs of wisdom teeth eruption helps you be proactive in care and treatment. Here it isThe 7 most common signsthat you should not ignore:

Dull pain in the innermost jaw area

This is the classic and earliest sign. The pain can range from dull, annoying to intense, lasting in waves.The cause is because the teeth are in the process of breaking through the gums to grow, creating pressure on the surrounding soft tissues and jawbone.

Gum swelling, redness

The gum area surrounding the growing wisdom tooth will be swollen and redder than usual. When pressed, it may feel painful. Sometimes, this inflammation is also accompanied by unpleasant breath due to bacteria accumulating in inflamed gum pockets.

Jaw pain and stiffness

Pain from the wisdom tooth area can spread throughout the jawbone, even to the temples and ears. Inflammation can affect the jaw muscles, causing symptoms of stiffness, making it difficult for you to open your mouth, eat, chew and communicate.

Mild fever

When the gums are infected due to wisdom teeth growing, the body will respond by increasing its temperature to fight bacteria. You may feel tired and lethargic with a mild fever, similar to having the flu.

Nasal congestion and headaches (especially with upper wisdom teeth)

The roots of the upper wisdom teeth are located very close to the maxillary sinus. When upper wisdom teeth grow, pressure and inflammation can affect the sinuses, causing symptoms such as a dull headache, nasal congestion or a feeling of heaviness in the cheek area.

Loss of appetite

The combination of pain, swollen gums, difficulty opening the mouth and general fatigue makes eating difficult. Patients often tend to lose appetite and skip meals, leading to body weakness.

Swollen lymph nodes in the neck

This is a reaction of the immune system. When there is inflammation in the mouth area, the lymph nodes in the neck (under the jaw) can swell and be painful to the touch.

3 dangerous symptoms of wisdom teeth growing

Not all pain caused by wisdom teeth can be treated at home. If you experience 1 of the 3 dangerous symptoms below, see a dentist immediately to avoid unpredictable complications:

Severe infection (Gingivitis, abscess)

Abnormally swollen gums, red, may ooze white or yellow pus when pressed. The pain is intense, pulsing with the pulse. This is a sign of serious infection. If not treated, the bacteria can spread and cause blood infection, which is extremely dangerous.

Prolonged high fever

Fever above 38.5 degrees Celsius, lasting more than 1-2 days without going down, accompanied by signs of fatigue. This is a sign that the infection is spreading and the body is no longer able to resist.

Misalignment causes serious effects on other teeth

You feel severe pain in tooth number 7 (the molar next to the wisdom tooth), feeling that this tooth is loose or unusually sensitive. It is necessary to take an X-ray to check whether the wisdom tooth is pressing into the root of tooth number 7 or not. This complication can cause damage and loss of the important number 7 tooth.

Wisdom teeth can lead to dangerous gingivitis

5 ways to relieve pain at home when growing wisdom teeth

In case the symptoms are only mild and you cannot go to the dentist right away, try applying the following 5 temporary pain relief measures:

Gargle with warm salt water

This is a simple but extremely effective method. Mix a teaspoon of salt into a glass of warm water, rinse your mouth thoroughly for 30 seconds, focusing especially on the area where wisdom teeth are growing. Salt water has natural antiseptic properties, helping to clean, reduce inflammation and soothe pain.

Cold compress

Wrap a few ice cubes in a clean towel and gently apply it to the outer cheek area corresponding to the position where the wisdom tooth is swollen and painful. Keep for about 15-20 minutes. Cold air will help constrict blood vessels, reduce swelling and temporarily paralyze sensory nerves, thereby effectively reducing pain.

Use pain relievers (As prescribed)

Over-the-counter pain relievers such as Paracetamol or Ibuprofen can help control pain. However, always read the instructions for use carefully and it is best to consult a pharmacist or doctor. Absolutely do not arbitrarily use Aspirin on children or abuse the drug.

Prioritize soft, liquid foods

Stay away from foods that are hard, chewy, crunchy or too spicy, which can cause irritation and further damage sensitive gum areas. Prioritize porridge, soup, smoothies, yogurt... to ensure nutrition while not having to chew too much.

Thorough oral hygiene

Many people tend to avoid brushing teeth in painful areas, but this is a mistake. Maintaining cleanliness is extremely important to prevent further infection. Use a soft-bristled toothbrush to gently clean around the wisdom tooth area. Combine with salt water gargling to thoroughly eliminate bacteria.

Cold compresses will help constrict blood vessels, reduce swelling and temporarily paralyze sensory nerves, thereby effectively reducing pain.
