A toothache is an unpleasant sensation that can affect anyone, regardless of age or health. Teeth are composed of hard and soft tissue, nerves, and blood vessels. When at least one part of this complex structure malfunctions, pain occurs. It can be sharp, stabbing, persistent, or intermittent, and
Tooth decay is one of the most common dental issues. It occurs when damaged enamel, caused by bacteria and acids, forms on the surface of the tooth. Initially, tooth decay may go unnoticed and cause no symptoms.
Over time, the hole penetrates deeper, reaching the dentin layer and causing pain. It most commonly manifests when eating sweet, cold, or hot foods. If left untreated, tooth decay progresses and affects the pulp, the inner part of the tooth where the nerves run. This leads to pulpitis and severe pain. The only way to treat caries early is with a filling.
Pulpitis is an inflammation of the dental pulp that occurs with advanced caries or dental trauma. It is accompanied by severe, often throbbing pain that can worsen at night. The pain can radiate to the temples, ears, or even the jaw, making it particularly distressing.
Home remedies and painkillers only provide temporary relief for pulpitis. Treatment requires a visit to the dentist: The doctor cleans and fills the dental canals. If pulpitis is left untreated, it can develop into periodontitis and cause complications.
A tooth abscess is a collection of pus that forms when the tissue around the tooth becomes inflamed. It is accompanied by severe pain, swelling of the cheek or gums, and fever. With an abscess, the pain becomes almost unbearable, and the affected person can no longer chew or open their mouth normally.
This condition requires urgent medical attention. The dentist will open the abscess, clean the affected tissue, and prescribe a course of antibiotics. Attempts to treat an abscess yourself can lead to serious complications.
Sometimes a toothache is not caused by the tooth itself, but by gingivitis. Gingivitis and periodontitis are diseases in which the gums become red, swollen, and begin to bleed. In such cases, pain occurs when chewing or brushing teeth.
As the inflammation progresses, teeth may become loose. Moreover, chronic gingivitis poses a health riskit can increase the risk of cardiovascular disease. Professional teeth cleaning and subsequent treatment by a periodontist are necessary for treatment.
Periodontitis develops when the inflammation spreads beyond the tooth and affects the tissue surrounding the root. It is most often a complication of untreated pulpitis. Symptoms include severe pain when chewing, bad breath, and the formation of pus-filled lesions.
As periodontitis progresses, fistulas and even abscesses can form. This is dangerous for the entire body, as the infection can spread to other organs. Treatment includes cleaning the root canals, antibacterial therapy, and sometimes surgery.
Wisdom teeth are a common cause of toothache. They begin to erupt between the ages of 17 and 25. For many people, this process is accompanied by gum inflammation, pressure on neighboring teeth, and pain. Sometimes a wisdom tooth grows in the wrong wayat an angle or sideways, leading to deformation of the dental arch.
The pain during eruption can be very severe and may be accompanied by swelling and difficulty opening the mouth. In such cases, the dentist may recommend wisdom tooth removal. You can search for "dentist near me" to find an experienced and qualified specialist in your area.
In addition to the conditions described above, a toothache can also be caused by injuries, cracks in the tooth enamel, increased tooth sensitivity, or even by conditions not directly related to the oral cavity. For example, a toothache can be caused by sinusitis. In any case, it is better to visit a dentist for a thorough examination and proper treatment.
