Key Takeaways
- A tooth abscess appears as a white, pus-filled boil on the gums and cheeks. These may bleed or rupture at the end stage, causing intense pain due to tender, swollen gums. Painless, white lumps cannot be confused with an abscess.
- Tooth infections are the most common cause of dental abscesses. But not all tooth infections lead to abscess formation. Dental injuries, foreign objects, and a weakened immune system also lead to abscesses.
- Poking or cutting an abscess to drain it at home worsens the infection. Dentists combine antibiotic therapy with root canal therapy or tooth extraction to effectively treat dental abscesses. When left untreated, an abscessed tooth can lead to life-threatening conditions.

Dental Infection and Abscess
The oral cavity is home to thousands of bacterial species. Some are beneficial bacteria, others are harmful, causing tooth infections. Tooth infections are serious, leading to hospitalization in about 1 in 2,600 people in the United States.[1] They occur when oral bacteria enter the tooth structure, causing pulp infection and inflammation. This bacteria spreads to the surrounding bone or gum tissue, forming localized pus pockets, called tooth abscesses.
Dental abscesses formed near the root tip of the infected tooth are called periapical abscesses. These result from pulp infection and are more common in non-vital teeth, which have lost access to their blood supply.[2]
On the other hand, periodontal abscesses are localized pus boils within the periodontal pockets. These spaces develop when the gums pull away, creating an opening for bacterial build-up and potentially causing infection.[3]

Dental Abscess Versus White Lumps On Gums
A dental abscess appears as white lumps on the gums, but not every white lump or pimple can be a tooth abscess. Typically, gum boils of infectious origin, and those causing intense pain are abscesses. Painless, smooth bumps, on the other hand, can be canker sores, fibroma, leukoplakia, oral thrush, oral lichen planus, and gingival cysts. A professional dentist can diagnose the actual origin.
Dental Abscess Versus Tooth Infection
Most people confuse a tooth infection with a dental abscess. Overlap of symptoms, intense pain, tooth sensitivity, and swollen gums, makes the terms used interchangeably.
Tooth infection is the general term for bacteria invading dental tissues. Oral bacteria enter the tooth structure and establish a population in the dental cavity. This is diffused through the pulp and is spreading across the pulp and bone. This tooth infection, when it forms a pus-filled localized pocket, is called a dental abscess. To put it straight, all dental abscesses involve an infection, but not all tooth infections can become abscesses.
Understand the Tooth Abscess Reasons
A tooth abscess can develop for several reasons. Below, is clear break down:
- Untreated tooth infections are the primary cause of dental abscesses. Enamel is the outermost and hardest part of the natural tooth. The bacteria enter the interior of the tooth through small crevices or cracks in the enamel. It infects the soft dentin layer and the pulp, containing the nerves and blood vessels. From there it easily spreads to the surrounding jawbone and gum tissues. Tooth abscesses form when bacteria spread, causing a buildup of pus either within the gums or at the infected tooth root tip.
- Gum diseases (periodontal issues), plaque buildup and tartar, provide breeding grounds for bacteria. Compromised oral hygiene increases the bacterial load, making your teeth vulnerable to chronic infections. Gingivitis, especially due to bacterial infection below the gumline, can lead to the formation of pus pockets between the teeth and gums.
- Dental injuries cause chips, breaks, and cracks within the teeth. Bacteria can enter the tooth structure, leading to pulp infection and dental caries. These are a direct cause of dental abscesses.
- Inappropriate dental work, such as a failed root canal treatment, or leaky fillings leaves uneven, open edges, cause gum inflammation. Furthermore, dental decay underneath fillings or crowns is a sign of root canal reinfection, a leading cause to a tooth abscess.
- Foreign bodies, such as toothbrush bristles or food particles like popcorn husks, become trapped between teeth or beneath the gum line. Routine oral hygiene measures, like brushing and flossing, cannot remove them. This leads to gum irritation, creating pockets of pus near the gum line.
- A slowed-down immune response cannot effectively kill the bacterial infection. Candidates suffering from chronic diabetes, HIV, or autoimmune diseases or undergoing cancer treatment, have a weakened immune response. Their body fails to launch a stronger immune response against the growing infection. As a result, the bacteria invade the deeper tissues, and the body is unable to control them, leading to the formation of pus.
How Can You Tell if You Have a Tooth Abscess?
The tooth abscess appears as small pimples or boils filled with pus near the infected tooth on the gums. Note that dental abscesses do not develop overnight. Early-stage abscesses are often overlooked. The symptoms are simple and seem more like tooth sensitivity. Here we listed stage-wise visual symptoms for better identification.
- Early-stage abscesses: Tooth abscesses in their early stages do not have a visible boil. The early stage abscess in mouth cheek and gums near the affected area typically appears tender, swollen, and reddish. A few candidates experience facial swelling, especially on the cheeks near the infected tooth. Slight sensitivity and dull, persistent pain are common indications of early-stage dental abscesses. Most people ignore this stage, but the treatment is straightforward.
- Middle stage abscesses: A small, visible white or yellowish bump appears gradually. Symptoms include throbbing pain that radiates along the ear, jaw, and neck. Some candidates experience swollen lymph nodes in the neck.
- End-stage abscesses: At this stage, symptoms are more pronounced. Throbbing pain that eases when the abscess ruptures with foul-tasting pus oozing out. Bad breath is more noticeable with a sudden rush of foul taste.
While these are the visible symptoms of a tooth abscess, we have listed a few other signs you should be aware of.
- Dental abscesses due to pulpal infection are typically characterized by intense, deep-seated pain. The infected pulp swells, exerting pressure on the tooth and causing intense pain.
- Increased sensitivity to too hot or too cold foods, especially when you bite on them. It occurs due to weakened enamel and dental caries.
- A persistent bad taste or foul smell in the mouth due to bacterial growth and the draining of pus.
- Difficulty with chewing even the soft foods, mainly due to tooth sensitivity and pus-filled boils. In the worst cases, even chewing and eating are challenging.
- Fever is one of the common symptoms of tooth infection spreading to body. Bacterial spread into the systemic blood circulation results in a rise in body temperature.
In severe bacterial load or a weakened immune system, you will experience symptoms of a tooth infection spread to other parts of the body. These include fever, rapid heartbeat, chest pain, difficulty breathing, difficulty swallowing, headaches, fatigue, and general tiredness. While these are the noticeable symptoms, many patients ask us if the symptoms of a tooth abscess often go unnoticed.
Can You Have a Tooth Abscess and Not Know It?
Early stage dental abscess may not cause noticeable pain. However, most patients experience pain and tenderness from a dental abscess until it bursts and pus is released. In rare cases, the pain may not be experienced when the infected tooth suffers nerve damage, due to a previous implant procedure, severe tooth decay, or trauma. Note that a painless tooth abscess cannot be neglected. The severity remains the same, requiring prompt care.
How Long Can You Have a Tooth Abscess Without Knowing?
The tooth abscess can go unnoticed between several weeks and to a few months. While most dental abscesses cause noticeable pain, a few can go unnoticed, especially during their early stages. Early detection is crucial to the successful management of tooth abscesses. Attending regular dental check-ups helps in the early detection of tooth infections.
Can You Have a Tooth Infection Without an Abscess?
Yes, it is possible to have a tooth infection without an abscess. Note that a tooth abscess is one common outcome of dental infection but not its guaranteed possibility. In some patients, a dental infection can lead to a pulp infection and may necessitate root canal treatment. In others, it may spread to the surrounding jawbone or gum tissue. In a few cases, it may even enter the systemic blood circulation and spread the dental infection to the heart and brain. In rare cases, it can also block the airways, leading to death.
A tooth abscess is dangerous, and should not be ignored. Whether it's a painful or a painless pus pocket, your tooth abscess requires prompt dental care. If you're unsure about your symptoms and asking yourself, "How do I know I have a tooth abscess?", there are signs only a dentist can confirm.
How Does a Dentist Confirm the Presence of a Tooth Abscess?
Your dentist will perform a physical examination by looking at the affected tooth. They will check for visual symptoms of redness, swelling, and drainage. Further, they also check the sensitivity to touch, heat, and cold temperatures. Dental X-rays detect the extent of infection, track the presence of pus, the extent of bone damage, and the spread of infection within the oral cavity. In advanced stages of infection, dentists may perform CT scans to identify the spread of the infection to areas such as the neck and face.[4] Additionally, thermal tests evaluate the viability of the inner tooth pulp. Alongside, undergoing routine blood tests will help you assess the severity of the infection and the extent of its spread.
What To Do if You Have an Abscess Tooth?
Book a dental appointment if your teeth are affected by a dental abscess. Your dentist will confirm the presence of a tooth abscess and discuss the treatment options with you. Treatment depends on the infection severity and the immune response. An antibiotic dosage (such as Amoxicillin, Metronidazole, Azithromycin, or Cefoxitin) usually accompanies it. [5]
- Draining a tooth abscess: Dentists make small incisions near the affected tooth to drain the pus. They disinfect the area using a saline solution and keep it open by placing a rubber tube in the wound.
- Root canal therapy: RCT is required in cases of pulp infection. Dentists drill a tiny hole within the infected tooth and clean the root canals. They remove the debris and infected tooth pulp. Next, they seal the cleaned root canals using filling material and cover the tooth with a crown to prevent further bacterial entry.
- Tooth extraction: Your dentist will extract the tooth in case it's severely damaged and cannot be saved. They perform a safe extraction procedure to cut off the spread.
Will a Tooth Abscess Go Away With Antibiotics?
A dentist will prescribe antibiotics alongside dental treatment. Antibiotics kill the bacteria and prevent their spread. This reduces the bacterial load, and abscess symptoms, such as redness and tenderness, will slowly subside.
But antibiotics cannot be a standalone treatment. Studies suggest that antibiotic treatment alone, without a dental approach, typically fails.[6] The American Dental Association issued treatment guidelines for apical abscesses, emphasizing the elimination of infection.[7] A professional dental treatment, such as abscess drainage, root canal therapy (RCT), or extraction, is necessary. It cannot be substituted for over-the-counter remedies.
When Will I Feel Better After Treatment for a Dental Abscess?
The pain, inflammation, and sensitivity will reduce in a few days after prompt dental treatment. You will initially experience discomfort from the surgical incisions made for pus drainage. This will heal gradually. Note that the healing time varies with the patient's overall health condition. Prolonged healing period is a sign of a persistent infection or delayed healing. Don’t hesitate to see your dentist if your healing process takes longer than a week.
What Do I Do if I Need To Wait for a Dental Appointment?
A few dental appointments may demand long wait times. While you wait for the dental appointment, following a few home remedies eases the pain and swelling. Below are some common at-home practices that people with tooth abscesses adopt along with their effectiveness.
- To reduce redness and tenderness around the gums, gently swish warm salt water in the mouth.
- Avoid consuming foods that are too hot and too cold to prevent tooth sensitivity.
- Eat soft, easily chewed foods, such as yogurt, scrambled eggs, and mashed potatoes.
- Refrain from eating high-sugar foods and from frequent snacking to slow bacterial progression.
- Use a soft-bristled toothbrush and avoid brushing too hard, as this can worsen inflammation and potentially rupture the abscess.
While a few people recommend using hydrogen peroxide or baking soda, it's better to avoid them. Excessive or even limited use (in cases of sensitive gums) can irritate the gums, delay healing, and even cause chemical burns.
How To Get Rid of a Tooth Abscess Without Going to the Dentist?
Only a dentist can safely and effectively treat a dental abscess. Painkillers only offer temporary pain relief and are not a real solution. Home remedies also serve as a temporary relief from the pain and discomfort. These cannot address the root cause.
How To Get Rid of Swollen Face From Tooth Infection?
Your dentist should drain the tooth abscess for you to relieve the facial swelling it causes. Schedule a dentist consultation immediately. While you wait for your appointment, you can follow these measures to manage the swollen face.
- Apply a cold compress to slow down the blood flow to the affected area. This will also reduce inflammation and swelling.
- Sleeping upright with your head elevated can help reduce fluid buildup.
When Is an Abscess Tooth Considered a Medical Emergency?
Any dental abscess needs immediate treatment. The chances of infection spreading and worsening the situation are quite high. A dental abscess may even cause death when the bacteria spreads systemically. Individuals with a compromised immune system are more prone to dental infection death. Consider a dental abscess a medical emergency when the following symptoms accompany it.
- High fever, along with fatigue and tiredness
- Swollen lymph nodes around the neck
- Bleeding gums
- Severe facial swelling, with swollen eyes
- Altered mental stage, confusion
- Severe pain with difficulty swallowing or opening their mouth
- Secretions within the mouth that are difficult to handle due to swallowing issues

An abscessed tooth that spreads can cause a puffy face, swollen eyes, or an extension of swelling over the jaws toward the neck. Alongside fever, confusion, dizziness, and loss of visual clarity are other symptoms. A ruptured abscess is often associated with fluid drainage and causes a foul taste.
Abscesses, in general, are pockets of pus formed within the body tissues due to bacterial infection. They appear as white pus-filled boils. Dentists confirm their presence through visual examination, dental X-rays, CT scans, thermal imaging, and blood tests.
An abscessed tooth that goes unnoticed can occur in its early stages. Middle- and advanced-stage abscesses cause intense pain, making them easily noticeable. However, a few candidates may experience nerve damage, which can make it difficult to detect.
It can take a few days to a few months, or in some cases, several years, for a tooth infection to cause death. While not every tooth infection can kill the individual, the chances of death are higher in immunocompromised patients and those with underlying chronic health conditions. Candidates undergoing chemotherapy, those suffering from autoimmune diseases, and those with problematic heart valves are more prone to death. More importantly, this also depends on the bacterial load and the severity of the infection. However, with prompt medical care, this can be avoided.
An abscess tooth causes intense pain, and appears as pus boils on the gums and cheeks near the affected tooth. This is accompanied by gum irritation, swelling, and redness, with a foul odor and taste. While some patients experience bleeding gums, a few notice dental abscesses that rupture with fluid oozing out.
You should not drain a gum abscess at home, as it can only worsen the condition. Poking or pressing gum abscess may push the bacteria into the surrounding tissue spaces. More importantly, attempting to drain a gum abscess at home can lead to the spread of infection.
A tooth abscess in its starting stages appears too small and negligible to the naked eye. Candidates experience gum irritation and inflammation. Tooth abscesses are visible as small pus-filled boils during their middle and advanced stages.
No, a tooth abscess cannot go away on its own. They require dental treatment, such as surgical abscess drainage, root canal therapy, or extraction, along with an antibiotic regimen. When left untreated, a tooth abscess can even lead to life-threatening situations.
