Many people wake with a toothache that will not go away. They worry about an infection, swelling, or an abscess. An infected tooth can cause sharp pain, a bad taste, pus, and swollen gums.
A tooth abscess is a pocket of pus caused by a bacterial infection near the tooth. This guide covers the common symptoms, the causes — like cavities and gum disease — and the clear treatment steps your dentist takes. It covers antibiotics, root canal care, abscess drainage, and the dental hygiene that prevents the problem from coming back. At Dentist in New Britain, we treat tooth infections quickly, because an infection rarely resolves on its own.
An infected tooth often causes deep, throbbing pain in the affected area. This discomfort usually signals a dental infection. Pain may increase while chewing or applying pressure, and lying down can also worsen the ache.
Swelling around the tooth becomes noticeable as an abscess forms. An abscess appears as a red, swollen bump or pimple in the mouth. Chronic bad breath and an unpleasant taste often accompany this condition. Swollen lymph nodes may also occur with a tooth infection, signaling further complications if the infection is left untreated.
Tooth infections often stem from untreated cavities or gum disease. Bacteria invade the tooth and cause a dental infection, leading to an abscess. This pus-filled pocket forms near the tooth roots as bacteria multiply in decayed tissue. Deep, throbbing pain usually marks the onset of the infection.
Risk factors include poor oral hygiene, which contributes to tooth decay and gum disease. People with weakened immune systems also face a higher risk of developing these infections.
Discomfort may increase when lying down or chewing, and swollen lymph nodes can signal that bacteria have spread beyond the tooth. Chronic bad breath and an unpleasant taste in the mouth point to possible complications from an infected tooth as well.
Antibiotics help fight the bacteria causing a dental infection. Treatments like root canal treatment remove the infected tissue inside the tooth and relieve pain. Over-the-counter pain relievers also help manage a toothache caused by an abscess or gum disease. Swollen lymph nodes may require further medical attention if symptoms worsen. When a tooth cannot be saved, an extraction stops the infection from spreading — and our abscessed tooth treatment guide walks through how dentists drain an abscess.
Preventing a tooth infection starts with good oral hygiene practices. Regular brushing and flossing reduce the risk of cavities and gum disease. Routine dental exams and cleanings can identify problems early, before they lead to something as severe as an abscess. Maintaining overall oral health is crucial to avoiding painful complications from an infected tooth.

A toothache is the main sign. You may also have swelling, pus, or a fever. An abscess — a pocket of pus — can form and cause severe pain.
Bacteria can enter a tooth through a crack or a cavity, or from gum disease. The bacteria then cause a dental infection, which can lead to an abscess and more pain.
Treatment may include antibiotics and a root canal. Endodontics, or root canal care, removes the infected tissue inside the tooth. Your dentist may also drain the abscess for pain relief and to save the tooth.
See a dentist right away for a bad toothache, swelling, or any pus. Don't wait for the pain to pass on its own. Early care protects your oral health and stops a dental infection from getting worse.
Keep good oral health habits by brushing, flossing, and seeing your dentist regularly. Treat gum disease early so bacteria do not reach the tooth. Quick care for small problems can stop a dental infection before it starts.
No, a tooth infection rarely resolves on its own and needs dental treatment. The bacteria sit inside the tooth or gum where brushing and rinsing cannot reach them, so the abscess keeps building. Pain may ease for a few days if pus drains, but the infection is still there. Getting treated early stops it from spreading to the jaw or lymph nodes.
An abscess usually looks like a red, swollen bump or pimple on the gum near the sore tooth. It may leak pus, leave a bad taste in your mouth, or cause chronic bad breath. The gums around it often look puffy, and the face or lymph nodes can swell as well. Fever and a general feeling of illness can also appear.
No. Antibiotics fight the bacteria and calm the swelling, but they do not remove the source of the infection. The decayed or infected tissue inside the tooth still needs treatment, usually a root canal to clean out the infected pulp, or an extraction when the tooth cannot be saved. Skipping that step often lets the infection return.
Pain from an infected tooth commonly worsens when you lie down, and it also increases when chewing or pressing on the tooth. Deep, throbbing pain in the affected area is the classic sign that the nerve is involved. If a toothache is keeping you awake at night, that is a reason to have the tooth examined promptly rather than waiting it out.
Treat the cause and keep up daily hygiene. Brush twice a day with fluoride toothpaste, floss every night, and have cavities filled before decay reaches the nerve. Regular exams and cleanings keep gum disease under control, which is a common route for bacteria to reach the tooth root. Report swelling, pus, or fever right away instead of waiting.
