Often, symptoms such as toothache, swelling in this area of the face or persistent sensitivity are ignored or simply camouflaged in the hope that they will disappear spontaneously. However, an infection in the tooth can be more than just a nuisance, becoming, in extreme cases, a life-threatening situation.
In this article, we explain the risks associated with a tooth infection, how to recognize the warning signs and how to treat and prevent these situations. In fact, oral health is directly linked to overall health, so it is important to understand exactly what to do to ensure that unnecessary risks are not taken.
What is a dental infection?
A dental infection occurs when bacteria enter the inside of the tooth or the gum. This complication generally arises due to:
Untreated cavities: If left untreated in time, a dental cavity can reach deeper layers of the tooth, affecting the dentin and eventually the pulp, that is, the inner part which contains blood vessels and nerves, developing the infection.
Dental fractures: A fractured tooth, whether from trauma (such as a fall or blow) or wear (due to bruxism, for example), can expose the internal structures of the tooth, creating a direct entrance for bacteria.
Poorly healed dental interventions: Procedures such as extractions, implants, endodontic treatments (root canals) or even deep cleanings require a healing period. When there is not good oral hygiene after the intervention or when there are failures in this procedure, infections can arise.
Advanced gingivitis or periodontitis: Gingivitis is a mild and reversible inflammation of the gum, but if left untreated, it can progress to periodontitis, a deeper infection that affects the supporting tissues of the teeth.
When the infection occurs, bacteria multiply and can cause symptoms such as pain and swelling, among others.
What are the most common symptoms of a tooth infection?
It is essential to recognize the signs of a tooth infection, which may include:
Severe pain in the tooth or gum;
Sensitivity to extreme temperatures;
Persistent bad breath;
Unpleasant taste in the mouth;
Swelling in the area of the face or jaw;
Fever;
Difficulty opening the mouth or swallowing.
What more serious conditions can arise from a tooth infection?
An untreated dental infection can enter the bloodstream and spread to other parts of the body, such as the neck, jaw, or brain, causing serious complications like:
Sepsis: When the infection enters the bloodstream, it can trigger a widespread inflammatory response. This is a serious medical condition and can lead to organ failure or even death if not treated promptly.
Ludwig's Angina: This is a bacterial infection that spreads to the tissues of the tongue and throat. It can cause breathing difficulties and airway obstruction.
Brain Abscess: In extreme cases, bacteria can even reach the brain, causing an intracranial abscess, which is a rare but potentially fatal condition.
Cardiac Complications: Chronic dental infections, such as periodontitis, for example, can increase the risk of heart problems like endocarditis – an inflammation of the inner lining of the heart – which can pose significant dangers.
It is important to understand that, in most cases, dental infections are treatable. However, it is crucial not to let the problem drag on and to consult a dentist regularly and as soon as any symptoms arise.
How is a dental infection treated?
The treatment of a tooth infection depends on the severity of the infection but may include:
Antibiotics: To combat the bacterial infection and prevent it from spreading throughout the body;
Abscess Drainage: In certain cases, the dentist may make a small incision to release the accumulated pus;
Root Canal Treatment (Endodontics): If the tooth pulp is infected, it is necessary to remove the affected tissue and seal the tooth;
Tooth Extraction: In more severe cases, it may be necessary to remove the affected tooth;
Pain Relievers and Anti-inflammatories: Used to relieve pain and reduce swelling.
When to seek medical help?
If you have any of these symptoms, you should seek a dentist immediately:
Facial swelling that makes breathing or swallowing difficult;
Persistent high fever;
Pain radiating to the ear or neck area.
How to prevent a tooth infection?
The best way to avoid serious complications is to prevent the onset of the infection. Some key measures include:
Maintaining daily oral hygiene, brushing at least twice a day;
Using dental floss daily, ideally before brushing;
Visiting the dentist or an oral hygienist at least every six months for routine check-ups and professional cleanings to identify any potential complications, or whenever any unexpected symptoms arise;
Maintaining a balanced diet;
Avoiding excess sugar and very acidic drinks, which can affect dental health;
Drinking plenty of water to stimulate saliva production, which helps maintain balanced mouth pH;
Not ignoring symptoms.
Any persistent pain, sensitivity, or swelling should be evaluated by a dentist to understand exactly what the cause is and the most appropriate treatment.
Although a tooth infection may seem like a minor issue, if not treated promptly, it can lead to serious complications. Despite this, through simple habits and care, as well as regular visits to the dentist, most infections can be avoided or resolved before they become serious.
