A tooth abscess is a bacterial infection that causes pus to collect at the root of the tooth or between the tooth and the gums. An abscess is caused by severe tooth decay, untreated cavities, or injury to the tooth.

Thus, recognizing this problem early is very important to prevent the infection from spreading.
Recognizing a Tooth Abscess
Observe the pain in the teeth. Tooth pain is one of the common symptoms of an abscess. This pain is often caused by the pus pressing on the nerves in the teeth. You may feel a stabbing pain around the tooth, or a sharp, sharp pain in that area. Pain may also be felt when you bite, and even make it difficult for you to sleep.
Pain may only be felt around the teeth, but can also radiate to the ears, jaw, and cheeks.
Pain may be accompanied by a tooth that feels like it is moving.
Do not assume the abscess has healed when the pain in the tooth subsides. Most likely the abscess has killed the root of the tooth, and the infection is still there.
Pay attention to the pain you feel when you eat or drink. The abscess will make you feel pain when chewing. An abscess can also make your tooth sensitive to hot and cold temperatures. Visit the dentist if these symptoms do not improve.
Pericoronitis abscess is a problem that can occur near the lower wisdom teeth. This type of abscess can cause the masseter muscle to lock (also known as trismus) so that you can barely open or close your mouth.
Watch for swelling. As the infection spreads, swelling will occur in the mouth. The gums may appear red and swollen, and may be painful. These symptoms are commonly encountered in periodontal abscesses.
The gums on the aching tooth may also swell. This swelling may resemble a pimple.
Watch for a bad taste or odor in the mouth. If the abscess bursts, you will feel or smell the pus coming out. Bitter taste. Visit the dentist immediately.
Check for other symptoms. The condition of the abscess that worsens may cause a fever. You may also have difficulty opening your mouth and swallowing. Swelling of the glands or the upper and lower jaw may also occur, and is often accompanied by general malaise. Immediately visit the dentist if these symptoms begin to feel.
If the abscess ruptures, the pain may suddenly disappear, but a salty taste will appear. Immediately visit the dentist if this happens.
Visit the dentist. If you feel the above symptoms, visit the dentist immediately. The dentist can check for tooth sensitivity. You may also be asked to have an X-ray examination. After that, the dentist can tell for sure if you do have an abscess.
Tooth abscess is a serious problem. You should visit the dentist as soon as possible. The dentist can determine the cause of the abscess, prescribe pain medication, and antibiotics, and treat the abscess with medical procedures (such as cleaning the abscess, administering root canal treatment, or extracting a tooth).
Preventing Tooth Abscess
Keep your teeth clean. Brush teeth 2 times a day. In addition, try to clean between your teeth with floss ( flossing ) once a day. You are at a higher risk of developing an abscess if you neglect dental hygiene.
Avoid sweet foods. The risk of cavities is higher if you frequently eat foods rich in sugar (such as candy and chocolate). Cavities in the teeth over time can lead to abscesses. Some sweet foods are okay to eat as long as you don’t overdo it. If possible, try to brush your teeth afterward.
Watch out for cavities and cracks in your teeth. You are at risk of developing an abscess if a hole or crack in the tooth reaches the dental pulp (the inside of the tooth). This occurs when bacteria enter the tooth until it reaches the pulp. Visit the dentist as soon as possible, and be aware of the symptoms.
Holes and cracks in the tooth will eventually lead to a periapical abscess.
Watch your gums. Injury to the gums can cause an abscess. Gum disease causes the gap between the teeth and gums to widen, allowing bacteria to enter. These bacteria can cause abscesses, even if your teeth are healthy and without cavities. Watch for symptoms of an abscess if you have a problem with your gums.
Injury to the teeth and gums generally results in a specific infection known as a “gingival abscess” or gum abscess. If this infection extends to the gum pocket, and blocks the discharge of pus, you will develop a periodontal abscess.
