Dental Abscess

Dental Abscess

While enjoying a delicious meal with your friends and family, you begin to feel an ache on your tooth. You excuse yourself and head to the bathroom, there you notice a boil in your gum. You contact your dentist and explain the symptoms, the dentist’s mentions you might be suffering of Dental Abscess; but to better treat you, you should set up an appointment.

Dental Abscess: What is it?

Our teeth can suffer from numerous diseases, when our dentist diagnoses that we suffer from dental abscess an immediate action needs to be taken. Dental abscess is an oral disease in which a collection of pus has set either on your tooth or gums; an abscess that isn't treated can form a fluid-filled bubble (cyst) in the jaw bone. Dental abscess usually occurs when one does not properly treat a dental cavity or a crack or chip tooth, allowing bacteria to enter the tooth.

Cyst: A thin, fluid-filled sac that can appear on the gum tissue, roof of the mouth or lips.

When this occurs the inside of our mouth will hurt and we will feel an irritation, the irritation is caused because of the bacteria that has enter the tooth (even reaching the tooth’s nerve) and have cause an infection. In addition, once bacteria has set on our gums or teeth, you will see a painful swelling filled with pus (a thick, yellowish fluid). When pus is not drain out, the area will get more swollen and you will feel pain.

There are 2 types of dental abscess:

  • Gum Abscess (periodontal abscess): caused by an infection in the space between the tooth and gum. When someone suffers severe periodontal disease, bacteria can build up under the gum and in the bone.
  • Tooth Abscess (periapical abscess): this occurs inside the tooth, the lesion happens when the tooth’s nerve is dead or dying. The abscess will first show at the tip of the tooth’s root and from there can spread to surrounding bone.


There are several symptoms associated with dental abscess, here are the most common:

  • Severe, persistent and throbbing toothache
  • Sensitivity to temperatures (Hot and Cold)
  • Sensitivity to the pressure of chewing or biting
  • Fever
  • Swelling in your face (cheek area and surroundings)
  • Tender or swollen lymph nodes (under your jaw or neck)
  • Sudden rush of foul-smelling in your mouth
  • Sudden foul-tasting fluid in your mouth


This oral illness is cause, as we mention, occurs when bacteria invades the dental pulp (the soft, innermost part of the tooth that contains blood vessels, nerves and connective tissue).

Once bacteria enters the dental pulp (tooth) either through a dental cavity or a chip or crack in the tooth, bacteria can spread and reached all the way down to the root. The bacterial infection will cause swelling and inflammation. The tight space within the inflammation will force pus into a pocket (abscess) at tip of the root.

Diagnosing Dental Abscess

When visiting your dentist, your dentist will examine your oral cavity, examining your tooth and surrounding areas, from here your dentist may conduct a few test:

Lab Tests: the dental laboratory will allow dentist to know what bacteria are causing the infection, helping them target a better treatment option (especially when using antibiotics)

Tapping on the affected tooth: a tooth suffering from dental abscess is generally sensitive to touch or pressure, a few taps can will help your dentist to diagnose.

X-ray: taking an x-ray of the aching tooth can help identify an abscess. X-rays or CT Scans can also be used to determine if the infection has spread.

Treatment Options

One treatment option for dental abscess involves draining the abscess and ridding the area of the infection. Through the examination, your dentist can determine if the tooth can be saved through Root Canal treatment or if Extraction is the best option.

FACT: Leaving a tooth abscess untreated can lead to serious, even life-threatening, complications.

Home Remedy

Dental Abscess is always a serious matter, this infection can easy spread to other parts of the body. To slow down the illness advancement and ease discomfort, you can follow these steps in your home:
