Tooth extraction is a surgical procedure that creates an open wound surface in the gum. The body initiates a natural healing process, in which a blood clot plays a key role. It forms the first few minutes after the operation and acts as a ‘biological bandage’. If the clot falls out or breaks down, the tissues remain unprotected. This condition is called ‘dry socket’ or post-extraction alveolitis in dentistry. According to Wikipedia (based on reviews and systematic studies), alveolitis (dry socket) occurs in 0.5-5% of cases after routine tooth extractions and in 25-30% of cases after surgical removal of lower (mandibular) wisdom teeth. Therefore, it is essential to understand what routine healing looks like, why the loss of a clot is dangerous, and what measures need to be taken. Dry socket after tooth extraction

How does the socket heal after tooth extraction?

Immediately after extraction, the vessels in the alveolus walls begin to contract actively. The blood coagulation system forms a clot that performs several functions:
  • covers the bone tissue and prevents infection;
  • protects nerve endings, reducing sensitivity and pain;
  • provides a basis for the growth of granulation tissue;
  • starts the process of epithelial regeneration.
Healing of a blood clot Healing proceeds in stages:
  1. Days 1-3 — clot formation and stabilisation, onset of inflammatory response, fibrin formation.
  2. Days 3-7 — active filling of the socket with granulation tissue, partial healing of the gum margins.
  3. 2-3 weeks — closure of the wound with the mucous membrane.
  4. 2-6 months — complete restoration of bone tissue.
In some cases, the surgeon applies a suture after tooth extraction. This accelerates regeneration, holds the wound’s edges together and reduces the risk of clot loss.

What does ‘dry socket’ mean, and what does it look like?

A dry socket is a pathological condition with no protective clot. The surface of the bone tissue remains open and exposed to microbial influence. The following signs can visually identify a dry socket:
  • absence of a burgundy clot, instead of which a bare-bones wall is visible;
  • a grey or yellowish coating at the bottom of the alveolus;
  • swelling of the gums, sometimes accompanied by an unpleasant odour;
  • increased pain on the 2nd or 3rd day.
Patients often confuse this condition with routine healing. However, the pain usually increases with a dry socket and becomes more intense each day.

Why does the blood clot fall out?

The causes of the clot loss or destruction can be local and general. Local factors:
  • mechanical washing out during active rinsing;
  • eating hard or hot food in the area of the surgery;
  • injury with a toothbrush;
  • smoking or using a straw, which creates negative pressure.
Smokers are 3-4 times more likely to develop dry socket. General factors:
  • diabetes mellitus;
  • blood clotting disorders;
  • low immunity;
  • chronic infections.
The patient’s behaviour is worth mentioning separately. Failure to follow the doctor’s recommendations is the leading cause of complications. Violating the rules of care and ignoring the list of things not allowed after tooth extraction increases the risk of clot loss several times.

Symptoms of dry socket and alveolitis

Symptoms of alveolitis When the clot is absent, infection easily penetrates the open alveolus, causing inflammation — alveolitis. The main signs are:
  • pain, intensifying 2-3 days after surgery;
  • unpleasant smell and taste in the mouth;
  • swelling and redness of the gums;
  • weakness, low-grade fever (between 37.1 and 38.0 °C);
  • enlargement of regional lymph nodes.
These are typical signs of alveolitis, requiring professional intervention.

What does a normal clot look like?

A normal clot is dark red and gradually becomes denser. Sometimes it is covered with a whitish film of fibrin — this is not pus, but a sign of routine healing.

When does the clot fall out?

Most often, in the first 24–72 hours, while it is still unstable. Later, the risk decreases, but it cannot be completely ruled out, especially in the case of trauma or eating hard food.

What to do if the clot falls out?

Treatment of alveolitis Self-medication is unacceptable in such cases. If the patient notices that the socket is empty, they should:
  1. Immediately consult a dentist.
  2. Avoid any rinsing or mechanical action.
  3. If necessary, take painkillers prescribed by a doctor.
Treatment of a dry socket The KES clinic uses modern treatment protocols:
  • curettage of the socket — careful removal of necrotic tissue;
  • treatment with antiseptic solutions;
  • application of medicated dressings with analgesics and antimicrobial drugs;
  • if necessary — systemic antibiotics and painkillers;
  • physiotherapy (laser therapy, UHF) to accelerate regeneration.
In cases of severe inflammation, the doctor diagnoses alveolitis of the tooth socket and prescribes comprehensive treatment. The pain subsides in 3-5 days with proper treatment, and the socket heals in 7-10 days.

Prevention of clot loss

Prevention begins immediately after surgery. Doctor’s recommendations:
  • do not rinse your mouth for the first 24 hours;
  • do not touch the wound with your tongue or objects;
  • refrain from smoking and alcohol for at least 2-3 days;
  • avoid hot food and drinks;
  • brush your teeth with a soft brush, avoiding the area of the surgery;
  • if necessary, take the prescribed antibiotics.
Additional tips:
  • in the first few hours, apply cold to the cheek to reduce swelling;
  • sleep on a high pillow to minimise bleeding;
  • follow a gentle diet — yoghurt, mashed potatoes, soups at room temperature.
Research by The Journal of the American Dental Association shows that using chlorhexidine-based rinses (0.12%) before and after tooth extraction can reduce the risk of alveolitis by 40-50%. This is due to reduced bacterial load in the oral cavity. Regular check-ups with your dentist allow complications to be identified on time. A blood clot after tooth extraction is a natural protective mechanism without which routine healing is impossible. Its loss leads to the formation of a ‘dry socket’ and the development of alveolitis. In such cases, visiting a dental clinic as soon as possible is essential. Our KES doctors have over 24 years of experience and use modern methods to treat complications. This allows them to stop inflammation quickly, restore tissue, and prevent serious consequences. Following recommendations and paying close attention to your health will help patients avoid complications and make recovery as comfortable as possible.
