A bacterial infection is to blame for teeth infection symptoms. Periapical abscesses are abscesses that develop at the tip of a tooth. Periodontal abscesses are gum-related abscesses. However, dental abscesses aren’t always uncomfortable. They should have a dentist have a look at them in either scenario.
Abscesses don’t go away on their own, so it’s critical to get medical attention as soon as you can. They can occasionally cause you to become ill by spreading to other areas of the body.

Teeth infection symptoms and signs
The following signs of a gum or tooth abscess may appear:
- a sharp, stabbing pain in the tooth or gum that may start off unexpectedly and develop worse over time.
- on the same side as the troubled tooth or gum, discomfort that radiates to your ear, jaw, and neck.
- severe pain when you lay down, and it makes you difficult to sleep.
- swelling and redness in your face.
- a tooth that is sensitive, discolored, or loose.
- gums that are red, swollen, and glossy
- intolerance to hot or cold food and beverages.
- having poor breath or a nasty taste in your mouth
- you can also experience overall malaise and a high temperature (fever) if the infection spreads.
In extreme circumstances, you could find it difficult to fully open your mouth and struggle to breathe or swallow. Some of the most common tooth abscess symptoms in children and adults may be any of the following:
01. Teeth Infection Symptoms: Fever
In most cases, tooth pain and fever on their own are not cause for concern. But if you also have a fever, it’s likely that you have an infection of some kind. There are a number of causes for this, including an untreated injury, dental illness or decay, or a tooth abscess.

Fever is one of the frequent teeth infection symptoms in or around a tooth, and toothaches can occasionally be accompanied by it. Dental infections are major health problems because, if addressed, they can spread to important brain regions. Risks to one’s life can result from a brain infection.
02. Teeth Infection Symptoms: Face Swelling
Visit a dentist if you have a fever and facial swelling. Likewise, if you experience difficulty breathing or swallowing, visit the emergency department. These signs may point to a deeper illness in your jaw, throat, or neck, or possibly in other parts of your body.
An abscess in the mouth could take several months to form. Once an abscess has developed, there will typically be noticeable pain and swelling near the affected tooth. If the infection is not medicated in time, it can take a long time of more weeks or months to heal. It becomes more prone to infect other tissues and become problematic.
Why does a dental infection cause facial swelling?
It denotes the formation of a fluid-filled pocket (pus) at the end of a tooth root in your jawbone. More serious infections could spread to the face if the infection is not treated (facial cellulitis). Your face swells as a result of tooth abscess. Skin and underlying soft tissues are infected in facial cellulitis.

It could spread to the jaw, ear, or skull as well as impact one tooth or many teeth. The gums, other soft tissues in the mouth, the jaw, or the face may experience swelling (inflammation). These signs are probably related if you have swelling around an infected tooth.
03. Teeth Infection Symptoms: Difficulty in jaw movement
Trismus, commonly known as lockjaw, is a painful disorder where the jaw’s chewing muscles constrict and occasionally swell, impairing the ability to fully open the mouth. It is a common sign of tooth abscess and wisdom tooth abscess.
For the majority of people, fully expanding the mouth involves doing so beyond 35 millimeters (mm) wide, or around two fingers’ breadth. Numerous issues might occur when the mouth’s opening action is inhibited. These include troubles with eating and swallowing, poor oral hygiene, and even speech impediments.

Trismus is not prevalent in the general population, although it can occur often in select groups, especially in people who:
- have had their wisdom teeth removed by dental surgery.
- have had head and neck cancer in an area where mouth-moving structures are present.
- having undergone head and neck surgery or radiation therapy.
Tetanus, which is sometimes referred to as lockjaw, is not the same as trismus. The bacterium Clostridium tetani is what causes tetanus, which is an infection.
Tetanus is one of the rare teeth infection symptoms in the United States since there is a vaccine to prevent it. Tetanus can, however, result in severe muscle spasms and stiffness that can happen anywhere in the body. This commonly affects the head and neck region, where it can lead to trismus.

What is the duration of it?
The majority of the time, trismus is transient and goes away in about two weeks. However, if left untreated, it can occasionally take longer to go away and possibly become permanent. In people who develop fibrous tissue as a result of radiation therapy, trismus might also remain longer and be more resistant to traditional treatments.
04. Teeth Infection Symptoms: Sensitivity to hot and cold
It’s one of the teeth infection symptoms if a tooth is extremely sensitive for more than three or four days and responds to both hot and cold conditions. Sensitivity may indicate a cavity or diseased pulp in the tooth. Tell the dentist when the pain first appeared and whether there is anything you can do to relieve the discomfort, such as applying a warm compress.
Your dentist may suggest a course of therapy if you are diagnosed with sensitive teeth, including in-office procedures (applying a desensitizing chemical or a protective covering to the teeth) and take-home goods for individual use. Your dentist could advise root canal therapy if your tooth sensitivity is severe and chronic or if there are no other options available.
