Properly performed filling should permanently relieve a person from painful sensations, but sometimes the tooth still continues to hurt, even after a few months.
Let us consider in more detail why a tooth hurts under a filling and how to cope with such an unpleasant symptom.
A tooth hurts under a filling: the main causes
Most often, tooth pain occurs for the following reasons:
1. The pain that occurs immediately after the operation is called "reactive pain." Like any intervention, each dental procedure is in a sense a trauma, because a doctor can remove parts of a tooth, clean caries, and inject drugs into the gums. For example, after treating pulpitis, people may still experience discomfort for a long time, and even pain after filling. In addition, discomfort can also occur when the teeth are closed. Typically, after a few weeks, this symptom disappears.
2. An incorrectly established diagnosis can cause serious complications in the condition. For example, if the attending physician instead of pulpitis treated ordinary caries and simply filled the tooth, then the probability of true disease progression is high. In addition, it is important to know that in chronic form, untreated pulpitis can lead to complete tooth loss.
3. Severe overheating of a sealed tooth can cause aching pain. This problem occurs in the absence of special cooling, which must be used when preparing teeth.
With overheating of hard tissues, the patient has a burn and pulp necrosis develops, which provokes severe pain. In especially severe cases, overheating can provoke the development of periodontitis.
4. An improperly installed bite of the seal can also provoke stitching pain. This medical flaw can be explained by the fact that most cases of filling are performed under anesthesia (the entire oral cavity of a person is numb), so the patient simply does not feel whether a new filling is interfering with him or not. When a person comes home and begins to talk or eat, he clearly feels discomfort and pain in the tooth. Fortunately, this problem is easily solved. You just need to contact the dentist, who will clean off the excess material for the filling.
5. Polymerization stress. It can cause modern light fillings, which over time cause shrinkage of materials and pain in the tooth. Most often, such a pathology occurs when the technology for establishing light fillings is not observed.
A tooth hurts under a filling: additional reasons
Pain in a filled tooth does not always occur. This is the exception rather than the rule. Pain during the installation of a filling can occur in the first two days after the procedure, and this is considered acceptable, however, if the pain persists and continues to bother further, it is necessary to identify the source of its occurrence.
Additional reasons due to which a person may be disturbed by pain in a filled tooth are:
1. Individual patient intolerance to the metal contained in the filling material. As a result, a person may show swelling, pain in the tooth and redness of the gums.
2. The incompetence of the doctor and his desire to save money can cause terrible discomfort in a filled tooth. At the same time, a person will suffer from pain when eating cold, hot and even sweet food.
3. Poor cleaning of the tooth cavity can lead to the development of secondary caries and, accordingly, to new pain. It is important to know that advanced forms of caries can cause total tooth extraction.
4. Periodontitis often becomes a source of tooth pain under a filling. With this disease, an inflammatory process develops in the deep tissues under the tooth, which is often accompanied by infection.
In severe forms of periodontitis, the integrity of the bone tissue is violated, causing an unpleasant sensation of a “grown tooth”. Because of this, even with a light touch on a diseased tooth, a person will startle from terrible pain. Also, unpleasant symptoms can be given to the ears, the area of the temples and the back of the head. This condition requires immediate medical treatment.
5. Pulpitis. Most often, it develops as a result of untreated (neglected) caries. This disease is accompanied by acute paroxysmal pains of a tooth under a filling, which usually disturb a person at night. Pulpitis can also turn into a chronic form - then the pain will occur periodically.
6. Tooth cyst. It can develop for quite a long time (from two months to several years). You should know that in the initial stages it practically does not cause any pain, but in an advanced state it can provoke severe pain. This disease is quite dangerous because it provokes the destruction of bone tissue (teeth and jaw). If you do not treat it in any way, then the cyst will cause weakness, migraine, fever and sinusitis.
With a cyst, a tooth can hurt not only during meals, but also at rest. Thanks to modern medical techniques, dentists can save a person from this neoplasm, while maintaining the integrity of the tooth.
A tooth under a filling hurts: symptoms
Toothache in a filled tooth may have the following character:
1. Pain that occurs when biting on a tooth that is filled. The cause of this may be an inflamed nerve, as well as non-cleaned dental canals. Some people suffer such pain, believing that it will pass over time, but this is a big mistake, because painful conditions can lead to infection and severe inflammation.
2. Aching pain that occurs after treatment. As a rule, it intensifies after undergoing anesthesia, when all receptors become sensitive again.
3. Acute throbbing pain can signal the development of an infectious process. In addition, if pus collects under the tooth and gum, then the person will have bad breath and a high fever. In severe cases, the cheek near the tooth may swell and redden.
A tooth hurts under a filling: what to do
Toothache is considered one of the most difficult to tolerate. In order to reduce it as soon as possible, it is necessary to adhere to such recommendations:
1. Do not eat too cold or too hot food. The best option is food at room temperature.
2. Observe oral hygiene at least twice a day.
3. Rinse the oral cavity with a strong chamomile decoction or infusion of mint and sage.
4. For severe pain, you can rinse a sick tooth with a solution of soda (1 tsp. Soda in a glass of water).
5. Closely monitor the condition of the tooth: if the gums around it turn red, fester, or it develops a swelling, you should consult your dentist as soon as possible.
6. Apply a gauze swab dipped in valerian tincture to the diseased tooth. This will help relieve acute bouts of pain.
In addition to folk methods, toothache can be dealt with with the help of medications (analgesics). The most effective drugs of this pharmacological group are:
• Dentol (gel that is applied directly to a sore gum or tooth);
• Cholisal (a gel that is used in the same way as Denthol);
• Nurofen (may be in tablets or syrup for oral administration);
• Dexalgin (tablets).
There are also special tooth drops, which are called: "Drops for teeth." They help to quickly relieve pain, however, before using them, it is recommended to consult your doctor.
What can not be done when a tooth hurts under a filling:
• you can’t inject any medications into your gums, as this should be done exclusively by the dentist;
• it is impossible to warm a sick tooth, since such a procedure will only contribute to the development of the inflammatory process and infection;
• it is not recommended to use traditional medicine to quench toothache without prior coordination with your dentist;
• You can’t try to remove the filling from the tooth yourself, even if it is unbearably painful (in any case, you will only make it worse);
• Do not apply ice to the tooth (this can lead to frostbite).
