When you have an infection in tooth tissues, it can quickly go from a small nuisance to a painful and serious condition.
A tooth abscess, also known as a dental abscess, occurs when bacteria invade the tooth or surrounding gums and create a pocket of pus. Left untreated, the infection spreads and may lead to severe complications affecting the upper or lower jaw, gums, and even your general health.
Understanding the mouth infection and dental abscess symptoms, their causes, and the available dental treatment options can help you see a dentist as soon as possible and prevent complications.
What is a tooth infection?
Definition of a tooth infection
A tooth infection, or tooth abscess, is caused by a bacterial infection that creates an accumulation of pus in the affected tooth or gum line. It can present as a periapical abscess, which starts at the tooth root, or a periodontal abscess, which develops in the gums.
In severe cases, the abscessed tooth may affect both the tooth enamel and the surrounding tissues, leading to throbbing pain and swollen gums.
How it differs from other dental problems
Unlike temporary issues such as tooth sensitivity to hot or cold temperatures or mild gum irritation, an abscess is a sign that bacteria have invaded deeper layers of teeth and gums.
Dental abscesses involve a pocket of pus that cannot heal on its own, making it different from routine discomfort caused by sugary foods or worn tooth enamel.
Common symptoms of a tooth infection
Localised pain and sensitivity
The most common symptom of an abscessed tooth is throbbing toothache that may get gradually worse.
You might also notice discomfort when eating soft foods or when consuming hot or cold food and drink. Pain can feel intense in the affected tooth and may radiate into the upper or lower jaw.
Swelling in the gums or face
Swollen gums, sensitivity, facial swelling, and bad taste in your mouth are other frequent signs. In some cases, the swelling may cause difficulty opening the mouth fully or chewing.
Bad breath or a bitter taste can also result from pus discharge at the gum line.
Signs the infection is spreading
Fever and general malaise
If you feel generally unwell, develop a high temperature, or experience a bad taste that does not go away, the infection may be spreading.
A dental abscess left untreated can quickly affect other parts of the body.
Difficulty swallowing or breathing
In severe cases, infection spreads beyond the tooth root and gums, making it difficult to swallow or even causing difficulty breathing.
If these symptoms occur, you should see an emergency dentist or seek urgent medical attention as soon as possible.
Main causes of tooth infections
Untreated tooth decay
One of the most common causes of developing dental abscesses is untreated tooth decay.
When a sticky film on teeth called plaque builds up on the surface, bacteria feed on sugary foods and drinks, producing acids that weaken tooth enamel. Over time, bacteria invade the tooth root and create a dental abscess.
Gum disease and poor oral hygiene
Gum disease is another leading cause. If plaque is not removed properly, it irritates the gums, leading to infection and a periodontal abscess.
Using a soft toothbrush, fluoride toothpaste, and an interdental brush helps to keep teeth and gums healthy and reduces the risk of infection.
Risk factors to be aware of
Lifestyle and dietary influences
Regular consumption of sugary foods and drinks increases the risk of tooth decay and infection. People who fail to brush their teeth at least twice a day may find that their teeth and gums become more prone to developing dental abscesses.
Eating soft foods alone will not protect against bacteria, and hot or cold food may trigger tooth pain if the enamel is weakened.
Medical conditions that increase risk
People with a weakened immune system for medical reasons are more likely to experience severe cases of infection. Conditions such as diabetes can make it harder for the body to fight a bacterial infection.
Smoking and poor oral health practices also play a role in increasing susceptibility.
Treatment options available
Antibiotics and pain relief
In many cases, dentists prescribe antibiotics to help manage infection, particularly when swelling or fever is present. This may be combined with pain relief to reduce throbbing pain.
Warm mouth rinses with salt water can be a temporary solution for easing discomfort, but they do not remove the pocket of pus. Reading the medicine leaflet carefully is important to ensure safe use.
Root canal treatment and tooth extraction
For a restored tooth or an abscessed tooth, a dentist determines the best dental treatment option.
A root canal treatment involves removing the infected pulp, cleaning the canal, and sealing the tooth. A local anaesthetic is used during the procedure. If the tooth cannot be saved, extraction may be necessary.
In some cases, a small incision in the gum line is made to drain the pus. This is done to prevent complications and is usually a temporary solution before further treatment.
Preventing future infections
Daily oral hygiene habits
Preventing dental abscesses requires consistent care. Brush your teeth with a soft toothbrush and fluoride toothpaste twice a day, and use an interdental brush to clean between teeth.
Protective toothpaste can help maintain tooth enamel. Keeping teeth clean also reduces bad breath and unpleasant taste in your mouth.
Warm saltwater rinses may support gum health but are not a replacement for brushing.
Regular dental check-ups and professional cleaning
Visiting a dentist regularly is one of the best ways of preventing dental abscesses.
A dentist can identify early signs of infection in tooth or gum line, provide advice on oral health, and recommend professional cleaning. This helps keep teeth and gums clean and bright, free from plaque and lowers the chance of an infection caused by a bacterial buildup.
Regular visits also ensure that any restored tooth remains in good condition and that soft foods or changes in food and drink habits do not negatively affect oral health.

FAQs
What are the different types of mouth infections?
Mouth infections can affect the teeth, gums and surrounding tissues. A common type is a tooth abscess, which happens when bacteria invade the tooth root or pulp, forming a pocket of pus. A periodontal abscess develops in the gums and can cause swelling, pain and sensitivity. Periapical abscesses form at the tip of a tooth root, while untreated gum disease may also lead to infections along the gum line.
Other infections include bacterial or fungal infections of the tongue, cheeks or roof of the mouth. Thrush is a fungal infection, while viral infections, such as cold sores, can appear around the lips and mouth.
Are mouth infections contagious?
Yes, some mouth infections can be contagious, depending on the cause. Viral infections, such as cold sores, are easily spread through close contact, kissing, or sharing utensils. Certain bacterial infections may also be passed between people, especially if there is direct contact with saliva or infected tissue.
Fungal infections like thrush are less commonly contagious but can sometimes spread, particularly to those with a weakened immune system. Good oral hygiene, avoiding sharing food and drink, and seeing a dentist promptly if you have an infection can help reduce the risk of passing it to others.
What are the risks of untreated mouth infections?
Untreated mouth infections can lead to serious problems. A tooth abscess or periodontal infection may cause severe tooth pain, swollen gums, and a bad taste in your mouth. The infection can gradually worsen, damaging the tooth, gum line, and surrounding tissues, sometimes requiring more complex dental treatment such as root canal treatment or extraction.
In severe cases, the infection can spread to other parts of the body, causing fever, difficulty swallowing, or difficulty breathing. People with a weakened immune system are particularly at risk. Seeking prompt dental care helps prevent complications and protects overall oral health.
How long does it take for a mouth infection to heal?
The healing time for a mouth infection depends on its type and severity. A small gum infection or minor abscess may improve within a few days with proper care, including warm saltwater rinses, good oral hygiene, and any prescribed antibiotics. Pain and swelling usually start to reduce gradually once treatment begins.
More severe infections, such as a periapical abscess or deep tooth infection, may take longer to heal. Root canal treatment or tooth extraction may be needed, and full recovery may take one to two weeks. Following your dentist’s advice helps ensure faster healing and prevents complications.
Can stress cause mouth infections?
Stress itself does not directly cause mouth infections, but it can increase the risk. When you are stressed, your immune system may be weaker, making it harder for your body to fight bacteria in the mouth. This can make it easier for infections, such as gum disease or tooth abscesses, to develop.
Stress can also affect oral health habits. People under stress may brush their teeth less regularly, eat more sugary foods, or grind their teeth, which can damage tooth enamel and gums. Maintaining good oral hygiene and managing stress can help reduce the risk of mouth infections.
Will a mouth infection cause tooth loss?
Yes, a mouth infection can lead to tooth loss if it is left untreated. A tooth abscess or severe gum infection can damage the tooth root, surrounding gums, and supporting bone. Over time, this damage can weaken the affected tooth, making it more likely to fall out or require extraction.
Prompt dental treatment can prevent tooth loss. Procedures such as root canal treatment, drainage, or other dental treatment can save the tooth. Maintaining good oral hygiene, using fluoride toothpaste, and visiting a dentist regularly also help protect teeth and gums from infections that could lead to permanent tooth loss.
Is there ever a time I would need to see a doctor, not a dentist, for a mouth infection?
There are times when a mouth infection may require seeing a doctor instead of a dentist. If the infection spreads beyond the mouth, causing difficulty breathing, swelling in the face or neck, or a high temperature, urgent medical attention is needed. These are signs that the infection could affect other parts of the body and may become serious.
People with a weakened immune system or existing medical conditions may also need to see a doctor. While a dentist treats the infection in the tooth or gums, a doctor can manage any wider health risks and prescribe appropriate medication if necessary.
How can I manage the symptoms of a mouth infection at home before I see a dentist?
You can manage the symptoms of a mouth infection at home before seeing a dentist by keeping the area clean and reducing discomfort. Rinse your mouth with warm saltwater several times a day to help reduce swelling and kill some bacteria. Using a soft toothbrush and fluoride toothpaste can help keep your teeth and gums clean without causing extra irritation.
Over-the-counter pain relief can help ease throbbing toothache or swelling, and sticking to soft foods or avoiding hot or cold food and drink may reduce sensitivity. Make sure to see a dentist as soon as possible for proper treatment.
Can mouth infections come back after they have been treated?
Yes, mouth infections can come back after treatment, especially if the underlying cause is not fully addressed. For example, a tooth abscess may return if bacteria remain in the tooth root or if the tooth is not properly restored. Gum infections can also recur if plaque and bacteria continue to build up along the gum line.
Good oral hygiene is essential to prevent recurrence. Brushing your teeth twice a day with fluoride toothpaste, using a soft toothbrush and interdental brush, avoiding sugary foods, and visiting a dentist regularly can help reduce the risk of mouth infections returning.
