ᐈ Bruise after tooth anesthesia: causes of occurrence, why it is dangerous, how to treat

Injection anesthesia is the most common method of anesthesia in dentistry.

Many people experience discomfort after dental treatment. Quite often, patients begin to experience pain from the administration of the anesthetic.

The problem is addressed after a day from all dental procedures, since before that the painkillers were still in effect. If your gums hurt after an anesthesia injection and the discomfort only increases within 24 hours, you should immediately contact the clinic.

After treatment and tooth extraction, pain often occurs at the site of injection of the anesthetic. Sometimes pain can be accompanied by swelling and impaired sensitivity of the soft tissues of the oral cavity.

Possible reasons for the appearance of a lump on the gum after tooth anesthesia

Since the doctor makes the injection blindly, there is a risk of hitting a blood vessel. This explains why a bruise appears on the cheek or gum. In many cases it is considered the norm. Hematoma may also occur while taking certain medications that affect the blood's ability to clot. This could be, for example, Heparin, Aspirin, and many NSAIDs. A number of factors contribute to the appearance of a lump after the administration of an anesthetic:

drinking alcoholic beverages before visiting the dental office;
high blood pressure - hypertension;
consuming too hot food or drinks shortly after dental treatment.

Swelling near the injection site is not considered a deviation from the norm. Often such manifestations are subjective in nature - a person may feel severe tissue swelling, although in fact the swelling is insignificant. But in some cases, these signs can lead to complications, so it is necessary to understand when the pathological process develops.

How long does dental anesthesia last?

This is another important point. It is important for the patient to know that it will not hurt and to understand how long the dental anesthesia lasts. The last factor can be decisive for planning work functions for the rest of the day. Insensitivity increases the risk of injury to the tongue and mucous membranes, which is why dentists recommend refraining from eating and active speech. In the case of conduction anesthesia, problems with diction and swallowing may occur.

find out how long dental anesthesia lasts in your particular case from your attending physician. He selects 1 drug or combination and selects the dosage. The effectiveness of pain relief will depend on the sum of these criteria.

How many hours does it take for the tooth to be anesthetized depends on the drug and dosage

Drugs with a short duration of analgesia give an effect for 30-60 minutes. For example, novocaine “works” for up to 1 hour, but in combination with adrenaline, the duration of action is extended to 90 minutes.
The average duration of anesthesia for infiltration injection with lidocaine is 1.5-2 hours.
Ultracaine - gives a high effect, lasts up to 5 hours, and Bupivacaine can freeze the injection area for up to 8 hours.

to predict exactly how long anesthesia will last for dental treatment for a particular patient only by taking into account all individual factors. Your doctor can guess the average exposure time, but it may vary.

Why does pain occur after an injection into the gum?

Since the needle is inserted into soft tissues, it injures them and provokes discomfort. The patient may feel pain at the injection site for 1-2 days, or even more. The duration of the recovery period depends on the characteristics of the body and the perception of stimuli at the neuropsychic level.

Overly sensitive patients should be prepared for aching pain. Most often, no action is required. Usually the pain subsides on its own. In the case when it does not go away and only gets worse over time, we can talk about the development of a complication. At the same time, other signs of disturbances may occur.

Sometimes the patient thinks that the injection site hurts, but the localization is in a different place. So, after caries treatment, you may feel aching pain that radiates to the gums. Removal of a wisdom tooth is accompanied by pain in the socket, while the patient thinks that the problem is localized at the injection site.

Features of anesthesia

Today in dentistry, pain relief is very often used by injecting an anesthetic with a syringe. This is convenient for the dentist and makes it possible to reliably turn off sensitivity during any surgical interventions. You can learn how the most common types of pain relief in dentistry are performed by watching the video in this article.

Infiltration and conduction techniques are mainly used. The big advantage is that this allows you to act locally without having a toxic effect on the entire body.

Infiltration anesthesia is carried out directly in the area of the problem area. Conduction anesthesia affects the branch of the nerve responsible for a specific area of innervation. This technique is necessary for more extensive medical interventions.

Infiltration anesthesia on the upper jaw

Many people are concerned about the question: does it hurt to give anesthesia to the gums? Of course, the procedure is not pleasant.

Before carrying out the manipulation, for particularly sensitive patients, dentists irrigate the injection site with anesthetics in an aerosol. However, recently very thin needles have been used for carpule syringes, which minimally injure soft tissues.

Complications after injection of anesthetic into the gums

Depending on the amount of blood released from the vessel and the individual characteristics of the body, it often takes 4 to 10 days for a bruise on the gum to disappear. Otherwise, this is already a complication.

Type of complication	Features of manifestation	Symptoms
Accession of infection	There are always millions of bacteria in your mouth. In a normal state, they are in a certain balance, but under favorable conditions, for example, when immunity decreases, they can be activated. Thus, clotted blood becomes a nutrient medium for them. Pathogens begin to multiply. Pathogenic microorganisms can spread to periodontal tissue, the alveolar process that holds the tooth, periosteum and bone. Much depends on the type of pathogen and the location of the bruise.	Tissue infection is accompanied by the following symptoms: · painful sensations; · temperature increase – up to 39 ˚С; · weakness; · headache; Redness of the gum tissue.
Damage to the nerve trunk	If the doctor acts incorrectly, nerve fibers may be damaged as a result of the administration of anesthesia. In this case, it is important to contact a neurologist and maxillofacial surgeon as quickly as possible.	The patient feels a sharp pain immediately when the injection is given. It will subside for the duration of the anesthetic, but then resume again. It cannot be stopped even with the help of painkillers. If a large nerve trunk is affected, pain will be felt throughout the entire mouth, cheek and ear. It is even possible to turn off the chewing function and numbness of the face. Sometimes it is difficult to open your mouth completely; one side may sag.
Tissue necrosis	A very dangerous complication. The reason for its development may be the patient’s ailment, which he was silent about, vasospasm, too much anesthetic or its rapid administration.	The patient first feels a sharp, growing pain. It subsides for a short time, but this does not indicate that the danger has passed. The pain disappears due to tissue death.

Complications after tooth extraction often occur due to the penetration of bacteria through the hole into various tissues of the dentofacial apparatus. Pus accumulates.

Dangerous symptoms

Today, laser caries treatment is often used. Such manipulations do not cause pain if the dentist follows the technology. No painkillers are required. This therapy technique is especially suitable for those who are afraid of injections. The use of this method of treatment eliminates the drill and vibrations from it. This therapy is also comfortable for the patient.

If you experience an unpleasant symptom after the injection and it does not go away within 3-4 days, you should consult a doctor. Serious symptoms that indicate a problem may include gumboil and abscess, ulcers and spots on the gum tissue, or the formation of a large cyst. In such a situation, you should not hesitate to visit the doctor, so as not to worsen the consequences.

Reason to see a doctor

The following symptoms require a visit to the dental office:

severe pain at the injection site and its increase;
significant swelling of the gums that remains after the anesthesia wears off;
purulent or sanguineous discharge from gum tissue;
temperature increase;
compaction (“petrification”) of gum tissue in the affected area;
looseness of the gums under the tooth, which was amenable to treatment, their slight displacement when exposed.

During the examination, the doctor will determine the cause of the development of undesirable effects.

What can you do at home?

When discomfort is felt in the gum tissues, or a sore throat after dental anesthesia, you need to make an appointment with a doctor. Before going to the clinic, you need to follow simple rules.

Do not include too cold or hot foods in your diet, as the gums are vulnerable and react painfully to irritants.
Teeth should be brushed with a cool brush.
It is impossible to mechanically influence the gingival tissue. The pressure should be light.
Do not apply garlic, pepper, or mustard to the affected mucous membrane.
Several times a day you should rinse your mouth with a salt solution, a water decoction of chamomile or sage. Particular attention should be paid to diseased areas.

Such activities will ease the condition before visiting a doctor. After the procedure, the dentist may prescribe medications to relieve pain. The most commonly prescribed drug is Nise, a strong drug that relieves muscle pain. Ketanov is an effective remedy. Dexalgin acts for a long time and quickly. For minor pain, baralgin is used. Nurofen works well on soft tissues. At elevated temperatures and inflammatory processes, it is recommended to use paracetamol.

Pathogenesis

The occurrence of a hematoma in dentistry is usually caused by mechanical trauma to the oral cavity - unsuccessful surgery, tooth extraction, anesthesia injection. Domestic injuries are possible; people with poor blood clotting and older people are especially susceptible to this disease.

Stages of hemotoma development

Red hematoma is bleeding into the surrounding tissue of red blood cells. Vascular rupture, thrombosis.
Blue hematoma (2–3 days) - venous stagnation, changes in corpuscles.
Green hematoma (4-5 days) - formation and release of hemasiderin.
Yellow hematoma (6-7 days) - resolving therapy is recommended.
If the process lasts for more than a month, ulcers and erosion may develop.

Symptoms

Rising body temperature
Pain on palpation
Spontaneous throbbing pain
Tissue compaction
Tissue swelling
Change in color of damaged skin
Swelling of the mucous membrane

Diagnostic and treatment methods

To exclude hidden lesions of the tooth and soft tissues, the doctor refers the patient to an X-ray. Treatment always begins with removal of pus. The specialist carefully opens the gum and cleans it of dead tissue, after which he treats the cavity with antiseptics. To defeat the infection, the patient must take antibiotics and anti-inflammatory drugs prescribed by the doctor. If pathogenic microorganisms have not penetrated into the deep layers of tissue, this is usually enough to stop inflammation.

If the image shows that the main source of inflammation is in the canals of the tooth, then the filling will have to be removed. The doctor will remove it, thoroughly clean the root canals, place a temporary filling and set a date for a follow-up examination. It will be possible to fill the tooth again only after the photo shows that the inflammatory process has stopped.

Sometimes the cause of suppuration is damage to the apex of the tooth root. To save it, the doctor performs an operation - resection. During it, only the affected root tissue is removed.

Treatment of gum suppuration always includes taking antibacterial drugs. They help destroy infectious agents and prevent relapse.

Physiotherapeutic methods are also widely used in dentistry. Electrophoresis, ultrasound and laser help speed up tissue restoration, increase local immunity, and relieve swelling. Physiotherapy is prescribed only after the inflammatory process has stopped. The duration of the course for each patient is determined individually.

Why do bruises appear after implant placement?

Bruises are formed due to damage to small blood vessels, hematomas are the result of deep damage to soft tissues followed by muscle hemorrhage. Such reactions are located in the gums, but sometimes, due to inflammation in the area where the titanium structure is implanted, they move outward.

Reasons for development:

An insufficiently experienced implantologist - due to inexperience, the facial nerve or artery may be affected.
Intolerance to materials and medications used during implantation.
Anatomical features of the patient’s body (rate of blood clotting, tissue regeneration).
Violations at the stage of preparation for implant installation.
Failure by the patient to follow medical recommendations at the postoperative stage.

How to remove and alleviate the general condition

By following simple recommendations, you can get rid of the complications that have arisen or at least minimize their severity:

After the operation is completed, ice is applied to the site where the implant is installed for 15 minutes . At home, the patient must perform this procedure at least five times a day.
The dentist applies dental paste to the wound to promote speedy healing and reduce discomfort.
The patient should try to be in an upright position more often . At night, sleep on a high pillow to improve blood flow from the wound.
Treat teeth located next to the implant with 3% hydrogen peroxide.
Rinsing the mouth with an antiseptic solution after eating disinfects and promotes healing of damaged mucous membranes.
Avoid spicy, hard, or too hot foods.
To relieve pain, you must take anti-inflammatory and painkillers prescribed by your doctor.
Use heparin-based ointments to speed up the resorption of the hematoma.
To brush your teeth, use a new, soft brush with natural bristles.
Quit smoking for at least 2-3 weeks.
