1. What is wisdom tooth gingivitis?

Gingivitis over wisdom teeth is a common inflammatory reaction,broadcastborn whenwisdom teeth(tooth number 8) tries to grow in limited space at the end of the jaw. Due to the special locationspecialIn this case, wisdom teeth often do not have enough room to grow upright like other teeth, leading to a tendency to grow crooked, tilted, or only partially erupt. This condition of incomplete tooth eruption creates a structure called a "hooded gum pocket".

Impacted wisdom teeth cause gums to swell and become inflamed

The gum pocket is a soft flap of gum that covers part of the wisdom tooth surface. The space between the gum flap and the tooth is an ideal place for food debris and bacteria to accumulate. Cleaning this area is often difficult due to its hidden location and the protection of the gums.

The continued accumulation of bacteria in this anaerobic environment stimulates an inflammatory response, causing the swelling, pain, and possibly pus symptoms that characterize wisdom tooth gingivitis.

Signs of redness and swelling are most noticeable when gingivitis covers wisdom teeth

Gingivitis is a common dental problem, and early recognition of symptoms is important in protecting oral health. Below are typical signs that may appear in people with wisdom tooth gingivitis: 

Swelling and redness of the wisdom tooth gum area

The gum area surrounding the growing wisdom tooth often becomes swollen and brighter red than other gum areas. This is one of the initial and most noticeable signs.

Pain and discomfort

Pain is a common symptom, which can range from a long-lasting dull pain to severe pain, especially when chewing or touching the inflamed gum area. Sometimes, the pain can spread to nearby areas such as the ears, throat or temples.

Pustules

The appearance of yellow or white pus from the gum area is a clear sign of infection and should be treated by a dental professional.

Bad breath 

Bacteria and food trapped in the gum pockets can create an unpleasant odor, affecting confidence in communication.

Difficulty opening mouth mouth

In some cases, swelling and pain in the gum area around the wisdom teeth can limit jaw movement, making it difficult for you to open your mouth wide or chew and swallow food.

If any symptoms appear in the last molar area, especially signs of swelling, pain, pus discharge or bad breath, see a dentist soon for examination, diagnosis and advice on effective treatment for gingivitis covering the wisdom teeth.

3. Treatment of wisdom tooth gingivitis

Treatment of wisdom tooth gingivitis needs to be individualized based on each patient's specific condition, with the goal of reducing symptoms, addressing the cause and preventing recurrence. Main treatment methods include:

Temporary treatment 

Focus on reducing pain, swelling, and controlling infection during the acute inflammatory phase.

Measures include thorough oral hygiene at home and may be assisted by a doctor, rinsing the mouth with saline or antibacterial solution, using antibiotics as prescribed by the doctor when there is widespread infection, and using pain relievers and anti-inflammatory drugs to reduce unpleasant symptoms.

Gingivectomy

Indicated for cases where wisdom teeth grow straight or almost straight, have enough space to fully grow, and the gingiva is small. This procedure uses a traditional surgical scalpel, dental laser or high-frequency electric scalpel to remove excess gums. It should be noted that this method has a high risk of recurrence if wisdom teeth continue to grow crookedly or there is not enough space.

Wisdom tooth extraction

Wisdom tooth extraction is the optimal solution for wisdom teeth that are crooked, impacted, causing recurring infections or at risk of complications. The procedure includes examination and diagnosis with X-ray film (CT Cone Beam 3D), effective local anesthesia and tooth extraction with specialized tools. Wisdom tooth extraction is indicated in cases that cause complications and is safe and effective when performed by a qualified dentist.
