What are the signs of a tooth infection?

A tooth infection often occurs when bacteria enter the innermost part of a tooth or the surrounding gums. Common signs of a tooth infection include severe toothache and tenderness or swelling in the gums. People may also experience fever. 

Not receiving appropriate dental care and having difficulty recognizing signs of infection can lead to serious complications like tooth loss or blood infections. 

Signs and symptoms of a tooth infection 

The common signs of a tooth infection include:

• persistent and throbbing tooth pain that worsens with pressure or chewing
• swelling in the gums, face, or neck area, possibly around the infected tooth
• increased sensitivity of the tooth to hot or cold temperatures
• fever
• persistent bad breath
• tender and swollen lymph nodes in the neck or jawline area
• redness, tenderness, or bleeding of the gums

When should you contact a dentist?

If you experience any signs of a tooth infection, consider speaking with a dentist as soon as possible. Prompt dental care is important to prevent the infection from spreading and causing further complications. 

Additionally, if you notice any oral health changes like persistent bad breath that does not go away with regular oral hygiene practices, an unpleasant taste in your mouth, or swollen lymph nodes in your neck, make sure to tell a dentist so they can investigate further.

How will a dentist treat a tooth or gum infection?

Treatment options for a tooth or gum infection may include the following:

Antibiotics

Antibiotics are not always necessary for treating tooth infections. They are typically reserved for cases where the infection is severe, spreading, or causing systemic symptoms.

The choice of antibiotic may vary based on factors like the infection type. Commonly prescribed antibiotics for tooth infections include: 

Penicillins

These antibiotics inhibit the growth of bacteria by disrupting how they build their cell wall and bringing water to the cell to kill it. They are effective against many types of bacteria that commonly cause tooth infections. A typical example is amoxicillin (Amoxil).

Cephalosporins

These are similar in structure to penicillins and prevent bacteria from building their cell wall. A dentist may prescribe cephalosporins if you have an infection resistant to penicillin.

Some people allergic to penicillin may also have a cephalosporin allergy, so be sure to discuss any potential allergies with your dentist. Some examples of cephalosporins include cephalexin (Keflex) and cefuroxime (Zinacef).

Macrolides

These drugs work by preventing the growth and reproduction of bacteria. A dentist may prescribe them for tooth infections when you have allergies or intolerances to penicillin and cephalosporins. Examples of macrolides include azithromycin (Zithromax) and clarithromycin (Biaxin).

Pain relievers

A dentist may prescribe pain relievers to help manage discomfort associated with a tooth or gum infection. These may include:

• Nonsteroidal anti-inflammatory drugs (NSAIDs): NSAIDs are a class of pain relievers that can help reduce pain, inflammation, and swelling. They include naproxen (Aleve) and ibuprofen (Advil).
• Acetaminophen: Acetaminophen (Tylenol) can effectively manage pain from tooth or gum infections by reducing pain signals in the brain. This medication is available over the counter and on a prescription from a dentist.
• Opioids: Opioids like combined hydrocodone and acetaminophen (Lortab) are strong pain relievers that healthcare professionals typically reserve for severe pain. They generally offer them for a short duration and under close supervision since they carry the risk of dependence, misuse, and potentially severe side effects.

Root canal procedures

If the infection has reached the tooth’s pulp and become an abscess, a root canal procedure may be necessary to remove the infected tissue.

During a root canal, a dentist will remove the infected pulp from the tooth’s interior and clean and shape the root canals. They will then fill and seal the space to prevent further infection. This procedure typically takes one or two appointments under local anesthesia to ensure a pain-free experience.

Draining the abscess

If there is a visible abscess, a dentist may need to drain it to reduce pressure and inflammation and promote healing.

The procedure involves making a small incision in the abscess to allow the accumulated pus to drain away. Dental surgeons will typically use local anesthesia to numb the area, ensuring your comfort during the procedure.

Tooth extraction

In severe cases where the infection cannot be effectively treated, or the tooth is extensively damaged, tooth extraction may be necessary.

A dentist will use specialized tools to gently remove the infected tooth from its socket in the jawbone during a tooth extraction. They often give local anesthesia to numb the area to ensure you have a comfortable experience. 

Preventing a tooth or gum infection

To prevent tooth and gum infections, it’s important to establish and maintain good oral hygiene habits. This can include:

• Flossing: Flossing daily helps clean the spaces between your teeth and removes plaque or food particles that may be stuck. This helps prevent the buildup of bacteria in areas that are hard to reach.
• Regular brushing: It’s best to brush your teeth with a soft-bristled toothbrush and fluoride toothpaste at least twice daily, ensuring you brush all the tooth surfaces and along the gumline to remove plaque and bacteria.
• Using antimicrobial mouthwash: Rinsing with an antimicrobial mouthwash helps reduce the number of bacteria in your mouth. Ideally, use products containing ingredients like chlorhexidine.
• Maintaining a healthy lifestyle: It’s best to try to maintain a healthy lifestyle by limiting sugary snacks and drinks, eating a balanced diet, and avoiding tobacco use or smoking, as these factors can increase the risk of dental infections.
• Attending regular dental check-ups: Routine dental visits allow your dentist to monitor your oral health, identify early signs of infection or decay, and manage any concerns before they worsen.

Importance of dental care

Oral hygiene is important as it helps prevent complications that can lead to tooth loss and systemic health conditions if left untreated. Other benefits include:

• Preventing tooth decay and gum disease: Regular dental care, including brushing, flossing, and dental check-ups, helps prevent tooth decay and gum disease.
• Early detection of oral health conditions: Routine dental visits allow for the early detection of conditions like cavities, gum disease, and oral cancer, enabling prompt treatment and helping prevent complications.
• Improved overall health: Oral health is closely linked to overall health. Maintaining good oral hygiene can reduce the risk of systemic conditions like heart disease.
• Increased self-esteem: Proper dental care can improve your smile, boost your confidence, and enhance your overall self-esteem and well-being.
• Cost savings: Preventive dental care is usually more cost-effective than treating advanced dental conditions that may arise from not having regular oral health checks.

Summary

Tooth infections can cause significant discomfort and lead to serious complications, like the spread of infection, if left untreated. The most common signs of a tooth infection include persistent tooth pain, swelling, sensitivity, and fever.

A dentist can provide various treatment options, including antibiotics, abscess draining, root canal procedures, or extraction of the affected tooth if needed. 

Maintaining good oral hygiene and seeking routine dental check-ups can help ensure you maintain optimal oral health and prevent tooth and gum infections.
