A dental infection or abscess is a serious condition that will not resolve on its own. Prompt treatment — combining dental intervention with antibiotics where necessary — is essential to clear the infection and prevent it from spreading to surrounding tissue.
A dental infection — most commonly a dental abscess — occurs when bacteria invade the pulp of a tooth (the soft tissue containing the nerve and blood vessels), the surrounding gum tissue, or the bone beneath a tooth. The body's immune response to this bacterial invasion creates the characteristic swelling, heat, and throbbing pain associated with an abscess.
There are two primary types. A periapical abscess forms at the tip of the root of a tooth — typically as a result of untreated decay or trauma that has allowed bacteria to reach and kill the tooth's pulp. A periodontal abscess forms in the gum tissue beside a tooth, often related to gum disease. Both require urgent treatment and, if left untreated, can cause significant damage to the surrounding bone and tissue.

If you have significant swelling, fever, difficulty swallowing or breathing, or an inability to open your mouth fully, do not wait for a dental appointment. Go immediately to a hospital emergency department — these signs indicate the infection may be spreading rapidly.
Effective treatment of a dental infection has two components: eliminating the source of the infection and managing the spread with antibiotics where clinically indicated. Antibiotics alone will not cure a dental abscess — they may reduce the acute phase of the infection temporarily, but the source must be treated for the infection to resolve.
If a localized collection of pus is present, your dentist may make a small incision to allow drainage. This provides relatively rapid relief from the pressure and pain of the abscess and reduces the bacterial load at the site. Drainage may be performed as part of the initial emergency appointment.
If the infection has developed from an infected tooth pulp (a periapical abscess), root canal treatment is typically the tooth-saving option. The infected pulp tissue is removed, the root canals are cleaned and disinfected, and the tooth is sealed and eventually crowned. This eliminates the source of the infection while preserving the tooth.
In cases where the tooth cannot be saved — due to the severity of the infection, the structural condition of the tooth, or patient preference — extraction removes the source of the infection entirely. Appropriate wound care and follow-up are provided after extraction.
Antibiotics are prescribed when the infection shows signs of spreading beyond the tooth itself, when there is systemic involvement (fever, swelling), or as a precautionary measure in high-risk patients. They are used alongside dental treatment, not as a substitute for it.
Most patients experience significant relief relatively quickly once the infection has been drained or the root canal procedure has begun. Some post-treatment soreness is normal and typically managed with over-the-counter pain relief. If antibiotics have been prescribed, it is important to complete the full course even if you begin feeling better sooner.
Following up after an urgent infection appointment is important. Your dentist will want to review the area once the acute phase has settled to assess how the tooth and surrounding tissue are responding and to plan any further treatment needed. Dental infections treated promptly and thoroughly have good outcomes — the important thing is not to delay seeking care. At Smile Spot Mawson Lakes, we are here to help you through it as quickly as possible.
A dental abscess typically causes persistent, throbbing pain around a tooth or in the gum, which may be accompanied by swelling of the face or jaw, a raised bump or pimple on the gum, a bad taste or smell in the mouth, or fever. You may also notice the pain has worsened over several days rather than improving. If you have any of these signs, seek dental assessment urgently.
No. A dental abscess does not resolve without treatment. The bacteria causing the infection continue to multiply, and the infection can spread to surrounding bone, other teeth, or the soft tissues of the face and neck. In rare but serious cases, untreated dental infections can spread to the airway, brain, or heart. Antibiotics may slow the spread but will not eliminate the source — dental treatment is always required.
Antibiotics are prescribed when clinically appropriate — for example, to reduce the spread of infection before dental treatment, or when there is systemic involvement such as fever or facial swelling. However, antibiotics alone are not a cure for a dental infection. The source of the infection — whether a severely decayed tooth, an infected root canal, or infected gum tissue — must be treated dentally. Antibiotics without dental treatment typically provide only temporary relief.
Go directly to a hospital emergency department if you have significant swelling of the face, jaw, or neck; difficulty swallowing or breathing; trismus (inability to fully open your mouth); a high fever; or you feel generally unwell with the infection. These are signs that the infection may be spreading rapidly and require medical management that goes beyond what a dental practice can provide. Do not wait for a dental appointment in these circumstances.
Call Smile Spot Mawson Lakes on (08) 8258 0650. If you have facial swelling, fever, or difficulty swallowing, go to your nearest hospital emergency department immediately.
