A broken tooth infection can develop when bacteria enter a damaged area of the tooth. Even a minor crack or chip may provide an opening for bacteria to enter the inner layers of the tooth. Without prompt care, the infection may spread and lead to more serious dental issues.
Identifying the signs and symptoms of a tooth infection helps you take action sooner and protect your oral health.
How A Broken Tooth Leads To Infection
A broken tooth or cracked tooth weakens the outer enamel. If the damage exposes the inner layers, bacteria can travel towards the tooth pulp. The pulp contains nerves and a blood supply. Once infected, this area cannot heal on its own.
When infection reaches the tip of the tooth root, a periapical abscess may form. In other cases, infection may affect the surrounding gum tissue, leading to a periodontal abscess. Both are forms of a dental abscess or tooth abscess.
An infected tooth can cause ongoing inflammation. If a broken tooth infection is left untreated, the infection may continue to spread through the jaw and nearby tissues.
Common Signs And Symptoms
The signs and symptoms linked to a dental infection may vary between individuals. Some people notice immediate pain, while others experience milder discomfort at first.
Common symptoms include:
- Throbbing tooth pain
- Swelling around the tooth or jaw
- Tenderness when chewing
- A bad taste in the mouth
- Red or swollen gums
- Swollen lymph glands in the neck
In more serious cases, tooth infection spreading beyond the tooth can lead to a high fever, difficulty opening the mouth, or even stomach pain if bacteria affect overall health.
An untreated abscess can cause serious health problems if the infection enters the bloodstream.
Causes Of Broken Tooth Infection
A broken tooth infection often begins with:
- Deep tooth decay
- Trauma to the mouth
- Prior dental work that has weakened the tooth
- Existing dental disease
When enamel is damaged, bacteria have easier access to the pulp. Over time, this leads to infection and abscess formation.
Treatment Options
Prompt treatment is essential. If you suspect a tooth infection, visit your dentist as soon as possible.
The appropriate treatment is guided by how advanced the infection has become.
Root Canal Treatment
A root canal is often recommended when infection reaches the pulp. This treatment removes infected tissue and cleans the inside of the tooth. The space is sealed to prevent further infection.
Antibiotics
In some cases, antibiotics may be prescribed to help control the infection. However, antibiotics alone do not cure the source of the problem. The underlying tooth must still be treated.
Drainage Of An Abscess
If a dental abscess has developed, your dentist may need to release the built-up fluid to ease pressure and reduce swelling.
Preventing Future Infections
Maintaining consistent oral care habits lowers the likelihood of developing a broken tooth infection.
Simple steps include:
- Brushing twice a day with fluoride toothpaste.
- Using a fluoride mouth rinse or a fluoride mouth product.
- Attending regular dental check-ups.
- Addressing cracked or broken teeth early.
These habits support strong teeth and reduce the risk of bacteria entering damaged areas.
Final Thoughts
A broken tooth infection is more than just a minor dental problem. Once bacteria reach the inner layers of the tooth, an abscess can develop and spread if left untreated.
Early treatment supports both your tooth and your overall health. If you are concerned about a broken tooth infection or would like guidance on the next steps, you can book a consultation or call (08) 7078 8263.
Note: Any surgical or invasive procedure carries risks. Before proceeding, you should seek a second opinion from an appropriately qualified health practitioner.
